Answer: Edema
Explanation:
The swelling that is caused as the result of inflammation is known as Edema. Just after an injury takes place the traumatized area becomes red, painful and warm. It also starts to swell.
This swelled area is also known as Edema which is caused due to acute response of acute inflammation.
This response is trigerred by the injured tissues. When the body starts healing then, change in blood flow takes place and swelling is also cured.
But sometimes it is so acute that it restricts the normal blood flow and movement of the affected area.

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.
