Components in exhaled and inhaled air​

Biology
1 answer:
umka21 [38]3 years ago
5 0

We inhale air that is comprised of roughly 78 percent nitrogen and 21 percent oxygen, as well as a trace amount of other gases.

When we exhale, the components are the same, they just come out in different amounts. Exhaled air is made up of about 78 percent nitrogen, 18 percent oxygen, and four percent carbon dioxide, excluding those trace gases.

TL;DR

Inhaled: 78% Nitrogen, 21% Oxygen, 1% Other Gases

Exhaled: 78% Nitrogen, 18% Oxygen 4% Carbon Dioxide

I need a argument to: An organism has two copies of a gene for each feature.
ExtremeBDS [4]

Answer:

Since genes come in more than one version, an organism can have two of the same alleles of a gene, or two different alleles. This is important because alleles can be dominant, recessive, or codominant to each other. I hope this helps

A population of 1,000 healthy, at risk people is monitored for one year starting on January 1st, and the development of cases of
masha68 [24]

Answer:

\mathbf{cummulative \ incidence = \dfrac{60}{1000}}

Explanation:

We recognize that total occurrence equals new cases of disease over time divided by the number of people at risk at the onset.

Mathematically:

\mathbf{cummulative \ incidence = \dfrac{New \ cases \ of \ disease \ occurrence}{Number  \ of \ population \ at \ risk \ at \ onset}}

Given that:

Number of the population at risk = 1000 individuals

New cases during Jan 1 - Dec 31 = 60 because;

At 20 occurred on June 30 & 40 on Sept. 30) & no new cases were identified after that:

∴

\mathbf{cummulative \ incidence = \dfrac{60}{1000}}

What are some possible future changes in the global climate?
Ugo [173]

The most probable future changes in the global climate are:

- Global warming;

If the levels of CO2 and methane increase enough in the atmosphere to be able to intensify the Greenhouse effect, than some portion of the ice on the planet will melt because of the rising temperatures, thus lifting up the sea level, creating more unpredictable weather with larger and stronger storms, but also making the mainland much drier. This would be a scenario if the continents are arranged like they are now, but if there isn't a sufficient mass of land on and around the poles, than all of the ice will melt and the sea levels will rise so much that the planet will come in the ''water planet'' scenario, and it will have wet tropical climate pretty much everywhere on the planet.

- Ice Age;

If there's a disruption in the warm ocean streams and some of them disappear, or the levels of nitrogen or oxygen increase in the atmosphere, the Earth will start to cool off, thus coming to a situation of an Ice Age. In this kind of situation, there will be large ice sheets on and around the poles that are stretching much further towards the lower latitudes, as well as mountains all over the world that are covered in snow and shaped by glaciers.

Wittaler [7]

Answer:

Carbohydrates, proteins, lipids and nucleic acids.

Explanation:

Biomolecules are organic and are carbon containing and are of four types which are carbohydrates, proteins, lipids and nucleic acids.

Carbohydrates are part of our major diets and are found in grains, fruits and vegetables and so on.

Carbohydrates are energy producing food through glucose.

Lipids contain both fat and oil and they are hydrocarbon and non polar molecules that don't dissolve in water. They provide energy, insulation in the environment and are major constituent of plasma.

Proteins are organic molecules found in meat, milk, beans, cheese e.t.c.

They are body building food or serve as building blocks.

They are enzymes and hormones which are involved in body mechanisms.

Nucleic acids are composed of deoxyribonucleic acid(DNA) and ribonucleic acids. They are the genetic constituent of living organisms and they carry the genetic information.
