Answer:
Yes , when viruses infect us, they can embed small chunks of their genetic material in our DNA. Although infrequent, the incorporation of this material into the human genome has been occurring for millions of years. As a result of this ongoing process, viral genetic material comprises nearly 10 percent of the modern human genome. Over time, the vast majority of viral invaders populating our genome have mutated to the point that they no longer lead to active infections. But, as scientists funded by the National Institutes of Health have demonstrated, they are not entirely dormant.
Explanation:
Answer:
Viruses are continuously changing as a result of genetic selection. They undergo subtle genetic changes through mutation and major genetic changes through recombination. Mutation occurs when an error is incorporated in the viral genome. Recombination occurs when co infecting viruses exchange genetic information, creating a novel virus.

a skeletal muscle generates the greatest tension when it is:
Explanation:
A skeletal muscle generates the greatest tension when it is: partially stretched before being stimulated
Skeletal Muscle generates the greatest tension when the muscle is stretched to an intermediate length, by length-tension relationship.
How tension generates in skeletal muscle?Muscle tension is highest in skeletal muscles when stretched to an intermediate length, as indicated by the length-tension relationship.
When skeletal muscle fiber contracts, myosin heads link to actin to create cross-bridges, and the thin filaments slide across the thick filaments as the heads pull the actin, resulting in sarcomere shortening and muscular contraction stress.
The amount of stress produced by a muscular contraction is determined by two factors: the number of active muscle fibers and the frequency of neural stimulation of the muscle fibers.
Therefore greatest tension generates in skeletal muscle when it is stretched to the intermediate length.

which is not involved with an inflammatory Response
A. Fever - increased temperature
B. Slowed blood flow
C. White blood cells move to the area of infected
D. inflammation in area
This is an inflammatory reaction to an infection in the body. Option D is correct.
What is the inflammatory response?When tissues are harmed by toxins, germs, trauma, heat, or any other cause, the inflammatory response (inflammation) ensues. A fever is induced by the body's attempt to destroy any infections with heat.
Histamine, bradykinin, and prostaglandins are among the substances released by injured cells. Because of these substances, blood vessels leak fluid into the tissues, producing swelling.
White blood cells migrate to the affected location to destroy any germs. Because white blood cells are primarily intended to aid in the killing of infections, sending white blood cells to destroy the pathogen is an inflammatory reaction.
Finally, inflammation results from the body's attempt to cleanse the contaminated region of microorganisms. Similar to the label “inflammatory,” the body will frequently create inflammation in an attempt to cleanse the body of any undesirable infections.
Therefore, option D is correct.

Describe how ions, water and sugar are obtained and transported
through plants. In your answer you should refer to materials moving upwards in a plant and to
materials moving downwards in a plant
Answer:
Explanation:
Water moves through the xylem in a stream called a transpiration stream, up to the leaves of the plant. Sugar is made during the process of photosynthesis. Unlike water and ions, it travels through the plant via the phloem, moving up and down through the plant.

Looking at a stained smear of horse blood and seeing a leukocyte with large red granules in its cytoplasm. I am most likely seeing a granulocyte, an eosinophil in particular.
Leukocytes are white blood cells and there are various types of white blood cells including granulocytes, agranulocytes.
Granulocytes are white blood cells present with granules and produced in the bone marrow. There are three types of granulocyte; they include eosinophil, basophil and neutrophil.
Eosinophils are white blood cells with large granules and they stain red with dye. Their nucleus is also made up of two unsegmented lobes.
