<h2>During Calvin Benson cycle or dark reaction - Option C</h2>
Carbon dioxide from the air is used to produce glucose and other compounds.This happens during the Calvin-Benson cycle, or dark reaction because the reason is the Calvin cycle is also called as dark reaction or the Benson-Calvin cycle.
This cycle is the assemblage of biochemical reactions which undergoes in chloroplasts during the phenomena of photosynthesis. The cycle is light-independent because it undergoes subsequent the energy has been achieved from sunlight. In dark reaction carbon dioxide and hydrogen are combined to produce glucose and oxygen as a by-product.

Answer:
The correct option is B. It helps the fertilized egg attach to the uterine wall.
Explanation:
The uterus contains some of the strongest muscles of the body. It is made up of three thick layers:
1. The perimetrium 2. the myometrium and 3. the endometrium.
The walls of the endometrium thicken during ovulation and also pregnancy.
When fertilization occurs, the walls of the uterus help the eggs to stick to the uterine walls. The endometrium thickens more and more to protect the egg and to nourish it..
That's how the food chain works. There isn't much to it.
