An MRI, or magnetic resonance imaging, uses a powerful magnet to pass radio waves through the body. Protons in the body react to the energy and create highly detailed pictures of the body's structures, including soft tissues, nerves and blood vessels. Unlike X-rays and CT scans, MRIs don't use any radiation.

Answer:

lymphocytes

Explanation:

Lymphocyte is a type of cell that is part of the body's immediate defense, acting against cancer cells and viral infections. Also, these cells are very important in wound healing. Slower healing of an injury is best explained by temporarily reduced lymphocyte production.

The concentration of these cells in the blood depends on the individual's physical condition: in cases of immunodeficiency, the concentration is low (lymphopenia); when there are infections or rejection of transplants, it increases (lymphocytosis). Lymphocyte count is a widely used test for monitoring diseases and infections such as those caused by HIV.

mote1985 [20]

Answer:

TRUE

Explanation:

Alzheimer's is a progressive degenerative disease that causes cognitive and memory impairment, as well as a variety of neuropsychiatric symptoms and behavioral changes that worsen over time. The causes of alzheimer's are still unknown, but researchers believe that for most people, Alzheimer's disease is caused by a combination of genetic, lifestyle and environmental factors that affect the brain over time.

Thus, there is a linear relationship between age and onset of alzheimer's, the older a person, the greater the chance of the disease to manifest. Usually the disease comes after age 75. The case of Sally's mother, who was diagnosed at a very young age at 50, gives evidence that her illness is manifested by genetic factors.

Which suffixes require the combining form of root words to be used? Check all that apply. -pexy -iatrist -ectasis -tocia -centes

uranmaximum [27]

The correct answers are: -pexy, -tocia, and -centesis. These are the suffixes that require the combining form of root words to be used. The combining forms are created with the combination of the word root and a vowel. Even though there are some exceptions, <u>the combining vowel is used if the suffix begins with a consonant</u>. If the suffix begins with a vowel (a-e-i-o-u), the combining vowel is not used. For instance, the suffix <em>-centesis</em> (puncture and aspiration of) requires a combining vowel to be used as in “paracentesis”: The doctor performed a paracentesis to remove fluid from the patient’s abdomen.
