Answer:
The correct answer is - 10³ seconds.
Explanation:
The nerve impulse is an electrical signal in which fluctuation in membrane potential occurs and forms an electrical signal that takes place that travels along the axon to the synapses.
Suppose a nerve impulse starts only when the first impulse ends according to the question so the one impulse last for the 10⁻³ second or 1 ms.
Thus, the nerve impulse fires per second will be equal to impulse generate in each second which is 1/10⁻³ = 10³.
Thus, the correct answer is - 10³ impulse per second or 1000 impulse per second.

Answer:
According to what is observed in point A of the graph, referring to the population of beetles, there is no competition for resources.
Explanation:
The graph shows that a controlled population of beetles, where other individuals do not enter or leave, experiences <u>progressive growth over time</u>. This is because the population has sufficient resources to guarantee their development, the birth rate exceeds that of mortality and there is no competition for these resources.
The adequate amount of resources allows that, at point A, the carrying capacity has not been reached, a consequence of no competition among members of the same species, which ensures that the net population growth rate is maintained or even increase.

A total of <u>20</u> amino acids compose the majority of protein in living things and nine are <u>essential</u> to human.
- All living organisms, from bacteria to people, depend on amino acids for survival.
- The same 20 types of amino acids are present in all living things.
- Only 21 amino acids are required by the human body to create all the proteins required for growth and function.
- Your body can create thousands of different types of proteins with only the same 21 amino acids because they can be ordered in a wide variety of ways.
- The body is unable to produce essential amino acids. They must therefore originate from food.
- Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine are the nine essential amino acids.
