Stem cells can specialize into any type of cell in the body
The mutagens that result in cancer damage DNA by (b) weakening the DNA strand or interfering with base pairing. This mutagens are called carcinogens, if they cause a damage to <span>a gene that makes a </span>DNA<span> repair protein, it means that a cell will have less ability to repair itself, and ,as a result, this will lead to formation of cancer.</span>
Answer:
limiting factors
Explanation:
The ecological optimum represents the value of the factors within the ecological valence at which the life processes of a species take place best. The upper and lower limits of an ecological valence are its maximum and minimum. Beyond these limits, physiological processes are interrupted and death occurs.
This is because such a mechanism of regulation prevents the simultaneous addition and removal of glucose monomers, preventing unnecessary reactions. Additionally. the two processes occur in the same location in the sell, thus this regulation makes the net process more efficient. When glycogen phosphorylase is phosphorylated its activity increases and vicevarsa.
