Answer:
Generally proteins are denatured at high temperature.Therefore when the egg is hard boiled they are denatured since eggs are protein, the 3-dimensional structure of protein is lost, and it is replaces with tangled meshwork of polypeptide chains .This is because the orderly arrangements of disulphide bonds in proteins are disrupted , which results in the formation of inter chains bonds among disulphide bonds, making the protein molecules to link together.This explains the reason for the 3-D structure disruption and formation of a macro molecule.
However, the addition of reducing agent , breaks the covalent disulphide bonds. While detergent breaks the interchain bonds among the disulphide bonds. (The noncovalent bonds),These combined effects untangled the mesh networks of polypeptides formed, and reduces the hardened nature,
Explanation:
A zygote will not undergo meiosis
in an environmental state that is not favorable for the zygote’s survival i.e.
the chance of the zygote to survive is not certain. Take for example, chlamydomonas
will form a zygote under normal asexual mitotic reproduction in a favorable environmental
condition. However, under unfavorable environmental conditions the organism
also reproduce sexually to form a zygote but will never proceed to meiotic
division because of the unfavorable environmental state.
Answer:
Nucleus
Explanation:
It is enclosed by a nuclear membrane perforated by numerous pores. It regulates the activities of the rest of the cell. It contains chromosomes which carry the hereditary materials. One or more densely staining bodies called nucleoli is present in the nucleus. It is site for synthesis of ribosomes
