Cells go through mitosis to replace dead cells and when there is a full healthy layer of skin, it stops. When there is cancer in a cell, it doesn't know when to stop and it keeps going even though there is too much skin. does that make sense?
These chemical processes require energy. The respiration and metabolism require adenosine triphosphate (ATP) which is cellular energy, and the organs get their fuel from the calories we consume. Without this energy, we eventually die
A reflex, or reflex action, is an involuntary and nearly instantaneous movement in response to a stimulus. ... The reflex is then an automatic response to a stimulus that does not receive or need conscious thought.
1.Fossils
2.Location

Scientist use location to study location to see how organisms used their features to cross water or survive in different temperatures.
Answer:
When animal cells are hypotonic means, the cell has absorbed too much water through the membrane. Therefore, the osmotic pressure is very high. Consequently,they deform and could eventually burst.
