Explain how each of the three types of muscle assist with moving blood around the body.

The muscles in our body have the ability to assist the blood vessels and moving blood around the body to distribute nutrients to the cells. The heart muscles (cardiac) located in the heart pumps blood, the skeletal muscles contracts to allow blood to flow, and the smooth muscles are dominant throughout our body also contracts to permit the blood flow.

enzymes loose their form in both unsuitable ph and temprature.

Explanation:

at very high tempratures enzyme molecules denatures due to high speed movements, at low tempratures enzymes works too slow to be useful enough.

low ph solotions contain lot of H+  and high ph solutions have few H+ , and the number of these H+ ions have polar effects on enzymes.  some Enzymes like pepsin works perfect in acidic environment ( ph=2)  while others might work at  high ph  or average ph( like Trypsin  works well at ph=7).
