Which of the following statements is true concerning oxygen at high altitudes?
The partial pressure of oxygen is higher.
The partial pressure of oxygen is lower.
Oxygen makes up a smaller percentage of the air.
Oxygen makes up a larger percentage of the air.
Homework Answers
Oxygen is a vital element for all the living things to survive in the world. Oxygen is represented with a symbol O2 oxygen element with two molecules. Oxygen available in atmospheric pressure Fio2 is 21%. Trees during respiration they produce more oxygen by utilizing carbon dioxide for the respiration process. In humans respiration is a process in which oxygen is breath in and carbon dioxide is released out. Any respiratory disorders leads to oxygen insufficiency.
The partial pressure of oxygen level in high altitudes is lower as there is a marked decrease in atmospheric pressure.It results in decreased driving force and inability of the lungs to push oxygebln into the vital circulation.
The other options of
Oxygen makes up a smaller percentage of the air.
Oxygen makes up a larger percentage of the air.
Is incorrect as oxygen availability in the atmospheric air 21% irrespective of the altitude.

The partial pressure of oxygen in the lung alveoli is a bit lower than in ambient...
The partial pressure of oxygen in the lung alveoli is a bit lower than in ambient air, being about 100 mm of mercury, or 0.13 Atm (it is lower than the partial pressure in air mainly because oxygen is continually taken up by the alveolar capillaries and carbon dioxide is continually released into the alveoli). In cell-free blood plasma (or a saline solution formulated to match key characteristics of blood plasma), which lacks red blood cells and therefore lacks hemoglobin,...

Which of the following statements concerning the Bohr effect are true. Lowering the pH shifts the oxygen dissociation curve for hemoglobin to the right The acidic environment of an exercising muscle allows hemoglobin to bind O_2 more tightly The affinity of hemoglobin for O_2 is diminished by high concentrations of CO_2 In the lungs, the presence of higher concentrations of H^+ and CO_2 allows hemoglobin to become oxygenated In the lung, the presence of higher concentrations of O_2 promotes the...
Which of the following statements is TRUE?
Which of the following statements is TRUE? A) The higher the temperature, the lower the average kinetic energy of the sampleB) At low temperatures, intermolecular forces become important and the pressure of a gas will be lower than predicted by the ideal gas law. C) The smaller a gas particle, the slower it will effuse D) At a given temperature, lighter gas particles travel more slowly than heavier gas particles.

Question 6 (1 point) Which of the following statements are accurate? Oxygen is not the most abundant gas in the atmosphere. Diffusion of gases is 'better' across single cells that are thin than layers of thin cells. Gas exchange in humans occurs in the lungs at the structures called alveoli. Diffusion of gas occurs from areas with a higher partial pressure to an area of lower partial pressure. Organisms with gills may use a countercurrent exchange mechanisms to extract more...

Decide which of the following statements are true and which are false.
Decide which of the following statements are true and which are false. At constant temperature, the lighter the gas molecules, the larger the average kinetic energy. Real gas molecules behave most ideally at low temperature and high pressure. As temperature decreases, the average kinetic energy of a sample of gas molecules increases In order for two separate 1.0 L samples of O2(g) and H2(g) to have the same average velocity, the H2(g) sample must be at a higher temperature than the O2(g) sample At constant...

Define partial pressure. What is the partial pressure of oxygen (PO2) in the outside air, in the alveoli, in the pulmonary vein, and after the tissue (i.e. muscle)? What is the cause of the drop on PO2 at each of these places? What is the partial pressure of CO2 (PCO2) in the arterial blood after an exhalation and then after the muscles? What causes the PCO2 to go up from the lungs to after the muscles?
