ANSWERS
Passive Transport - ANSWER-Requires energy?
NO
Low to high or High to low?
High to Low
Examples
Diffusion & osmosis
Active Transport - ANSWER-Requires energy?
YES
Low to high or High to low?
Low to high
Examples
Exocytosis & endocytosis
When does the duplication of DNA occur? - ANSWER-S phase during Interphase
What is a cell doing during the GI and G2 periods? - ANSWER-G1: cell growth; G2:
cell prepares to divide
What happens during cytokinesis? - ANSWER-The cytoplasm divides
If the cell cycle is controlled by enzymes, what might result if the genes that control
the production of these enzymes are damaged? - ANSWER-The cell could not
control its growth rate and would continue to divide - leads to cancer
Interphase: - ANSWER-DNA replication
Meiosis - ANSWER-Type of Reproduction
Sexual
Chromosome number of parent cell

When does DNA replication take place?
Interphase
mRNA - ANSWER-carries message from DNA
rRNA - ANSWER-makes up the ribosome
tRNA - ANSWER-transfers amino acids to the ribosome
What is a mutation? - ANSWER-Change in genetic sequence
What is the end result of DNA replication? - ANSWER-Two new molecules - made
