Infection occurs when: 1. A person inhales microbes in the air. 2. Contaminants are present on the skin. 3. A person swallows microbes in/on food. 4. Pathogens enter and multiply in body tissues. 5. All of the choices are correct.

4. Pathogens enter and multiply in body tissues.

Explanation:

When pathogen penetrates the host defenses, infection occurs in the host. Infection is a disease of the body that is caused by invasion and multiplication of pathogens (infectious biological agents that causes diseases or illnesses to the host) such as bacteria, viruses, parasites and so on normally not found with the body. They can easily spread from their point of origin if not contained due to the multiplicability of the pathogens causing it.

When pathogens enter and multiply in body tissues

Explanation:

Disease enter our body system, when several pathogens like viruses, bacteria, or other microbes enter our body system and start to produce or multiply. Bacteria sometimes, produce so rapidly or speedily on the host tissues and disrupt normal body function. Pathogens kills or destroy the cells and tissues when they enter the body system. Pathogens usually enter the human body system by two main types of routes: mucosal surfaces within the body which includes, the linings of the respiratory, digestive, reproductive, or urinary tracts and the epithelial surfaces on the outside of the body which includes, areas of skin that are either undamaged or compromised due to insect bites, cuts or scrapes.

minerals contribute to our overall health because they your body grow, develop, and stay healthy. our bodies use minerals to us function throughout the day.tromhey us build strong bones, so we can do more things in life. with certain minerals, they can you maintain a normal heartbeat!

though, as as minerals are for us, they can also be very dangerous if one were to consume too many. if you were to take too much minerals, or even vitamins, you could experience nausea and diarrhea. all trace minerals can be very toxxic at high levels of consumption. taking too much of some minerals will result in hair loss! but this goes with almost everything in life, taking too much of something that is good, will eventually be bad for you.

my intake in minerals was normal. there really is no need to improve, i am healthy, and i am experiencing no nausea or diarrhea. i am as healthy as a bee. ☺ (sorry that i cannot you with the mineral intake)

what i have learned so far is that taking too much something can be very bad for you. taking too many minerals or vitamins, or anything healthy in general, can result in nausea and diarrhea, as well as hair loss. it would be a good idea to track what you put into your body, good or bad.
