Answer:
Four ways by which drugs can affect the nervous system are as follows:
Drugs like heroin can mimics the chemical structure of the neurotransmitters. They causes the excess activation of neurons in the brains and affect the nervous system.
Some drugs also mimics the neurotransmitter but causes the abnormal messages sent through the brain. Their mimicry of neurotransmitters cannot activate the neuron but causes the interruption and wrong messaging in the nervous system.
Drugs like cocaine causes the stimulation of release of large number of neurotransmitters. This causes the prevention of recycling of brain chemicals and disturbs the neuron communication.
Some drugs causes the inhibition of release of neurotransmitters in the brain. This stops the signalling of the nervous system and interrupts the chemical messages of the body.
Competition of resources, predation or disturbances (man-made and natural)
Apoptosis is the controlled death of cells as a part of an organism's growth. A problem in the cell cycle may worsen and become a malignant tumor, as is the case in cancer. Therefore, apoptosis is helpful in preventing such a situation where the cell's division may become uncontrollable.
