Answer:

see in explaination

Explanation:

Density (D) is a quantity defined as mass (m) per unit volume (v): D = m ÷ v. Since these three quantities are related, you can find one of them if you know the other two. This is more helpful than it sounds because density is often a known quantity that you can look up, assuming you know the composition of the material.

Calculations are straightforward for solid objects, but things get more complicated for liquids, where density changes with temperature, and for gases, for which density is dependent on temperature and pressure.

The subcutaneous layer is mainly made of ___.
Gelneren [198K]

The subcutaneous layer is mainly made of  <u>fat tissue.</u>

One of the three layers of skin is the subcutaneous layer, which lies below the dermis. The deepest layer of the skin is primarily made up of fat. It also contains collagen, blood vessels and nerves. The body's fat creates a layer that protects the organs from damage and acts as insulation against the cold. Additionally, it gives the skin structural support.

The depth of the subcutaneous layer in the body's abdominal region, which frequently has higher percentages of fat, can reach three centimeters. The thickness is determined by the person's overall body fat percentage. Other places, like the eyelids, have a subcutaneous layer that is as thin as 1 millimeter and devoid of fat.

The subcutaneous layer has many functions, including insulation, thermoregulation, shock absorption, structural support, and energy storage.

<h3><u>Explanation;</u></h3>
  • <em><u>The energy from the sun reaches the earth, such that 23 percent of the incoming solar radiation is absorbed by the atmosphere by water vapor, dust and ozone. </u></em>
  • <em><u>48 percent of the solar energy is absorbed by the earth's surface, this translates to 71 percent of the energy which is absorbed by the systems of the Earth.</u></em>
  • <em><u>The remaining 29 percent is reflected back to space by clouds, atmospheric particles etc. </u></em>
