Explanation / Answer

The answer to question 7 is option (b) Ca++

Question 8.

The answer should be option (a) into the sucrose solutions

- the sucrose solutions has more negative pressure than the root tissue so water will move into the sucrose solutions.

Question 9.

The answer should be option (b) during depolarizing phase.

- During depolarizing phase the inside of the membrane become positive and outside become negative making the membrane potential positive temporarily.

Question 10.

The answer should be option (a) HCL

- Pepsinogen is converted to its active form by HCL released by the parietal cell in stomach lining.

Hopefully it helps if problems arises plz comment.
