There are many, and since you didn't specify the choices, some examples include "ff" or "dd" or just two lowercase letters.

Answer:
GAA TTC GCA Original strand
CTT AAG CGT Complimentary strand
Explanation:
The original strand is already given. It is GAA TTC GCA
Now we need to recognize the complementary strand from the pool of options and pair their bases. Names are written with their letters.
Nitrogenated bases that form nucleic acids correspond to purines and pyrimidines.
- Adenine (A) and guanine (G) derive from purines,
- Thymine (T) and Cytosine (C) derive from Pyrimidines.
In the DNA molecule, Adenine (Purine) forms pairs with Timine (Pyrimidine), while Guanine (Purin) pairs with Cytosine. Two hydrogen bonds join the A-T pair, and three hydrogen bonds join the G-C.
Knowing this, we need to find the correct option, which will pair A with T and C with G.
- 1st Strand → CUU AAG CGU → You can eliminate this option because it includes Uracil, which is a base of RNA. Uracil complements with Adenine, but only in RNA, and now we are looking for a DNA complementary strand.
- 2nd Strand → GAA CCT CAT → None of the triplets pair correctly the original strand. It is not complementary
- 4rth Strand → GAA TTC GCA → This is equal to the original strand. It does not complement it.
- 3rd Strand → CTT AAG CGT → The three triples complement the ones of the original strand. This is the correct option.
G ⇔<em>C</em>
A ⇔ <em>T</em>
A ⇔ <em>T</em>
T ⇔ <em>A</em>
T ⇔ <em>A</em>
C ⇔ <em>G</em>
G ⇔ <em>C</em>
C ⇔ <em>G</em>
A⇔ <em>T</em>
Answer:
27 J
Explanation:
1. The equation for ME is PE + KE
2. Therefore 15J + 12J = 27J
During intense exertion or activity involving the muscles, there arises a need for a sudden short term burst of energy. This need for energy is so demanding that it cannot be satisfied through the normal mechanism whereby energy is supplied through aerobic respiration using oxygen.
Therefore the muscle cells must rely on other mechanisms that do not rely on oxygen to fuel muscle contraction and this is where they resort to anaerobic respiration which uses pyruvate to play the role of oxygen as the final electron acceptor. In the process, pyruvate accepts an electron and is reduced to lactic acid in the muscle tissues.
