Scientists used cells called fibroblasts to study factors that cause nondividing cells in the G0 stage of the cell cycle to reenter the cell cycle and undergo mitosis.


A cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.

The correct answer is : option D.

Explanation:

The given example of the slime mold that flows on a rotten log and the parasitic flatworms and other insects shows no cellular distinction as they lack true partitioning in between their cells of the body. These organisms (insects and parasitic flatworm) have syncytial tissues but lack cell membranes.

All these organisms still follow the rules of cell theory as they are made up of cells and rise from pre-existing cells and all cells of an organism are similar to one other. However, it is not necessary to have a cell membrane and it can be abandoned.

Thus, the correct answer is : option D.

The correct answer is A cell surface receptor molecule becomes activated by binding to a molecular signal.The cell does not return to its normal activities after signal has exerted its effect.

Explanation:

Cell signalling deals  with the binding of sinalling molecule to the receptor present in the surface or interior of the target cell,the binding of signalling molecule activates the receptor,the activated receptor then carry the signal to the interior of the cell, the transmitted signal to cell"s interior activates many protein such as enzymes that carry out the further cellular and physiological processes related to the activity of that cell.

            But after all of these incidents the cell returns to its normal state to carry out another cycle of signalling process.

The shape of normal red blood cells must allow them to easily slide through blood vessels. Red blood cells are shaped similar to to inner tubes so they can slide through the "waterslides" of blood vessels.

Option B.

Sodium cannot enter and cause the membrane to depolarize. The action potential cannot be sent along the axon, so the neuron does not send a signal to the muscles. Thus the muscles are paralyzed

Explanation:

Tetrodotoxin is a neurotoxin that is found in the liver and gonads of Marine organism. it block sodium channels and the consumption of organisms that has it can cause neurological and gastrointestinal disorder. It is produced by some infecting or symbiotic bacteria like Pseudoalteromonas, Pseudomonas, and Vibrio as well as other species found in animals.

Tetrodotoxin stop signals transmission from nerves to muscles by blocking the sodium channels and muscles in contracting for nervous stimulation. This in turn cause rapid weakening and paralysis of the muscles which include that of the respiratory tracts and can result to arrest or death.
