Hi there!
The best possible scenario for the giraffes with longer necks to survive would be one in which all the lower leaves somehow disappear! This would mean only giraffes with longer necks can eat therefore those will have a better chance of surviving. Luckily the answer that fits that perfectly would be...
D. Monkeys swarm in and tear off all of the lower leaves to use for shelters.
They undergone genetic mutation that influenced their fur color.
Mutations result either from accidents during the normal chemical transactions of DNA, often during replication, or from exposure to high-energy electromagnetic radiation (e.g., ultraviolet light or X-rays) or particle radiation or to highly reactive chemicals in the environment. Mutation can be of 4 types Germline mutations occur in gametes. Somatic mutations occur in other body cells. Chromosomal alterations are mutations that change chromosome structure. Point mutations change a single nucleotide. Frameshift mutations are additions or deletions of nucleotides that cause a shift in the reading frame. Factor that influenced mutation are the size of the gene, its base composition, its position in the genome, and whether or not it is being actively transcribed influence its mutation rate.

I believe that the answer to your question would be A. Heart Begins.
Answer:
1.Earth
2.tidally
3.spin
4.Kuiper
5.A solar nebula forms when the gas and dust are pulled together in a spinning disk. Particles began to clump together due to gravity, and larger chunks of material exert more gravity on nearby dust and gas. These chunks of material grew faster and formed planets or moons. Denser elements such as iron settled closer to the center of the solar nebula.
Explanation:
this is for penn foster
It is d. If it was adaptation, the organism would have stayed in order to adapt. The species moved in order to not go extinct. It can not be speciation, because a new species was not made. It is stimulus. It experienced too much heat, so it left.
