Which of the following vessels carries oxygenated blood?  

A. Superior vena cava

B. Inferior vena cava.

C. Pulmonary artery

D. Pulmonary vein

Answer Explanation:

The pulmonary veins are the vessels that carry oxygenated blood from the lungs to the left atrium of the heart.

 

Choice A is not correct because the superior vena cava carries deoxygenated blood from the upper body to the right atrium of the heart.

Choice B is not correct because the inferior vena cava carries deoxygenated blood from the lower body to the right atrium of the heart.

Choice C is not correct because the pulmonary artery carries deoxygenated blood from the right ventricle of the heart to the lungs.

Therefore, the Correct Answer is D.

  • Q #1: Stimulus: 1of 1. A group of students performed an experiment to test terminal velocity, which is the greatest speed obtained by a falling object. The students dropped different numbers of coffee filters and measured the resulting terminal velocity. Which of the following conclusions is supported by the data in the following data table? #OF FILTERS MASS (g) TERMINAL VELOCITY (m/s) 1 1.01 1.74 2 1.99 2.48 3 3.02 3.04 4 4.0 3.50 5 5.01 3.80  

    A. Terminal velocity is when the force of gravity is equal to air resistance.

    B. Heavier objects take more time to reach terminal velocity.

    C. Heavier objects fall faster than lighter objects.

    D. The greater the number of filters, the smaller the terminal velocity.

    Answer Explanation

    Heavier objects fall faster than lighter objects.

    The data in the table shows that as the number of filters (and therefore the mass) increases, the terminal velocity also increases.

    This means that the heavier objects (with more filters) are falling faster than the lighter objects (with fewer filters).

    Choice A is not supported by the data in the table as much as it is true.

    Terminal velocity is indeed when the force of gravity is equal to air resistance, but this definition does not provide any information about the relationship between mass and terminal velocity.

    Choice B is also not supported by the data in the table.

    The data does not provide any information about the time it takes for an object to reach terminal velocity.

    Choice D is not supported by the data in the table.

    The data shows that as the number of filters increases, the terminal velocity also increases.

    This means that the greater the number of filters, the greater (not smaller) the terminal velocity.  

  • Q #2: Which of the following physiological responses is caused by the release of antidiuretic hormone?

    A. Increase in the concentration of calcium in the glomerulus.

    B. Increase in water reabsorption in the collecting duct

    C. Decrease in the concentration of calcium in the glomerulus.

    D. Decrease in water reabsorption in the collecting duct

    Answer Explanation

    Antidiuretic hormone (ADH), also known as vasopressin, is a hormone that helps regulate the amount of water in your body.

    It works to control the amount of water your kidneys reabsorb as they filter out waste from your blood.

     

    Choice A is not correct because an increase in the concentration of calcium in the glomerulus is not a physiological response caused by the release of antidiuretic hormone.

    Choice C is not correct because a decrease in the concentration of calcium in the glomerulus is not a physiological response caused by the release of antidiuretic hormone.

    Choice D is not correct because a decrease in water reabsorption in the collecting duct is not a physiological response caused by the release of antidiuretic hormone.

     

  • Q #3: In a phase diagram, which of the following is the term used for a substance held at a temperature and pressure where the solid, liquid, and gaseous states of a substance exist simultaneously?    

    A. Triple point

    B. Critical temperature

    C. Critical point

    D. Absolute zero

    Answer Explanation

    Triple point.

    In a phase diagram, the term used for a substance held at a temperature and pressure where the solid, liquid, and gaseous states of a substance exist simultaneously is the triple point.

    The triple point is a unique point on a phase diagram where the three states of matter (solid, liquid, and gas) can coexist in equilibrium.

    At the triple point, the temperature and pressure of the substance are fixed.

    Option B, critical temperature, is the temperature at which a gas cannot be liquefied, regardless of the pressure applied.

    It is a characteristic property of a substance and is typically higher than the boiling point of the liquid at standard pressure.

    Option C, critical point, is the point on a phase diagram where the liquid and gas phases of a substance become indistinguishable.

    At the critical point, the distinction between the liquid and gas phases disappears, and the substance becomes a supercritical fluid.

    Option D, absolute zero, is the theoretical temperature at which all matter has zero thermal energy.

    At absolute zero, all substances are in their solid state, but it is not relevant to a phase diagram, as it is a temperature where no transitions between states occur.

    In summary, the term used for a substance held at a temperature and pressure where the solid, liquid, and gaseous states of a substance exist simultaneously in a phase diagram is the triple point, whereas the other options provided are not relevant or are characteristic properties of substances in different contexts.
