meiosis
b)
diffusion
c)
feedback
d)
respiration
2.
One purpose of ATP molecules in plants and animals?

to increase rate of diffusion across cell membranes
b)
to decrease rate of chemical reactions
c)
to store energy for cellular processes
d)
to pass genetic traits to offspring

insulin is constantly released to prevent low glucose levels in blood
c)
insulin causes addition of large amounts of glucose to blood
d)
high levels of insulin decrease blood glucose levels.
