HELP PLEASE Based on the cell theory, which of the following is true? (5 points)

All living and nonliving things are made of cells.
All cells are too small to be seen with the human eye.
Small organisms have smaller cells than large organisms.
Large organisms have more cells than small organisms.

All cells are too small to be seen.-true. ( of course they are larger if u see them with a microscope)

All living things are made of cells.- true

Small organisms have more cells than large organisms.-true

Large organisms have larger cells than small organisms- false

Explanation:

what have scientists found to be the most efficient and effective way to insert new sequences into an individual? a-scientists have created genetically altered foods that release dna during digestion. b-scientists use viruses to insert specific gene sequences. c-scientists irradiate genes so that they can be absorbed through the skin.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
