Answer:
Because mitosis takes place throughout your lifetime and in multiple organs, it occurs more often than meiosis, which is limited to the reproductive organs during gamete formation.
Explanation:
Proteins (enzymes) have different levels of structure: primary, secondary, tertiary, and sometimes quaternary. In 2nd and 3rd, they form bonds within their protein components, hence their amino acids bend and loop to form bonds with amino acids on other areas of the protein. These links can be hydrogen bonds, sulfide bonds, etc. Temperatures above optimal can break these linkages, rendering the enzyme inactive or unable to catalyze the reaction(s).
Answer:
Convent bonding of cross linking constrain polymer chains from relative movements. the degree of cross linking will correlate with the stiffness of the polymer. highly cross-linked polymers will also have a high resistance to creep as the chains cannot move into new positions.

Answer:
whether these DNA tests can tell us much about an individual newborn's destiny, they are already a useful research tool that is providing new insights into how genes and environments interact, new avenues for understanding how mental illnesses (and other illnesses) develop and new pathways to explore potential ...

Answer: alternating dark and light bandsof protein filaments
Skeletal muscle fibers contain striations that can be described as alternating dark and light bands of protein filaments. Actin, tropomyosin, and troponin are among the protein filaments. The dark bands are the so-called A bands. Alternating light bands are referred to as I bands.
