Questions 59 and 60 refer to the diagram below, which shows the experimental set-up used by a student to find out the rate of photosynthesis of a water plant:

0.05 mL oxygen (O₂) was collected after 20 minutes. What is the photosynthetic rate per unit mass of this water plant?

2.

Questions 59 and 60 refer to the diagram below, which shows the experimental set-up used by a student to find out the rate of photosynthesis of a water plant:

Which of the following modifications of the set-up would increase the photosynthetic rate per unit mass of this water plant?

3.

One day, Adam, Brenda, Calvin and Doris were watching a football match of the World Cup. The following are their dialogues about the heartbeat rate of the football players.

(1)Adam: “Hey! The football players need more energy than us at rest, so their heartbeat rate is higher.”

(2)Brenda: “No, they are well-trained. They can breathe deeper such that they have a lower heartbeat rate.”

(3)Calvin: “Wrong! They have a stronger heart to pump blood. So, their heartbeat rates should be lower than ours.”

(4)Doris: “I partially agree with Calvin. They have a lower heartbeat rate because their arteriole walls are stronger to pump more blood.”

Whose view is correct?
