As you read, think about the following: How can the excretory system be compromised?

1
Why drink water?
2
It's always a good idea to drink plenty of fluids, especially when you have been exercising. Drinking plenty of water helps to flush away materials that might form kidney stones. Staying hydrated is the best way to prevent kidney stones.
Problems of the Excretory System
3
The urinary system controls the amount of water in the body and removes wastes. Any problem with the urinary system can also affect many other body systems.
Kidney Stones
4
In some cases, certain mineral wastes can form kidney stones (Figure below). Stones form in the kidneys and may be found anywhere in the urinary system. Often, stones form when the urine becomes concentrated, allowing minerals to crystallize and stick together. They can vary in size, from small stones that can flow through your urinary system, to larger stones that cannot. Some stones cause great pain, while others cause very little pain. Some stones may need to be removed by surgery or ultrasound treatments.
5
A kidney stone. The stones can form anywhere in the urinary system.
6
What are the symptoms of kidney stones? You may have a kidney stone if you have pain while urinating, see blood in your urine, and/or feel a sharp pain in your back or lower abdomen (the area between your chest and hips). The pain may last for a long or short time. You may also have nausea and vomiting with the pain. If you have a small stone that passes on its own easily, you may not experience any symptoms. If you have some of these symptoms, you should see your doctor.
QUESTION 1 DOK 3 NO STANDARD
Why does the author argue that "staying hydrated is the best way to prevent kidney stones?"

What are kidney stones?
When do they form: When a person has drank a lot of water or not enough water?
Kidney failure
7
Kidney failure happens when the kidneys cannot remove wastes from the blood. If the kidneys are unable to filter wastes from the blood, the wastes build up in the body. Kidney failure can be caused by an accident that injures the kidneys, the loss of a lot of blood, or by some drugs and poisons. Kidney failure may lead to permanent loss of kidney function. But if the kidneys are not seriously damaged, they may recover.
8
Chronic kidney disease is the slow decrease in kidney function that may lead to permanent kidney failure. A person who has lost kidney function may need to get kidney dialysis. Kidney dialysis is the process of filtering the blood of wastes using a machine. A dialysis machine (Figure below) filters waste from the blood by pumping the blood through a fake kidney. The filtered blood is then returned to the patient’s body.During dialysis, a patient’s blood is sent through a filter that removes waste products. The clean blood is returned to the body.

Urinary tract infections (UTIs)
9
Urinary tract infections (UTIs) are bacterial infections of any part of the urinary tract. When bacteria get into the bladder or kidney and produce more bacteria in the urine, they cause a UTI. The most common type of UTI is a bladder infection. Women get UTIs more often than men. UTIs are often treated with antibiotics.
10
Most UTIs are not serious, but some infections can lead to serious problems. Long lasting kidney infections can cause permanent damage, including kidney scars, poor kidney function, high blood pressure, and other problems. Some sudden kidney infections can be life threatening, especially if the bacteria enter the bloodstream, a condition called septicemia.
11
What are the signs and symptoms of a UTI?
- a burning feeling when you urinate,
- frequent or intense urges to urinate, even when you have little urine to pass,
- pain in your back or side below the ribs,
- cloudy, dark, bloody, or foul-smelling urine,
- fever or chills.
12
You should see your doctor if you have signs of a UTI. Your doctor will diagnose a UTIs by asking about your symptoms and then testing a sample of your urine.
QUESTION 3 DOK 1 NO STANDARD
What is a UTI and why is it problematic?
EXTRA HELP
What is a UTI? Refer back to paragraph 9.
What is problematic about UTIs? Refer back to paragraph 10.
Summary
Disorders of the urinary system include kidney stones, kidney failure, and urinary tract infections.
Kidney dialysis is the process of filtering wastes from the blood using a machine.

Approximately 20% of the world’s adult population are able to digest milk sugar (lactose).They are “lactose tolerant.” This trait is known to be controlled by a single dominant gene. Therefore, we would expect that
no lactose tolerant individuals have two biological parents that are lactose INtolerant.
all lactose tolerant individuals to be heterozygous for the gene.
60% of lactose INtolerant individuals would be heterozygous.
all children of lactose tolerant parents will also be lactose tolerant.
Answer:
No lactose individuals have two biological parents that are lactose intolerant
Explanation:
In this case lactose intolerance would be coded for a recessive gene (r). if both parents are lactose intolerant the would both be the genotype (rr) . For individual to be lactose intolerant atleast one parent most be lactose tolerant posesing the dominant (R) gene. Which both parents in this example lack.
Tina is studying chipmunks in a field of 900 square meters. In 2020, she counts 194 chipmunks. In 2021, she counts 231 chipmunks. What is the population density of chipmunks in 2021?
Answer:the population density of chipmunks in 2021=256,666.667 per square kilometres
Explanation:
Population density is defined as the number of population per unit area of land
which can be expressed as
Population density =number of population/ land area
Since land area is usually given in square kilometres or square miles we convert 900 square meters to square kilometres
1 square kilometres =1000000 square meters
900 square meters=900/1000000=0.0009 square kilometres
Therefore, the population density of chipmunks in 2021= 231/0.0009 square kilometres =256,666.667 per square kilometres

