Explanation:

Stimulus in biology can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.

In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ. Therefore, the senses are necessary for behavior because stimuli must be sensed in order to respond.

Stimulus control can be defined as a phenomenon that arises when a living organism responds or behaves in the presence of a stimulus and in another way in the absence of a stimulus.

For example, opening the door of a microwave oven as soon as its timer beeps.

Example II; When your body touches a hot object, you quickly move away and feel some pain subsequently.

You are going to write a personal reflection on the topic of bullying. Even though this topic may make you feel uncomfortable because it will require you to admit to your own poor choices, it is always great to be reflective of our actions.
In this personal reflection, you are to write about a time when you were unkind to someone else. You will identify the things that you did or said and then write about why you chose those actions at the time.
Then, you are to write about how your actions or words may have made the other person feel. Finally, at the end of the reflection, you are to write out a better plan of action for how you could have handled a similar situation in the future.

Answers

Answer:

I think I have made some poor choices but I would never call my choices as "bullying" another. I personally have been bullied before in elementary school when I first moved to the United States from Korea without knowing any English or anything whatsoever when I was 6 years old? It was pretty rough. I made some hard choices in being unkind to another out of selfishness sometimes, because it was something I wanted and worked hard for that another was going to get if I didn't speak up for myself and make a couple poor decisions instead. I cannot say that any of my actions stand out. I really can't think of anything. But I will say that I have made some poor choices and to solve that in the future, I should think more of how my actions would benefit me but how it would ALSO benefit the other person too.

Answer:According to the Centers for Disease Control and Prevention, approximately 48 million Americans get sick, 128,000 are hospitalized and 3,000 die each year from food poisoning.

Bacteria, viruses and parasites are the sources of many food poisoning cases, usually due to improper food handling. Some bacteria, in small amounts, are not harmful to most healthy adults because the human body is equipped to fight them off. The trouble begins when certain bacteria and other harmful pathogens multiply and spread, which can happen when food is mishandled. Foods that are contaminated may not look, taste or smell any different from foods that are safe to eat. Symptoms of food poisoning vary and develop as quickly as 30 minutes to as long as several days after eating food that's been infected.

As identified by the CDC, eight known pathogens (bacteria, viruses and parasites) account for the majority of foodborne illness, hospitalization and death in the United States.

Salmonella

Salmonella is the name of a group of bacteria that causes the infection salmonellosis. It is one of the most common bacterial causes of diarrhea and the most common cause of foodborne-related hospitalizations and deaths. Salmonella is more severe in pregnant women, older adults, younger children and those with a weakened immune system. Because Salmonella bacteria can live in the intestinal tract of humans and other animals, it can spread easily unless you use proper hygiene and appropriate cooking methods.

Sources: You can contract salmonellosis by consuming raw and undercooked eggs, undercooked poultry and meat, contaminated raw fruits and vegetables (such as sprouts and melons), as well as raw milk and other dairy products that are made with unpasteurized milk. It also can be transmitted through contact with infected animals or infected food handlers who have not washed their hands after using the bathroom.
