UNO [17]

Answer:

<u>-blue and red light</u>

Explanation:

Plants produce sugars or carbohydrates during the process of photosynthesis. They absorb light energy from the electromagnetic spectrum with pigments within the thylakoid membrane, like chlorophyll a, chlorophyll b.

Chlorophylls are made of ringed molecules chlorine, a hydrogenated form of porphyrin with a magnesium ion bonded to four atoms of nitrogen. Chlorophyll a shows the most absorption of red light  (642 nm) and blue light (372 nm); while chlorophyll b shows the most absorption at 626 nm and 392 nm.  

Different types of chlorophyll sidechains change the molecules' absorption ranges; A's methyl group is bound at carbon 7,  B's aldehyde (CHO) ring is bound at carbon 7.  Both absorb light from orange-red and violet-blue wavelengths. As such, the best light wavelengths for photosynthesis are within the blue and red wavelengths (425–450 nm) and (600–700 nm).

Llana [10]

Answer:

16 genetically different offspring

Explanation:

This is the case as each parent has the ability to produce 4 uniquely different gametes through independent assortment. With such a scenario where each parent can product 4 uniquely different gametes multiplied by 4 parents, you have 16 offspring. So there's the possibility of producing 16 offspring that are unique.
