Why is it necessary to model the concept above?

Biology

Answer:

You did not write the concept, so i will try to answer in a general way.

Why sometimes we really need to model concepts?

Well, sometimes the things are really complicated, or we just do not have the knowledge or tools to fully understand them.

Here is where the models came to be handy, we can somewhat "simplify" the things, and explain them with models.

For example, the movement of a particle as the wind pushes it can be really complex, so this can only be explained with a model.

Now, once we have a model (supported by theory and experiments) we can start to investigating furthermore in the given subject.

So for example, we could model how a given therapy acts on a given disease, and with that model, we could extrapolate the effects of the therapy in a similar disease (for example, testing how radiotherapy acts on a given tumor in some organ, can give information on how the same therapy can act on other types of tumors)

Concluding, models simplify some concepts, which allow us to understand them and work better with them

During an experiment, readings for blood pressure in a person’s body were found to be constant. However, when measured by a diff
DENIUS [597]

Answer:

This difference indicates that the results are precise but not accurate .

Explanation:

Precise results are those that are very close to the actual result, but do not achieve exactly the same result. In addition, this difference between the precise results is exactly the same. We have an example of this in the case shown in the figure above, where the blood pressure readings measured by the cuff differ by 15 points for each reading. This case also shows us that the results are not accurate, because this type of result is one that shows a result exactly the same as the real one.

Sara and Juan conducted an experiment to test which soil would be BEST for growing plants.
pantera1 [17]

Answer:

A. Type of soil

Explanation:

A control experiment is the one that is used to checkmate the real experiment.

In this case, the fourth jar that contains the mixture of all the types of the soil is considered as the control experiment.

In a nutshell, it should be generally understood here that the type of soil serves as the control for the experiment.

What are the keys to a strong lab procedure?​
Natali5045456 [20]

Answer:

Purpose: A brief description of why the experiment is being performed. Include details about the experiment, such as the methods used, a specific chemical reaction(s), and/or anticipated product.

Hypothesis: Provide a statement or two about the anticipated outcome of the experiment.

Experimental Procedure: A step-by-step description of the experiment including the chemicals, equipment, and/or methods used. Complete sentences must be used for the description. DO NOT simply copy the procedure from a lab manual or a handout. Condense the given procedure into steps so that you can understand and follow them.

Laboratory Safety: Give a complete, descriptive listing of the safety precautions, hazards, or other safety procedures that are needed for this experiment.

Experimental Data: Record all data resulting from the experiment in your laboratory notebook. The experimental data should be recorded in tabular form. Do not record your experimental data in your laboratory manual.

Observations: This section is used to record any qualitative observations and notes on the changes to the experimental procedure. Sudden bursts of scientific insight or other information during the experiment that may aid in the interpretation of the data generated are to be entered in this section. No points will be awarded when the observations are recorded outside of the laboratory. It is also important that you record your unknown number in this section of your notebook.

Calculations: Present outcome/summary of data analysis using tables, Excel graphs, and/or figures. List separately all pertinent mathematical equations followed by a sample calculation for each. Use the recorded data from the experiment when performing the calculations.

Results/Discussion: Questions that should be addressed in this section may include: Did the experiment work, and if not, why not? Were the results obtained in the experiment those expected based on the laboratory procedure? If the experiment was to be repeated, what improvements would be made? What types of errors occurred and how could they be corrected? How did the observations play a role in the outcome of the experiment? When applicable, you should compare your experimental value(s) to that of a published, literature value(s), commenting on the accuracy of your technique.

Conclusion: Summarize the findings of the experiment, which must include the final results of the experiment, e.g., the percent yield of a reaction, the identity of an unknown, etc. Look back at the purpose and hypothesis of your experiment and assess whether or not you met your goal in performing the experiment.

References: Include all pertinent information such as, your laboratory manual, textbooks, web sites, and any other library resources used in the preparation of your laboratory report.

2. Ms. L's respiratory function was evaluated by quantifying different lung volumes and capaci-
Sphinxa [80]

Based on respiratory function tests, the correct options are:

  • spirometer.
  • vital capacity
  • residual volume.

<h3>What is a respiratory function tests?</h3>

A respiratory function test is a test done to evaluate the ability of the lungs to take in air and remove carbon dioxide

The machine used for this test is called a spirometer.

Therefore;

  • Ms. L's respiratory function was evaluate using a machine called a spirometer.
  • The amount of air that can be expelled by maximum ex-halation after maximum inhalation is termed the vital capacity
  • An increase in the amount of air remaining in her lungs after a normal expiration is called the residual volume.
