Answer:

The correct answer is option C. "The magnetic field of earth keeps changing because of the suns activity"

Explanation:

The magnetic field of Earth is not a steady force, and is affected by external forces such as the suns activity, particularly during strong solar/geomagnetic storms. The changes in the magnetic field of Earth explains why the auroras Are sometimes seen at northern Ohio. The auroras are created by energetic electrically charged particles accelerating along the magnetic field, if the location of the magnetic filed changes, the location of the auroras change as well.

12. Which of the following information is given to participants in clinical trials as part of obtaining informed consent?
quester [9]

The correct answer is B. Possible side effects of a new medical treatment or product.

Explanation

A side effect is a concept that refers to the effect that a drug or treatment produces on the patient. Generally, when a drug is produced, a clinical trial is necessary to prove its effectiveness. This requires the participation of several volunteers who will test the drug and verify its effectiveness. However, these clinical trials have risks for volunteers since they can bring them negative effects because they are going to test drugs that have never been used before, so they must give their consent through a document called "informed consent. "where the volunteer is informed about the possible risks that the clinical study may have on him and if he is willing to undergo the test. Therefore, one of the main topics discussed during an informed consent is the possible side effects that the clinical study can bring to inform the volunteer of these conditions and confirm that he agrees with them. Therefore, the correct answer is B. Possible side effects of a new medical treatment or product

Genes in eukaryotes (check all that apply): Group of answer choices Represent a locatable region of genomic sequence, correspond
ziro4ka [17]

Answer:

1. A locatable region of genomic sequence, corresponding to a unit of inheritance which is associated with regulatory regions, transcribed regions, and/or other functional sequence regions.

2. Were historically defined as the unit of hereditary material that causes a phenotype.

3. May be composed of a union of genomic sequences encoding a coherent set of potentially overlapping functional products.

Explanation:

A gene is a sequence of nucleotide present on a chromosome which determines a trait of an organism.  The gene term was provided by the Wilhelm Johannsen in 1909 to refer to the hereditary unit of the organisms.

The genes in eukaryotes are not necessary that they will code for the protein as there are some RNA molecules which are not translated into the protein like rRNA and tRNA molecules.

The sequence of a gene in eukaryotes is a union of the regulatory of the functional and transcribed genes.

Thus, the selected option is correct.
