Short Response
Human cells are either diploid or haploid. All human
cells with 46 chromosomes are diploid.
Would a human cell with any 23 chromosomes be
haploid? Explain your answer.

Human cells are either diploid or haploid. All human
cells with 46 chromosomes are diploid.
Would a human cell with any 23 chromosomes be
haploid? Explain your answer.
Answer:
No, a haploid cell has one complete set of
chromosomes, which in the case of humans is 23.
Randomly having 23 chromosomes would not be
considered haploid.

For a cell to function efficiently, its surface area must
exceed that of its volume.
Part A Explain how cell division maintains the
relationship between surface area and volume.
Part B How does a stable ratio between surface
area and volume help maintain proper cell
functioning?

Answer:
Part A The smaller the cell, the greater is the ratio of
surface area to volume. Cell division makes one
larger cell into two smaller cells.
Part B By having a stable ratio between surface area
and volume, cells are able to maintain homeostasis
by taking in and getting rid of substances efficiently
through osmosis and diffusion.
