Answer: Natural selection is the driving force to explain the mechanisms of evolution.
Explanation:
◼In a given population Organisms usually produce more offspring than what the environment can support.
◼ VARIATION, is driving force for the manifestation of sustainable inheritable characteristics from parents in a given population.
◼ Organisms, who acquired certain characteristics from variation; tend to survive than others, and therefore pass these inheritable characteristics to their offspring.
◼There is competition for the available resources among the offspring which leads to a stable population in size after a period of time.
◼Darwin deducted that, variants of best adaptation will be selected for by natural conditions operating in the environment of the population at that particular period (natural selection).Therefore natural selection takes place, and the organisms with best variation will have selective advantage above others. Consequently they have higher survival rates compare to others in the population.
This is survival of the fittest by natural selection
, this is the second conclusion of Darwin theory.
Answer:
yeah but they develop slowly for a couple of minutes like 20mins - 30mins
The order in which the amino-acids are placed within the polypeptide determines the tertiary structure and therefore the function of the given protein. Amino acids have different functional groups like methyl(CH3), phenyl(C6H5). Those functional groups can interact with molecules like glucose determining reactions, the proteins that catalyze reactions are called enzymes. Other functional groups of amino acids can be the sulfate groups. For example, insulin has 2 polypeptide chains(Chain A has 21 amino acids, and chain B, 30). Between the two polypeptide chains, 2 disulfide bonds form altering its shape.
