Answer:
1.Vascular tube is used for vascular surgery and is very small in size with very small diameter and thickness,thus a little change in environment can also affect there result.
2.When testing for tension in the polymer it is very important to consider the strain rate as the increase in strain can cause the material to break.Therefore not only tension test but also strain test is required.
Explanation:
Answer:
b. False
Explanation:
These components are not sufficient to successfully perform a PCR reaction. Deoxynucleoside triphosphates (dATP, dGTP, dCTP, dTTP) are missing so that the PCR reaction can occur perfectly.
The PCR technique allows a specific fragment of the DNA molecule to be amplified thousands of times in just a few hours. This technique revolutionized research in molecular biology because it had taken a long time for DNA amplification. From PCR it is possible to obtain enough copies of a part of DNA to detect and analyze the sequence that is the target of the study.
For a PCR reaction to be performed a solution with some components must be prepared. These components are:
- Magnesium chloride buffer (to optimize reaction and act as a cofactor for polymerase)
- Forward and reverse primers (to customize the start of the enzyme reaction)
- DNA polymerase (Enzyme required for replication of desired DNA region.)
- DNA Template (the DNA to be copied)
- PCR-grade water
- Deoxynucleoside triphosphates: dATP, dGTP, dCTP, dTTP (act as bricks in the construction of DNA molecules).
Answer:
Slime molds, decompose decaying matter. The animal-like protists must "eat" or ingest food.
Explanation:
<span>Cytokines are tiny protein hormones that normalize immune
responses and facilitate cell-to-cell communication. The disproportionately
high levels of cytokines released by T cells enter the bloodstream and increase
the number of symptoms, including fever, biliousness, vomiting, diarrhea, and
sometimes tremor. Superantigens which includes staphylococcal toxins that may
lead to food poisoning and toxic shock syndrome.</span>
Proteins perform numerous functions in the cell membrane, one of which is to regulate the movement of materials, atoms of elements and other ions as they are entering and exiting the cell. These proteins that play this significant role, would be classified as transmembrane proteins, which are specific kind of intergral proteins.
