Explanation:

The sun heats the earth through radiation. Since there is no medium (like the gas in our atmosphere) in space, radiation is the primary way that heat travels in space. When the heat reaches the earth it warms the molecules of the atmosphere, and they warm other molecules and so on.

A piece of foam with an open cell structure is introduced into the wound and a wound drain is placed with lateral perforations on top. The entire area is covered with a transparent adhesive membrane, which is firmly fixed to healthy skin around the wound margin. When the exposed end of the drain tube is connected to a vacuum source, fluid is withdrawn from the wound through the foam into a reservoir for later disposal.It is necessary to cover the wound bed with a soft polyvinyl alcohol foam sponge, a non-stick oil-emulsion dressing (for exame, Johnson and Johnson), a contact layer (such as Mepitel), a thin layer of amorphous hydrogel (can be Intrasite Gel), or a calcium alginate (such as Sorbsan) before application of the gray sponge. Avoid the use of Vaseline, which is too oily and can alter the adhesion of the VAC cloth.

Answer:

Hailey, a local registered dietitian, frequently joins Aaron during his cooking classes at the local community hospital. Hailey often points out the common food sources of soluble fiber during Aaron's one hour cooking class. When working with patients and their families in their hospital rooms, she often explains to how common foods containing soluble fiber can play a major role in reducing the risk of having another heart attack. For this evening's cooking class, Hailey set up a display of five common items on a table and asked for a volunteer to select the ones which provide soluble fiber. During the cooking class, Jeff offered to try his hand at choosing the items which provide soluble fiber. Jeff should select all of the following items except:

canola oil

Explanation:

Canola oil contains fatty acid rather than fiber which Jeff is looking for among the food staples presented to him

What is the muscular system, what organs are involved, how does it work?

kifflom [539]

The muscular system is responsible for the movement of the human body. Attached to the bones of the skeletal system are about 700 named muscles that make up roughly half of a person’s body weight. Each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves. Muscle tissue is also found inside of the heart, digestive organs, and blood vessels. In these organs, muscles serve to move substances throughout the body.<span> </span>
