Answer:
B) When reunited, two allopatric populations will interbreed freely if speciation has occurred.
Explanation:
There are five types of speciation: <em>allopatric</em>, peripatric, parapatric, and sympatric and artificial. Allopatric speciation occurs when a species separates into two separate groups which are isolated from one another.

For this problem, use the 10% Rule. That means that every time you move up a level on the Energy Pyramid only 10% of the energy from the previous level is available at that level. Essentially, just move the decimal place over to the left one time each time you move up a level.
Answer:
B
Explanation:
While humans have the same genome, there bear very minute differences (0.01%) between individuals that make them different from one another. The closer you are in a hereditary relationship, the lower this difference. This difference can be used to determine the genetic relationship and is called a DNA fingerprint.
It involves cutting up DNA from a sample using restrictions enzymes and then running the sample on an electrophoresis gel. The resulting bands are compared between two individuals. The more the bands align, especially at regions where people differ alot such as Short Tandem Repeat regions, the higher the genetic relationship between the two.
Answer:
Potassium
Explanation:
Resting membrane potential may be defines as the voltage or charge difference between inside and outside of the cell when the cell is at rest. The resting membrane potential of the cell is -70mV.
Potassium ion channels are leaky channels that are always open and can move into and out of the cell. The potassium ions are responsible for setting of the resting membrane potential of the cell. Inward movement of sodium ions may disrupt the resting membrane potential of the cell.
Thus, the correct answer is option (B).
Answer:
The answer is day 14 - / + 3 days
Explanation:
In a 28-day menstrual cycle the most likely days for a woman to become pregnant is from day 14 - / + 3 days, that is, days 11, 12, 13, 14, 15 and 16. She should be educated, If she is in search of pregnancy, take the vaginal temperature and realize how the viscosity of the abundant flow begins to present.
