8 0

Answer:

400-450 nm
550-700 nm

Explanation:

Chlorophyll pigments (mainly chlorophyll a and b) absorb the red and blue spectrum of visible light in the electromagnetic spectrum for photosynthesis. This is why leaves appear green (and occasionally orange) because this visible light portion is not absorbed. The blue light absorbed by leaves ranges between 400 – 450 nm while the red light ranges between 500 nm and 700 nm.

Explain the need for ventilation systems in a multicellular organism

babunello [35]

Ventilation systems are needed in a multicellular organism to actually obtain oxygen and give out carbon dioxide. Without this ventilation system, it would be very difficult for multicellular organisms to survive. It has been also observed that surface diffusion is not enough for a multicellular organism to breath.

Provide the term for base triplets on tRNA

Semmy [17]

The answer is anticodon.

Anticodons are base triplets on transfer RNA (tRNA). tRNA carries amino acids to the ribosome for protein synthesis. The prefix anti- suggests that anticodons are complementary to the codons on mRNA. Codons are base triplets on mRNA. So, anticodons of tRNA pair with codons of mRNA in the process of protein synthesis.
