Microscopic plants called algae grow inside the top layer of sea ice in the Antarctic if enough sunlight reaches that layer of i
MrRa [10]

Answer:

The correct answer is: (A).

Explanation:

  • In the question, it is mentioned that the algae can grow under the conditions of "enough sunlight" and "enough nutrients".
  • Sunlight reaches the algae, by first falling on the surface made up of ice and snow and then refracting from there into the top layer of the ice where the algae grows.
  • However, the capability of both snow and ice to reflect sunlight is far more than that of refracting sunlight.
  • Therefore, the amount of light received by the algae is similar in absence or presence of the layer of snow on the top layer of ice.
  • However, on deposition of snow on the layer of the ice, the weight of the ice increases and it sinks below into sea water.
  • This allows more nutrient rich sea water to percolate into the ice and reach the algae.
  • The algae receive more nutrients from the sea water and hence is capable undergoing better metabolism and growth.
  • Hence, more algae are produced under such a situation.

While taking a walk around the neighborhood, a student walks into a tree branch and cuts their arm. Which explanation BEST descr
DaniilM [7]

Answer:

C

Explanation:

First off, humans are considered animals, and since animal cells don't have chloroplasts, A and D are immediately incorrect. B is incorrect because lysosomes eject enzymes that digest materials in the cell, and to heal skin, you dont need to digest anything/ use enzymes to get rid if materials. That means the answer is C. The nucleus is the control center for the cell, so it tells the cell what to do. The mitochondria creates energy for the cell, and since it takes energy to heal, this answer is correct. (Tip- I find that using process of elimination in biology questions helps a lot.) Good luck!
