How do the alveoli in the lungs move oxygen and nutrients into the bloodstream? 1.Gravity 4.Time 2.Diffusion 5.Pressure 3.Magnetic force

Answers

Answer 1

Answer:

2.Diffusion

Explanation:

As we metabolize certain nutrients for the correct functioning of our cells, carbon dioxide is produced as a result. We need oxygen in order to metabolize them, so we need to have a system to incorporate it, and to eliminate the carbon dioxide produced.

This system is provided by the interaction between the respiratory system, which allows the enter of oxygen into the body and gets rid of the carbon dioxide, and the circulatory system, which acts transporting carbon dioxide and oxygen to and from the lungs, respectively.

The surface available for the gaseous exchange is enlarged by the pulmonary alveoli. The alveoli are the terminal aerial spaces of the respiratory system and the structures where the exchange between the air and blood is produced. Each alveolus is surrounded by a net of capillaries, where oxygen is freed from the hemoglobin and moves into the cells by diffusion. Carbon dioxide, diffuses out of the cells into the capillaries, where most of it dissolves in the plasma of the blood.

Is it OK for people to post fake vacation pics and other fake info on social media? Why or why not? Use facts and details from the Article to back up your answer.

Answers

Answer:

No, It is not okay to pretend on social media.

Explanation:

No, it is not okay for people to post fake vacation pics and other fake info on social media. This is very wrong, as -

This 'all time look good, feel good, have a happening life' approach of social media - implies showing only the positive side & not negative side of people's life. However, in real life is not a bed of roses. Faking things out implies that pretending to be cool has become more important than sharing deep meaningful relationships, & highlights  superficial desire of false popularity. It is also harmful to people being communicated this fake image, as they might indulge into any social involvement, on the basis of unreal image of the concerned person.

How many moles of acetaminophen are in a 0.8mL (0.0008L) dose of infants Tylenol

Answers

Answer:

0.007 mol

Explanation:

Step 1: Given data

Volume of acetaminophen: 0.8 mL

Step 2: Calculate the mass corresponding to 0.8 mL of acetaminophen

The density of acetaminophen is 1.26 g/mL.

0.8 mL × (1.26 g/mL) = 1 g

Step 3: Calculate the number of moles corresponding to 1 g of acetaminophen

The molar mass of acetaminophen is 151.16 g/mol.

1 g × (1 mol/151.16 g) = 0.007 mol

What are glasses ?

Glasses are visual eyewear that have lenses fixed in a frame that holds them in front of a person's eyes. The frame often has a bridge over the nose and arms that rest over the ears. Glasses are also known as eyeglasses or spectacles.

The term "glasses" likely originated from the word "spyglass," which was originally used to describe "a pair of eyeglasses" that had to be held up to the eyes in order to be fully effective.

Eyeglasses, often known as glasses or spectacles, are lenses that are mounted in frames and worn in front of the eyes to improve vision or to correct astigmatism, myopia, or hyperopia.

Thus,  Josh could dry them with a towel to keep the glasses from being slippery.
