Answer:
The correct answer is option (D) "His- strain grows on an his- plate".
Explanation:
The Ames test is a procedure that allows to detect if a given compound can cause mutations on a tested organism by growing strains of bacteria that require histidine (His-) to growth, since they are not able to produce its own histidine. In the Ames test, the bacteria is exposed to a given compound and is grown in a medium with small amount of histidine (his- plate). If the His- strain grows on a his- plate, it means that the bacteria has mutated to synthesize its own histidine and it is considered as a positive result on a the Ames test.
The basement membrane is the thin, non-cellular structure of connective tissue that separates the lining of an internal surface and external surface from underlying connective tissue in metazoans.
The epithelium is a type of body tissue that covers all internal and exterior body surfaces, lines hollow organs and body cavities, and makes up most of the glandular tissue. The body comprises four types of tissues; depending on the location, connectives, muscular, nervous, and Epithelial, which perform the function of protection, secretion, and absorption.
Some examples of epithelial tissues in your body are the outer layer of the skin called the epidermis, the sweat glands, respiratory tract lining, intestines lining, etc. you can also read more on Epithelial tissue.

Explanation:
As I think vector is the correct one.
Because their TEETH ARE MISALIGNED AND THEY USUALLY POSSESS LONG TONGUE. Respiratory illness is common in people who have down syndrome and their unique airway anatomical factors makes airway management difficult during respiratory distress. For instance, they have narrower upper airway and smaller trachea.
Answer:One EcoRI site can be found in 4096 bp.As EcoRI can not cut a sequence if it is not complete, so 732421 recognition sites in human genome can be found. As you know human genome is linear genome, and when you digest it with Restriction Endonuclease having one recognition site, it always gives two fragments.
Explanation: (Idek how to explain it tbh..sorry :C )
