Answer:
The correct option is (b).
Explanation:
Due to high temperature and excessive motion, sweating is triggered. When Nitrogen based compounds breaks down, ammonia is produced. As ammonia is very much toxic for body, so its gets converted to urea. Urea is excreted by sweat glands. It also secretes sodium, water along with urea. Hence, the correct option is (B) "urea".
Urea is excreted by sweat glands in repense to the break down of proteins and the formation of ammonia.
Urea is one of the organic chemical components of urine that dissolves in alcohol and water and has the ability to crystallize.
Urea is produced when proteins are metabolized and elements that have nitrogen are degraded.The process that leads to the formation of this chemical compound is known as the urea cycle, animals that excrete amine nitrogen such as urea are classified as ureotelic.On the other hand, if the expulsion of amine nitrogen occurs as ammonia, the organisms are called ammonothelic.Therefore, we can conclude that urea is a substance that is formed in the body during the processing of proteins and nitrogen compounds in the liver.

What exercise is most appropriate for testing muscular endurance?
A. Push-up
B. Bench press
C. Back squat
D. Bicep curl
Answer:
Push ups
Explanation:
Muscular endurance is when the muscle have the ability to withstand and sustain contractions that is constantly occur for a long period of time. It include the amount of repeated single exercise that the muscle can endure without resting. It ensures muscular fitness, muscular strength and power.
A good example of muscular exercise is push up the ability to constantly do it for a long time without rest or stopping.
The push-up is the most appropriate exercise for testing muscular endurance. Therefore, the correct option is A.
Muscular endurance is the ability of a muscle or group of muscles to sustain repeated contractions over a prolonged period of time.
The push-up specifically targets the chest, shoulders, triceps, and core muscles. It requires maintaining a plank position and lowering and raising the body by bending and extending the elbows.
By performing as many push-ups as possible without compromising form, an individual can assess their muscular endurance level.

An ostrich and an emu are both flightless birds found on completely different continents (ostrich in Africa, emu in Australia). These birds have slightly different evolutionary histories, but have independently evolved similar adaptations due in part to the similar habitats they occupy. What type of evidence for evolution do these birds present
Answer:
The correct answer is "Biogeography".
Explanation:
The missing options for this question are:
-Comparative embryology
-Biogeography
-Bioinformatics
-Fossils
The correct answer is "Biogeography".
Biogeography is a field of study focused on how species have changed over its evolutionary history regarding its distribution and geographical localization. Biogeography particularly examines biological diversity patterns. The evidence of evolution between the ostrich and the emu populations is of biogeographical type, since they are located in different regions but they are exposed to similar habitats.

Students in a science class were asked to investigate how missing or damaged
organelles affect cellular homeostasis for cells found in muscle tissues.
Which of the following questions should they ask to determine if these muscle cells
are functioning properly? (AKS 151)
At what rate do the chloroplasts of the cell need to capture enough sunlight to
meet the high energy needs of the cell?
At what rate do the ribosomes of the cell need to work to produce enough
glucose to meet the high energy needs of the cell?
At what rate do the mitochondria of the cell need to convert glucose to usable
energy molecules to meet the high energy needs of the cell?
At what rate does the cell wall need to break down its carbohydrate structure to
meet the high energy needs of the cell?
Answer:
At what rate do the mitochondria of the cell need to convert glucose to usable
energy molecules to meet the high energy needs of the cell?
Explanation:
Organelles are organ-like structures found in cells. The are responsible for the specific actions carried out by each cell. Each organelle has its own specific role to play. However, missing or damaged organelles can have effects on the cells.
Mitochondria are organelles found in cells of all eukaryotic living organisms e.g animal, plants as they are responsible for the synthesis of energy in form of ATP. Since the cells being investigated in this question is a MUSCLE CELL, which is only found in animals, then an appropriate organelle must be investigated.
The appropriate to be asked to know if muscles cells are functioning properly is: At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell?.
Note that, other options are incorrect because muscle cells do not have chloroplast and cell wall, while ribosomes are not site for glucose production.

