Cross-connections, which are physical links between clean and potential sources of contamination, present several risks primarily concerning health and safety. These risks include the transmission of diseases through contaminated water or medical equipment and electrical hazards in case of improper wirings.
A cross-connection exists when there is a physical link between a clean water source and a potential source of contamination. The risks associated with cross-connections primarily relate to the health hazards of consuming contaminated water, such as disease transmission, and possibly, complications ranging from gastrointestinal issues to fatal illnesses.
For example, in health care settings, a cross-connection might involve pathogens potentially introduced into the bloodstream via contaminated catheters, dental procedures, or wounds. This connection could lead to increased risk of diseases like Hepatitis B. In more severe scenarios, cross-contamination could lead to outbreaks like the one seen in the Flint, Michigan, water crisis, where pollution in the city's water system led to widespread health issues.
Moreover, cross-connections in electrical systems also present risks, like thermal hazards where excessive electric current causes undesired heating effects or shock hazards, potentially lethal electric currents passing through a person.

B). High Cost
C). Radiation Exposure
D). Health Risk
Answer Is : High Cost
yes, the answer is b) high cost
Answer:true
Explanation:
this is true because tightness makes blood pressure underestimate
B)sleep habits
C) climate
D)poverty
Sleep habits is a controllable risk factors for disease. Taking less sleep than normal can lead to disease. Thus, the correct option is B.
Factors which could lead to disease are of two main types which are controllable and uncontrollable. A controllable factor for disease riskcan alter or influence if a person wish to do so or can control a disease set by changing these factors.
An uncontrollable factor is the one which a person cannot easily alter by choice. If a person depend on the teacher for success or if a person compete with their peers for the few available high grades, he explain his situation by pointing to the uncontrollable factors.
Some examples of controllable risk factors for disease are sleeping habits, poor diet, and nutrition, physical inactivity, spending too much time in the sun or in front of the screen, and not having certain vaccinations.
Therefore, the correct option is B.

Answer:
pneumcyistis carinii and Kaposi's sarcoma
Explanation:
A weak immune system leaves the body defenseless and an immunodeficiency can develop. In contact with a certain antigen, the immunodepressed person is unable to create antibodies since his cells are no longer functioning. A simple flu can end up developing into pneumonia and also lead to death. It is the case with HIV patients, that the virus destroys their immune system making them susceptible to these microorganisms. In this scenario, people with HIV are very susceptible to opportunistic diseases that take advantage of the individual's debilitating state to manifest themselves.
Two examples of opportunistic diseases that can harm a person with HIV are: pneumcyistis carinii and Kaposi's sarcoma.
Answer:
Underground!
Explanation:
In a car: A car is not a safe place to be during a tornado. Tornadoes can easily lift and toss vehicles, making this a very dangerous choice.
Lying on the ground: This is also not a safe option because flying objects around you could bump towards you and get hurt or worse.
Underground similar to basement: This is the safest option. Tornado shelters or basements provide the most protection from the tornado's destructive forces.
In a bathroom: If you don't have an underground, go into a bathroom. It's much safer than the other two questions.
