Explanation:

Nucleus                                                               Cytoplasm

Contains the genetic material (DNA)          Contains a thick gel-like substance

The most obvious structure in the cell       Contains all organelles      

Contains directions for cell regulation        Mostly water

The nucleus is a large and obvious organelle in the cell and it provides instructions for the regulation of the cell's activities and it contains the genetic material (DNA). All organelles are embedded in the cytoplasm which is made up of mostly water.

... termed "hypotonic," meaning less solids (or more diluted) than inside the cell. For fluid movement in/out of cells, water will diffuse (via osmosis) from the hypotonic solution to the hypertonic one, assuming a permeable barrier (i.e. cell membrane) allows it. With this case, water will flow into the cell from outside.

Describe the general types of diagnostic tests used to diagnose patients infected with HIV.
GenaCL600 [577]

AIDS

This disease leads to death by weakening the immune system of the human body.  Common symptoms are related to the nervous system like dementia, anxiety, depression and insomnia.

TESTS

The tests for AIDS are discussed below.

The most common test for any disease is the blood test.  

When human body is infected with the virus, the body produces anti-bodies to combat this infection. The blood test is positive if these anti-bodies are present in the blood sample of the infection person. However, it takes time for these anti-bodies to appear in the blood stream, hence, blood test should be done at regular intervals.

The tests specifically developed for AIDS are as follow.

ELISA or Enzyme-linked immunosorbent assay

If this test is positive, this is followed by a Western Blot test. The blot test is done in order to confirm the disease.

As said before, anti bodies take time to develop. If the test is done during this phase, it will be negative despite of the presence of virus in the blood stream.

HOME

Only one home test is approved. This is called Home Access Express Test. The kit of this home test is available at pharmacies.

SALIVA

The saliva from the patient’s cheek is obtained on a cotton pad. This pad is put in a vial which is then sent to the lab for testing.  If the result is positive, blood test is done to confirm the disease.

VIRAL LOAD

As the name suggests, this test measures the quantity of virus present in the blood. This test is done to either test the presence of HIV or to track the progress of the treatment of HIV.

WESTERN BLOT

This test is done when the result of ELSA test is positive. This test confirms the disease.

All the above test if turn out negative and the patient still doesn’t recovers, this testing should be done periodically until the disease is confirmed.

Glucose moves from the plasma into a skeletal muscle cell, where it is used for energy. Through which fluid compartment does glu
Tanzania [10]

Answer:

(B) Interstitial fluid

Explanation:

The interstitial fluid and blood plasma together make the extracellular fluid. The extracellular fluids are present outside the cells. The extracellular fluid that is present in the narrow spaces between cells of tissues is known as interstitial fluid. When a substance moves from blood plasma into the cells of a tissue, it crosses the interstitial fluid present between its cells. Therefore, when a skeletal muscle cell picks glucose molecules from blood plasma, it moves from plasma to the interstitial fluid to enter the cell.
