Answer:
Yes...This is an example of speciation by natural selection
Explanation:
As we know that natural selection always promote those evolutionary changes that are necessary. Changes that happen in chromosome number always promote with a specie that is closely related to the parent specie and produce fertile off-springs. These new generations are most adaptable and can survive in the environment more efficiently than the previous ones.
Additionally, other than natural selection, speciation can also happen as a result of random mutations, genetic drift and by means of artificial selection as well. But the natural likelihood of all these is probably low as compared to that of natural selection.
Cellular respiration is a metabolic process that converts glucose and utilizes oxygen to generate the energy needed to carry out system processes, specifically ATP. The by-products produced from the process includes water and carbon dioxide.

Answer:
The cell membrane acts as a barrier that protects the cell from the external environment and it regulates the movement of the particles or substances in and out of the cell.
Answer:
Punnett square is a square diagram which is used to predict the genotype of the offspring produced by particular cross.
Let P and p be the alleles of the gene responsible for the flower colors in a plant.
The genotype of both the parents is given as heterozygous that is, Pp.
Two types of gametes would be formed P and p.
The cross is shown in the image below.
The cross would be result in offspring with three types of genotypes PP, Pp and pp in 1:2:1.
