Question

12. Two teams of scientists hiked 10 kilometers to different study sites. Before their hike, the Valley

team ate a lunch of mostly protein. The Mountain team ate a lunch of a mix of starch and protein, but
hiked at high altitude, where there is much less oxygen. Which team probably had an easier time
hiking?
a
Both teams had an easy time hiking because their digestive systems broke down proteins
into amino acids for cells to release energy.
b
Neither team had an easy time hiking: the Valley team's cells needed more glucose from
broken-down starch for a reaction, and the Mountain team's cells needed more oxygen from
air.
С
The Mountain team had an easier time hiking: their cells released energy from protein
reacting with glucose, which was broken down from starch in the digestive system.
d
The Valley team had an easier time hiking; their cells released energy from protein breaking
down in the digestive system, which then combined with oxygen in cells.

Answer 1

Answer: B. Neither team had an easy time hiking; the Valley team's cells needed more glucose from broken-down starch for a reaction, and the Mountain team's cells needed more oxygen from air.

Step-by-step explanation:

Before the hiking by the scientists, we are told that the Valley team ate a lunch of mostly protein while the Mountain team ate a lunch of a mix of starch and protein, but hiked at high altitude, where there is much less oxygen.

Based on the above, none of them had an easier time hiking. This is because since the cells of the Valley team who mostly ate protein, need glucose in order for a reaction to occur. For the Mountain team, even though they are a mixture of starch and protein, they went higher which reduced where there was less oxygen. This will have resulted in a hard time for them.

Therefore, neither had a easy time hiking. The correct option is B.
