Bones _____. Make blood cells are controlled by smooth muscles are part of the autonomic nervous system are connected to muscles
Alenkinab [10]

Answer:

make blood cells

Explanation:

<u>The red blood cells are made from the bone marrow of bones. </u>

<em>Smooth muscles form organs like the bladder and the stomach and allow them to change shape in order to perform their respective functions. Smooth muscles have nothing to do with bones.</em>

<em>The autonomic nervous system controls the functions of the body such as digestions, arousal, etc. It is a system of nerves, not bones.</em>

<em>Tendons connect muscles to bones, not synapses.</em>

Hence, the correct option is the bones make blood cells.

What are two ways scientists get information about the evolutionary history of a species
Serggg [28]

levacccp [35]

Answer: Hypothalamus

The brain coordinates the physical changes that occur during puberty and the hypothalamus plays an especially important role in this process.

- gonads (ovaries and testes), responsible for producing many of the sex hormones and hence, development of sexual characterictics

- thyroid, responsible for producing thyroxine, responsible for body metabolism and development.

Thus, hypothalamus plays important role in puberty
