The answer is a hair root.

Nuclear DNA is commonly extracted from the hair root. The hair root consists of keratinocytes. Keratinocytes are cells found in the epidermis. As all other cells, they contain DNA material. When keratynocites die, they get converted into keratoid material in the process of cornification. As a consequence, dead cells do not contain DNA material. Therefore, the hair root is the best source of nuclear DNA than shed or cut hair when working with hair sample.

The biofilm can present one of the most important species of microorganisms, depending on the duration and its location. Gram-positive, Gram-negative and yeast. In addition, the cellular elements may be attached to the biofilm, such as platelets, for example, when the biofilm is installed on the blood-soaked surface.Several factors contribute to the formation of biofilms.

In addition, the cellular elements may be attached to the biofilm, such as platelets, for example, when the biofilm is installed on the blood-soaked surface.Several factors contribute to the formation of biofilms, depends primarily on the number and type of cells present in the liquid to which the surface is exposed and the rate of flow of this liquid across the surface. The physical chemical properties of the surface, the nutritional composition and ambient temperature will also interfere with this speed. The presence of antimicrobials in the medium may affect the formation of biofilms.

ASAP Why is ATP used as an active energy source over glucose? A. It is more abundant in food sources. B. It releases its energy

Rudik [331]

Answer:

Explanation:

Glucose is an organic molecule that stores ATP or energy while Adenosine triphosphate (ATP) is an energy-carrying molecule.

ATP used as an active energy source over glucose because ATP is a shorter process and releases energy in a single reaction as glucose first converted into ATP and then used as energy in cellular respiration.

Hence, the correct option is "B".
