What cell membrane structure allows water-soluble materials to be passively transported to the cytoplasm?

Biology
1 answer:
monitta3 years ago
3 0

Answer:

B. Carrier proteins

Explanation:

Water-soluble materials, such as glucose, amino acids, and ions, need help to cross the membrane because they are repelled by the hydrophobic tails of the phospholipid bilayer. The tails are not hydrophilic.

Endocytosis vesicles are an example of active transport, they require energy to allow large molecules to be taken into the cell through a system of vesicles.

Golgi complex vesicles deliver proteins and other macromolecules outside of the cell from the inside.

Carrier proteins can participate in both active and passive transport across cell membranes. For example, carrier proteins with channels can help molecules cross the membrane passively.

pishuonlain [190]

You have a population in hardy-Weinberg equilibrium for the m and n alleles. These alleles are codominant.  Allele frequency of m is 0. 4. 0.48 is the frequency of heterozygotes in the population.

An allele frequency has been computed by dividing the total quantity of copies of each of the alleles at that specific genetic location in the population by the number of points of time the allele of interest has been observed in a population.

The frequency of each genotype is typically calculated by dividing the population's total count of individuals by the number of people who have that genotype.

The number of differences between cytochrome c of humans and cytochrome c of other organisms is as follows: Rhesus monkey - 1 di
liubo4ka [24]

Answer:

The species that will be most similar to humans will be

1. rhesus

2. pigeon

3. fruit fly

Explanation:

Evolution can be described as the process in which different organism evolve from common ancestors over a long period of time. Evolutionary studies show that some organisms have more shared characteristics as compared with other organisms. These organisms with common characteristics are believed to be closer to one another and evolved from the same ancestors.

In the above question, as there is only one difference between the cytochrome c of humans and rhesus, hence rhesus is the closest to humans. Pigeons has lesser number of differences than fruit fly, hence it is second on the list. Fruit fly has the maximum differences hence it is placed last.
