How are chromosomes passed down to offspring in sexually reproducing organisms?(1 point)
Responses
Offspring receive their chromosomes from one or the other parents.
Offspring receive their chromosomes from one or the other parents.
Male offspring receive chromosomes from fathers and female offspring receive them from mothers.
Male offspring receive chromosomes from fathers and female offspring receive them from mothers.
Each parent shares one chromosome from every pair with their offspring so offspring have a complete set.

The best description of the inputs and outputs of mitosis in a multicellular organism is:
**Input: A single cell ready to divide. Output: Two daughter cells that are genetically identical to the parent cell and each other.**
This correctly captures the primary function of mitosis, which is to produce two identical daughter cells from a single parent cell. The other options involve processes like differentiation, which are related but not specific to the outputs of mitosis itself.

The biomolecule that is the same in every cell of an organism is:
**DNA**
All cells in an organism contain the same DNA, which carries the genetic information. While there may be differences in the expression of genes and proteins in different cell types, the DNA itself is consistent across all cells.

The correct response to how mitotic cell division contributes to the growth of multicellular organisms is:
**It increases the number of cells, contributing directly to the size and mass of an organism.**
Mitosis allows for the production of new cells, which increases the overall cell number and contributes to the growth and development of the organism.

The correct response to why mitosis is a longer process in eukaryotes compared to prokaryotes is:
**Checkpoints are designed to detect if there is any damage to DNA.**
Eukaryotic cells have complex regulatory mechanisms, including checkpoints in the cell cycle, which ensure that the cell is ready to proceed with mitosis and that the DNA is undamaged. This complexity contributes to a longer duration of cell division compared to prokaryotes, which typically undergo simpler binary fission without such elaborate checks.

The correct response is:
**sexually.**
Genetic recombination occurs during sexual reproduction when genetic material from two parents is combined, leading to offspring with new genetic combinations. This process enhances genetic diversity within a population.
