It is the calvin cycle that requires carbon dioxide. It uses the ATP that are produced by the light reaction that takes place in the thylakoid with the help of chlorophyll that traps the sunlight.
Answer:
B. polio—polyhedral shape
Explanation:
A virus is a small parasite which cannot self reproduce. For a virus to produce more viruses, it uses the cell to duplicate itself. Viruses contain RNA or DNA as their genetic material.
Poliovirus is composed of an RNA genetic material and it is responsible for Polio. Polio leads to paralysis and is transmitted through contaminated water or food, or contact with an infected person.
The shape of Poliovirus is formed by polyhedral (many-sided) shell or capsid.
