Why does a hot air balloon rise?

1 answer:

5 0

Answer: Hot air is less dense than cool air; the heated air causes the balloon to rise simply because it is lighter than an equal volume of cold air. Buoyancy is an upward force that the air exerts, and it helps hot-air balloons and blimps stay in the air. A hot air balloon uses a burner to heat up the air inside the balloon.

Hope this helps!!! Good luck!!! ;)

A jar contains 26 fluid ouncesbof spaghetti sauce. How many cups of spaghetti sauce do 4 jars contain

JulijaS [17]

____________________________________________________

Answer:

Your answer would be 13 cups of spaghetti sauce.

____________________________________________________

Explanation:

Lets break down this question to make the answer easier:

8 ounces = 1 cup

We are going to use the above to help us solve this question.

In your question, you have 26 ounces, and you would have four cups. You would need to calculate how many ounces are in the 4 cups

To do this, you would multiply 26 by 4:

26 × 4 = 104

The four cups have a total of 104 for ounces. But, you are not done solving yet. You need to found how many cups there are. We would be going to use the 8 ounces, since we know that is the amount of one cup, and use that to divide 104, since we need to distribute the amount of ounces to the cups.

You would divide 104 by 8

104 ÷ 8 = 13

There would be 13 cups of spaghetti sauce in 4 jars of spaghetti sauce that has 26 ounches in it.

Your FINAL answer would be 13.

What is clear here is that sedation was provided by a physician or other qualified health care professional. Read at the CPT Coding Changes For Moderate Sedation in 2017. It states there will be several codes for moderate sedation. Your statement of the case is not complete, as age is important. The codes for moderate sedation is 99151 to 99157.

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.
