Answer 2

HEYA!!!!

Here are your answers :

1. Plants are green due to preserve of Chlorophll.

Reason : Chlorophll is a green pigment present in Chloroplasts of cell. These are used in process of photosynthesis.


2. Pepsin is present in the Gastric Juice.

Reason: As, Gastric Juice is secreted by Stomach. This digests the proteins.


3. Ten percent law : The law which is used as during the transfer of energy from organic food from one trophic level to the next, only about ten percent of the energy from organic matter is stored as flesh. The remaining is lost during transfer, broken down in respiration, or lost to incomplete digestion by higher trophic level.

4. Genotypic ratio : The Genotypic ratio of mendel's monohybride cross is 3:1.

5. R- Reduce

R - Recycle

R- Recover.

6. Auxin is one of the growth harmone of plant. This harmone helps in Phototropism.

7. DNA : Deoxyribonucleic acid

8. The circulation which happens twice is called as Double circulation.

ex: most of mammals follow this.
