What is the name for the physical presentation of an organism's genes?

A. Phenotype

B. Species

C. Phylum

D. Genotype

Answer Explanation:

Phenotype is the physical presentation of an organism's genes. In other words, the phenotype is the physical characteristics of the organism. Phenotype is often contrasted with genotype, the genetic makeup of an organism. The genotype of the organism is not visible in its presentation, although some of the characteristics encoded in the genes have to do with physical presentation. A phylum is a group of classes that are closely related. A species is a group of like organisms that are capable of breeding together and producing similar offspring.

Therefore, the Correct Answer is A.

More Questions on TEAS 7 Science

  • Q #1: A chemistry experiment is performed to determine the effect of a nonvolatile solute on the boiling point of water. Three trials are performed in which 10 mg, 20 mg, and 30 mg of salt are added to 500 mL of distilled water. Each solution is heated on a hot plate, and the elevated boiling points are recorded. Determine the dependent and independent variables in this question.

    A. The independent variable is the amount of salt, and the dependent variable is the temperature at which the water boils.

    B. The independent variable is the amount of water, and the dependent variable is the temperature at which the water boils.

    C. The independent variable is the temperature at which the water boils, and the dependent variable is the amount of salt.

    D. The Independent variable is the amount of salt, and the dependent variable is the amount of water.

    Answer Explanation

    In a scientific experiment, the dependent variable is the condition that is being tested and measured. The independent variable is the condition that is being changed or controlled. In this example, the amount of salt is varied, and the boiling point of water is measured. Therefore, the independent variable is the amount of salt, and the dependent variable is the temperature at which the water bolls.

  • Q #2: Where is the gastrocnemius vein in relation to the femoral vein?

    A. Lateral

    B. Distal

    C. Superior

    D. Ventral

    Answer Explanation

    The gastrocnemius vein is found in the calf. The femoral vein is found in the proximal anterior thighs/pelvis.

    Since the gastrocnemius vein is found below the femoral vein it is distal or inferior to the femoral vessel.

  • Q #3: A group of researchers have conducted a study examining the impact of a new medication on blood pressure. What is the purpose of submitting the study for publication in a peer-reviewed journal?

    A. Other scientists can validate or disprove the findings.

    B. Publication in a peer-reviewed journal will guarantee acceptance of the study's conclusions.

    C. Publication in a peer-reviewed journal is unnecessary for this type of study.

    D. Publication in a peer-reviewed journal will lead to the manipulation of the study's results.

    Answer Explanation

    Other scientists can validate or disprove the findings.

    The purpose of submitting a study for publication in a peer-reviewed journal is to have the study’s methodology, results, and conclusions evaluated by other experts in the field.

    This process helps to ensure the quality and validity of the research. Choice B.

    Publication in a peer-reviewed journal will guarantee acceptance of the study’s conclusions is incorrect because publication in a peer-reviewed journal does not guarantee acceptance of the study’s conclusions.

    The study’s findings may still be subject to debate and further research. Choice C.

    Publication in a peer-reviewed journal is unnecessary for this type of study is incorrect because publication in a peer-reviewed journal is an important step in the scientific process for all types of studies.

    Choice D.

    Publication in a peer-reviewed journal will lead to the manipulation of the study’s results is incorrect because the peer-review process is designed to prevent manipulation of results by ensuring that the study meets rigorous standards for quality and validity.
