Describe how one of the occupations that you studied would use descriptive statistics when performing their job

riadik2000 [5.3K]

Answer:

Given the nature of descriptive statistics, psychologists will use descriptive statistics to assemble data about their clients through their observations of clients' behavioral patterns. Then a sample of the data will be taken. The sample is summarized statistically, interpreted, and recorded. Psychological reports can be issued based on the observed statistical results.

Explanation:

Psychologists and other occupations use descriptive statistics to describe the basic features of the data in their studies or experiments. Descriptive statistics provide simple generalizable summaries about the observed sample and the calculated measures. Using simple graphics, they form the basis of quantitative data analysis.

Describe all muscle tissues, including cell shape, layers, intercellular connections,

zmey [24]

<h2>Description of muscle tissues. </h2>

Explanation:

There are three types of muscle tissue are cardiac, smooth, and skeletal.

1. Cardiac muscle tissue: It is located in the walls of the heart.

They appear striated.

Control is involuntary.

Function: To pump blood through the blood vessels in your body.

2. Smooth muscle tissue: It is located in walls of hollow visceral organs, except the heart.

They appear spindle-shaped.

Control is involuntary.

Function: To move food through the digestive tract.

To regulates air flow in lungs.

3. Skeletal muscle tissue: It occur in muscles which are attached to the skeleton.

They appear striated.

Control is voluntary.

Function: To support the body.

It makes bones and other body parts move.

Cell shape : There are different shapes of cells which are as follows:

1. Squamous 2.Cuboidal 3. Columnar 4. Polygonal 5. Stellate

6. Spheroid 7. Discoid 8. Fusiform 9. Fibrous.

Muscular layer: The muscular layer is present in many organs in the vertebrate body.

It is responsible for peristaltic movement in body.

There are two layers of muscle.

1. Inner 2. Outer layer.

Inner layer: The muscle of the inner layer is arranged in circular rings around the tract.

Outer layer: the muscle of the outer layer is arranged longitudinally.

Intercellular connections or junctions: These are the structures which provide adhesion and communication between cells.

There are mainly three types of junctions:

1. Tight junctions: It help to stop substances from leaking across a tissue.

2. Adhering junctions: It perform the function of cementing so as to keep neighbouring cells together.

3. Gap junctions: It facilitate the cells to communicate with each other by connecting the cytoplasm of adjoining cells, for rapid transfer of ions, small molecules and sometimes big molecules.
