The correct answer is option d, that is, neurotransmitters.
A neurotransmitter refers to a chemical component, which is discharged at the terminal of a nerve fiber by the introduction of a nerve impulse, and by diffusing across the junction or synapse. It helps in the transfer of the impulse to another muscle fiber, nerve fiber, or some other composition. Acetylcholine is a kind of neurotransmitter, that is, used by neurons in the CNS and the PNS in the control of activities ranging from heart rate and muscle contraction to digestion and memory.
Answer: James Watson and Francis Crick
Explanation:
In 1953 James Watson and Francis Crick are responsible for determining the structure of DNA. James and Watson proposed that the DNA is made up of a double polynucleotide chains that are twisted around each other to forming a helical structure. The two DNA chains runs anti-parallel in opposite direction to each other. Like the structure of the ladder.
The answer is James Watson and Francis Crick
1 bactericidal are solutions used to Kill micro organism by killing the cell walls. while in the other hand bacteriostatic agent is used to inhibit the growth of micro organisms by interfering with their cellular metabolism like replicating their DNA reproduction.
2 bactericidal decreases the number of bacteria in the body while the other does not rather it decreases the growth of it.
Processes that are most important to human life are oxygen, required for cellular respiration, and glucose, a form of sugar that releases energy during cellular respiration.
