Answer:
Evolution.
Explanation:
A small portion of the moth population began going to a different type of tree within the same forest to breed instead of the older one because of the evolution. Due to this evolution, the moth is able to breed on another tree. The characteristics of some moth specie changed over several generations due to may be change in their genetic makeup so we can say that it is because of evolution.

Volcanic eruptions occur when magma rises upwards through ___ to reach the ____
Volcanoes eruption when molten rock called magma rises to the surface. Magma is formed when the earth's mantle melts.
When Melting takes place?Melting may happen where tectonic plates are pulling apart or where one plate is pushed down under another. Volcanoes are the large volcanic buildings with long, and generally the conical shape, usually with a small crater on the summit and the steep flanks, that constructed by the interleaving of lava flows and the pyroclastic products emitted by one or more conduits.
Compound volcanoes are present in all regions of the volcanism, but it has in the plate convergence zones, where the tectonic plate subdows plunges toward the earth's mantle beneath another tectonic plate, that these volcanic buildings are the most abundant.
The magmatic expression of a converging plate margin environment is usually a series of sub-regularly spaced Compound Volcanoes, forming a sub-parallel volcanic arch to the tectonic fossa.

4. If a mutation blocked the function of the signal recognition particle, making it unable to bind signal sequence, what would result
Answer:
All proteins would be translated in the cytoplasm
Explanation:
The signal recognition particle (SRP) is a cytoplasmic RNA-protein (ribonucleoprotein) complex whose primary role is to target signal peptide‐bearing proteins to the plasma membrane in prokaryotes and to the endoplasmic reticulum in eukaryotes. In eukaryotic organisms, SRP binds to the signal sequence of the protein when the growing polypeptide chain emerges from the ribosome in the cytoplasm. This binding is key because it results in a slowing of translation, a mechanism known as elongation arrest. Therefore, without a functional SRP, elongation arrest would not occur and proteins would be translated on free ribosomes in the cytoplasm.

How do the hypotheses of ""phyletic gradualism"" and ""punctuated balance"" explain the process of lineage diversification?
Answer and Explanation:
Phyletic gradualism and punctuated balance are speciation theory. They are effective models for understanding macroevolution. Both define the rates of speciation. The phyletic gradualism model theorizes that most speciation is gradual, slow, and uniform, such as a black and yellow butterfly. When a butterfly is born, its color is yellow and orange, making it hard to see. The black and yellow butterflies become extinct over a long period, while yellow and orange butterflies can survive due to less visibility to predators. Punctuated balance suggests that once a species seems in the fossil record, the population will become steady and indicate little evolutionary modification, such as a species of birds live in stasis for numerous years. Suddenly bacteria affect their prime tree of shielding to die. The birds must adopt the changes. Some birds survive, and the remaining birds die. Until the others die out, more birds are born. Then the species again returns to a stasis state. The Gradualism model shows evolution as a slow, steady process in which organisms develop and change slowly over time, while punctuated balance models show evolution as a long period of evolutionary change. Due to the mechanisms of evolution in a time frame, both models describe successive evolutionary alterations.

A scan of Sam's genome for the 100 most common mutations known to cause RP didn't find anything. How can you explain this result?
Answer:
He is either not carrying the gene for RP or the RP gene has mutated.
Explanation:
RP or Retina Pigmentosa is an eye defect inherited by a person from a parent. The disease is degenerative as the individual gradually loses his sight. It normally starts off as night-blindness and could go as bad as a total loss of sight.
The mutation of both the RPGR and RP2 genes which are responsible for the function and structure of light-reception in the eye accounts for most cases of Retina Pigmentosa disease.
