Answer: Option A
Explanation:
Birds attach the bur of the plant which helps in the pollination. The birds sit on the plant and the burs of the plant gets attached in the legs of the birds which is transferred from one place to another.
Seeds at a different place will help in reproduction and growth of the plants. In this case the birds are carrier of the burs.
This is how the birds help in the reproduction of the plants by becoming the messenger.
The third phosphodiester bond of ATP is broken mostly. The rest of the molecule is called Adenosine Diphosphate or ADP.
<h3><u>Explanation:</u></h3>
For knowing the answer, we need to know the structure of ATP first. ATP or the Adenosine Triphosphate is also called the energy currency of living cell. It has two components -
A. Adenosine which is actually an Adenine nitrogen base attached with a ribose sugar molecule.
B. Phosphate molecules.
The structure of Adenosine Triphosphate is a ribose sugar which is attached with one adenine molecule with which one phosphate ion is attached and the rest of the phosphate ions are attached with the phosphate one after the other.
Ribose - Adenine - Phosphate - Phosphate ~ Phosphate.
The last phosphodiester bond between the two phosphates is the most energetic bond containing maximum of the energy. This bond is broken during the metabolic processes to supply energy to the processes.
