After Ken's funeral, his wife Helen decided to offer his collection of CDs to members of his local Jazz Club.As there were so many CDs, it was not possible for all of them to take some home, so 60% of the collection was put into a box from which members could take the ones they wanted. By the end of the meeting half of these had been taken.A week later, a further 30% of the original collection was added to the box. During this meeting three quarters of the CDs in the box were taken.At the third meeting, the rest of the collection was added to the box.

Question 10

The 'Healthy Options' shop serves a range of organic foods. The manager has employed a new assistant and has asked her to prepare 30kg of their 'nut and raisin' mix, which should consist of 30% peanuts, 20% hazelnuts and 50% raisins. The assistant has, however, made a mix using 10kg of each. The manager told her to add the minimum amount of extra ingredients to make the proportions right.What should be the mass of the final mix (to the nearest 1kg if necessary)?

Accepted Answer

30kg

Answer

33kg

Answer

40kg

Answer

50kg

Question 11

Experiment: Researchers injected insulin into a fasting rabbit and measured its blood glucose levels every 30 minutes for 4 hours.Observation: Blood glucose dropped sharply in the first 2 hours, then stabilized at a low level.Question: What does this experiment suggest about insulin's role?

Accepted Answer

Insulin lowers blood glucose by promoting its uptake.

Answer

Insulin raises glucose levels during fasting.

Answer

Insulin inhibits all glucose activity in blood.

Answer

Insulin has no effect on fasting animals.

Question 12

Experiment: To examine phototropism, seedlings were grown with a unidirectional light source. One set had light from above; another from the side.Observation: Seedlings with side light bent toward the light source, while vertical light resulted in straight growth.Question: What can be concluded?

Accepted Answer

Auxins accumulate on the shaded side, causing cell elongation.

Answer

Light destroys hormones on the light-facing side.

Answer

Plants always grow straight regardless of light direction.

Answer

Light inhibits all types of plant growth.

Question 13

Experiment: A bird species was studied over 10 years in a changing environment. Beak size data was collected annually.Observation: During dry years, birds with thicker beaks had higher survival rates.Question: Which evolutionary concept is illustrated?

Accepted Answer

Natural selection favors traits beneficial to survival.

Answer

Genetic drift led to uniform beak sizes.

Answer

Mutation causes all trait changes.

Answer

Environment has no role in evolution.

Question 14

Experiment: A student compared oxygen bubbles from Elodea (aquatic plant) placed under different light intensities in water.Observation: Bubble rate was highest at moderate light and plateaued at high intensity.Question: What is a valid interpretation?

Accepted Answer

Photosynthesis increases with light intensity but levels off due to limiting factors.

Answer

Oxygen production is directly linked to photosynthesis.

Answer

Higher photosynthesis is always associated with low light intensity.

Answer

Bubbles observed are a result of plant respiration, not photosynthesis.

Question 15

Experiment: Rats were exposed to increasing doses of caffeine, and heart rate was recorded over time.Observation: A consistent rise in heart rate was observed with higher caffeine doses.Question: What is the likely conclusion?

Accepted Answer

Caffeine stimulates the cardiovascular system.

Answer

Caffeine reduces heart rate under stress.

Answer

Caffeine has no biological effects.

Answer

Rats are immune to caffeine.

Question 16

Experiment: Chloroplasts were isolated and exposed to light with and without CO₂. ATP production was measured.Observation: ATP was produced with light even in the absence of CO₂.Question: What does this show?

Accepted Answer

Light reactions occur independently of carbon fixation.

Answer

CO₂ is required for ATP synthesis.

Answer

ATP forms only during the dark phase.

Answer

Photosynthesis stops without CO₂.

Question 17

Experiment: An earthworm was cut into two segments. Only one half regenerated into a complete worm.Observation: The anterior half (head side) showed regeneration.Question: What biological process does this demonstrate?

Accepted Answer

Regeneration is polarity-dependent in organisms.

Answer

All worm segments regenerate equally.

Answer

Posterior parts have more stem cells.

Answer

Earthworms cannot regenerate.

Question 18

Experiment: Lactic acid buildup was tested in athletes post-exercise using blood tests.Observation: High levels of lactic acid were found in those performing anaerobic exercises.Question: What does this confirm?

Accepted Answer

Lactic acid is a byproduct of anaerobic respiration, which occurs when oxygen levels are insufficient.

Answer

Aerobic respiration primarily produces carbon dioxide and water, not lactic acid.

Answer

Exercise, especially anaerobic, increases lactic acid production due to oxygen deficiency.

Answer

Both B and C

Question 19

Experiment: Two identical aquariums with fish were set up. One had aquatic plants, the other didn't. Oxygen levels were tested over 24 hours.Observation: Oxygen remained higher in the plant tank, especially during the day.Question: What does this suggest?

Accepted Answer

Aquatic plants release oxygen via photosynthesis.

Answer

Fish produce more oxygen in isolation.

Answer

Water itself creates oxygen.

Answer

Plants consume all available oxygen.

Question 20

Experiment: To study reflex action, a subject's knee-jerk response was tested after applying pressure to the thigh nerve.Observation: The reflex was immediate and involuntary.Question: Which conclusion is accurate?

Accepted Answer

Reflexes are fast, involuntary responses bypassing the brain.

Answer

All voluntary actions require reflexes.

Answer

Reflex arcs begin in the brain.

Answer

Pressure slows down reflexes.
