Based on the results of the mouse coloration case study, suggest another hypothesis researchers
might use to further study the role of predators in the natural selection process.
Another hypothesis suggested by researchers that can be used to further study the role of predators in the natural selection process is the study of the total or partial absence of predators, visualizing the response in the environment.
What is the role of predators?Predators can act by controlling the population size of some species. When the population size of their prey begins to decrease, many species seek to feed on prey that are in greater abundance in the environment.
With this information, we can conclude that another hypothesis suggested by researchers that can be used to further study the role of predators in the natural selection process is the study of the total or partial absence of predators, visualizing the response in the environment.

Determine of the statement is true or false, and why. Nitrogen makes up most of the atmosphere, but is in an unusable form until converted into an organic form by bacteria.
A. False, it should read, "Nitrogen makes up most of the atmosphere, and is easily converted into an organic form by plants."
B. False, it should read, "Nitrogen makes up a small percentage of the atmosphere, but comes in an easily usable form for most living organisms."
C. True.
D. False, it should read, "Nitrogen makes up most of the atmosphere, in a form easily accessible to plants, who convert for animals to use."
Answer:
C. True.
Explanation:
It should be understood that the the percentage of nitrogen is the highest in the atmosphere. This is because, it make up of more than 60% of the atmosphere. And it should be noted that the atmospheric nitrogen is inform that can not be used by the plant.
Therefore, there is a need for a certain group of bacteria which live in the root noodles of the plants to convert the unused form of the atmospheric nitrogen to a form that can be used by the plants.

How do proteins become embedded in the membrane of the endoplasmic reticulum?a. by splicing of proteins on either side of the ER membrane.b. via stop- and start-transfer sequences that stop and start translocation of a polypeptide through the ER membrane, resulting in transmembrane proteins.c. by post-translational import can results in a transmembrane ER protein.d. by protein chaperones that insert polypeptides into the ER membrane.e. via transit sequences that target polypeptides made in the cytosol for the ER membrane.
Answer:
The correct answer is b.
Explanation:
The signal peptide acts as an initiator of the transfer. Proteins whose first destination is the endoplasmic reticulum have a signal peptide at their amino terminal end that includes a sequence composed of 5 to 10 hydrophobic amino acids, which is recognized by a receptor of this organelle that opens a channel in its membrane allowing such proteins to can get through it. Most of these proteins will then continue their course towards the Golgi apparatus, but those that also have a certain sequence of four amino acids (-Lys-Asp-Glu-Leu-COOH) at their other end (carboxyl terminal) are retained in the endoplasmic reticulum as proteins of this organelle. The transfer stop peptide anchors the protein on the membrane after the ER signal peptide (transfer initiator) is released from the translocator and removed.

Decomposers are an important part of the
ecosystem because
A. they return moisture to the soil
B. they return needed nutrients to the soil
C. they help spread plant seeds
Answer:
the answer correct answer would be B. :)
Explanation:
Without decomposers, dead leaves, dead insects, and dead animals would pile up everywhere. ... Thanks to decomposers, nutrients get added back to the soil or water, so the producers can use them to grow and reproduce. Most decomposers are microscopic organisms, including protozoa and bacteria. (credits to google for explanation)
The Decomposers are an important part of the ecosystem because they return needed nutrients to the soil. The correct option is (B).
By dissolving organic materials, such as dead plants and animals, into simpler molecules, decomposers perform a key function in ecosystems. They return nutrients to the soil by breaking down organic matter. The growth and development of plants depend on minerals like nitrogen, phosphorus, and potassium, which are vital to their growth. Decomposers help the ecosystem's fertility and the overall health of the food chain by recycling these nutrients back into the soil.
They decompose organic materials to replenish nutrients in the soil. Plants require certain elements, such as potassium, phosphorus, and nitrogen, for proper growth and development. By recycling these nutrients back into the soil, decomposers contribute to the ecosystem's fertility and the general well-being of the food chain.
Hence, the Decomposers are an important part of the ecosystem because they return needed nutrients to the soil. The correct option is (B).

Explanation:
Which statement below best summarizes the
likely effects on the carbon cycle of clear-cutting,
or removing all of the trees, in vast areas in a
forest?
A. Clear-cutting would reduce the amount of
carbon dioxide found in the atmosphere.
B. Clear-cutting would limit the amount of nitrogenfixing
bacteria in the area.
C. Clear-cutting would allow for secondary
succession of smaller plants and more carbon.
D. Clear-cutting would increase the amount of
carbon dioxide found in the atmosphere.
Answer:
D. Clear-cutting would increase the amount of carbon dioxide found in the atmosphere
Explanation:
Plants including trees are organisms that help maintain the balance of carbon in the carbon cycle. They do this via the process of PHOTOSYNTHESIS, which is the way they obtain their energy and carbon source. During photosynthesis, trees (plants) absorb carbon in form of atmospheric carbon dioxide (CO2) from the air through the STOMATA on their leaves.
CO2 is an input substance in order for photosynthesis to occur. In a case where all the trees (plants) of a forest has been clear cut or removed, there will be no organisms to directly absorb the carbon dioxide (CO2) released into the atmosphere via respiration. Hence, the amount of carbon dioxide found in the atmosphere would increase.
Answer:
D. Clear-cutting would increase the amount of
carbon dioxide found in the atmosphere.

Carbon dioxide acts as a reactant that combine with water and produces glucose during photosynthesis. Thus, option b is correct.
What is photosynthesis?Photosynthesis is the biochemical event in which the plants produce their food as well as the food for all other organisms by capturing sunlight.
In photosynthesis, carbon dioxide and water from the atmosphere combine to produce carbohydrate, oxygen and energy. Photosynthesis converts light energy to chemical energy through carbon fixation.
Photosynthesis is performed by all the green plants and certain bacteria. As green plants contain chlorophyll, it is the main centre for absorption of sunlight. Splitting of water produces electrons, which are then used for energy production through electron transport chain.
Thus, photosynthesis is important for releasing oxygen into the atmosphere and regulating the amount of carbon dioxide on earth.

The question is above
Hello there! :D
Yes, biology! Love getting some cool science questions. :)
Let's start by reviewing the context of the question:
We know that all living things grow, and that multicellular and unicellular organisms do so in different ways.
How do multicellular organisms grow?
We go through a process called Mitosis for Somatic (body cells), and Meiosis for Gametes (ovum and sperm). We do this to grow and to procreate. Humans are multicellular, so is your dog, Barry B. Benson, and all the beautiful flowers and trees that you see outside in the spring time.
Second question, ya like jazz? Nah, haha. How do unicellular organisms grow?
They grow through expansion! Their only cell grows until it reaches maturity and it begins to split (divide) to form more unicellular organisms. An example of a unicellular organism that does this is yeast, which is in most bread.
Now that we have our context, we can answer this question. What is the topic we talked about this most in covering context? Cell divison!
The answer choice that covers this topic the best is answer "A".
I hope this helps you and you have a wonderful day,

Describe cellular respiration. How do plants and animals help each other in cellular respiration?
Answer:
The oxygen produced by plants during photosynthesis is what humans and animals inhale for the blood to transport to the cells for respiration. ... The process of photosynthesis is used by plants and other photosynthetic organisms to produce energy, whereas the process of cellular respiration breaks down the energy for use.
Explanation:
Answer:
Cellular respiration is the process through which cells convert sugars into energy. To create ATP and other forms of energy to power cellular reactions, cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form.Plants take carbon dioxide during photosynthesis and release oxygen into the atmosphere. Animals and plants take oxygen and release carbon dioxide during respiration. Thus, both plants and animals help each other in the exchange of gases in the atmosphere.

Researchers studying microbial activity at another active oil-spill site found decreasing levels of methane over the course of several months, but no changes in oxygen saturation in any of their repeated samples. How should they interpret these results
Answer:
Methanotrophs.
Explanation:
Methanotrophs are those microbes (bacteria) which feeds on methane or used methane as energy source for their survival. These type of microbes survive by using single carbon compound as a source of energy. So we can say that due to the presence of Methanotrophs, the level of methane decreases while there is no change occurs in oxygen saturation level.
