Answer:
The correct answer is 2.) 1 , 2
Mitosis is a type of cell division in which single parent cell divides into two daughter cells with equal number of chromosomes as in the parent cell.
It occurs in somatic cells of the body for growth and repair of the tissue.
It maintains the chromosomal number between parent and daughter cells and it is the reason that it is also called as equational division.
Answer:
D. DDT
Explanation:
DDT is highly persistent in the environment means that it break down very slowly in the environment. The half-life for DDT is from 2 to 15 years. Half-life is the time needed for the degradation of half of the compound. Persistent bio-accumulative toxic substances (PBTs) are chemicals that break down slowly in the environment and its accumulation in living organisms are toxic. Some PBTs are dispersed through air currents while some uses other environmental pathways, resulting in contamination of regions far from their points of origin.
Answer:
liquid- enzymes
protein- fat
carbohydrate- saccharides
nuclei acid- dna or deoxyribonucleic acid
C. Lactic acid fermentation
<h2>cAMP and glucose mobilization</h2>
Explanation:
It would maintain high cAMP level and elevate glucose mobilization
- Phosphodiesterase is an effector enzyme which degrades secondary messenger cAMP(cyclic adenosine monophosphate)
- Here in this case an inhibitor is inhibiting the phosphodiesterase therefore cAMP level will increase
- As cAMP level rise it activates a protein called protein kinase A which phosphorylates phosphorylase kinase and activates it
- Phosphorylase kinase becomes active that phosphorylates glycogen phosphorylase and makes it active,glycogen phosphorylase catalyse breakdown of glycogen(in liver and muscle cells)
- In liver cells breakdown of glycogen occurs and glucose 1 phosphate gets converted into glucose and supplied to whole body through blood
