The first class lever is the most common lever in the human body. True/False
Answer:
False
Explanation:
In first-class levers, the position of the fulcrum is between the effort and the load. In these levers such as scissors, if the effort (child) is farther from the fulcrum than the load, a heavy load can be moved. There are few first-class levers in the human body.
One of the examples of such a lever is the head resting on the vertebral column. When the head is raised, the contraction of the posterior neck muscles provides the effort and the fulcrum is formed by the joint between the atlas and the occipital bone. Third class levers are the most common types present in the human body.
They both involve sell and reproduction.
Answer:
The correct answer or fill in would be- but <u>Change and evolve</u> over time.
Explanation:

Steady state theory supports this theory as it also says that universe is expanding but also maintain its density even though it continuously creates stars and galaxies but still look same.
Thus, the correct answer is - but <u>Change and evolve</u> over time.
