Answer:
The answer is c. W,X,Z
Explanation:
According to the evolutionary timeline:
- (W) In 1798, Thomas Robert Malthus published an essay, "An Essay on the Principle of Population." Malthus proposed that the current rate of population growth would deplete current resources.
- (X) 1809 marked the publication of the first theory of evolution. Jean Baptiste Lamarck proposed that evolution occurred through the inheritance of acquired characters.
- (Z) In 2003, Wayne State University School of Medicine's Dr. Morris Goodman conducted studies that revealed a 99.4% genetic similarity between human and chimpanzees. This sparked a debate in the scientific community whether to include chimpanzees in the genus, Homo.
- * If Y is part of the choices, it comes after (X).
That would be B.
A pairs with T(or U in RNA).
C pairs with G.
Chemotrophs (Bacteria) are essential in the conversion of nitrogen containing compounds to nitrogen forms that are accessible and usable by plants.
I believe what you are looking for is Chemotaxis.
I found the whole exercise on the internet. Attached is the scheme with labels for the gametes, f2 generation, and respective frequencies.
For the gametes position, on the left pink square on the male gametes side you should put a capital G, <span>and on the right pink square on the male gametes side you should put a small g, as</span> the only two possible offsprings that are showing is "GG" under the left male gamete and "gg" under the right male gamete. On the top pink square on the female gametes side you should put a capital G, and on the bottom pink square on the female gametes side you should put a small g, as the only two possible offsprings that are showing is "GG" on the same line as the top female gamete and "gg" on the same line as the bottom female gamete.
As for the frequencies of the gametes, you should put the white label that marks 1/2 by the side of each gamete.
Related to the F2 generation, the top right and bottom left pink squares should have the label with a capital G and small g - "Gg" which reflects the combination of the male gamete on its line with the female gamete also on its line.
As for the frequencies of the progeny, each of the genotypes formed from the union of the gametes should have by the side the white label that marks 1/4.
The totals would be that GG is 1/4, Gg is 1/2 (1/4+1/4), and gg is also 1/4.
