Answer:A
Explanation:Binary Fission, meaning ‘getting divided into half’ is a type of asexual reproduction where a single living cell grows twice its size and then splits to form two identical daughter cells, each carrying a copy of the parent cell’s genetic material. Examples of cells that use binary fission for division
it is not a prescription drug
As we know Benzene undergo
Electrophilic Substitution Reactions. In case of substituted Benzene the incoming Electrophile is substituted either at
<em>Orto , Para</em> position or
<em>Meta</em> position. If the substituent is
Electron Withdrawing in Nature then the Electrophile will go to <em>meta</em> position. When the substituent id
Electron Donating in Nature then the incoming electrophile will be directed to <em>ortho</em> and <em>para</em> position.
In Benzenesulfonic Acid the substituent is
Sulfonate (-SO₃H), it has a strong electron withdrawing effect. So on
Nitration the Nitro group will be oriented to <em>meta</em> position and
3-nitrobenzenesulfonic acid is formed. On further Nitration 3-nitrobenzenesulfonic acid will be convert to
<span>
3,5-dinitrobenzenesulfonic acid because both Sulfonate and Nitrate groups are <em>meta</em> directing.</span>
Answer:
The total water content in the earth remains nearly constant.
Explanation:
- The amount of water on earth is nearly same as the amount of water that was on earth in Mesozoic era.
- Plants and animals use water as a raw material in their growth, but that water is eventually returned to earth.
- When the UV light breaks the water molecules in higher atmosphere, some water is lost.But it is compensated by the water that enters the earth through meteors and comets.
- The water content is not constant but through the series of biochemical reactions,the water level is nearly the same.
Magnesium phosphorus - replace with ide because it non metal in periodic table so
Answer : Magnesium phosphide
