The answer is B). Genetic screening basically testing for the genetic traits of an individual. Therefore the answer would be B).
Answer:
Placebo, Is used to describe a substance given in clinical trial that does not contain the drug.
Explanation:
- Clinical trials are done to evaluate the effectiveness of a drug in treating a particular medical symptom or disease.
- In such case a placebo is used as a control in the experiment.
- A placebo contains all the components as the medicine except for the drug that is being tested.
- A placebo is given to one group of patients having the symptoms for which the drug is tested while another group of patients with same symptoms are given the drug.
- If the group that was given the drug show symptoms of cure while the group that was given placebo does not show changes. Then the drug is said to be effective.

Just took the test and they were both correct.
5. Contour interval of the map is 20m
6. Highest elevation of the map is 160m
7. Lowest elevation of the map is 20m
8. Distance between the top of the mountain and the depression is 9.5km approximately
Explanation:
Contours are the geographical lines representing a boundary or border of a place.
5) Contour interval of the map
We see that throughout the map contour lines are spaced at an interval of 20m E.g. 160,140,120,100 etc. Hence, the contour interval of the given map is 20m
6) The highest elevation of the map- Highest elevation of the map would be shown by contour lines of the highest order. Looking at the map we find that section” A” at the left-hand side is marked with 160m contour lines. Hence, the highest elevation is 160m
7) Lowest elevation for the depression- For lowest elevation, we have to look at the lowest contour lines. We see that maximum depth in the depression is marked by 20m contour lines. Hence the lowest elevation for the map is 20m
8) Kilometres from the top of the mountain to depression- For this, we need to calculate the distance between the mountain head and the depression. We can calculate the distance using a non-extendible nylon thread. Calculating it we get the distance of the thread as 9.5cm (approximately).
Since the scale of the map is 1 cm=1 km Hence the distance is 9.5km
The correct answer is B.
According to base pairing rules, A will always pair with T and and G will always pair with C. This pairing happens in DNA.
When it comes to RNA, there is a slight difference. Thymine is never found in RNA but is replaced with Uracil. So instead of Adenine pairing with Thymine, it will be Uracil which takes the place of Thymine.
It is important to note that Thymine in DNA will code for Adenine in RNA because Adenine is found in RNA base sequence. However whenever Adenine in DNA wants to code for a complementary base to copy on <span />RNA, then Adenine will call for Uracil, not Thymine.
