Answer:
For the eggs to survive and have a chance of hatching, sea turtles must lay their eggs on sandy beaches. As they are developing, the embryos breathe air through a membrane in the eggs, and so they cannot survive if they are continuously covered with water.
Explanation:
Nitrogen Fixation is the part of the nitrogen cycle that is involved in moving nitrogen from the atmosphere into the soil.
<u>Explanation:</u>
- Nitrogen is said to be an essential one in the atmosphere but even though it exists as inactive in the atmosphere it is converted as usable nitrogen by the cycle.
- The nitrogen cycle is considered to be one of the important factors for the survival of the plants. Nitrogen is not used directly in photosynthesis by the plants whereas it is converted to nitrate by the help of nitrogen-fixing bacteria in the soil.
- Thus the nitrogen fixation process converts nitrogen into ammonium ions and then it is used by the plants.
The movement of organelles within the cell is facilitated by motor proteins.
Motor proteins possess the ability to convert chemical energy into mechanical energy. They are able to move along the surface of suitable substrates. Some examples of motor proteins are helicase, prestin and ATP synthase.
