The correct answer is cold fronts
Answer:
Electric current – The net movement of electric charges in a single direction through a wire or conductor. Voltage difference – The force that causes electric charges to flow; charges flow from high voltage to low voltage
Explanation:
Incomplete question. Here are the missing parts.
What will happen to the substances in this diagram to bring the concentrations closer to equilibrium?
A. The solute will flow into the cell from the surrounding environment.
B. Nothing will change--it is already in equilibrium.
C. Water will flow into the cell from the surrounding environment.
D. Water will flow out of the cell and into the surrounding environment.
My answer:
D. Water will flow out of the cell and into the surrounding environment.
The solute cannot pass through and go inside the cell, water has to flow from the cell to the surrounding environment to bring the concentration closer to equilibrium.
Considering the definition of probability, the correct answer is third option: the approximate probability of a moth being brown and yellow respectively is 33% and 21%
Probability is the greater or lesser possibility of a certain event occurring.
In other words, probability establishes a relationship between the number of favorable events and the total number of possible events.
Then, the probability of any event A is defined as the quotient between the number of favorable cases (number of cases in which event A may or may not occur) and the total number of possible cases. This is called Laplace's Law.

In this case, you know that in a moth population, 48 are brown, 30 are yellow, and 67 are black. So, the total number of possible cases is calculated as:
total number of possible cases= 48 + 30 + 67= 145
The number of favorable cases for a moth to be brown is: 48
Then the probability that a moth is brown is calculated as:
= 0.33= 33%
On the other side, the number of favorable cases for a moth to be yellow is: 30
Then the probability that a moth is yellow is calculated as:
= 0.21= 21%
In summary, the correct answer is third option: the approximate probability of a moth being brown and yellow respectively is 33% and 21%
