Answer: ionotropic; metabotropic

Explanation:

A receptor can directly open the channel and exerts an ionotropic effect. The ionotropic effect takes place by the help of ionotropic receptors. These receptors are membrane bound receptor proteins which responds by the bonding of the ligand.

Due to ligand binding the channel opens and allows the movement of ions into the cells which helps in either increasing or decreasing the action potential.

The receptors can also bind to the ligand and produce metabotropic effect which means by the second messenger.

Korolek [52]

Evolutionary Theory of Aging describes the view that natural selection has not eliminated many harmful conditions and nonadaptive characteristics in older adults. Natural selection is linked to reproductive fitness, which is present only in the earlier part of adulthood. According to evolutionary theory, possibly if some disease occurred earlier in development, it might have been eliminated many centuries ago.

nadya68 [22]

Answer: function in the synthesis of proteins

Explanation:

Ribonucleic acid or RNA is a kind of essential nucleic acid present in the cells of the living beings. The main function of the RNA is to carry the information present in the coded form in amino acid sequence obtain from the genes to produce protein molecules. The amino acid sequence gets assembled on the ribosome brought about by the messenger RNA (mRNA) each amino acid sequence encodes for a typical protein molecule. A single strand of DNA acts as a blueprint for the synthesis of mRNA which is transcribed from the strand of DNA.

Cytochalasins bind actin and block actin microfilament assembly. Cells treated with cytochalasins will not divide. How do cytoch

7nadin3 [17]

Answer:

The correct answer will be option-A

Explanation:

Cytochalasin is the metabolic product released from the fungus. The cytochalasin acts a toxin to the cell as it inhibits the division of the cell.

Cytochalasin act by inhibiting the cytoplasmic separation during cell division as it blocks the formation of contractile microfilaments. The presence of cytochalasin inhibits the elongation of acing filament as it blocks the addition of the monomer to the growing end of the filament.

Since it prevents the formation of the contractile rings and cytoplasmic separation, therefore, option-A is the correct answer.
