The surface of the earth changes. Some changes are due to slow processes, such as erosion and weathering, and some changes are due to rapid processes, such as landslides, volcanic eruptions, and earthquakes.
Answer:
A: Mutations always decrease an organism's fitness.
Explanation:
Looking at the given options, the one that is false is option A because generally speaking, for a population whereby a trait is being exposed to stabilization of selection over time, the mean will certainly remain approximately the same.
We solve the problem using the Hardy-Wineberg equation.
Let us start with the homozygous dominant number of red toes trait,
∴ p² = = 0.4
We have the frequency for red toe trait as p = = 0.63
Solving for the frequency of white toe trait by using the fact that,
p + q = 1
∴ q = 1 - p = 1 - 0.63 = 0.37
Now we can calculate 2pq in p² + 2pq + q², which is the frequency for pink toes.
∴ 2pq = 2 x 0.63 x 0.37 = 0.47
Therefore, in a population of 1000 people, 47% have pink toes.
Hence 47% of 1000 will be 470.
The answer is 470.
The Fossil record is the history of life as documented by fossils, the remains or imprints of the organisms from earlier geological periods preserved in sedimentary rock.
