Answer:
Cell differentiation is the process by which dividing cells change their function. DNA is essential in gene expression, which gives the ability of cells that are specializing to be able to adequately perform the role they are trying to carry out. It is generally understand that all the cells in our body contain the same DNA, yet they carry out different functions. The key is understanding that specific parts/combinations of the genome are activated which changes the function and shape of the cell. Additionally, if the DNA is damaged or mutated in certain areas of the chromosome, it can cause certain differentiated cells to not function properly.
Explanation:
Bacteria are identified by the shape and arrangement of cells. The basic shapes are bacillus, spirillus, and coccus. The arrangements may be described by adding prefixes to the shapes...diplococcus would indicate a pair of round bacteria.

Answer:
Valves of the heart do the endocardium extenstions.
Explanation:
Endocardium is the inner most layer of heart containing tissue that lines the heart chamber and the outer most layer of the heart is called epicardium.
The main function of this structure is to protect the valves and heart chamber.
The endocardium consists of endothelial cells that controls myocardial function.
The homeometric and heterometric regulation is separated by myocardial system.
The endocardium also functions as a blood heart barrier thus controlling the ionic composition withih which the cadiomyocytes bathe.
