Answer:
50%
Explanation:
DNA replication is a semi-conservative process. It means that after DNA replication, the newly formed DNA molecules have one parental strand and one newly formed strand. The cells in the experiment have DNA with 15N. After one round of DNA replication, each DNA molecule would have one parental DNA strand with 15N and one newly formed DNA strand with 14N.
However, after the second round of DNA replication, each hybrid DNA with strand having 15N and the other with 14N would be unwound. The parental heavy DNA strands would be present in the 50% of the newly formed DNA while the rest 50% of DNA molecules would have both strands with 14N (both light strands).
Weather is the area's day-to-day conditions and climate is the area's average conditions. a natural phenomenon that maintains Earth's temperature range.
The independent variable of an experiment is the one that is intentionally changed or manipulated to see the results of changing said variable.
We are told that in each different group, the amount of caffeine that is given to the dogs changes - in the control group, they get no caffeine, in the 2nd group, they get 10 mg of caffeine each, and in the 3rd group, they get 50 mg of caffeine each.
Therefore, since the amount of caffeine that is given to the dogs is the only variable that is being manipulated, this is the independent variable.

Answer:
A tear in right rib muscles has caused the muscles to spasm it would prevent inspiration.
Reason:
As it is cleared that during inspiration, the intercostal muscles contract, the ribs move upward. the diaphragm flattens and move downward. As a result the chest cavity become open and air move into it. However if the muscles of rib tears then rib will not raise. As a result there will be difficulty in inspiration/
