Overfishing occurs when more fish are removed from an ecosystem than can be maintained by the population,
Overfishing can lead to significant population declines in economically important species. The passage describes
additional impacts of overfishing on populations.

According to the passage, which mechanism explains the observed changes in fish size over time?
A. Smaller fish produce fewer eggs than larger fish do, so they contribute fewer offspring to the next
generation.
B. Fish that are small enough to escape fishing nets are more likely to survive than larger fish.
C. Scientists found that Atlantic silversides exhibited changes in feeding and foraging rates after four
generations of selection,
D. The average size of pink salmon returning to spawn decreased from 6.0 pounds to approximately 4.5
pounds.
Answer:
Step-by-step explanation:
a) One can get maximum score when all the 20 questions answered are correct.
Maximum score = 20*3 = 60 points
b) Minimum score = 20 * (-2) = -40 points
c) Points for correctly answered questions = 10*3 = 30
Incorrectly answered questions = 14 - 10 = 4
Points for incorrectly answered questions = 4 * (-2) = -8
Total score = 30 + (-8) = 22
d) Points for correctly answered questions =5*3 = 15
Points for incorrectly answered questions = 13 * (-2) = -26
Total score = 15 + (-26) = -11
2x+4 is the length of one side
Answer:
n + (n + 6) = 24.
Step-by-step explanation:
Let him have n blue marbles, then he has n + 6 other narbles.
He has a total of 24 marbles, so:
n + (n + 6) = 24.
Answer:
option f is right
Step-by-step explanation:
Given that data is collected to perform the following hypothesis test.
(right tailed test)
Sample mean = 5.4
p value = 0.1034
when p value = 0.1034 we normally accept null hypothesis. i.e chances of null hypothesis true is the probability of obtaining test results at least as extreme as the results actually observed during the test, assuming that the null hypothesis is correct
f) If the mean µ does not differ significantly from 5.5 (that is, if the null hypothesis is true), then the probability of obtaining a sample mean y as far or farther from 5.5 than 5.4 is .1034.
