During upwelling, nutrient-rich water rises to the surface. How would this most likely affect the biotic components of the ecosy
hodyreva [135]

Answer: Increase in species numbers and diversity

Explanation:

Upwelling is an oceanographic phenomena in which the water from the bottom layers of the ocean usually above the seafloor get displaced and reach upto the surface layers with the effect of wind currents. The water carries away along with it the nutrients and the organic matter to the surface layers which allows the efficient growth of plant and planktonic diversity which favors the growth of sea animals like fishes and others. Hence, by this way the species diversity and numbers increases by the process of upwelling.

Which of the following statements about fluid movement is NOT correct?
allochka39001 [22]

Answer:

b. Exchange between the plasma and the intracellular fluid occurs across the cell membrane.

Explanation:

The body fluid can be categorized as extracellular and intracellular fluid. The fluid within cells is called intracellular fluid and the body fluid outside body cells makes the extracellular fluid. The interstitial fluid is the extracellular fluid that is present in the narrow spaces between cells of tissues.

On the other hand, the extracellular fluid present within blood vessels is termed blood plasma. Therefore, plasma and intracellular fluid can exchange material via interstitial fluid only, not directly via the cell membrane. The exchange between interstitial fluid and intracellular fluid occurs across the cell membrane.
