Answer:
The correct answer is a) It brings a transport liquid into close contact with all cells in the body.
Explanation:
The circulatory system helps in bringing the blood which is a transport liquid in close contact with the cells present in our body. This helps in gas exchange between cells and blood. The circulation of blood in the body occurs by the pumping of blood by the heart into arteries, veins, and capillaries.
This circulation of blood plays many other vital functions like transport of nutrients to the cells, transport of waste products from the cell to outside the body, transport of hormones, maintenance of body temperature, etc.
So all these processes become possible when transport liquid comes in contact with the cells. Therefore the right answer is a.

Plants living in dry areas face conflict.
EXPLANATION:
- Since they live in dry areas they will undergo more transpiration.
- If they open stomata during the day there will be excessive loss of water vapor that will result in their death.
- Therefore plants living in this area open the stomata during the night to obtain Carbon dioxide.
- This checks the loss of water through transpiration and provides the carbon dioxide for photosynthesis.
