Answer:
There is little to no sunlight in the aphotic zone.
Explanation:
The aphotic zone is the deepest part of a lake/ocean, so no light is able to penetrate into those depths. Without light, photosynthetic organisms will not be able to undergo photosynthesis and will therefore not be able to survive.
It is important because it allows scientists to classify, group, identify, and properly name organisms through the method of taxonomy. This method was brought about by Linnaeus Carolus.
I really hope this helps! I love science :D
Answer:
1. <u>Phosphoribosyl</u> amine
2. <u>glycinamide ribonucleotide (GAR), a formyl group</u>
3. F<u>ormylglycinamide ribonucleotide (FGAR), an amino group</u>
4. C<u>arboxyaminoimidazole ribonucleotide (CAIR), an amino group.</u>
Explanation:
1. <u>Phosphoribosyl</u> amine will accumulate in bacteria that lack glycine.
2. The intermediate <u>glycinamide ribonucleotide (GAR)</u> will build up in the absence of tetrahydrofolate.
N10‑Formyltetrahydrofolate donates <u>a formyl group</u> to the substrate
3. F<u>ormylglycinamide ribonucleotide (FGAR) </u>will accumulate in the absence of glutamine.
Glutamine donates <u>an amino group</u>
4.<u> </u>The intermediate <u>carboxyaminoimidazole ribonucleotide (CAIR)</u> will accumulate when aspartate is lacking.
Aspartate donates <u>an amino group.</u>
