Mock Review Part 2

An animal encounters danger, and adrenaline production is signaled. Which body systems are involved?

• The nervous system signals the endocrine system to release adrenaline into the circulatory system.

• The muscular system releases adrenaline directly into the bloodstream.

• The immune system detects danger and signals the digestive system.

• The respiratory system releases adrenaline to increase heart rate.

• Decreased atmospheric carbon dioxide

• Carbon dioxide concentrations increase

• Lower temperatures due to reduced sunlight

A checkpoint gene prevents damaged cells from continuing through the cell cycle by stopping progression when damage is detected. What would happen if a mutation occurred in this gene?

• The cell cycle would continue unregulated.

• The cell would stop functioning completely.

• The mutation would have no effect on cell division.

• The cell cycle would speed up, but remain controlled.

The formula for photosynthesis is: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂. How is energy transferred during photosynthesis?

• Light energy is converted to chemical energy in glucose, which is later converted into ATP.

• Energy is lost as heat during the reaction.

• Light energy is directly converted into oxygen.

• The reaction releases more energy than it absorbs.

If a plant hormone is added to water, which part of the plant would absorb it, and how would it be transported?

• The leaves absorb it and transport it through the phloem.

• The stem absorbs it and moves it through the phloem.

• The roots absorb it and transport it through the xylem.

• The roots absorb it and move it through the phloem.

Why are cell cycle checkpoints important?

• They allow cells to divide uncontrollably.

• They help regulate the cycle and prevent damaged cells from dividing.

• They initiate mutations to improve cell function.

• They eliminate all old cells from the body.

The formula for photosynthesis is: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂. How is matter conserved in photosynthesis?

• The number of carbon, hydrogen, and oxygen atoms remains the same.

• Energy is created during the process.

• The number of atoms decreases in the final product.

• Oxygen is completely removed from the reaction.

• Translocation

• Substitution

• Insertion

Which of the following is true regarding point mutations?

• The length of the DNA changes.

• They cause a frameshift in the DNA sequence.

• The reading frame of the DNA sequence will move to a different location

• They do not cause a frameshift in the DNA sequence
