The term would be genetic drift.
Genetic drift, also known as allelic drift, is one of the basic mechanisms of evolution, in which random changes in alleles from generation to generation in a population occur.
Answer:
0 solutions
Step-by-step explanation:
2n + 4 = 4n + 1 - 2n
↑
first combine like terms (right side)
2n + 4 = 2n + 1
but this part you can tell that there's 0 solutions, because both sides have 2n/ same variable with same number.
Answer: 15m
Step-by-step explanation:
Since 1cm is to 5m, just multiply 3 by 5 and you will get 15.
The total number of fish available in the tank is (18 + 22) = 40. We want to randomly select 2 fish and come up with 2 goldfish. The probability for 1 goldfish to be taken out would be 18/40.
Now, after drawing the first fish, the probability to get another goldfish would be 17/39. And the probability to draw 2 goldfish would be the product of both probabilities.
P = (18/40)(17/39) = 51/260
Thus, the answer is <span>B.</span>
