it is true that to test the smell of a substance, partially fill your lungs with air and, while standing slightly back from the fumes, use your hand to waft the odors gently toward your nose.

<h3>What is the odor?</h3>

An odor basically caused by one or more volatilized chemical compounds, which are generally found in low concentrations and can be detected by humans and animals using their sense of smell.

An odor is also known as a "smell" or a "scent," and it can be either pleasant or unpleasant.

To test the aroma of an actual content, temporarily fill the lungs with air and, standing gently downward from the fumes, gently billow the odors toward the nasal passages with the hand.

Thus, the given statement is true.

How would the inability to make saliva affect digestion?
irina [24]
I believe the inability to make saliva would affect digestion drastically. The first phase in the process of digestion comes with saliva - it breaks down some substances in your mouth, because it contains amylase which helps during this process. If it weren't for saliva, you probably wouldn't even be able to swallow food - and even if you did, it would be almost impossible to break it down in your body.

Temka [501]

There have be found some fossils of ancient remains over the years. What the fossils from Atapuerca revealed about the hominins living in Europe at this time is below:

  • The Skull is known to show Interbreeding that took place with neandertals and their relatively healthy population.

  • The Fragment shows that there was a possibility of cannibalism in that area.

It shows that possible cannibalism took place as there were Cutmarks on various hominin bones found at Atapuerca mirror.

The relatively healthy population was found out through the study of the dentition of the Atapuerca hominins by anthropologists. It gave them a view into their diet and overall health.

The interbreeding with the Neandertals was shown through the Nuclear DNA that was gotten from bones and teeth of bones found at Sima de los Huesos

Alex73 [517]

The scenario will be Son: 25% colorblind daughter: 25% colorblind son: 25% of carrier daughters with normal vision: 25% normal son

<h3>What is color blindness?</h3>

The condition is frequently inherited. Certain eye diseases and medications are also possible causes. Men are more affected than women.

Color blindness is characterized by the inability to distinguish between red and green shades.

A colorblind man's genotype is XcY, and a heterozygous carrier female's genotype is XcX. A cross between XcY and XcX would result in progeny with the following ratio=

Son: 25% colorblind daughter: 25% colorblind son: 25% of carrier daughters with normal vision: 25% normal son.

Thus, the couple is likely to have a son who is half normal and half affected. Similarly, the couple is likely to have 50% normal daughters and 50% colorblind daughters.
