A client performs two repetitions of a bench press exercise with 130 lb and gradually decreases the resistance with each set unt
blagie [28]

Answer:

The correct answer is c. The client is using a Pyramid system.

Explanation:

The pyramidal method owes its name due to its structure: it is based on the gradual increase and decrease of the weight that we must ballast (if we require it in an exercise with ballast) or if we prefer it without additional weight, a gradual increase or decrease of the repetitions . All this increase and decrease in repetitions and / or weight, occurs in a staggered manner between each series for a single exercise, with the aim of being able to recruit a very high number of muscle fibers. It is usually done ascending or descending.

The descending pyramidal method consists of lowering the load, but increasing the repetitions, that is, it begins by applying large loads from the beginning and few repetitions, until ascending in the pyramid and completing the exercise having increased the repetitions and reducing the weight used. With this type, what we achieve is called the strength-resistance of the muscles.

Match the staining techniques with their purpose.
Dennis_Churaev [7]

A Negative stain such as India ink or Congo red-Look for the presence of a capsule.

This stain method is usually used to stain the area around the microorganism.

B The Gram stain-Divide bacteria into two groups based on cell wall structure (thick vs. thin).  

This is type of differential staining used to distinguish organisms based on their staining properties. Gram + and Gram- bacteria stain different because of different cell wall structure.

C The Ziehl-Neelsen Acid-fast stain- Identify bacteria with waxy cell walls such as: Mycobacterium tuberculosis (the cause of TB).  

This is also differential staining method which uses heat and phenol to derive dye into the cells with lipid-rich walls.

D Simple stain with a basic dye-Stain microbes a bright color to make it easier to see them in bright field microscopy.

One dye is used in simple staining in order to determinate the size, shape and arrangement of the cells.

E The Schaeffer-Fulton Endospore stain-Identify Bacillus or Clostridium species, such as the causative agents of anthrax, botulism, tetanus and gangrene.  

This is a special type of staining only used for the bacteria that can form endospores. Bacteria are first treated with heat and then with malachite green, which is very strong stain that can penetrate endospores.

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.
