Answer:protection from other predators.
Explanation: the quills will stick into a predator that attack the porcupine Note: it does NOT shoot its quills
The correct answer is: Hares with a mutation that causes them to change color in response to temperature rather than day length
Since the climate is changing (as a consequence of global warming) temperatures are increasing more and more through the years. These changes affect populations, so they need to adapt to new environment conditions in order to survive. In this example above, mutations within snowshoe hares that will help them to change color in response to temperature rather than day length is very advantageous. Hares will be brown more often, because there are less and less colder temperatures and snow.
Answer:
The answer to your question is below
Explanation:
Because similar to living things, some rocks are formed and it takes a long period to degrade them. During this period new rocks are born, some of these rocks can react with some compounds of the environment and can form new rocks or can be degraded.
What I try to say is that rock formation takes a lot of time and while some rocks disappear new rocks are created.
<span>The movement of alleles from one population to another is called gene flow. Other alleles will likely increase in frequency and become fixed. These changes in allele frequencies that are due to chance are called genetic drift. Genetic drift causes a loss of genetic diversity in a population.</span>
