Why can oxygen pass through the cell membrane by simple diffusion

Biology
1 answer:
Gekata [30.6K]4 years ago

Nonpolar and small polar moleculescan pass through the cell membrane, so they diffuse across it in response to concentration gradients. Carbon dioxide and oxygen are two molecules that undergo this simple diffusion through the membrane. The simple diffusion of water is known as osmosis.

Individuals in a population of purple people earters are polymorphic at a single locus that leads to variation in purple people
Allisa [31]

Answer:

The correct answer is - overdominance.

Explanation:

In the given question, genotype Pp is a heterozygote condition that has a 54% survival rate or fitness thus these individual people get more chance of mating and increase in number as compared to the other two conditions of PP or pp traits where PP has 45% survivability, less than heterozygous condition and more than pp that has only 4% rate.

It results in a normalizing selection model of natural selection as a moderate trait, that is heterozygote, is selected. Thus, the selection of overdominance which means heterozygote condition produces a better phenotype than PP or pp parents is heterosis.