At which stage of development does the embryo implant in the uterus?
Answer:
Blastocyst stage
Explanation:
A baby undergoes different stages of development before they become fully matured. It all begins with the process of fertilization which involves a sperm cell coming in contact with an egg.
After a successful fertilization, the fertilized egg travels down to the uterus where it undergoes series of cell division till it becomes a stack of arranged cells known as the blastocyst.
During the blastocyst stage, the embryo fastens itself to the edge of the uterus, this process is known as implantation.
Hence, the embryo implants in the uterus during the blastocyst stage.

A farmer in Minnesota plants some tomato seeds in early spring. She plants them outdoors in soil and adds water every day. A few weeks later, nothing has happened. What is the most likely reason the seeds have not germinated?
Answer:
Other factors could affect the reason the seed didn't germinate because under suitable conditions depending on the variety it should germinate within 5 to 10 days from planting. However, the most likely reason it didn't germinate must be the Temperature.
Explanation:
From the question above, the farmer lives in Minnesota and she planted between March and May, meaning the temperature was way cold which is not suitable for tomato. One other valuable point was she planting outdoor which could also affect the performance of the tomato seedlings. Planting in early spring doesn't necessarily mean bad as some seeds might thrive under conditions explained above. For tomato, depending on temperature because too high temperatures could also affect the viability of the seeds. In Minnesota in early spring, it would have been better if she planted indoors to raise the temperature before transplanting as a balanced night temperature is also important for the seed viability.
Some other factors to be considered for seeds to germinate:
1. Water
2. Type of the soil
3. Seed depth in the soil
4. Nature of seed coat
5. Oxygen
6. Light

In aquatic ecosystems, phytoplankton and other photosynthetic organisms appear in the upper layer of the water, but not deeper layers. Which statement explains this distribution?
ANSWER :
The deeper layers are too dark for photosynthesis to occur.
Explanation:
Photosynthesis is a unique process to autotophic organisms. It involves the use of light energy from the sun to manufacture organic molecules (food). As the phenomenon implies i.e. PHOTO - LiGHT, light is an unnegotiable requirement for photosynthesis to take place. Autotrophs are able to perform this process because they contain pigments (Chlorophyll) that can trap energy from sunlight.
In an aquatic ecosystem, phytoplanktons and other photosynthetic organisms like aquatic plants are the autotophic organisms. They are found in the upper layer of the water so that they can reach light from the sun. The light from the sun cannot travel deep down the water making the deep parts of the ocean be deprived of light.
This is the reason why photosynthetic organisms cannot be found in the deep parts of the water as they will be unable to have access to the light from the sun in order to perform photosynthesis.

which of the following is most consistent with the modern theory of evolution
The correct answer is Parents pass their physical traits to their offspring; those offspring with traits that help them survive in their environment are able to reproduce.
Explanation:
The modern theory of evolution explains the mechanisms that make organisms change. One of the main ideas this theory proposes is that organisms with traits that help them survive or reproduce have higher chances to pass their genes and traits to new generations. This mechanism makes certain traits to be favored and contributes to the evolution of organisms because after multiple generations certain traits will prevail while others will be eliminated.
Moreover, this theory specifies genes in an organism are not acquired or modified during its life but these are the results of the traits passed to the organism by its parents and evolution occurs only after a long time or multiple generations. According to this, the first option is the correct one.
Why is it important to understand both physics and chemistry when studying living things?
answer: both aspects , sameness &variety are the result of biological evolution.
All fish nitrogen into the water as ammonia and organic nitrogen. These chemicals are byproducts of their metabolism and respiration.
Answer:
The correct answer would be - release/excretes.
Explanation:
In ponds, rivers, or similar ecosystem nitrogen cycle is completed with the help of the fishes. In this ecosystem, the nitrogen cycle initiates with the eating plants or fish food by the fishes and performs metabolism and cellular respiration which produces byproduct ammonia and organic nitrogen as animal waste.
This waste is released or excreted by the fish in the water where the beneficial bacterium helps in restoring nitrogen back to the atmosphere by breaking these wastes.

Describe the type and ratio of organisms you would expect to find in a lake in a national park. give evidence to support your answer
Answer:
Algae would be the organism in greatest proportion in a lake in a national park.
Explanation:
A lake in a national park would have algae proliferation, which would be the largest organism in that lake. This is because a lake in a national park is subjected to great incidence of sunlight and large amounts of oxygen. This would facilitate and stimulate the reproduction of algae on a large scale, causing them to develop in the substrate, stones, pebbles, and in the water itself.
