The cells in red bone marrow that produce blood platelets are called megakaryocytes, which can be
tia_tia [17]

Answer:

Limits platelets population.

Explanation:

The result of this  modified cell cycle would be the presence of limited population of this cell because no mitosis occurs in these cells. Mitosis is a type of cell division that increases population of the cells. These megakaryocytes are changed into platelets by releasing protoplatelets that break up into a number of smaller and functional platelets. These platelets skip mitosis and cytokinesis process which limits their population in the body.

A population of walleye increased from 1200 to 3700 from 2004 to 2006 what is the Growth rate?
Varvara68 [4.7K]

Answer:

The growth rate is 1250 per year.

Explanation:

  • First of all, lets consider the population number in both years;

The initial population is 1200, and

Final population is 3700.

  • Total increased population is (3700- 1200) = 2500

So 2500 population were increased in (2006 - 2004)= 2 years.

  • To find the annual growth rate: (Increased population/ time span in years)= 2500/2= 1250 per year.
  • Hence 1250 population was added per year in walleye from 2004 to 2006.

Somatic is to autonomic as ______ is to ______.
Colt1911 [192]
<span>Somatic is to autonomic as voluntary is to involuntary.
The autonomic nervous system or visceral nervous system (also called vegetative nervous system) is the part of the nervous system responsible for functions not subject to voluntary control (like heart rate, breath...).

The somatic nervous system is the part of the peripheral nervous system that controls the movements and position of the body and allows to perceive through the skin various sensations (touch, heat, pain) and discover through the other sense organs the surrounding environment (like vision, hearing, olfaction...).

Both of the nervous systems consists of sensory neurons and motor neurons.

About rest and excitation, they are controlled by the two parts of the autonomic nervous system (sympathetic an parasympathetic).</span>
