How does the protein Sic1 regulate the cell cycle?
a. Sic1 is a cyclin that binds to a Cdk to form a cyclin/Cdk complex, which regulates the G1 to S transition. b. Sic1 inhibits an S phase cyclin/CDK complex required for synthesis to occur c. Sic1 binds to a cyclin, to form a complex that regulates the G2 to M transition. d. Sic1 is a growth factor that binds to external receptors and promotes the transition from G1 to S. e. Sic1 is a cyclin that binds to a Cdk to form a cyclin/Cdk complex to regulate the G2 to M transition.

What will be an ideal response?
In your observations of a new rotifer species, you note that diploid females can lay diploid eggs that in turn become diploid female adults. What do you conclude about this behavior?
A. This asexual reproduction by way of budding of a new individual from the parent. B. This is sexual reproduction by way of parthenogenesis. C. This is sexual reproduction because sperm must have been stored in the female for later fertilization of her eggs. D. This is sexual reproduction by way of diploid females laying haploid eggs that hatch into haploid males who in turn produce sperm that fertilizes other haploid eggs. E. This is asexual reproduction by way of parthenogenesis.
