Which of the following statements regarding oxygenation and ventilation is correct? Select one: a. Oxygenation is the movement o

f air into and out of the lungs, whereas ventilation is the exchange of gases. b. Oxygenation without adequate ventilation can occur in climbers who quickly ascend to an altitude of lower atmospheric pressure. c. In mines or confined places, where oxygen levels have been depleted, ventilation may occur. d. In carbon monoxide (CO) poisoning, ventilation is impaired because CO binds to oxygen very quickly

Answer:

c. In mines or confined places, where oxygen levels have been depleted, ventilation may occur.

Explanation:

Environments classified as “confined space” are hazardous for several reasons, but one of the main ones is the low oxygen concentration. Normally atmospheric air contains a 21% concentration of oxygen that is necessary for the maintenance of human life. Some confined spaces have this concentration of less than 21% oxygen, which can be very harmful to human life and lead to death.

Low oxygen concentration can be masked by ventilation in confined places. This is because in confined places oxygen levels may be low, but ventilation may continue despite inadequate oxygenation.

Frogs go through metamorphosis.<br> a. True<br> b. False
Nimfa-mama [501]
That statement is true. When a frog hatches from the egg, a fish like creature called a tadpole emerges. As the tadpole grow, lungs and legs grow, and the gills and tail "absorb," into the body. After that, the now frog creatures spends most time on land. Hope that helped! Vote this as the brainliest answer please!

Describe the Real world examples of newtons third law that were intended in applications of newtons law
AlexFokin [52]

Answer:

  1. The recoil force of a bazooka (reaction) + the accelerating force of a missile
  2. When walking, the foot pushes down and back (action) + the floor pushes up and forward
  3. When a rocket is taking off, the combustion of the fuels (an action) creates a direct and opposite reaction which is the thrust of the rocket upwards.

Explanation:

Newton's third law states that for every action (force) in nature there is an equal and opposite reaction. Simply put, forces act in approximately equal and opposite pairs (Action and Reaction).

This law is one of the reasons why the foundation of a building must be built in such as way that is exerting equal and opposite pressure against the building which it is carrying. When the forces are equal, the balance of forces are said to be in equilibrium.

Cheers!

The climate of Houston, Texas is humid subtropical, with a temperature
Talja [164]

The culprit is an "arctic outbreak" that originated just above the US-Canada border, which is freezing temperatures across much of the US territory.

<h3>Arctic outbreak</h3>

"Bursts" of cold air like this are usually confined to the Arctic region thanks to a series of low-pressure systems, says the NWS. However, one of these waves advanced through Canada and "escaped" to the US.

According to experts heard by Reuters, it is a vast mass of icy air in the atmosphere, which brings with it frigid temperatures - which can be prolonged if storms form.

From this information we can conclude that according to the US Weather Service (NWS), the culprit is an "arctic outbreak" that originated just above the US-Canada border, which is freezing temperatures across much of the US territory.
