Heart rate is the most accurate of the metrics available for measuring the effectiveness of exercise. Therefore, the correct option is D.
Heart rate is a useful indicator of the circulatory response to physical activity and can give an indication of the degree of physical exertion. Heart rate increases during activity to meet the body's oxygen and energy needs. Cardiovascular workload increases with exercise-induced heart rate.
To achieve specific fitness goals, people can set their exercise intensity and monitor their heart rate to ensure they are working within their target heart rate zone. Improvement in heart rate, or the speed at which heart rate returns to normal after exercise, can potentially reveal information about cardiovascular fitness.
Therefore, the correct option is D.

Answer:
The differences between these three ways of heat transfer are that conduction is the transfer of thermal energy through direct contact, convention is the transfer of thermal energy through the movement of liquid or gas, and radiation is the transfer of thermal energy through thermal emission. As you can see, each way of heat transfer has a different way of moving through objects.

Every day they charted whether upstairs and downstairs were either too cold, cold, warm, too warm, or hot. They tallied their results, learning that the two weeks of using both units; the house was a bit too warm. The month where only the downstairs unit was used, they noted downstairs and upstairs were warm. This did not support their prediction that it would be cold.
They began to wonder how upstairs could still be warm during the daytime when only using the downstairs unit. What is the best possible explanation for upstairs being warm throughout the winter month when they only turned on the downstairs unit?
Answer:
Convection
Explanation:
Hot air rises as it has less particles and more volume. This means that when they heat downstairs, the hot air rises to the top. Then, it cools and sinks because cold air has more particles and less volume. It heats up again from the downstairs unit and the cycle keeps going. This is called convection
Answer:
The volume of warm air expands and rises, warming the whole house through convection.

Answer:
The correct answer is minority influence.
Explanation:
According to the concept of minority influence, the smaller groups will affect the individuals on the basis of their opinions and perspectives on the topics, which are not witnessed by many. They develop a perception, which is not common and majorly are from their observations of the things, which are required to get better in the humanity and community.
blood can receive Rh-blood.
Answer:
Rh+
blood can receive Rh+ or Rh- blood.
Rh-
blood can receive Rh- blood.
Explanation:

Answer: An Rh+ person can receive Rh+ or Rh-. An Rh- person can only receive Rh- blood
Explanation: the Rhesus (Rh) group has three types, CDE. Of these, only the D locus is of general importance, and this is the one involved when we talk about Rh+ or Rh-. The D allele is dominant and DD or Dd are the Rh+ type, while dd is Rh-.
Rh- people have an immune response to the D and produce antibodies which causes blood clots and this can be life-threatening. Some Rh- people have anti-D antibodies in their blood, but the level is too low to affect Rh+ people transfused with Rh- blood. This is also unlikely because Rh+ is by far the more common type.
A particular problem arises when a mother is Rh- and the father Rh+ because the baby may be Rh+. If this happens the mother will produce antibodies to the foetus’s blood which will kill it if they cross the placenta. This is avoided by giving the mother Rh immunoglobulin injections during pregnancy which switch off anti-D antibody production.
It is rare for the C and E loci to cause a significant immune response.
