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?

Answers

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 soil to contain nitrogen, phosphorus, magnesium, and potassium??

Answers

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.

In bacterial cells treated with Mupircin, would you still expect to find large or small amounts of mRNA inside of the cell?

Answers

Answer:

Yes.

Explanation:

Yes, we can expect to find small amounts of mRNA inside the bacterial cell because the Mupirocin kills the bacteria by inhibiting transfer RNA. Mupirocin is an antibiotic used to kill the bacteria present on the skin. It destroys the cellular structure of bacteria and prevent the bacteria from causing more infection. Mupirocin do its antimicrobial activity by inhibiting isoleucyl-transfer RNA, as a result inhibiting of bacterial protein and RNA synthesis occurs.

Answers

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-.

9. why Energy released by aerobic and anaerobic respiration in animal are not same.​

Answers

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.

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

C. True
D. False, it should read, "No one who carries a faulty allele becomes a carrier."

Answers

B.False. it should read, “Some people who carry a faulty allele develop a disease, some are carriers “

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.

Clams that are native to China are living in the San Francisco bay. How can these clams damage the bay ecosystem?​

Answers

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.
