Answer:
Carbon is a primary component of all known life on Earth, representing approximately 45–50% of all dry biomass.[1] Carbon compounds occur naturally in great abundance on Earth. Complex biological molecules consist of carbon atoms bonded with other elements, especially oxygen and hydrogen and frequently also nitrogen, phosphorus, and sulfur
Explanation:
They are helpful in mate selection rather than being mostly beneficial to survival
The reason the flower is pink, is mainly because when you mix a light color ( in this case a a white flower) in with a red, it creates a pink color. In others words, when you mix white and red, it creates pink. Hope this helped!
The proteins encoded by genes within the same gene family have modularity if structure because : ( D ) gene families usually have similar DNA sequences and therefore similar protein structure.
A gene family is a set of similar genes that is formed by the duplication of single original gene, which has a similar biochemical function. natural selection affects the increase or decrease of a gene family.
Gene families have similar DNA sequence because the genes found in a gene family is from an ancestral gene, also their protein structure is similar
Hence we can conclude that gene families usually have similar DNA sequences and therefore similar protein structure.
