Answer:

  • Phosphate group head
  • Two fatty acid tails

Explanation:

A phospholipid is made up of a phosphate group head and two fatty acid tails. They are connected by a molecule of glycerol.

To form cell membranes, phospholipids line up with their hydrophilic (water loving) heads on the outside of the cell and their hydrophobic (water hating) tails inside.

A second layer of phospholipids forms with the heads facing inside the cell and tails facing away. This forms a double layer - with the phosphate group heads on the outside, and fatty acid tails on the inside. This double layer, called a lipid bilayer, forms the cell membrane.

4. Evaporative cooling can be defined as the process of removal of the latent heat from a surface by the evaporation the evaporation of a liquid from there, which results in the reduction of the temperatures. This technique is used for cooling the homes in the dry and hot areas, such as South Carolina. The dry and hot surrounding there makes it easier for the water to evaporate when it passes through the evaporative coolers, making the surrounding air cooler.

Hence, the given statement is true.

5. When the outside temperature is as high as 83 degree Celsius, while the relative humidity is 66%, , it is likely that the sweating will take place, and the water will be evaporated from the skin, making a person feel cooler.
