What are the three main points of the cell theory?

1. All living things are made up of cells.

Example: Humans are made of cells, animals are made of cells, plants are made of cells...

2. Cells are the smallest units. Indeed, it is the smallest unit of life and it is as fundamental for biology as the atom is in chemistry

3. All cells come from preexisting cells through the process of cell division.

So, cells come from previous cells that went through a process of cell division, and during that division a new cell was created.

Hope this helps :)

i think it would be b the increase in body temp

since you have not provided the options here i   am going to give you general overview about hormone.hormone are actually the part of endocrine system in our body and produced by the endocrine glands. the hormones act like a chemical messenger   within human body. once produce by the glands they   travel through the blood stream and reach at specific or target tissue and organs   which result in control of our body function. the hormones are specific in their work and work on only the targeted tissue or organ   . with the of hormone endocrine system regulate the heart rate , metabolism, our mood and   growth as well as the development and even the sleeping cycle etc. they actually are the messenger for body cell and organs .
