Design your own scenario related to Bacteria or Viruses. Identify the independent and dependent variables.

Biology

Answer:

An experiment where an antibiotic is tested against bacteria. The antibiotic can vary in its concentration for example, different amounts are applied to a sample of bacteria to see if it is affected by the action of the antibiotic and if so, in what concentration. So, the independent variable is the concentration of antibiotic while the dependent variable is the survival (or not) of the bacteria.

Explanation:

An independent variable is a variable that represents a quantity that the scientist modifies in an experiment. A dependent variable represents a quantity whose value depends on how the independent variable is modified. This is the variable being studied and measured.

So, an example of this applied to bacteria or viruses could be:

<u>An experiment where an antibiotic is tested against bacteria</u>. The antibiotic can vary in its concentration, different amounts are applied to a sample of bacteria to see if it is affected by the action of the antibiotic and if so, in what concentration. So, the independent variable is the concentration of antibiotic while the dependent variable is the survival (or not) of the bacteria.

To complete the experiment, an antibiotic whose effect is already known can be used as a positive control. That is, it is already known to kill the bacteria. And as a negative control you can simply use water, which has no effect and is known not to kill the bacteria. In this way, we validate the results and make sure that there is not something else that is affecting the bacteria and that only the antibiotic being studied has an influence.

What dietary education should the nurse provide to a client diagnosed with a hiatal hernia?
soldier1979 [14.2K]
A hiatal hernia makes it easier for stomach acids to rise to the esophagus, usually called heartburn.
To reduce this symptom It's important a diet that consists of less: citrus, spicy, fried, fatty foods, coffee, tea, chocolate, carbonated drinks, dairy products and tomato (because it's also acidic). Some examples of appropriate foods are: apples, bananas, grains, soy milk, water, carrots, potatoes, peas, a low fat yogurt/cheese, (anything with low fat is ideal), etc.

The plasma cells of the immune system are responsible for secreting protein antibodies into the bloodstream. Within the plasma c
Butoxors [25]

Answer:

Ribosomes, endoplasmic reticulum, Golgi apparatus, vesicles.

Explanation:

The endomembrane system in eukaryotes has divided the cell organelles into the structural and functional unit. This system plays an important role in the protein processing, its sorting and transport of protein.

The protein is prepared from the plasma cells. The antibodies is made on the ribosomes by the translation process. From the ribosomes, it will move to the endoplasmic reticulum for the glycosylation and protein folding. Then it moves to the golgi for the further protein packaging and processing. With the help of the vesicles it moves to its destination part in the cell.

Thus, the correct answer is option (d).

Why are viruses considered nonliving but bacteria are considered living? Give to reasons.
Andreyy89
Viruses aren't made up of living cells, like plants and animals are, they either consist of DNA or RNA surrounded by coating of protein. Versus also like the properties of living things. They have no energy, they do not produce waste, and they do not respond to stimuli. they do not reproduce independently but must rely on invading living cells and feeding off a them.

Therefore, there are many reasons my viruses are considered non living but the biggest reason is because they cannot survive on their on and have to feed and get their nutrients off of living things

And bacteria is considered living because it can do all these things that viruses cannot do.
