Answer:
C) Re-do the measurements, several times, and take the average density before making a decision.
Explanation:
For the correct identification of the metal, weather its nickel or copper, Carl should repeat the experiment several times and take the average density before making the decision. It is important because it reduces the chance of error and ensure the data integrity. The more the sample size is, lessen would be the error.
They store it as adipose tissue because it also provide heat, insulation, and protection.
Answer:
A) Effect of findings on other family members would be most important factor.
Explanation:
Genetic research is done on human DNA to know the genes and environmental factors associated with certain disease.
Institutional review board (IRB) is the regulatory authority to protect the rights of subjects invloved in a resaerch.
The genetic reaerches usually involve families, so the researcher subjects and the result of research is related to all subjects that cause increased information flow between subjects and effect their decision to partcipate independently in research. Also, if the research involve therapeutic studies special precautions would be taken to choose the subject
Answer:
The average density of deer in 1923 was 1 deer per 8 acres
Explanation:
Given -
In 1923, the population of deer rose to 
The density of any species is equal to total population divided by total area of the land in which this population is residing.

Where d represents the density
P represents the population and
A represents the area of land
Substituting the given values in above equation, we get -

Thus, the average density of deer in 1923 was 1 deer per 8 acres
