The correct answer is: A. A change in a cell's genetic material.
Mutations occur in DNA as a result of mistakes during the DNA replication (when repair mechanisms don’t fix it) or as the result of environmental factors (e.g. UV light). Mutations can have positive impact, by increasing the genetic variation or can have negative effect, causing the diseases or cancer.
Answer:
A gyre is a large system of rotating ocean currents.
Together, these larger and more permanent currents make up the systems of currents known as gyres.
Explanation:
Answer:deoxyribose
Explanation: From the information provided, (though the diagram is not shown), the structure is a DNA double helix. A DNA contains deoxyribose sugar thus the name deoxyribonucleic acid. RNAs contains ribose sugar thus the name ribonucleic acid. A deoxyribose is a pentose (a 5- carbon sugar) which lacks one oxygen atom at position two of its carbon skeleton, hence the name deoxy - ribose. It's usually written chemically as 2- deoxyribose.
Symbiotic relationship is the relationship that the organisms in the ecosystem have. This is their way of interaction. Every organism has different interaction with the other. Based on the organisms given above which are the pistol shrimp and the gobies, being dependent on each other for shelter and protection shows the relationship of mutualism. This means that both benefit on each other.
