A. digestion

B. ingestion

C. elimination

D. absorption

Answer Explanation:

Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma.

  • Q #1: The ________ circulation picks up oxygen for cellular use and drops off carbon dioxide for removal from the body.

    A. pulmonary

    B. interlobular

    C. respiratory

    D. bronchial

    Answer Explanation

    Our blood flow is separated into two major pathways, listed below:

    1. Systemic circulation - this comes from the left side of the heart and pumps blood to all working tissues, including the brain, muscle, heart, and other organs, and then into the right side of the heart.
    2. Pulmonary system - this comes from the right side of the heart, and pumps blood to the alveolar sacs within the lungs, and then into the left side of the heart

    In pulmonary circulation: The pulmonary artery is a big artery that comes from the heart. It splits into two main branches, and brings blood from the heart to the lungs. At the lungs, the blood picks up oxygen and drops off carbon dioxide.

  • Q #2: Which of these infectious agents do not have nucleic acid?

    A. viroids

    B. viruses

    C. bacteria

    D. prions

    Answer Explanation

  • Q #3: Which of the following is the atomic number of an atom that has 12 protons and 12 neutrons?

    A. 144

    B. 12

    C. 24

    D. 1

    Answer Explanation

    elements are arranged on the periodic table based on their atomic number. This identity is critical in evaluating the chemical families of elements in chemistry. Atoms are made of protons, neutrons, and electrons. Protons and neutrons are found in the nucleus while electrons are found outside the nucleus of the atom. It is the number of protons of an atom that gives its atomic number. Therefore, an atom with 12 protons has an atomic number of 12.

  • Q #4: If a portion of strand of DNA bases reads 5’ AGCTAGCGT 3’, what would the sequence of bases on the complementary strand read?

    A. 5’ UCGAUCGCA 3’

    B. 3’ TCGATCGCA 5’

    C. 5’ TCGUTCGCU 3’

    D. 3’ AGCTAGCGT 5’

    Answer Explanation

    The complimentary base pairing of DNA states that A pairs with T while C pairs with G. From the give sequence, the complimentary DNA strand will be 3’ TCGATCGCA 5’

  • Q #5: A myocardial infarction affects which of the following blood vessels of the heart?

    A. Aorta

    B. Vena cava

    C. Pulmonary

    D. Coronary

    Answer Explanation

    A myocardial infarction refers to heart attack, which result from blockage of blood flowing into the heart.

    Blocking is caused by the deposition of fat or cholesterol that forms plaque on the surface of coronary arteries, which supply blood to the heart.

  • Q #10: Which of the following processes does atmospheric pressure play a role in?

    A. Pulmonary Ventilation

    B. Photosynthesis

    C. Osmosis

    D. Evaporation

    Answer Explanation

    Among the choices provided, only one process is directly influenced by atmospheric pressure:

    Pulmonary Ventilation (Correct): Pulmonary ventilation, also known as breathing, is driven by pressure differences between the lungs and the atmosphere. Atmospheric pressure plays a pivotal role in this process by facilitating the movement of air into and out of the lungs.

    The other options mentioned in the choices—Photosynthesis, Osmosis, and Evaporation—are not primarily influenced by atmospheric pressure. While atmospheric pressure can indirectly affect certain aspects of these processes, it is not a dominant factor in their mechanisms.
