- C.
Modern cell theory
- D.
None of the above
Correct Answer
C. Modern cell theoryExplanation
The statement "The cell is the basic unit of all living things" aligns with the modern cell theory. This theory states that cells are the fundamental building blocks of all living organisms and that all living organisms are composed of one or more cells. It also states that cells arise from pre-existing cells through cell division. Mendel's model and the 1st law of genetics are not directly related to the concept of cells being the basic unit of all living things. Therefore, the correct answer is modern cell theory.Rate this question:

- A.
Mitosis
- B.
Meiosis
- C.
Genetics
- D.
Cell theory
Correct Answer
A. MitosisExplanation
Mitosis is the correct answer because it is the process by which paired, duplicated chromosomes are divided into single, identical, unpaired chromosomes. During mitosis, the chromosomes replicate and then separate into two identical sets, each with one copy of each chromosome. This process is essential for the growth, development, and repair of cells in the body. Meiosis, on the other hand, is a different process that involves the division of cells to produce gametes (sperm and eggs) with half the number of chromosomes. Genetics and cell theory are not directly related to the division of chromosomes.Rate this question:
