Answer:
The correct option is A
Countercurrent multiplication is the process whereby energy is used to generate an osmotic gradient in which water is reabsorbed from the tubular fluid to produced concentrated urine.
Explanation:
Countercurrent multiplication moves sodium chloride from tubular fluid into interstitial space deep within the kidneys. The concurrent multiplication process build up osmotic gradient interstitial fluid in a single effect. Here, sodium chloride is driven by active transport out of the tubular fluid in the thick ascending limb into the interstitial fluid, which becomes hyperosmotic. This result to water moving passively down its concentration gradient out of the tubular fluid in the descending limb into the interstitial space to a point where it attains a state of equilibrium.
Therefore,the correct option is A, where the ions leaves the ascending limb to make water comes out of descending limb.
Scientists currently monitor underground movements, such as earthquakes and nuclear tests, using seismometers – instruments that measure the motion of those events at the Earth's surface.
Answer:
The options
a.) neutrophils
b.) lymphocytes
c.) basophils
d.) monocytes
The CORRECT ANSWER IS a.)
a.) neutrophils
Explanation:
Neutrophils are grouped as granulocytes (they possesses clearly seen cytoplasmic granules). It functions as the body's bacteria killers, and their numbers rises at a swift rate in times of acute bacterial infections. Neutrophils are active phagocytes; they are particularly partial to feed on bacteria. It make up around 40 percent to 60 percent of the white blood cells in the body, and its the first cells produced by the body as a response to a bacterial infection.
The 3 parts that make up an amino acid include the following:
Side Chain - R group
Amino Group or Amine Group
Carboxylic Acid Group
Carboxyl Group.
Answer:
C. Coupled reactions establish an electrochemical gradient across a membrane.
Explanation:
- During cellular respiration in mitochondria, and during photosynthesis in chloroplasts, the electron transport chain requires a proton gradient to pump protons across the membrane by active transport.
- Protons flow back across the membrane by facilitated diffusion through ATP synthase, which utilizes them to phosphorylate ADP to ATP.
- This process of ATP synthesis by harnessing the elctrochemicaal gradient geenrated by the diffusion of protons across the biological membrane through ATP synthase is called chemiosmosis.
