FIRST LAW OF THERMODYNAMICS *the total heat
energy applied to the system is equal to the sum of the change in
internal energy of the system and the work done <span>by the system.
</span>
SECOND LAW OF THERMODYNAMICS (entropy) *no
process in w/c the total entropy decreases is possible when all the
systems taken apart in the <span>process are considered.
BONUUUUSSS :D
</span>
<span> THIRD LAW OF THERMODYNAMICS *The entrophy of a perfect crystal of a substance at the absolute temp. is zero.

It is true that uni-potent stem cells can only produce cells that are like themselves
Answer: Option B
<u>Explanation:</u>
Uni potent cell as their name suggests can only produce cells that are just like themselves. Compared to the other stem cells that undergo proliferation this produces a tissue of that particular type alone.
Though it can’t be of much use like other cells giving rise to different cell types this is confined to the generation of one particular tissue. The uni-potent cells help to renovate and recreate themselves too. Hence any damaged tissue can be replaced by the uni-potent cell giving rise to the same tissue in case of burns etc.
Answer:
A) The role of bacteria fixing nitrogen is very important because it fixes atmospheric nitrogen in the roots of plants. For example, Azotobacter is a bacteria which lives in the root of the higher plants. The bacteria fixes nitrogen for the plant and the plant gives habitat and food to the bacteria and hence, both get benefit.
B) Nitrifying bacteria are the bacteria which converts ammonia into nitrates. Examples are Nitrosomonas and Nitrobacter.
C) Denitrifying bacteria is a type of bacteria which converts nitrates into atmospheric nitrogen. Examples are Serratia and Pseudomonas.
Answer:
1
Explanation:
Lichen are usually the first thing to grow on bare rock, making them a pioneer species. Fun fact, you can use lichen to determine if the air quality in an ecosystem is polluted.
