Answer:
4. The kinetics for the enzymatic processes of microorganisms responsible for decomposition are slowed.
Explanation:
Generally most enzymes work best at optimum temperature of 35-40 degree centigrade, This is because enzymes are proteins, and proteins are sensitive to temperature.
Therefore at low temperature of refrigeration below -18 degree, enzymatic processes of microorganisms need for biochemical activities, oxidative activities and growth are slowdown(thus microorganism population is reduced) . Microorganisms are inactive. Therefore the rate of food decomposition is slowed down,which prolonged nutritional value of the food.
The more dominant trait or allele. Eye color is a polygenic trait.
Answer:
p53 gene is an important gene that regulates the proper functioning of the cell. This gene plays an important role in the cell cycle progression and acts as genome guardian.
Any mutation in p53 leads to the formation of the different types of cancer cells. The p53 gene is activated by teh phosphorylation at the particular sites. High levels of phosphorylated p53 in the cell indicates that the cells DNA is highly damaged and mutated.
Answer:
When we engage in physical exercises and we sweat the body tries to return to its optimal temperature, as sweat evaporates from the skin, heat is removed from the body, but the body also loses body fluids, therefore one needs to take lot of fluids during exercise as this will help replace the fluid that is lost during sweat.
