A hypothesis is an expectation of what you are going to investigate. So B and D are canceled C has nothing to do with climate So the only remaining answer is A
Mutation- a permanent change in the DNA sequence that makes up a gene.
<span>This kind of relationship is called mutualism and is defined by both parties being equally beneficial to each others survival. An example of this kind of relationship is found a lot in nature, as with the relationship between fish and coral reefs in the sea. Corals provide shelter and protection for the small fish while the fish in return also provide protection from algae and seaweed invading in on their space and killing off the coral.</span>
Special cells in the skin<span>, called melanocytes, make two different types of melanin, eumelanin and pheomelanin. ... Melanin helps </span>protect our skin<span> and hair by filtering out potentially harmful ultraviolet (UV) radiation from the </span>sun. The UV light from thesun<span> can </span>damage DNA<span> and cause cancer</span>
Answer:
E
Explanation:
A mutation that confers phenotypic benefits to individuals or a group of individuals would be considered a beneficial mutation.
<em>Mutation involves a sudden change to the gene coding sequence of the DNA. It can occur as a result of substitution, duplication, deletion, inversion, insertion, etc of purine or pyrimidine bases of the DNA.</em>
<u>These changes can be harmful, beneficial, or neutral to individuals. Those that have neutral effects in individuals are also called silent mutations.</u>
In the case of a duplication causing trichomatic vision in humans, it represents a form of beneficial mutation because it enables humans to be able to distinguish between red, green, and blue colors. The ability to distinguish among these colors improves the quality of life of humans.
