<span>1. One common interaction between biotic and abiotic components of an ecosystem is photosynthesis. Sunlight is abiotic (solely energy), and it fuels the synthesis of sugars and proteins inside plant cells once it is taken up by plant leaves. </span><span>This process also produces oxygen.

2. Biotic factor that can affect the size of a population in a specific ecosystem:
<span>Number and kinds of predators in the ecosystem.
</span><span /><span>
Predator-prey relationships
When the moose population is high on Isle Royale, the wolves have more food source from preying on the moose. This supports an increase in the wolf population.</span>
<span /><span>
3. Temperature
You can change the temperature to freezing it will affect the aquarium because the organisms will not be able to tolerate the new environment if they are species that thrive in warm temperatures.

A protein biochemist attempted to determine the amino acid sequence of a decapeptide. Use the results from the trypsin, chymotry
Maksim231197 [3]

Answer:

The possible sequence of the decapeptide is Met-Val-Lys-Tyr-Thr-Trp-Ala-Arg-Pro-Phe.

Explanation:

The cyanogen bromide cleaves the carboxyl end of Met (methionine and non-peptide). Trypsin cleaves on the C-terminal of Arg and Lys, however, not on the N-terminal of Pro, which signifies that Lys is the last amino acid in T2. Hence, Met-Val-Lys----. The middle part of the sequence can be predicted from the digestion done by chymotrypsin.

The chymotrypsin cleaves on the C terminal of Phe, Trp, Tyr, however, not on the N side of Pro. CT3 exhibit Lys, Met, Tyr, Val, as Met-Val and Tyr are the initial three amino acids, therefore, Tyr must be the fourth one. Now the sequence will be Met-Val-Lys-Tyr...

CT1 possesses Ala, Arg, Phe, Pro, as chymotrypsin cleaves the C side of the Phe, thus, the last amino acid should be Phe. Also, CT1 has Ala as the first amino acid. Also, trypsin does not cleave on the N-end of Pro. Thus, the sequence of CT1 strands will be Ala-Arg-Pro-Phe.  

In CT2, chymotrypsin cleaves on the C-side of trp. Thus, the sequence of CT2 strands as Thr-Trp is found in the middle. Thus, the whole sequence of the decapeptide strand will be:  

Met-Val-Lys-Tyr-Thr-Trp-Ala-Arg-Pro-Phe.

How does the Earth compare in orbital speed to the other planets?
sukhopar [10]

Answer:

Earth is fairly quicker than all the others, as they are so much larger.

Scientists want to determine how closely related chimpanzees are to humans. Which data would give the MOST accurate comparison?
ipn [44]

The correct answer is option B) their DNA sequences.

The best comparison for finding out the evolutionary relationship between two organism is the comparison of their DNA (deoxyribonucleic acid) sequence. The organisms, which are more closely related to one another share more similarity in the DNA sequence as compared to the distantly related organism, so, the comparison of the DNA can help in determining the evolutionary relationship between the organism.
