If i wanted to look at a onion cell what type of microscope would be best to use

1 answer:

7 0

It is best to use regular light microscopes to observe that.

For simple structures, onion cells doesn't require a very large magnification. Magnifications for such as 100X or 150X is already enough to determine the different structures of onion cells such as cell walls or cytoplasm.

It is not very suitable to use a electron microscope especially as high school or college students, as electronic microscopes can be really expensive, usually only top universities have them. Also, it is quite complicated to control the microscope comparing to the common light microscope that we can easily find in many school laboratories. They're easy to function and they're a lot cheaper.

So, it's best advised to use a light microscope, unless if you're really into studying very detailed structures and you're experienced in doing these sorts of things, then you should use a electron microscope.

To test the quality of water sources in her area, Shameka collects five samples from each water source and tests the quality of

Neporo4naja [7]

Of the steps included in the scientific method, Shameka is performing step five, which is to test your hypothesis by performing an experiment.

The scientific method is the globally accepted process by which to make scientific claims. This method includes seven steps which are:

Ask a question
Do research
Create a hypothesis
Design an experiment to test the hypothesis
Perform the experiment
Study the results and make a conclusion
Communicate the results to your peers.

The question states that Shameka is gathering samples from nearby water sources, therefore she is in the process of testing her hypothesis through experimentation, which corresponds to step 5 of the scientific design.

Becky is a 53-year-old woman living in Seattle, Washington, with her husband Tim and their dog Tipper. Even though they both hav

Alika [10]

Answer:

Becky’s doctor provided only supportive care because the toxin that poisoned her, the demoic acid, has no known antidotes; which happen to be the only cure for toxins.

Antimicrobial were not part of Becky's treatment because Becky was infected by a toxin and not a microbial infection.

Diatoms are not different from eukaryotic cells or eukaryotes. they are Eukaryotes, which are different from prokaryotes. However both the eukaryotes (diatoms) and the prokaryotes possess cytoplasm, plasma membrane and ribosomes.

Explanation:

Demoic acid is a marine bio-toxin that results in Amnesic Shellfish poisoning (ASP). This biotoxin is produced by diatoms of the species Nitzschia navis-varingica of the genus Pseudo-Nitzschia. This intoxication can result in symptoms ranging from gastrointestinal upset (vomiting, nausea, diarrhea, abdominal cramps, hemorrhagic gastritis) to neurological disturbances (including headaches, diziness, disorientation, vision disturbances, loss of short term memory, motor weakness, abnormal heart rhythm, unstable blood pressure, etc.). In more severe cases, it could lead to permanent short term memory loss, brain damage, coma, and death. Due to the lack of antidotes for this toxin, it is advised that medical attention be sought as soon as possible, where the patient can be closely monitored and cared for.

There's a difference between toxins and microbial infections. while Microbial infections are caused by harmful microorganisms infecting the body tissue and cells, toxins are harmful substances produced by microorganisms. Hence, the approach for treatment for both cases are different.

Diatoms are eukaryotic cells or eukaryotes, which are organisms that have a membrane enclosing in their nucleus, hence they have a true nucleus and organelles bound by a membrane, supporting functions in compartments. Prokayotic cells or prokayotes, on the other hand, which are typically smaller, do not possess a protective membrane around their nucleus or any organelles enclosed by the membrane. Regardless of their differences, they still both share similarities. After all, they both are cells. So they have the basic features of cells. These similarities include the possession of a cytoplasm, ribosomes, plasma membrane.
