Answer:
C) comparisons to a pressure-temperature chart are only valid if both the pressure and temperature of the refrigerant are stable and know
Explanation:
- Therefore, the room temperature affects also the non-condensables.
- If the room temperature is not stable, then the temperature of the non-condensables shall not be stable, likewise its temperature.
- Thereby, the inferences made without the room temperature stabilizing shall be erroneous.
Answer: The midpoint, or number that divides a series of value into two group of equal numbers of value is refered to as "MEDIAN".
It can also be used when they is extreme values like the national incomes.
Explanation: The median is a value at the midpoint of a frequency distribution, it is used to denote the center of a line of numbers, it also tells the higher part and the lower part of the numbers. In statistics, median tells the probability of an event to occurs is equal. When median is equal to mean, it means that the frequency of numbers are properly arranged from the lowest order to the highest order.
National household income values are values with frequency of numbers, median can be used to know the midpoint of the numbers and to determine to lower part and the higher part.
Evolution isn't a steady process. When the environment changes, the organisms have to adapt quickly or perish. A theory known as punctuated equilibrium accounts for this. Any changes in then environment brought on by natural or artificial changes will cause animals to evolve to those changes. It may be that they just have to migrate where the climate is more suitable. When you look at geologic sequences, you can often see the different environments as the climate changed and a new suite of animals and plants took over.
<span>It is fantasy to claim that the "old" environment was stable before humans came along unless you live in the tropics. There was a mile of ice over NYC and Chicago 15 thousand years ago. </span>
<span>Geologic changes can affect evolution by creating population splits which allows for speciation. For example, the thrusting up of a mountain range may cause one population to split into two. The separate populations may then evolve on their own sometimes into new niches. One population may stay relatively similar and the other may change dramatically.</span>
The answer to your question is letter B which is basic values. It is one of the forms which is the foundation of the American culture. The American Value System is a system that values are shared by American culture despite the fact that the country is so diverse.
