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.

Therefore, the Correct Answer is A.

  • Q #1: Punnett square In a certain plant, red flowers are dominant over white flowers. A plant heterozygous for red flowers and a plant with white flowers are crossed. Which of the following is the expected proportion of phenotypes in the next generation?

    A. 4 red, 0 white

    B. 2 red, 2 white

    C. 1 red, 3 white

    D. 3 red, 1 white

    Answer Explanation

    We use the Punnet square to find the population of the resulting offspring from the crossing of a plant heterozygous for red flowers with a plant with white flowers.

    Let R be the dominant allele for red while r is the recessive allele color for red. Therefore, the phenotype for parent 1 which is heterozygous for red flower will be Rr and the second parent with white flowers will be rr.

    We cross the two phenotypes in a Punnet square as follows

     

    r

    r

    R

    Rr

    Rr

    r

    rr

    rr

     

    Thus, there are 2 heterozygous offspring with red flowers and 2 offspring with white flowers.

  • Q #2: 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 #3: Pathogens Which of the following microorganisms lack their own metabolic pathways and can only reproduce inside of a host cell?

    A. Bacteria

    B. Viruses

    C. Helminths

    D. Protozoa

    Answer Explanation

    The disease-causing microorganisms are known as pathogens, which include bacteria, fungi, protozoa, worms, viruses and prions. These organisms have distinguishing cell structures from each other. The most notable difference between viruses and other pathogens is that viruses lack a metabolism mechanism of their own and ability to produce proteins encoded by their DNA or RNA. However, they viruses rely on machinery of the host cell to produce their proteins and replicate their genomes.
