I think b. Proteins are polymers of amino acids is the correct answer
Answer:
The two forms interbreed and their offspring survive and reproduce well.
Explanation:
When talking about classification of species, one of the first features observed is the species fitness, which describes the reproductive success or their ability to leave to their successive generations the most copies of their genotype. When different species that were recently divided into 2, by geographic isolation, for instance, usually there is no genetic compatibility, and if its possible to produce offspring, there might be some development issues like infertility.
Since the liver is the primary organ for metabolism, then in the setting of liver injury there will be reduced metabolism of compounds such as hormones. If these hormones are not metabolized and degraded in the liver, then these hormone levels will increase.
<em>A particular example is that the hormone estrogen is increased in the setting of liver damage, causing males with liver failure to have feminine characteristics.</em>
B. Scarcity of drinking water
Answer:
Similarities in structure among distantly related species are analogous if they evolved independently in similar environments. They provide good evidence for natural selection. Examples of evidence from embryology which supports common ancestry include the tail and gill slits present in all early vertebrate embryos
