Which explanation about cellular reproduction is best supported by the models?
a
Meiosis and mitosis both produce daughter cells with fewer chromosomes than the parent cells.
b
Binary fission and mitosis both produce daughter cells that are identical to the parent cells
c
Meiosis and binary fission both include the process of crossing over during cellular replication and two divisions.
d
Mitosis and meiosis both produce diploid and haploid gametes during cellular replication.
Question 17
Ultraviolet radiation causes mutations in the DNA of skin cells that have been exposed to the Sun. Will such mutations have any effect on future offspring?
a
yes, because skin cells play an important role in reproduction
b
yes, because DNA is passed on from parent to offspring
c
no, because the changes have no effect on the gametes of the parents
d
no, because offspring are immune to changes in parental DNA
Question 18
The diffusion of WATER across a selectively permeable membrane is called
a
osmosis.
b
active transport.
c
facilitated diffusion.
d
endo-aqua thermogenesis.
Question 19
How do active transport and facilitated diffusion differ?
a
one uses help from proteins and the other does not
b
one requires energy and the other does not
c
active transport moves molecules against a concentration gradient and facilitated diffusion does not
d
both b & c
