During interphase, the cell copies its DNA in preparation for the second stage of meiosis.

Prophase is the first stage of cell division, in which the chromosomes become visible as paired chromatids and the nuclear envelope disappears.

Metaphase is the second stage of cell division in which the chromosomes become attached to the spindle fibers.

Anaphase is the third stage of cell division, in which the chromosomes move away from one another to opposite poles of the spindle.

Telophase is the fourth stage of cell division, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.

Cytokinesis is the division of a cell at the end of mitosis or meiosis that separates the cells into two individual daughter cells.

The peripheral nervous system is involved in _____.
drek231 [11]

The peripheral nervous system is involved in both <u>voluntary and involuntary actions.</u>

Explanation:

The peripheral nervous system (PNS) is the neural system that resides outside the central nervous system (CNS). This contains nerves which in turn connect with the organs of the body like the sensory organs, glands, blood vessels, muscles etc with the central nervous system (CNS).

The PNS is divided into somatic and autonomic nervous systems.

The somatic nervous system contains sensory and motor nerve fibers which send sensory information and controls motor functions respectively. The voluntary movements of skin, skeletal muscles, bones, and joints are controlled by somatic PNS.

The autonomic nervous system composed of sympathetic, parasympathetic and enteric nervous systems controls the involuntary actions of smooth muscles of the internal visceral organs.

The amount of energy at trophic levels one and four in an ecosystem is indicated by the numbers.
nexus9112 [7]

Answer:

1100

Explanation:

There is 10% of total energy in each increasing trophic level.                    10,000 / 10 = 1,000 ,so there are 1,000 units of energy in trophic level 2.

1,000 / 10 = 100, so there are 100 units of energy in trophic level 3.

1,000 + 100 units of combined energy would be 1,100 units of energy.

Hope this helps!
