natta225 [31]

According to the research, the correct option is control. Experiments are carried out to test a hypothesis by changing one variable at a time and including an unchanged variable termed a <u>control</u>.

<h3>What are Experiments?</h3>

It is the process by which one or more variables are intentionally manipulated by carrying out actions aimed at discovering or verifying certain phenomena.

In this sense, its basis is in the manipulation of the variables that are considered relevant, the control of strange variables and the randomization of the rest.

Therefore, we can conclude that according to the research, the correct option is control. Experiments are carried out to test a hypothesis by changing one variable at a time and including an unchanged variable termed a <u>control</u>.

How should food workers protect food from pathogens?
Sonja [21]

Between usage with various meals, food service personnel should clean and sterilize surfaces, tools, and utensils, especially after handling raw meat. Foods that are ready to consume should be kept in the refrigerator's highest shelves. This will prevent the juice from raw foods from dripping down and contaminating the prepared food.

<h3>How may pathogens be kept out of food?</h3>
  • Wash hands and other surfaces often.
  • Before and after handling food, going to the bathroom, changing diapers, or touching pets, wash your hands with soap and hot water.
  • To clean up spills or kitchen surfaces, use paper towels or clean cloths along with hot, soapy water.
<h3>How do food workers guard against viruses on their hands contaminating food?</h3>

The gloves that food workers wear could be infected with harmful infections if they don't properly put them on or don't wash their hands before putting them on. Every time an employee dons a fresh set of gloves, they must wash their hands first.

<h3>How can employees prevent food from becoming contaminated after it has been cooked?</h3>

To make sure food is safe to eat, use a food thermometer, keep food hot after cooking (140°F), and microwave food thoroughly (165°F). Refrigerate right away because if perishable goods aren't chilled, bacteria that cause disease can grow in them in just two hours.

how could measure whether or not the chemical reaction that breaks down hydrogen peroxide is occurring
d1i1m1o1n [39]

Answer:

You could check the pH!

Explanation:

This is an idea, when you break down H2O2 (Hydrogen peroxide) you will be left with H2O (Water) and O2 (Oxygen gas). H2O2 theoretically would have a lower pH than water. Water has an average pH of around 7 while H2O2 will have a pH of about 4.5.

So theoretically to figure out if hydrogen peroxide is being broken down you can test for the pH. This is a very simply process, you just stick a little peice of litmus paper into the solution and immediatly it will change color to tell you the pH.
