Hence, option D is correct.
Chicken is one of the fowl and it is one of the widespread and well-known fowl. It is found in almost all area.
<u>Explanation:</u>
<u>1.Observations of the chicken leg dissection.</u>
- The main observation of the chicken leg dissection is to detect the legs of the chicken and find the muscles, tendons, leg joints and the bones
<u>2. Determine the chicken moves</u>
- Yes, the Movement of chicken can be determined .
- The chicken moves the wings by the push and the pull action with the help of the bones and it turns over the muscles until it reaches the movement.

Answer:
<h2>B. that have complementary sticky ends</h2>
Explanation:
The sealing of nicks between two adjacent residues of a single-strand(ss) break on a double-strand DNA and the joining of double-strand breaks.
This is enzymatically catalyzed by the enzyme DNA ligase.
DNA ligation is the joining ends of 2 DNA molecules by the enzyme, DNA ligase. DNA ligase catalyzes the formation of two covalent phosphodiester bonds between the 3' hydroxyl group of one nucleotides and the 5' phosphate group of another and it is an ATP dependent reaction.
DNA Ligation occur most efficiently between those DNA fragments that have complementary sticky ends.
