The gradual abundance of oxygen (by product of photosynthesis) made it possible for aerobic organisms to grow more and evolve.
Hope that helps!
72 chromatids were present in the present in the primary oocyte during prophase 1 of meiosis.
The primary oocyte contains 72 chromatids during prophase 1 of meiosis as the mature ovum has 18 chromosomes.
The primary oocyte contains 72 chromatids , that means it contains 144 chromosomes. During the first meiotic division, it produces one secondary oocyte and one polar body.
The secondary oocyte has 72 chromatids, which again undergoes second meiotic division and produces mature ovum and second polar body . The mature ovum contains contains 36 chromatids which means it has 18 chromosomes.

Answer:its a covalent bond
Explanation:
Answer: The correct answer is- Solar energy, carbon dioxide, and water.
Light dependent reactions comprise the first phase of photosynthesis (formation of food by green plants and algae in presence of sunlight) process.
This phase occurs in the thylakoid membrane of chloroplast.
During this phase, a green pigment chlorophyll absorbs energy from sunlight (in the presence of carbon dioxide and water) and convert it into chemical energy in the form of ATP and NADPH.
This energy is further utilized in the formation of food (glucose) in the next phase, which is a light independent phase of photosynthesis.
In photosynthesis, oxygen is produced by splitting of water molecule and it is released in the atmosphere.
Thus, solar energy, carbon dioxide, and water is the right answer.
