Answer: The cell membranes of a variety of different bacteria, fungi, animal and plant cells contain aquaporins through which water can flow more rapidly into and out of the cell than by diffusing through the phospholipid bilayer.

The step of the cellular respiration pathway that can take place in the absence of O2 is glycolysis, glycolysis is an anaerobic that’s mean it’s does not require oxygen O2
The answer is: Glycolysis
Carrying capacity is the ability of an area to support a population using earth's natural resources. Things like food and water.
The position within the original arginine codon where the point mutation most likely occurred was the second nucleotide. In this case, the mutation was CGA >> CAA.
<h3>Mutations and codons</h3>
A mutation is any alteration in the nucleotide sequence of an organism.
A point mutation is a single base substitution that doesn't change the open reading frame of a given protein.
In this case, the CGA codon encodes for Arginine, whereas the CAA codon encodes for Glutamine, thereby the mutation likely occurred in the second base (C<u>G</u>A >> C<u>A</u>A)

If I assume that random segregation of chromosomes takes place during spermatogenesis and all sperms are viable then I will take the male through meiosis.
The three chromosomes are +, +, ey
Then you double them into sister chromatids which is ++, ++, eyes.
If I consider all possible alignments during metaphase as, the three homologous pairs and gather at the metaphase plate.
Remember that any two of the three pairs will join together and odd pair out will line up at the metaphase plate with no partner pair.
There are three different arrangements which are possible for the three homologous pairs.
Two of the three possible arrangements will segregate and make two sperm with +ey and two sperm with +. The other arrangement will segregate and make two sperm with ++ and two sperm with ey.
When meiosis is being done, then the sperm genotypes and their proportions are,
1/3+ey, 1/3+, 1/6++, 1/6ey
