<u>Answer:</u>
The correct answer option is B. Green wavelengths are the least used in photosynthesis.
<u>Explanation:</u>
Plants have a pigment in them called as chlorophyll. This chlorophyll is able to absorb only certain wavelengths of the light within the light spectrum.
From that visible light spectrum, chlorophyll is only able to absorb light of red and blue wavelength. The green light is not absorbed by the by chlorophyll as it is reflected back.
Therefore, this reflection of green light makes the leaves to appear green.
Answer:
The right option for blanks is mRNA, amino acids and polypeptide chain (protein).
Reason:
During protein synthesis first of all mRNA formation occurs from DNA template. Then mRNA come out from nucleus into cytoplasm and bind with ribosome, where tRNA come and binds to mRNA codon with the help of anticodons. and add amino acids. In this way a chain of polypeptide is formed.
A plant is is a Eukaryotic (if that’s what you meant) and here are some note I took last year, hope they help :)

Answer:
e. All of the choices are correct.
Explanation:
Bacteria are present almost everywhere on Earth. Many bacteria like cyanobacteria play an important role in fixing the atmospheric carbon in the form of an organic molecule. These organic molecules then used to gain energy.
Many nitrogen-fixing bacteria like Rhizobium, Azotobacter, etc plays an important role in providing nitrogen to plants which is important for their growth. Many bacteria decompose organic matter into simpler form and recycle the nutrients present in them.
So bacteria like <em>Pseudomonas putida</em> decompose waste and clean the environment, therefore, they also help in bioremediation. So the correct answer is e. All of the choices are correct.
