True / False: Taking a faster, deeper breath which allows you to move a greater volume of air into the lungs is due to a smaller

negative intrapulmonic pressure created versus taking a slower, shallower breath (select one word answer only please).

Answer:

False

Explanation:

Intrapulmonary pressure, is known referred to as alveolar pressure. It is the pressure within the lung. When the glottis is not closed, the alveolar pressure is seen to be equal to the pleural pressure (the negative suction pressure that occurs between the thin layers of pleura) since no air is flowing into the lungs.

It is important to note that rapid and larger changes in lung volume will lead to a larger, positive intrapulmonic pressure changes.

For fertilization to occur in humans, only one sperm is needed to weaken the barrier that surrounds the egg.
photoshop1234 [79]

Answer:

False

Explanation:

Approximately 200 out of 200 million sperms ejaculated during intercourse reach the general vicinity of the egg.  They sperms must undergo capacitation during which dilute inhibitory factors fluids of the female reproductive tract weaken the membrane of the sperm head so that head of the sperm can be broken easily when it came in contact with the egg.

The first sperm to reach an egg isn’t the one to fertilize it because the egg is surrounded by a gelatinous membrane called the zona pellucida. Outside this layer, a layer of small granulosa cells also present.

Therefore, it requires numerous sperm to clear a path through these barriers before one of them can penetrate the egg and fertilize it.

Anit [1.1K]

Answer:

No

Explanation:

Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.

Why do some small bridges have weight limits that depend on how many wheels or axles the crossing vehicle has?
Sladkaya [172]
Well you know sometimes you see a lot of small bridges that will have weight limit signs. I believe this is really for safety precautions. Keyword: SMALL bridge -

Due to some bridges being small, the materials and strength of the bridge may not can withstand a certain weight. The contents of the vehicle, axels, and wheels, all add to that weight. So there is a very good reason for that to matter.
I hope my somewhat, tied together answer provides just the information you need!
