<span> Communicable diseases
are also known as infectious or contagious diseases. They may come from food,
water, animals, another person, or anything that comes from the environment. <span>Airborne
viruses, bacteria, blood, and bodily fluids can cause the spread of these
diseases. The most common communicable disease is the flu, which can easily
spread in an enclosed environment with a recycled circulating air (e.g.
air-conditioning). Infectious disease caused by blood contact like HIV/AIDs are
also dominant in society. </span></span>
After about 3-8 hours is starts to stiffen, and from approximately 8-36 hours it will be stiff and cold. The body becomes stiff because of a range of chemical changes in the muscle fibres after death.

Answer: Alcohol reduces the amount of oxygen that enters your bloodstream by<em>B; slowing down your respirations. </em>
Explanation:
When a person consumes alcohol this affects the pulmonary system in the body. This is the system the body uses to get oxygen to the blood. This also takes the carbon dioxide out of the blood. When alcohol is consumed all of the parts of the system is affected including the lungs. Since alcohol reduces the respirations of person drinking this will cause the oxygen in your blood to be reduced.
Use a condom: A condom is the easiest and most effective way (after abstinence) to prevent against a sexually transmitted disease. Made of latex for men and polyurethane for women, condoms prevent the passage of disease-causing organisms such as HIV and prevent unwanted pregnancies. It is estimated that the risk of disease transmission with condom use is only 5%.
Have few sexual partners: The large number of sexual partners can favor contamination by some sexually transmitted disease as it exposes individuals to a greater number of sexually active people. Therefore, one way to prevent disease is to have few sexual partners.
Do not use drugs: Drug use is largely responsible for the transmission of sexually transmitted diseases. This is because many people share syringes, needles and other objects that favor contamination. In addition to the risk of transmission due to the use of objects with biological material, drug use favors STD contamination because it can lead to risky behavior such as unprotected sex. Thus, STDs can be avoided by not using drugs and not sharing sharps.
