Answer 1

Answer:

1.) In biology, cell theory is the historic scientific theory that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all organisms and also the basic unit of reproduction.

Part 2-Hans and Zacharias Jansen, Robert Hooke, Matthias Schleiden, Theodor Schwann, Robert Brown; were all the scientists that contributed to the cell theory.

2.) Prokaryotic and Eukaryotic. Prokaryotic cells lack a nucleus and other membrane-bound organelles.  Eukaryotic cells have a nucleus and other membrane-bound organelles. This allows these cells to have complex functions.

3.) Homeostasis is the state of steady internal, physical, and chemical conditions maintained by living systems. This is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits (homeostatic range).

4.) I can't help you here, sorry.
