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:

Water is transported from one area to another area that has little water. Water is collected and salt allowed to settle at the bottom.

Explanation:

Desalination of water is a process of the removal of salts and minerals from the water. This process is used for the production of water suitable for human consumption or irrigation.

Natural desalination occurs trough the hydrologic cycle when seawater evaporates. On the other hand, manipulated desalinization is an energy expensive alternative to natural desalination.

Which RNA molecule is involved in translating a short sequence of RNA into an amino acid, acting like a molecular Rosetta stone?

oee [108]

Given what we know about the translation process, we can confirm that the RNA in question that aids in the process of translating a short sequence of RNA into an amino acid is mRNA.

mRNA is referred to as messenger RNA. This RNA molecule acts as just that, a messenger carrying the necessary code to create amino acids and therefore, proteins. This messenger binds itself to the ribosomes of a cell, which are in charge of reading the code, one codon at a time, and chaining together the corresponding amino acids.

Taylor and her husband Tyler just had a baby at the hospital. They believe the hospital has switched their baby. Taylor is type

Natalija [7]

Answer:

The DNA of the baby shares the DNA of both father and mother, and hence a cross link between an O type mother (Taylor) and an AB type father (Tyler) will produce children with blood groups A and B. It will be impossible to give birth to a child with blood group O.
