Answer:
Cancer is basically a disease of uncontrolled cell division. Its development and progression are usually linked to a series of changes in the activity of cell cycle regulators. For example, inhibitors of the cell cycle keep cells from dividing when conditions aren’t right, so too little activity of these inhibitors can promote cancer. Similarly, positive regulators of cell division can lead to cancer if they are too active. In most cases, these changes in activity are due to mutations in the genes that encode cell cycle regulator proteins.
Explanation:
To suppress pain and stress.
Answer: Synaptic gap
A synaptic gap is the space between two neurons where the axon of a sending neuron communicates with the dendrites of a receiving neuron by using chemical messages.
Explanation:
Neurons are joined end to end in a special way, the axon of one neuron forms a junction with the dendrites of the next neuron. However, the two neurons do not touch, but leave a gap called synaptic gap.
Thus, synaptic gap is the answer.
Respond to stimuli is not a characteristic.
