Answer:

Muscles pull on joints, which allows us to move. They also assist the body in performing tasks such as chewing and transporting food through the digestive system. Even when we sit absolutely motionless, our muscles are continually moving throughout our bodies.

Answer:

Muscles are attached to bones by tendons and help them to move. When a muscle contracts (bunches up), it gets shorter and so pulls on the bone it is attached to. When a muscle relaxes, it goes back to its normal size. So it helps the body to move by letting us be firm and have the ability to balance and do many things we couldn't without bones.

What situation might develop in a population having some plants whose flowers open at midday and other plants whose flowers open
Kay [80]

Complete question: What situation might develop in a population having some plants whose flowers open at midday and other plants whose flowers open late in the day?

a. Temporal isolation

b. Geographic isolation

c. Behavioral isolation

d. Genetic drift

Answer:

a. Temporal isolation

Explanation:

Temporal isolation is one of several mechanisms of reproductive isolation. Temporal isolation occurs when some organisms of a population exhibit different timing of reproductive maturity. It also occurs when some members of a population reproduce at a different time from the others. This does not allow interbreeding between them.

When plants of a population open flower at a different time of day, cross-pollination would not occur between these plants. This represents temporal isolation.

During the process of oxidative phosphorylation, electrons are exchanged between the molecules, that creates a chemical gradient, which is required for the production of ATP. It is known to produce more ATP called the energy currency of cell that any other cellular respiration. It produces 90% of the total ATP synthesized in the cell.
