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:
The correct answer is <em>They move through an electron transport chain to Photosystem I.</em>
Explanation:
Luminous energy is trapped by a chlorophyll molecule in the <u>Photosystem II</u>. When the pigment molecules absorb light, electrons get in a higher energy level. These excited electrons go through the electron transport chain to an inferior energy level in the <u>photosystem I</u>. When the excited electrons leave photosystem II, they are replaced by new electrons that are extracted from the water molecules. As electrons go through the transport chain, their released energy is used to <u>produce ATP molecules</u>. Luminous energy absorbed in the photosystem I move the electrons to another electron acceptor from where they are transported again and used to produce NADPH molecules. When electrons are eliminated from Photosystem I, they are replaced by new electrons that are coming from the photosystem II through the transport chain.
