Answer:
f. cyanobacteria
Explanation:
Cyanobacteria are a group of photosynthetic bacteria. They have the ability to use water as a source of an electron during the process of photosynthesis. Splitting of water produces molecular oxygen that is released into the surroundings. In this way, cyanobacteria release oxygen gas in the air. The primitive atmosphere of the earth was reducing and did not have oxygen gas. The first photosynthetic organisms that could split water during photosynthesis are supposed to be cyanobacteria. These prokaryotes added oxygen to the atmosphere of the early earth and gradually made it oxidative from reducing.
Answer:
The correct answer will be- true
Explanation:
In Human skeletal system, the point at which the two bones meet is known as the joint which is responsible for the stability of the body and the movement.
The joints can be classified on the basis of their structures and the functions (amount of movement).
On the basis of movement, the bones are classified into
1. Synarthroses (immovable joints)- the joints which do not move like sutures.
2. Amphiarthroses (slight movement)- the joints which slightly moves like symphyses
3. Diarthroses (free movement)- the joints which freely moves like synovial joints.
Thus, true is the correct answer.
