If i'm correct. it should be Macroevolution
2, because a theory is not a law that can not be changed, and new evidence can change a theory.
In the human respiratory system, gas exchange occurs across the cells of the alveoli. Alveoli or an alveolus is the deepest part of the human respiratory system. This part of the respiratory system is a place where gas exchange between oxygen and carbon dioxide occurs from inhaled air to the blood cells<span>.</span>
Answer:
Triploid
Explanation:
The process whereby gametes produced by different sexes of the same species of organism come together is called FERTILIZATION. A gamete is said to be HAPLOID (n) if it contains one set of chromosomes while it is DIPLOID (2n) if it contains two sets of chromosomes.
Hence, if an haploid (n) and diploid (2n) gamete unites, a zygote that is TRIPLOID (3n) emerges or forms. A triploid zygote will have three sets of chromosomes i.e. n + 2n = 3n.
The correct option is D.
Sexual form of reproduction leads to increased genetic diversity as a result of the two different reproductive cells that are coming together and the biological assortment that occur during the process of cell division. Increased genetic diversity enhance variations among living organisms and increased their potentials to survive in their environments.
