Two criteria that would identify the three muscle tissues are myofibers and nuclei.

There are three types of muscles:

1. Skeletal-Contains many nuclei along the length of the muscle cell. The nuclei are displaced peripherally. The skeletal fibers are arranged parallel. The myofibril is composed of bands.

2. Smooth-This tissue contain spindle-shaped cells with a single central nucleus. Smooth muscle fibers are shorter than skeletal.

3. Cardiac-The fibers of cardiac muscle are not simply parallel. Cardiac muscle fibers are long cylindrical cells with one or two nuclei.

One of the goals of the forest service in reference to wild horses is to _____.

djyliett [7]

Correct answer: C) Create revenue for the United States government through the sale of wild horses to conservationists

There are various goals of forest service in reference to wild horses but its main goal is to prevent inbreeding of horses in order to avoid genetic abnormalities. Because of inbreeding genetic disorder might occur that may be transfered to the other horses in the future generations. Genetic anomalies may lead to change in genetic makeup, which can have a harmful impact on the whole species.

<h2>Answer: How does the Ebola virus infect people?</h2>

Ebola virus contains a type of genetic material called RNA, which is similar to DNA and contains the blueprint for assembling new virus particles. Unlike animals and plants, which also use DNA as a repository of information, viruses are not technically alive because they are incapable of replicating without help. In order to create new viruses, the virus must infiltrate a living cell, where it hijacks the host cell’s machinery to fulfill its own goals. In order to get into the cell, Ebola must travel through the cell membrane, which is a barrier that protects the cell from its environment. However, all cells need nutrients, which must have ways of entering the cell; the viruses hitch a ride into the cell via one of these established nutrient-uptake entryways. Ebola virus takes advantage of a non-specific engulfing process called macropinocytosis, which allows the virus to be “eaten” by a wave-like motion of the cell membrane (Figure 1) [2].
