<span>In response to an increased workload, cardiac myocardial cells will increase in size. Myocardial cells are the muscle cells within the heart. These cells naturally increase in size as the heart enlarges during development. The cells can also grow during extensive exercise, heart disease, or due to an injury to the heart muscle (such as a heart attack).</span>
Answer is A. A Hox gene
Hox genes are a series of genes that controls the differentiation of cells and tissues in an embryo by turn on and off other genes. If Hox genes express incorrectly, a major changes in the morphology of the individual can be seen.
Let’s understand this with an example: The Ultrabithorax, a Hox gene determines the Third thoracic segment in <em>Drosophila melanogaster</em>. Third thoracic segment displays a pair of legs and a pair of reduced wings used for balancing. In the mutant<em> Drosophila</em> the functional Ultrabithorax protein is absent. Due to this mutation, the third thoracic segment now expresses the same structures found on the second thoracic segment, which contains a pair of legs and a pair of wings which are fully developed .
The number and appearance of chromosomes in a cell is called a karyotype. A karyotype can only be seen and studied with a microscope. ... Karyotype analysis can reveal abnormalities, such as missing chromosomes, extra chromosomes, deletions, duplications, and translocations.

Nucleic acids also typically contain phosphorous, and nitrogen plays an important structural role in nucleic acids and proteins. The proteins, being made up a diverse set of amino acids, have, in addition to carbon, hydrogen, oxygen, and nitrogen, the elements sulfur and selenium.
