Answer: PALPATION.

Explanation: Palpation is one of the the ways of physically examining an individual,it involves using one's fingers to examine the organs of the body to note any abnormality.

This is achieved by touching and feeling the the body inorder to determine the location,size,consistency or firmness, shape, tenderness and the texture of a body organ or to get the location of pain.

Palpation is mainly employed in physical examination of the abdomen and it can serve as a diagnostic approach to ascertain the presence of a disease condition or injury.

Palpation can be deep palpation (4-5cm) to feel internal organs of the body and to note any mass or tumour or light palpation(1-2cm) to feel surface abnormalities.

Answer:

palpation

Explanation:

The correct answer would be palpation.

Palpation is a medical term that generally refers to the process of using fingers to diagnose diseases or identify body abnormalities.

By using the sense of touch, different characteristics of the body region are assessed and the information is collated and critically examined to arrive at a diagnosis.

Palpation can be conducted using the fingertips, the finger and the thumb, the back of the finger and the hands, the side of the hands, or the front of the fingers

A hemocytometer is a tool used in the laboratory for counting cells in suspension, it consists of a microscope slide that has a rectangular indentation that forms a chamber where the cells are stably maintained and counted.

The cerebrospinal fluid (CSF) is a liquid that is localized around the brain and spinal cord. Moreover, CSF analysis is a set of laboratory tests to measure the number of red and white blood cells.  

The CSF tests are useful to detect different health problems that affect the central nervous system including, among others, infections in the brain (encephalitis, meningitis), inflammations, tumors, multiple sclerosis, etc.

In a CSF test, the number of white blood cells should be very low, and relatively high concentrations of such cells may be indicative of multiple sclerosis, encephalitis, leukemia, hemorrhage and allergy.

Current procedural terminology are codes tag are formulated by America doctors for medical procures, evaluation, surgeries and billings. They serves as guide for treatment administration including surgery.

There are two types of CPT codes,

The CPT code is divided into 3 category based on the function.

We have codes used for medical procedures and the ones for medical billings.

The code is five digits and it can either be in numbers or alpha numeric.

For billing we have four digits and one alphabet F at the end of the 4 digit they help for further clarification. The four digit explain the treatment, evaluation ,drugs administered from where the billing comes from while the F is to identify the category of codes.

Answer:

The ecosystem comprises of the producers, consumers and decomposers. The basic interaction of the ecosystem include:

Predation, parasitism, competition and herbivory

Predation is the interaction which occurs between the predators and preys. They are consumers and the higher and stronger animals use and eat the lower animals as their source of food e.g a lion and zebra or toad and grasshoppers

Parasitism occurs when an organisms feed on the resources of a host which could be blood or nutrients without necessarily having to kill it.

Competition occurs across all the organisms in the ecosystem. There is always competition for light, space, water and food.

Herbivory is common with herbivores who feed on plants and are known as primary consumers as they obtain their energy straight from the chemicals source of plants.

The small molecules consisting of an amino group, a carboxyl group, and a side chain describes the structure of an amino acid.

Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although over 500 amino acids exist in nature, by far the most important are the alpha-amino acids, from which proteins are composed.

Amino acids function as the building blocks of proteins. Proteins catalyze the vast majority of chemical reactions that occur in the cell. They provide many of the structural elements of a cell, and they help to bind cells together into tissues.

Amino acids connect to form peptide bonds through a reaction between the amino group and the carboxyl group. The amino functional group is therefore critical to building all the proteins that makeup life on earth.

Distilled Water

1% Salt Solution

3% Salt Solution

5% Salt Solution

Place the “Distilled Water” cup on the balance and press the “TARE” button.

Add 3 pieces of potato to the “Distilled” cup

Record the MASS in grams (g) in the Distilled “Initial Mass” column of the data table.

Remove the cup from the balance.

Measure out 100 ml of Distilled Water and pour into the cup.

Cover the cup with foil and set aside.

TARE the balance again to ZERO the mass.

Repeat steps 2-8 with the 1%, 3% and 5% cup

Write a hypothesis in the labeled section of the Osmosis Lab Report Template Preview the documentprovided or as directed by the teacher.

Refer to the conclusion section. Draw illustrations of each cup and its contents. Details of the illustration will be added later.

Part 2: Obtaining Results

After approximately 24 hours, use tongs to remove the “Distilled” pieces of potato from the labeled beaker.

Pour out the liquid from the cup into the sink or other specified container.

Take a piece of paper towel and carefully dry the inside of the cup.

Gently blot/dry the potato piece with a paper towel to remove excess water. DO NOT PRESS the potatoes.

Document how the potatoes feel at this time.

Place the empty "Distilled" cup on the balance and TARE.

Quickly place the potatoes in the cup and find the mass.

Record the mass in the FINAL MASS (g) column of the data table.

Record, in the NOTES section of your notebook, all observations of the texture, color and flexibility of the potatoes.

Calculate the percent change in mass (see example below) and enter into the provided data table.

12. Graph your data.

PART 3: Illustrations and Conclusion

In the labeled spaces provided in the Osmosis Lab Report Template draw and label pictures to illustrate what happened during the experiment.

Use arrows to show the movement of water.

Use the following labels to indicate the state of the solution/liquid: hypertonic, hypotonic, and isotonic.

Write a conclusion which states whether your hypothesis was or was not supported in addition to citing data as support.

Answer:

A hypothesis is a tentative/ preliminary statement of the relationship between two or more variables. It is a specific, testable prediction about what you expect to happen in a study.

Explanation:

In science, the hypothesis is an idea or explanation that you then experience/test through study and experimentation. Outside science, theory or guess can also be called a hypothesis. The hypothesis is nothing more than an unbridled, wild guess but less than a well-established theory.

So, we can conclude that The hypothesis is a simple statement that defines what you think the outcome of your experiment will be.
