Answer:
Geo thermal : Nuclear reactions
Bio mass : plants
Solar : sun rays
Hydro power : Water
Explanation:
Geothermal energy is also used to directly heat individual buildings and to heat multiple buildings with district heating systems. Hot water near the earth's surface is piped into buildings for heat. A district heating system provides heat for most of the buildings in Reykjavik , Iceland.
The major biomass sources currently used are sugar cane and corn to produce bioethanol , and rapeseed for biodiesel production. Other sources are also used such as sunflower seeds, soybean, canola, peanuts, jatropha , coconut and palm oil for biodiesel, and wheat, sugar beet, sweet sorghum and cassava for bioethanol
Conversion of energy from sunlight into electricity
Hydropower or water power is power derived from the energy of falling or fast-running water, which may be harnessed for useful purposes.

<u>Answer:</u>
<em>Colchicine is also known as mitotic poison. When it is added the separation of chromosomes of daughter cells are stopped. </em>
<u>Explanation:</u>
This is because the formation of spindle fiber is not allowed in the mitosis phase. Basically it is the process of arresting the mitosis at metaphase to study the chromosomes properly.
The addition of colchicine prevents the chromosomes to move to opposite poles. It makes the cell polyploidy. Hence the of addition of colchicine is the polyploidy of the cell.
The <em><u>MESOSPHERE </u></em>is the coldest layer and the hottest layer is <u><em>THERMOSPHERE </em></u> is the hottest layer in the atmosphere.
This process is called Denitrification. The process is undertaken by the denitrifying bacteria, whose action is converting nitrates in the soil to free atmospheric nitrogen and therefore, depleting soil fertility and reducing agricultural productivity. Examples of denitrifying bacteria are thiobacillus denitrificans, micrococcus denitrificans among others.
