Answer:
The shape allows the enzyme to bind with a specific substrate.
Explanation:
Substrates and enzymes are like puzzle pieces. They need to be specific shapes to fit together. When they fit together, they do their job wonderfully. If they are pushed together without being the correct shape, they could be damaged.
The answer would be A packing becomes less tight. The double bounds create kinks in the chain making it harder for the chains to back tightly
Answer:
The correct answer is d the positive feed back reduces change in the the system
Explanation:
In an biochemical reaction when the released product stimulate the release and activation of the same product and act together to exibit their biological function, then this type of regulation is called positive feedback.
The positive feed back mechanism leads to increased change in the system that"s why it is named so.
For example during blood clotting platelets molecules are released to form clots to stop bleeding. one activated platelet can stimulates the activity of other platelets which then join together to form a group for generating further blood clots.
Answer:
The variation might occur in the population that leads to the evolution of the species. This variation may occur due to natural selection, mutation or recombination.
The variation might change the genotype and allelic frequency of the population and might also change the phenotype of the individual in the population. The breeding adults of the left mouthed in 1981, 1987 and 1990 shows variation and was equally opposite phenotype which is more common in the population.
From experiments that scientists did with bacteria and viruses
