Answer:
I would expect to see 3 bands after completing DNA gel electriphoresis and staining the gel.
Explanation:
The restriction enzyme Hind3 has two Recognization sites in the 400 base pair long DNA molecule.
As a result the restriction enzyme Hind3 with generate 2 cuts in the target 400 base pair long DNA molecule.
The number of 2 cuts in the target DNA molecule will generate 3 DNA fragments.From this point of view it can be stated that 3 bands will form after completing DNA electrophoresis and staining the gel.
Answer:
The correct option is D) All of the answers are correct.
Explanation:
The walls of the capillaries are thin due to which the processes of diffusion and filtration becomes lot easier in them. Gases such as oxygen and carbon dioxide cross the capillary walls through diffusion processes. As the walls of the capillaries are much thinner than that of veins and arteries hence. the processes of filtration and re absorption occur easily through them.
An example of something that does not have mass would most likely be air. Because in order for something to have mass, it must take up space and have shape. Anything that you can think of that does <u>not</u> have <u>space or shape</u> does not have mass.
After the macrophage fails the Helper T Cell stimulates the B cells (create antibodies) if pathogen is extracellular and Cytotoxic T Cells (killer T cells, release perforin) if pathogen is intracellular. Once the pathogen is killed the B Cells create Memory B Cells and the Killer T Cells create memory T Cells.

What we eat (our environment) and genetic variables come together in epigenetics.
Describe epigenetics.
A branch of genetics called epigenetics investigates how variations in the environment might affect how genes are expressed.
DNA methylation, histone alterations, and non-coding RNA pathways are examples of epigenetic mechanisms.
In conclusion, epigenetics is the fusion of genetics and environment.
