C because the moon has less mass than Earth the Gravitational Force is less and thus anything on the moon weighs less than on Earth
Lasting genetic similarities make the two bears biological sister species, more closely related to one another than to any others. ... But Ursus maritimus has also evolved to match its polar environment, growing a longer snout than brown bears' and larger, paddle-like paws, both of which aid polar bears in hunting seals.
Answer/Explanation:
Pollution during the industrial revolution caused trees to become covered with soot, making them darker. This dark appearance meant that the peppered moth, which usually had a light colour, was clearly visible against the tree. This meant it was easier for predators to identify. As a result, their numbers decreased because they were an easier target.
However, there was also a rarer form of the moth, which was dark in colour. These were initially very rare. However, because of the change in the tree colour owing to the industrial revolution, these moths were better suited to the environment, as they were more camouflaged against the dark tree. This meant it was easier for them to avoid predators, and so they were more likely to survive to reproductive age and pass on the genes that produce the dark colour. This meant that the dark moths increased in number.
Answer:
The correct answer is - 4 and 7 chromosomes in each cell.
Explanation:
Meiosis is the cell division in which one parent cell produces four daughter cells with a half number of the chromosome than parent cells.
According to the question oak cell performed meiosis which is reduction division so the number of cell will be four and 7 chromosome will be present in each daughter oak cell.
Thus, the correct answer is - 4 and 7 number of chromosome in each.
If these are your choices:
A. Warm water increases the speed of sound.
B. Cold water increases the speed of sound.
C. High water pressure decreases the speed of sound.
D. Low water pressure increases the speed of sound.
The answer is B. because warmer particles rises which is less dense than the cooler particles. Sound waves travels faster in a denser medium making statement B as the correct answer.
