The answer is 3468 kcals. Protein and carbohydrates both contain 4 calories per gram, while fat provides 9 calories per gram.
Carbohydrate = 240 gms x 4 = 960 cal Protein = 132 x 4 = 528 cal Fat = 220 x 9 = 1980 cal
Total : 960+528+1980 = 3468 calories
D. It allows a variety of substances to dissolve in and around cells.
Explanation:
The shell of hydration is important to life because it allows a broad range of substances to dissolve in and around the cells.
- The shell of hydration allow for water to dissolve a wide range of substances and disperse them uniformly in it.
- Water serves a solvent capable of dissolving a wide range of substances because it forms a hydration shell round them.
- This allow for materials to be in solution around the cell.
- Diffusion and osmosis can readily now take place.

Troposphere – This is the densest layer and where weather events occur
Stratosphere – This is where the ozone layer is found. Some high altitude aircraft cruise in this layer.
Mesosphere – Temperatures drop with altitude in this layer
Thermosphere – This is where most of the meteorites that enter the earth’s atmosphere burn up. This layer takes up most of the Uv and X-rays from the sun. Most satellites orbiting earth are in this layer
Exosphere – almost akin to space due to the thinness of the layer. Molecules in the layer often escape into space

A ‘pause’ is a transition between the above-mentioned distinct layers. The tropopause, for example, occurs between the troposphere and the stratosphere and the stratopause between the stratosphere and mesosphere and thermopause is found between thermosphere and exosphere.
(3)
A temperature inversion is a rise in temperatures with altitude in a layer in the atmosphere. One layer exhibiting temperature inversion is the stratosphere. This is due to the ozone layer that absorbs UV light. The upper ozone absorbs most of the UV light, than lower ozone, exciting the molecules and making the higher altitudes in the layer to be warmer.

The ozone layer protects life on earth from the high energy UV radiation from the sun. UV is capable of causing double-stranded break on DNA resulting in genetic mutations on organisms. Most of these would be lethal. The Ozone absorbs most of the UV before it reaches earth's surface. Ozone is formed when an oxygen molecule reacts with another oxygen atom to form an O₃. The oxygen atoms are made from the splitting of an oxygen molecule by UV light.
