The structural level in which the muscle produces the contraction is known as the muscle fiber.

<h3>What is a muscle fiber?</h3>

A muscle fiber is a single muscular cell that is able to contract by using specialized proteins such as filaments of myosin and actin.

This unit (muscle fiber) is able to contract both in vivo and in vitro by establishing suitable environmental conditions (e.g., proper calcium levels).

In conclusion, the structural level in which the muscle contracts is the muscle fiber.

lord [1]

The question lacks the diagram. The diagram has been attached below.

Answer:

1.

Explanation:

Exons may be defined as the coding region of the RNA whereas introns are the non coding region of the RNA. The introns must be removed out from the RNA to makes it functional molecule.

The splicing of the given molecule results in the formation of single mRNA. The 1 splicing of the introns remove intron A whereas the second splicing results in the removal of intron B. The functional mRNA consists of the mRNA with exon 1,2 and 3.

Thus, the answer is 1.

Alexus [3.1K]
<h2>Answer </h2>
  • Hybridization
  • Recombinant DNA
  • Selective Breeding

<u>Explanation</u>

1. Cross-breeding; a method that unionizes gametes of differing genes to create a new individual is hybridization. It is the idea of combining atomic orbitals into different hybrid orbitals that is proper for the pairing of electrons to create chemical bonds in valence bond as per the atomic theory.

2. Cultured DNA molecules from different biological sources is recombinant DNA. They are the molecules are DNA molecules determining by laboratory techniques of genetic recombination to take mutually genetic material from various origins.

3. A process of breeding organisms because of their specific traits is selective breeding. It is the method that grants humans practice animal breeding and plant breeding to selectively develop selective over phenotypic traits
