b) they are made of one or more cells
c) they come from the same kind of cell
d) they come from noncellular structures
Answer:
The correct answer is - option b. they are made of one or more cells
Explanation:
The cell theory has three major parts that are; the cell is the basic and physiological unit of the organism, all living organisms are made up of one or more cells, new cells come from the pre-existing cells.
On the basis of the cell theory, we can say that all organisms including the cheetah that is a multicellular organism or paramecium a single-celled organism, are made up of one or more cells.

Ctenophorans have comb-like plate cells for swimming. Platyhelminthes - members are first to have sensory and nervous tissue in the head region.
Answer:
Mitosis
Explanation:
Mitosis is not a source of genetic mutation because it take place mostly in the somatic cells. This is because it does not lead to the production of gametes . In mitosis, the parent cells divide into two daughter cells and each daughter cells are genetically identical to the parent cell because they carry the same number of chromosomes as the parent cell. There is no genetic variation in this.
