Mock ACP MMQs (Honors)

Prokaryotic cells divide through asexual reproduction. What is an advantage of asexual reproduction?

• Increases the chance of survival in a stable environment

• Increases the chance of survival in a changing environment

• Leads to a more genetic variation in the offspring

• Leads to more genetic variation in the parent cells

What are examples of active transport where energy is required? Select TWO correct answers.

• facilitated diffusion

• osmosis

• sodium/potassium pump

• diffusion

• endocytosis

Fill in the chart below using the following words: glucose, sunlight, ATP, CO2, H2O, O2

A diagram of the cell cycle is shown. A cancer treatment drug stops cancer cells from dividing after the G2 checkpoint. During which stage is this drug most effective in the cell cycle?

• Gap 1 (G1)

• Synthesis (S)

• Gap 2 (G2)

• Mitosis (M)

A DNA strand is composed 30% Thymine and 20% Guanine. What are the expected percentages of Adenine and Cytosine?

Circle which three organelles that plant cells and animal cells have in common.

Cell differentiation occurs when:

• DNA is deleted during the cell cycle

• mutations develop in the DNA of an organism

• specific genes in DNA are activated by environmental factors

• different types of cells in the same organism contain different DNA

Some bacteria are able to digest milk because they have genes that code for proteins to help break down the sugar and lactose in milk. To regulate the production of these enzymes in prokaryotes, the promoter and operator work as switches that activate or deactivate genes on the lac operon. This occurs during —

• reproduction

• transcription

• replication

• translation

To maintain homeostasis, cells absorb and excrete substances through the phospholipid bilayer of the cell membrane. In which process do cells use vesicles to excrete substances?

• facilitated diffusion

• endocytosis

• exocytosis

• simple diffusion

On the hemoglobin gene, glutamic acid is sometimes replaced by valine. What is the significance of this change?

• A point mutation causes sickle cell anemia, which results in disfigured red blood cells

• A chromosomal mutation causes Klinefelter’s syndrome, which results in reduced fertility.

• A translocation mutation causes chronic myeloid leukemia, which affects blood circulation

• A deletion mutation causes muscular dystrophy, which results in muscle degeneration and death