Why is it important for an organ system to interact with other organ systems?
Answer:
Just as the organs in an organ system work together to accomplish their task, so the different organ systems also cooperate to keep the body running. For example, the respiratory system and the circulatory system work closely together to deliver oxygen to cells and to get rid of the carbon dioxide the cells produce.

Complete question:
You are studying a biochemical pathway in the mold Neurospora where enzyme 1 converts the initial substrate into intermediate substrate A; enzyme 2 converts intermediate substrate A into intermediate substrate B; enzyme 3 converts intermediate substrate B into intermediate substrate C; and enzyme 4 converts intermediate substrate C into the end product, an amino acid that is essential for growth. You isolate a mutant that is unable to grow on minimal media. Which data would provide the strongest support for the hypothesis that this mutation occurred in the gene that codes for enzyme 2?
a. The mold can grow on rich medium plus intermediate substrate C, but not on rich medium plus intermediate substrate B.
b. The mold can grow on minimal medium plus intermediate substrate B, but not on minimal medium plus the initial substrate.
c. The mold can grow on minimal medium plus intermediate substrate B, but not on minimal medium plus intermediate substrate A.
d. The mold can grow on rich medium plus intermediate substrate D, but not on rich medium plus intermediate substrate C.
e. The mold can grow on minimal medium plus intermediate substrate A, but not on minimal medium plus intermediate substrate C.
Answer:
c. The mold can grow on minimal medium plus intermediate substrate B, but not on minimal medium plus intermediate substrate A.
Explanation:
Let us first diagram the pathway for a better understanding.
The normal organism produces four enzymes that convert substrates in the medium that allow it to survive, grow, and reproduce.
initial substrate ------------> A ----------------> B ----------------> C ----------------> AA
Enzyme 1 Enzyme 2 Enzyme 3 Enzyme 4
Any mutation on the Neurospora´s enzymes will not let the organism grow on the minimal medium because it will not be able to convert the minimal substrate into the following one, because the mutated enzyme will not accomplish its original function.
So if the mutation occurs in enzyme 1, the organism will not be able to convert the initial substrate into intermediate substrate A. And the rest of the reaction will not be possible either because of the lack of substance A.initial substrate -----X----> A -------X-----> B ------X--------> C ------X-------> AA
mutated Enzyme 1 Enzyme 2 Enzyme 3 Enzyme 4
If the mutation occurs in enzyme 2, the organism will not be able to convert the intermediate substrate A into intermediate substrate B. And the rest of the reaction will not be possible either because of the lack of substance B.
initial substrate ------------> A -------X--------> B -------X------> C --------X-----> AA
Enzyme 1 mutated Enz. 2 Enzyme 3 Enzyme 4
If the mutation occurs in enzyme 3, the organism will not be able to convert the intermediate substrate B into intermediate substrate C. And the last reaction will not be possible either because of the lack of substance C.
initial substrate ------------> A ----------------> B -------X--------> C -------X------> AA
Enzyme 1 Enzyme 2 mutated Enz. 3 Enzyme 4
And if the mutation occurs in enzyme 4, the organism will not be able to convert the intermediate substrate C into the essential amino acid.
initial substrate ------------> A ----------------> B ----------------> C -------X-------> AA
Enzyme 1 Enzyme 2 Enzyme 3 Mutated Enz. 4
But, if we artificially add to the medium the substrate that should be produced by the original enzyme (and that is not converted because of the mutation), then the organism will grow and survive because the other enzymes will be able to produce the essential amino acid.
So, if enzyme 2 is the only enzyme mutated, the organism will not be able to live in a medium with substrate A because the mutated enzyme will not convert the substrate A into B. There will not be B substrate in the medium, and the other enzymes will not produce the essential amino acid. So if the mutation occurs in enzyme 2, substrate A is useless to the organism because it will not survive.
But if we add the intermediate substrate B to the medium, the organism will survive. In a medium with substrate B, all the other reactions will be possible, and the organism will get the essential amino acid. The artificial addition of B substrate will replace the function of the original enzyme 2 -which is the one that converts A into B-.
Clams that are native to China are living in the San Francisco bay. How can these clams damage the bay ecosystem?
Answer:
Marine Invasive Species are animals or algae that have been translocated from their native region to California marine and estuarine waters. Invasive species are also called introduced, exotic, alien, nonindigenous or non-native.The introduction of NIS can cause harm to the ecosystem by displacing native species, becoming a human health dangerby introducing new diseases, or cause economic havoc on commercial, agricultural, or recreational activities by clogging waterways, and impacting navigation and recreation.
A prime example of the harm an invasive species can cause is Caulerpa taxifolia, also known as Killer Algae, a strain of green seaweed believed to be released from an aquarium directly into a water body or through a storm drain. The Killer Algae forms a dense carpet on any surface including rock, sand, and mud displacing native plants and animals, disrupts the natural food chain, and seriously impacting recreational and commercial fisheries.
Although Caulerpa was successfully eradicated from California marine waters, few eradications have been attempted due to perceived challenges and high cost (over $7M was expended in the case of Caulerpa).
Number of Invasive Species Statewide
The map below shows that all major harbor areas and Bays in California have received significant NIS introductions. San Francisco Bay has the highest number of non-native species, followed by the Ports of Los Angeles/Long Beach. San Francisco Bay is a hotspot for invasions because it has high recreational boating and commercial shipping traffic, a history of oyster culture, and is adjacent to a highly urbanized area. Our research found that San Francisco Bay is a hub for the spread of NIS to the rest of the West Coast.

