Skeletal muscle fiber is a muscular tissue that is attached to the skeletal system. the skeletal muscle fibers are striated muscles i.e have striations in their structure. The skeletal muscle fibers are voluntary muscles i.e they can be controlled.
Motor unit is a composed of a motor nerve cell attached to a muscle fiber with its axon terminals. Motor nerve cells or neurons are the types of neurons that send impulses from the central nervous system to the responding organ. The muscle fiber may be attached to many neurons not only one neuron. Collectively, all the neurons attached to the same muscle fiber are called motor pool.
A skeletal muscle twitch is the contraction of a muscle fiber in response to the minimum stimulation.
The electrical stimulus is the stimulation of a skeletal muscle fiber by using external electrical impulses. The electrical stimulus is important in many sporting and medical situations.
A latent period is a period between applying a stimulus to a muscle fiber and the response of this muscle fiber by contraction.
What are the answer choices to choose from so i can answer
Answer:
Explanation:
Regarding the HIV cycle, we fear two types of cycles: lytic and lysogenic. In the first mentioned above, the proteins that make up the capsid will replicate. These unite around the nucleic acid molecules, producing new viruses. As a result of this event, lysis occurs, that is, the infected cell breaks down and new bacteriophages are released. Symptoms caused by a virus that reproduces this way in a multicellular organism appear immediately. In this cycle, viruses use the cell's biochemical equipment (ribosome) to make their protein (capsid).
On the other hand, there is another cycle in which the production of viral components is shut down indefinitely. This type of multiplication is called lysogeny or lysogenic cycle and is a well established phenomenon for bacterial viruses. The symptoms caused by a virus that reproduces itself through the lysogenic cycle in a multicellular organism may take time to appear. Diseases caused by lysogenic viruses tend to be incurable, such as AIDS and herpes. For this reason that after this initial symptoms, like flu, is going to disapear and other symptoms of HIV infection will lie dormant for many years.
Answer:
The correct answer will be option-A
Explanation:
In the pedigree analysis, the description of a trait help shows the relation of a trait linked to a gene.
The pedigree analysis is usually used to determine the heredity of a disease in a family which has been described in the question also as
1. The trait is rare and present in both sexes- this shows that it is independent of sex chromosomes and since is rare is recessive.
2. A consanguineous mating- mating between close relative which result in autosomal recessive trait as the genes for the trait must be present on both the parents which happen only when they are closely related.
Thus, option-A is the correct answer.
The hypothesis or something that the experiment is about
