Answer:
<em>Trichomonas vaginalis</em>
Explanation:
<em>Trichomonas vaginalis</em> is a protozoan parasite that causes Trichomonasis.This STD caused by this one-cell organism, is one of the most common infections transmitted sexually.It usually affects the genitourinary tract of both males and females.
Most males who are infected by this parasite hardly know they are being infected by it. Men are typically asymptomatic. But symptoms such as enlarged prostate gland, urethritis, or epididymitis often present themselves later in males.
A cell membrane pump helps human cells to maintain a relatively constant sodium and potassium concentration.
<u>Option: A</u>
<u>Explanation:</u>
Sodium potassium pump is a plasma membrane protein that utilizes energy ATP — Triphosphate Adenosine turning into ADP — Adenosine Diphosphate to deliver intracellular and extracellular sodium (NA+) and potassium (K+) ions sequentially. The purpose of this entire mechanism is to preserve cell equilibrium.
The extracellular medium has a greater concentration of Na while the K concentration of the intracellular fluid is lower. Proteins trap sodium ions in the cytoplasm and pump them out from the cells to preserve cell stability while preserving concentrations. Within the cells proteins inject potassium ions into the cell.
Answer:
Energy is contained within the pond ecosystem and is transferred within the system.
The answer is definitely the first one, the reasons are: A.) Fertilizer helps plants grow faster and they help the plant produce more.
B. ) Pesticides kill harmful insects that would otherwise ravage the food supply.
C.) The easier it is to farm, more food you can make in a short amount of time. Allowing for higher food production.
