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.

Answer:
The correct answer is A. transplanted organs contain antigens that can trigger white blood cell activity
Explanation:
The body's immune system is designed to seek out and destroy any foreign object it finds in the body, such as a cold or flu virus - or a transplanted organ. The process of destruction of the transplanted organ is called rejection.Immunosuppressive drugs will be provided to prevent your immune system from damaging the transplanted organ. Organ transplants require the use of immunosuppressive drugs capable of controlling the immune response triggered by the presence of antigens foreign to the body itself. The group of immunosuppressants is made up of drugs indicated both in the prevention of rejection of the transplanted organ and in its reversal.
Answer:
Deforestation leads to the loss of biodiversity and of indigenous tribes’ homes. Deforestation also affects billions more people around the world indirectly, through its impact on climate change, water and nutrient cycling and food availability. The world’s benefit from conservation far outweighs the costs to the owner, such as the profit they lose by not logging. It would thus make sense for the wealthier North to simply pay the tropical countries in the South to conserve and protect their forests.
