Answer:
Im not 100 percent sure but I think C because a chemical change occurs when the chemical has broken composure so I think its C.
Answer:
Photosynthesis stores energy, and respiration releases energy.
Explanation:
When plants doing photosynthesis, they will catch the energy from sunlight. The reaction then will store the energy by making glucose. Glucose has high energy that can be released by doing respiration.
Respiration will break down glucose using oxygen and the energy stored inside glucose is released. The energy will be used to synthesize ATP and ATP will be used as main energy.

Answer:
Carcinogenic
Explanation:
A carcinogenic substance is able to modify or damage the genome in a way which promotes the formation of cancerous cells. Cell cycle checkpoint proteins are very crucial for the progression of normal cell cycle. They check for any anomaly in their designated step and halt the process if it is detected. Repair mechanism is activated and cell cycle does not progress till the damage has been repaired.
Here, the pollutant alters the structure of these proteins such that they lose their function. They are not be able to stop cell cycle from progressing even if there is some damage in the genome. The cell divides and gives rise to more damaged cells. Eventually these cells lose their normal function and just keep dividing due to which their division rate becomes double of the normal rate. It can ultimately give rise to cancer which is why the chemical is carcinogenic.
Answer:
Functions of the circulatory, respiratory, and nervous system in gas exchange are interconnected with each other in the following manner:
The circulatory system is responsible to pumps blood around the body. The circulation system allows the absorption of oxygen and releases carbon dioxide in the lungs and the Respiratory system also take oxygen in and releases carbon dioxide. The circulatory system and respiratory system work hand in hand. The brain or nervous system monitors gas or oxygen level in blood and regulates respiratory rate.
