Question

1. the image shows damaged cells in the tissue of a multicellular organism being repaired.

which property of mitosis helps in the repair process?
a mitosis produces cells that are larger than the parent cells.
b mitosis produces cells that are identical to the parent cells.
c mitosis produces cells that are weaker than the parent cells.
d mitosis produces cells that are healthier than the parent cells.

1. the diagram shows two parent fire salamanders and three offspring.

based on the diagram, which statement best explains how the offspring inherit their traits?
a the offspring receive genetic traits from the female parent only.
b the offspring inherit identical genetic traits to one of the parents.
c the offspring combine different genetic traits from both parents.
d the offspring develop entirely new traits not present in either parent.

Explanation:

For question 22: Mitosis is a process of cell division where the daughter cells are identical to the parent cell. This property is crucial for repair as the new cells need to function like the damaged ones they replace.
For question 30: In sexual reproduction (which is implied here as there are two parents), offspring inherit genetic traits from both parents. Each parent contributes half of the genetic material, so the offspring combine different traits from both.

Answer:

1. C. Mitosis produces cells that are identical to the parent cells.
2. C. The offspring combine different genetic traits from both parents.
