where they execute important functions. The polypeptide chain of these proteins must cross the lipid bilayer. This presents a pr
spin [16.1K]

Answer:

In this case, it is likely that the polypeptide chain assumed an alpha helix configuration because the lipid bilayer did not have beta-barrel proteins.

Explanation:

A polypeptide chain is naturally polar, however, a lipid bilayer is naturally non-polar. This makes it difficult and even prevents the polypeptide chain from crossing a lipid bilayer, since the composition of these two elements does not allow them to mix. In that case, the polypeptide chain has two options to take to successfully cross the lipid bilayer.

The first option that the polypeptide chain has is to allow the creation of twisted beta sheets in the shape of a closed barrel in its structure. This only works if the lipid bilayer has beta barrel proteins in its composition to act as a transport channel for the polypeptide chain. However, few lipid layers have this protein.

Most likely, the polypeptide chain assumes an alpha helix conformation to cross lipid bilayers that do not have beta-barrel proteins. By assuming the beta conformation, the polypeptide chain reinforces the hydrogen bonds present in its composition, allowing it to cross the lipid bilayer without having its conformation and structure disassembled.

What discovery could provide evidence against the theory of evolution?
Viefleur [7K]
A discovery that could provide evidence Against the theory of evolution is: If a primate and a trilobite fossil were found in the same rock layer. Because if that were to happen, then that means that trilobites and primates were from the same time frame, and it also means that primates did not evolve that they were the same since they first lived on the earth.

Question 8 How would you describe the effect of different magnitudes of the same factor on the number
Ghella [55]

Answer:

Let's start off with an example. Imagine a population of organisms—let's say, deer—with access to a fixed, constant amount of food. When the population is small, the limited amount of food will be plenty for everyone. But, when the population gets large enough, the limited amount of food may no longer be sufficient, leading to competition among the deer. Because of the competition, some deer may die of starvation or fail to have offspring, decreasing the per capita—per individual—growth rate and causing population size to plateau or shrink.

Explain the difference between renewable and nonrenewable resources and give an example of each.
Lelu [443]

Answer:

Nonrenewable Resources take longer to be replenished, reneweable resources are easily replenished and easily accessible.

Explanation:

If something is Nonrenewable; for example fossil fuels like coal, oil, and natural gas, then that means that the organic matter is limited and not going to grow or be created easily on Earth.

Renewable Resources are usually classified into five categories; Hydro, Solar, Wind, Biomass, and Geothermal. All of these resources are easily accesible and can be used as a natural energy source.

Hope this helped :)
