What effect might high temperature or irregular pH levels have on facilitated diffusion?

Biology
1 answer:
Liono4ka [1.6K]3 years ago
8 0

Answer:

  The facilitated diffusion is a type of passive transport affected by different factors including the temperature and the pH level. The facilitated diffusion process is produced by proteins that enable the movement of molecules between both sides of the cell membrane.  

   The pH level depends on the ion gradient and this factor modifies the diffusion rate of the buffers between both sides of the cell membrane. Moreover, the temperature is a factor that modifies the ionic charge of molecules, as well as the structure and the porosity of pores that facilitate the interchange between both sides of the cell membrane

Populations evolve for many reasons. Suppose there is a population of plants that have either purple flowers or white flowers, a
sattari [20]

Answer: natural selection

Explanation:Natural selection, gene flow, gene drift and mutation are the mechanisms for EVOLUTION.

The dominant purple allele must have been acquired from previous parent gene, by natural selection

Definitely the available   alleles from previous flower population were white and purple flowers. But, because the parents of purple flowers exhibit VARIATION, in their gene pool,  they showed dominance over  the recessive white colour flowers in the same population.  

◼ from Darwin’s observation and deduction, Organisms who acquired certain characteristics from variation  tend to survive than others, and therefore pass these inheritable characteristics to their offspring.

◼Thus the purple flowers dominated the population for the available resources, among the other flowers colours, (competitions) therefore it leads to a stable population in size after a period of time., while the white colour flowers are recessive

◼Darwin concluded that, variants of best adaptation will be selected for by natural conditions operating in the environment of the population at that particular period (natural selection).

Based on this, natural selection takes place, and the purple flowers with best variation will have selective advantage (dominance)above white colour flowers(recessive).

Consequently, they have higher survival rates compare to white flowers in the population this is   survival of the fittest by natural selection of purple flowers

The frequency of the white colour flower will reduced because of less manifestation of traits from generation to generation from reduced gene pool due to recessive trait, however the frequency of Purple flower will increase because the number of copies of allele of purple flowers is greater than the total number of all the flowers population( white flowers+purple)

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.
