is the regrowth of lost tissues or organs in response to injury. This is in contrast to wound healing, which involves closing up the injury site with a scar. Some tissues such as skin and large organs including the liver regrow quite readily, while others have been thought to have little or no capacity for regeneration. However ongoing research, particularly in the heart and lungs, suggests that there is hope for a variety of tissues and organs to eventually become regeneration-capable

Answers

Carbon dioxide concentrations in soil are higher than in the atmosphere because of respiration of the plants, their roots. Also, CO2 is inhigherr concentration because of the decomposition of organic matter. Decomposition of organic matter produce more CO2 because of increased microbial activity. CO2 concentrations can change as a result of temperature change or different soil structure. Composition of air in soil and atmosphere of CO2 is
Soil Air: 0.25% Atmosphere: 0.04%.

Do nerve cells, blood cells, and skin cells all have the same DNA? Explain Reasoning. Please help! :)

Answers

The DNA between nerve cells, blood cells, and skin cells would be because all of the cells in our bodies start from a single fertilized egg.  As cells divide and grow, different genes are expressed, resulting in different cell types. Those cells then produce a variety of proteins specific to the cells they form resulting in most of our chemistry.

he _____ is the division of the autonomic nervous system associated with rest, repair, and energy storage. a. parasympathetic nervous system b. sympathetic nervous system c. somatic nervous system d. endocrine system

Answers

Answer: Option A) parasympathetic nervous system

Explanation:

The autonomic nervous system consists of two parts namely

- the sympathetic nervous system SNS, and

- the parasympathetic nervous system PNS

The PNS stimulates the same organs as SNS, but its action is opposite to SNS.

And it acts to return the body to a normal state, thus it is associated with actions such as:

- slowing heart beat

- dilates arteries,

- lowering blood pressure

- stimulating saliva secretion etc

All these actions of the PNS bring about rest, repair, and energy storage.

Suggest a reason why the veins of a bodybuilder "pop out" more than a person who does not lift weights. why don't we see arteries "pop out"? 4. why do you think arteries, veins and nerves always travel together? provide an example that illustrates your reasoning.

Answers

The veins of bodybuilder pop out more than a person who does not lift weight because of bodybuilders lifts a weight more often such that they put an excessive amount of pressure on their veins where most people don't. 
Varicose arteries they do not exist because not only that they are located deeper in the skin than veins but because they are also equipped which help them to handle blood with higher pressure.
Nerves, veins, and arteries travel together because nerves require the constant blood supply to function as they are supposed to and makes it essential that they travel along with nerves and arteries that can give them blood they require.
