Answer: True
Explanation:
DNA is a biological evidence. It is a heredity material which is present in all organisms on earth. The DNA in humans can be taken as sample from nails, bones, blood, skin, hair and other sources.
The DNA samples can be taken so as to establish the identity of the culprit, victim or any one which is associated with crime.
The DNA evidence has applicability as a potent evidence in the court of law. Thus utmost care should be taken to preserve it's integrity until it is analysed and presented in the court of law.
Thus the DNA evidence should be collected and preserved in airtight containers so as to prevent the entry of airborne pathogens like bacteria, virus these can contaminate the sample evidence and can make the evidence not of any use.
They were imported from China into the United States in 1881.
The first successful release was in Minnesota in 1916.

Answer:
The pelvis is the best sex-related skeletal indicator, because of distinct features adapted for childbearing. The skull also has features that can indicate sex, though slightly less reliably. Males have a square jawline and the line between the outer edge of the jaw and the ear is vertical. Conversely, in females the jaw is much more pointed and the edge of the jaw slopes gently towards the ear.
Explanation:
Homeostasis is the ability of an organism to stabilise its internal body metabolism in response to changes in the external environment. The ability to carry out homeostasis provides an organism a lot of freedom from the dependence on the external environment. For example, reptiles are cold blooded animals. They require the heat of the sun for body metabolism. But in the absence of heat or in case of harsh winters, the reptiles will not be able to adjust to the temperature and as a result perish. Mammals are warm-blooded animals, being able to regulate their internal body temperature as and when necessary. Winters will affect the warm-blooded animals less because their body will increase in metabolism in response to cold temperatures to raise the internal body temperature. This is possible only through homeostasis.
Sorry i don't understand your question. I am really confused.
