I think it’s E since carrying capacity varies depending on the environment the organism is in.
<u>Stem cell </u>research has the potential to significantly impact the development of disease-modifying treatments for Parkinson’s disease with considerable progress made in creating dopamine-progressing cells.
Explanation:
Parkinson’s disease, a neurodegenerative disease, leads to reduction of dopamine (a neurochemical messenger which carries messages involving thinking and body movements to brain) in the body because the disease will target and kill dopamine-producing nerve cells (neurons). This leads to loss of movement and thinking abilities which are activated by dopamine.
Stem cells research is done to study about the prospects of stem cells in stem cell therapy for Parkinson’s patients as a viable source of new dopamine nerve cells. Research has been involved in growing stem cells to replace or regenerate dopamine-producing nerve cells by using embryonic stem cells or induced pluripotent stem cells as a treatment modality in Parkinson’s disease.
Hyponatremia is a condition where the concentration of sodium is abnormally low in the body. Sodium acts as an electrolyte that helps in maintaining the amount of water in the body.
Extremely low amount of sodium in the body leads to weakness, headache, etc. During periods of intense activity body releases vasopressin hormone that helps body to retain water. Endurance athletes become vulnerable to developing hyponatremia because these athletes during water during strenuous exercises. This makes the concentration of sodium low in the body by diluting it with more water.This may lead to hyponatremia.
