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.
<h2>Answer is option "C"</h2>
Explanation:
- To clone a plant means to create an identical copy of an adult plant. These identical copies become young plants that in turn become adult plants that can be cloned again. This process can go on indefinitely
- The most common method of cloning plants and the one that has been used for a very long time is that of taking cuttings from an adult plant. A cutting is a stem or leaf that is cut from an adult plant. The cutting is then planted into moist soil or other moist growing media. The cutting will produce roots of its own and then become a whole new plant identical to the original adult plant. Not all plants can be cloned via cuttings, though
- Vegetative proliferation works in light of the fact that the finish of the cutting structures a mass of non-particular cells called a callus. With karma, the callus will develop, gap and structure different specific cells (roots, and so on.), in the end framing another plant
- Hence, the right answer is option C "Clone the plant"

</span>Red light has a longer wavelength than violet<span> light. The refractive index for red light in glass is slightly different than for </span>violet<span> light. </span>Violet<span> light slows down even more than red light, so it is refracted at a slightly greater angle</span>
It’s because your heart speeds up to pump extra food and oxygen to the muscles and beathing speeds up to get more oxygen and to get rid of more carbon dioxide
