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.

You can measure and describe climate by walking out the door and describing current atmospheric conditions. true or False

Xelga [282]

Answer:

The answer is "False."

Explanation:

The sentence above is stating that you can "measure" and describe climate by "walking out the door and describing current atmospheric conditions." This is "false" because climate cannot be measured by qualitative descriptions or subjectively. Measuring it entails quantity which is objective in nature. An example of this is by using "thermometers" or "rain gauges."

Although you can describe the atmospheric condition or the climate just by walking out the door, you can never measure it.

Thus, this explains the answer.
