You are conducting a study on the health of people who have been exposed to radiation and those who have not been exposed to rad
iation. Which of these methods of obtaining data should you most likely adopt and why? a. an observational study because it involves the pre-existing condition of the subjects
b. an experimental study because it will give the most accurate results
c. an experimental study because results can be obtained much faster using this technique
d. a sample survey with only people who were not exposed to radiation because it involves random selection
e. a sample survey with only people who were exposed to radiation because it involves random selection
If you are conducting a study on the health of people who have been exposed vs not exposed, the method you should use to obtain data would be an observational study because it involves the pre-existing condition of the subjects.
Option A, An observational study because it involves the pre-existing condition of the subjects
Explanation:
In an observational study, a researcher's aim is to observe the effect of an unusual condition, medicine, treatment, or any other intervention on the subject of the experiment without differentiating whether the subject was ever exposed to any such condition or not. Also, this kind of study involves study of pre-exposure condition as well thus, it becomes easy to identify what are the impacts of any treatment/medicine/unusual condition.
Well parents pass on genes to an offspring for one for another the parent will not always pass a gene for a certain trait on, if the trait is not a dominate gene it has the chance of getting replaced by the other parent's more dominate trait
Karyotype examination needs to be done at metaphase.
In karyotype test, the examiner is trying to find whether the chromosome is having any abnormality. In metaphase, the chromosome is easier to count and observed. A chemical (<span>colchicine) will be given to make the cells stuck at metaphase. </span>
The data table refers to a visual method consisting of classified columns and rows used to organize the relevant information in the database of computers. It usually depicts numerical data in a grid format. It helps to arrange diverse to allow data to be easily interpreted and assessed. They are widely employed in the financial analysis process or as instruments for conventional web design.
