Assume that you are looking at cell cultures from the lining of the stomach, the wall of the heart, and a leg muscle, but the slides are not labeled. How can you identify each cell structure?

Answers

Answer 1

Answer:

It is possible to identify the cells of the stomach wall because of their elongated and rectangular shape. It is possible to identify the cells of the heart wall because of their branched and striated fibers. It is possible to identify leg muscle cells through the long, cylindrical fibers with many nuclei.

How to proceed when there are many cell cultures, without identification?

First, each cell culture should be observed under the microscope.
Next, the shape and cellular arrangement of the different cells should be observed.
Next, the intercellular structures should be observed.
Finally, specialists, books, and any material that helps with identification should be consulted.

To identify the cells it is also possible to perform staining tests. These tests require prior knowledge about dyes and how each one works, so they can be tricky for inexperienced people.

At the lungs.?A. both oxygen and carbon dioxide diffuse from the alveoli into the blood.
B. both oxygen and carbon dioxide diffuse from the blood into the alveoli.
C. oxygen diffuses into the blood and carbon dioxide diffuses into the alveoli.
D. carbon dioxide diffuses into the blood and oxygen diffuses into the alveoli.

Answers

At the lungs, oxygen diffuses into the blood and carbon dioxide diffuses into the alveoli.

• At the time of exchange of gases, oxygen moves from the lungs to the bloodstream.

• At similar time, carbon dioxide passes into the lungs from the blood.

• This takes place in the lungs between the network of tiny blood vessels known as capillaries and the alveoli.

• The molecules of the oxygen gas combines with the red blood cells that mediates back to the heart.

• The diffusion of carbon dioxide takes place out of the bloodstream, via the capillaries, and into the alveoli from where it is exhaled out.

• At the same time, oxygen combines simultaneously with hemoglobin and is carried back to the tissues.

Thus, the correct answer is option C.

Answer:

Explanation:

It can not be A. because if both oxygen and carbon dioxide diffused from the alveoli into the blood there would be too little oxygen and too much carbon dioxide.

If both oxygen and carbon dioxide diffused into the alveoli like in B. then that is even worse than the first one because that would leave our blood without oxygen that our body needs for functioning.

And D. can't be true because we don't run on CO2 but on O2 and getting rid of O2 for CO2 would kill us.

Imagine that you have been asked to give a short talk on the functioning of the auditory cortex. Make sure NOT to tell your audience that

Answers

The question is incomplete as it lacks the group of choices required to answer this. However, the complete group of choices is as follows:

a. the auditory cortex is located in the two temporal lobes.

b. the auditory cortex in each hemisphere receives information from both ears.

c. the auditory cortex of the left hemisphere receives information only from the right ear.

d. different areas of the auditory cortex are involved in language comprehension and production of language.

Answer:

The correct option is - C. the auditory cortex of the left hemisphere receives information only from the right ear.

Explanation:

In humans and many other vertebrates, the temporal lobe has a part that analyzes or processes auditory information known as the auditory cortex. It is an essential part of the auditory system that plays higher functions in hearing and processing it as switching languages.

The given options are correct so there would be no reason not to tell this to your audience, except option C which is incorrect, speaker should tell the audience that the auditory cortex in each hemisphere gets the auditory information from both ears.
