Explain homeostasis and why it’s important to the body
Answer:
Homeostasis regulates your body. When you are too hot, your body produces sweat to cool you down. When you're cold, you muscles shiver to generate warmth. When you have high glucose levels in your blood, your pancreas excretes insulin, and when blood glucose is too low, then it excretes glycogen. Homeostasis basically keeps your body from losing control and it helps you survive.

Explanation:
Answer

Explanation:
Temperature can affect density in certain ways. If the temperature decreases, what effect can that have on the density of a substance?
Liquid water at 25 deg is so rapidly breaking bonds between H2O units and reforming them that extra water molecules get trapped inside the water lattice. This is the reason why liquid water is more dense than solid water.
The bonds in water break more slowly as temperature decreases and the structure tend to trap fewer extra water molecules. At low temperature, more of the water has the same lattice as ice.
Wikipedia, Water Density
It is possible to have liquid water at temperatures well below 0 deg C. Molecules in this supercooled water are free to move. Bonds are made and broken. The long range structure is not perfect but the short range structure of supercooled water is very much like ice. Adding a crystal to supercooled water causes instantaneous ice formation.

Availability of waterTemperatureNatural DisasterWhat is Natural Selection?
Natural selection is a set of characters that deal with the most favorable variations that are promoted by nature.
As predators, the height of legs, fur, the color of the body, size of the body, and size of the beak is not related with environmental changes. It can also be said that these characteristics lead to natural selection depending on the conditions, such characteristics are not linked with environmental changes directly.
Therefore, the three examples of environmental changes that can influence natural selection are the availability of water, temperature, and natural disasters.

Explain the cell theory
Answer:
Explanation:
The cell theory basically just tells you that all living things have more than one cell and that cells are made from other cells. It basically just tells you that cells are our foundation for life, without cells we can't live.
For, example, blood cells. If we didn't have blood cells our body's organs can't get the oxygen and nutrients they need to survive. Without blood cells we could get weak or we could just die instantly.
