The correct option for this question is as follows:
a) they are made of many cells
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.

Answer:
<u>the forces of attraction are weak</u>
Explanation:
Particles are held together by forces of attraction between molecules e.g., covalent, van der waals and hydrogen bonds. Such type of forces are easily denatured by slight increase in temperature. The solid nature of the compound melts to liquid form. The size of the molecule determines the amount of intermolecular forces available. Smaller molecules have fewer intermolecular forces compared to larger ones thus the melting point is low. Larger molecules have more intermolecular forces that require more energy to break.
