Answer:
in many ways
Explanation:
if the animal does not receive the same nutrition that it would in the wild, the animal will become weaker. If the climate of the zoo is very different than the animals natural habitat, they will struggle to maintain homeostasis. If a dolphin, for example, is in a tank that is too small, it will struggle to grow and develop.
Answer:
C) increase the frequency of mutations in all genes
Explanation:
François Jacob and Jacques Monod carried out a series of experiments during their studies on the regulation of gene expression in <em>E. coli</em>. They exposed the <em>E. coli</em> cells with ultraviolet light or X-rays to allow mutations in all the genes to investigate the nature of enzyme synthesis in <em>E. coli</em>. They observed that some enzymes are synthesized continuously. They called those enzymes the constitutive enzymes. On the other hand, some enzymes were synthesized only when required by the cell.
Their further experiments included selective mutation of specific regulatory genes to observe the effect on the expression of other genes.
meiosis is about making kids and are alsways different (except for twins)
mitosis is about your body cells and is always the same.
