1. No conversions. The greatest advantage of SI is that it has only one<span> unit for each quantity ( a type of measurement). This means that it is never necessary to convert from one unit to another (within the system) and there are no conversion factors for students to memorize.

2. </span><span>No fractions. SI uses decimals exclusively, eliminating clumsy fractions and mixed numbers.</span>

How is HIV contracted, and what are the treatment options?

Katena32 [7]

I believe the correct answer is: HIV is spread during unprotected sex or through contact with infected blood; it cannot be cured, but early treatment can minimize the long-term consequences.

<h2>Explanation:</h2>

Human Immunodeficiency Virus is a type of virus which causes an impairment of the immune system of the person making them susceptible to diseases such as tuberculosis, influenza and any other disease that can exploit this opportunity. It is spread by a person coming into direct contact with infected bodily fluids such as saliva during deep kissing, semen during intercourse, blood after an accident or even fluids when sharing needles and syringes for drug addicts. There is no cure but the current form of treatment slows down the virus to prevent some consequences.

<h2>Further Explanation:</h2>

The virus is enters the body through open wounds or surfaces such as the vagina or mouth where the skin is very thin and can tear. After penetrating the skin, it attaches to specific immune cells called CD8+ T-cells on points called receptors. It then enters the cell and replicates itself in the nucleus of the cell and as it goes out, it kills these immune cells making the person to have a weak immune system. The current drugs used called AntiRetroVirals (ARVs) such as the drug Zidovudin stops the virus from replicating thus reducing the total amount of virus in the body called the Viral Load. Some drugs target enzymes called proteases and reverse transcriptase that help the virus to replicate. This viral load is what is counted to estimate the total volume of HIV someone has in their body. Infected persons should use protection while having sex and also avoid sharing sharp objects to prevent transmission. They also need to take their medication to make them much more healthier in addition to taking proper balanced diets.

A client has undergone a left hemicolectomy for bowel cancer. Which activities prevent the occurrence of postoperative pneumonia

Hunter-Best [27]

The measurable activities like Coughing, breathing deeply, frequent repositioning, and using an incentive spirometer are for preventing postoperative pneumonia. Hence, Option C is correct.

<h3></h3><h3>What is postoperative pneumonia?</h3>

Pneumonia is caused by Streptococcus pneumoniae and Haemophilus influenzae leads to infection of the alveoli of lungs.

This type of pneumonia is a rare medical condition happens after local anesthesia has been given to a patient.

The primary causes are the amount of anesthesia given, poor handling of chemicals, the type of anesthesia given to the patient.

To prevent the occurrence of postoperative pneumonia are medicating the patient and use of incentive spirometer. Hence, Option C is correct.

Water makes up approximately 60% of the human body and plays a vital role in regulating body temperature. Which property of wate

jeka57 [31]

Water has a high heat capacity, or the ability to "hold on to" heat well; this property aids in the regulation of body temperature in both organisms and cells. Sweating is another way that water can be used to cool down an overheated organism.

Warm-blooded animals employ water's high heat capacity to more efficiently distribute heat throughout their bodies.
Water works like a car's cooling system, moving heat from warm to cold areas and allowing the body to maintain a more constant temperature.
The body requires water to maintain temperature because it is a good heat conductor and absorber.
Water can absorb a lot of heat before its temperature increases because of its large heat capacity.
This characteristic enables the water to function as a buffer against abrupt temperature changes in every cell of the human body.