A quote often attributed to Mark Twain states, "What gets us into trouble is not what we don't know. It's what we know for sure that just ain't so." How does this relate to Pangaea and the Theory of Plate Tectonics? Ted talk
Answer:
Land masses moves as the movements of the tectonic plates causes the movement of the huge land masses like the Pangaea.
Explanation:
Mark Twain was a great American writer and lecturer. He is also known greatest humorist that the United States of America has ever produced.
By the statement of Mark Twain, it relates to the idea of the Pangaea and the theory of the tectonic plates. The very idea that the early continents were fitted together was being rejected by many for a long time as it was unbelievable for many that the huge land masses can move. But this turned out to be true later on.

Determine if the following statement is true or false, and why. “Everyone who
carries a faulty allele develops a disease."
A. False, it should read, "No one who carries a faulty allele develops a disease."
B. False, it should read, "Some people who carry a faulty allele develop a disease, some
are carriers."
C. True
D. False, it should read, "No one who carries a faulty allele becomes a carrier."
The statement "Everyone who carries a faulty allele develops a disease" is absolutely false. This is because some people who carry a faulty allele develop a disease, some are carriers. Thus, the correct option is B.
What is an Allele?An allele may be defined as one or two or more alternative forms of a gene. An individual always inherits two alleles, one from each parent that shows characteristic traits for any given genomic location where such variation exists.
If the two alleles are the same, the individual is homozygous for that allele. While, if the two alleles are non-identical, the individual is heterozygous for that allele.
It is not possible that everyone who carries a faulty allele develops a disease because it depends on the expression of the disease, whether it is dominant or recessive, sexual or autosomal, etc.
Depending on the same principle, some are affected by the disease when both alleles have the same traits while some are carriers.
Therefore, the correct option for this question is B.

9. why Energy released by aerobic and anaerobic respiration in animal are not same.
Answer: Anaerobic respiration produces a relatively lesser amount of energy as compared to aerobic respiration, as glucose is not completely broken down in the absence of oxygen. In animal cells anaerobic respiration often occurs during exercise. The glucose does not get fully broken down in this process, so it does not release its full potential energy. Instead of carbon dioxide and water it breaks down to form lactic acid and a small amount of energy.

Why is it important for soil to contain nitrogen, phosphorus, magnesium, and potassium??
Answer:
Soil is one of the main sources of nutrients needed by plants in order for them to grow. Nitrogen is used by plants for lots of leaf growth and good green color. Phosphorous is used by plants to help form new roots, make seeds, fruit and flowers. Potassium helps plants make strong stems and keep growing fast. It's also used to help fight disease. Magnesium is the central core of the chlorophyll molecule in plant tissue.
Explanation:
Hope this helped a little bit.
Answer:
Explanation:
1.Without enough nitrogen in the soil the plant cannot grow taller, or produce enough food.
2.phosphorus results in higher grain production, improved crop quality, greater stalk strength, increased root growth, and earlier crop maturity. That is important because crops take up phosphorus only from the soil solution.
3.The role of Magnesium in the soil is the central core of the chlorophyll molecule in plant tissue. Thus, if Mg is deficient, the shortage of chlorophyll results in poor and stunted plant growth. Magnesium also helps to activate specific enzyme systems.
4. Potassium is a critical nutrient that plants absorb from the soil, and from fertilizer. It increases disease resistance, helps stalks to grow upright and sturdy, improves drought tolerance and helps plants get through the winter. Potassium triggers activation of enzymes and is essential for production of (ATP).Both uptake of water through plant roots and its loss through the stomata are affected by potassium.
