The muscles that contract (during cold or fright), the slanted hair follicle is pulled upright, dimpling the skin surface with goosebumps are called arrector pili muscle.
The arrector pili muscle are tiny muscle that attaches to the base of the hair follicle at one end and to the dermal tissue on the other end. When the body feels cold or fright the body generate heat and the arrector pili muscle contract all at once, that causes goosebumps on the skin.
The arrector pili muscle acts as the thermoregulator. Straight stand hair increases air trapping, so that the heat loss from the body decreases. The arrector pili muscle are mediated by the sympathetic nervous system.

Answer:
A fusion protein can be sythesized to carry a specific tag, which is useful in identifying the proteins in various experiments. Fusion proteins with the FLAG epitope bind to specific anti-FLAG antibodies and carry this extra sequence: Asp-Tyr-Lys-Asp-Asp-Asp-Asp-Lys. The bioteh company that sells anti-FLAG antibodies states that fusion proteins carrying the Flag epitope display the sequence on the surface of the protein. This is likely <u>A short hydrophilic 8-amino acid peptide</u> because<u> of its hydrophilic nature</u> of the eight residues are <u>Likely to be located on the surface of the fusion protein</u>, making FLAG highly <u>Specific and easily accessible for cleavage by enterokinase </u> and likely to interact<u> with other epitope and domains</u> Al with water.
Explanation:
FLAG, a short hydrophilic peptide consisting of 8 amino acids have been widely used as a fusion tag for purification and detection of a wide variety of recombinant proteins. the 3× FLAG system is an improvement upon the original system by fusing 3 tandem FLAG epitopes (22amino acids). detection of fusion protein containing 3× FLAG is enhanced up to 200 times more than any other systems.
Answer:
a. map unit
Explanation:
The map unit is the unit to represent the chances or the frequency of the recombination between the two genes. It shows the distance between the two genes present on the same chromosome. The frequency of recombination between two genes present on the same chromosome represents the distance between them that is measured in the form of map units. For example, two genes are said to be 10 map units apart if they exhibit 10% recombination. These genes are mapped 10 centimorgans apart from each other on the chromosome.
