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.

Environmental microbiology is the science in charge of the study of microorganisms, small living things known as microbes. Study organisms that are only visible through a microscope, such as prokaryotic and simple eukaryotic organisms.
Metagenomics is the study of a collection of genetic material from a mixed community of organisms. Metagenomics usually refers to the study of microbial communities. It is generally used when studying microbial communities in which one microorganism cannot be separated from another.
