Answer:
1. It is called the thermosphere because temperatures can reach up to 1,500 degrees Celsius (2,732 degrees Fahrenheit). However, despite the high temperatures, the pressure is very low, so satellites don't suffer heat damage.
2. The physical and biological changes that confirm climate warming include the rate of retreat in glaciers around the world, the intensification of rainfall events, changes in the timing of the leafing out of plants and the arrival of spring migrant birds, and the shifting of the range of some species.
3. Yet history is not the only reason why flood-prone locations are overpopulated. For one thing, rising sea levels and a changing climate are putting more cities' residents at risk. And what's more, new homes are still being built in flood-prone areas around the world.
4. A natural disaster is the consequence of the combination of a natural hazard (a physical event e.g. volcanic eruption, earthquake, landslide) and human activities. ... A natural hazard will hence never result in a natural disaster in areas without vulnerability, e.g. strong earthquakes in uninhabited areas.
5.
Carbon dioxide dissolve readily in sea water hence makes it high in carbonic acid concentration. The fresh water will dilute the concentration of carbonic acid thus preventing the crab from being exposed to high concentrations which can dissolve its shell.

Explanation:
The biological Edema refers to the swelling of any portion of the body which could be small or large. The swelling is caused when the fluid from the blood vessel is leaked to the nearby tissue which causes the redness also.
Edema is assessed by measuring the depth of the pit formed by swelling in which 4+ edema shows that the edema is very deep pitted (6-8mm) which could last for 2-5 minutes.
Thus, option-D is the correct answer.
