The rapid depolarization phase
of myocardial contractile cells is due to the Na+ ions. Sodium ions are essential
for regulation of blood and body fluids, communication of nerve impulses, heart
activity, and metabolic purposes. Physiologically, it survives as an ion in the
body. Sodium is needed by
animals but is not needed by plants. The human prerequisite for sodium<span> must be less
than 500 mg per day. </span>
Answer:
The correct answer is myofibrils
Explanation:
The fundamental part of the muscle cytoskeleton is made up of myofibrils that are the contractile elements of skeletal muscle cells.Muscle fibers are made up of myofibrils, membranes, and cytoskeletal networks that anchor contractile fibrils to the sarcolemma. Myofibrils are composed of repeating contractile units known as sarcomeres and are perhaps the most ordered macromolecular structures in eukaryotic cells. Myofibrils are made up of actin and myosin filaments that are large polymerized protein molecules responsible for actual muscle contraction.
A valid concern that Amelia might have is C. The regulations will be more burdensome than in other business structures.
A corporation refers to an organization that is authorized to act as a<em> single entity</em>. A <em>corporation</em> is a legal entity and is distinct from its owners.
It should be noted that under law, <em>corporations</em> can loan and borrow money, enter contracts, sue, own assets, etc. The purpose of a corporation is to make a profit.
The concern for Amelia will be the fact that a corporation is highly regulated. It's usually monitored by government agencies. There are also <em>regulations</em> that are put in place in order to protect the rights of employees. Therefore, this may be a challenge for Amelia since she may not have the freedom like that of a sole proprietor.

Answer;
-DNA
Explanation;
-DNA stands for deoxyribonucleic acid. It's the genetic code that determines all the characteristics of a living thing.
-It contains the genetic instructions for the development and function of living things. These instructions are needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the activities in our bodies.
During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses. The chromatin coils and becomes increasingly compact, resulting in the formation of visible chromosomes. Chromosomes are made of a single piece of DNA that is highly organized.
