Which three food handlers cause cross-contamination of food?
- Jason pauses prepping vegetables for a soup and scratches his scalp and then resumes his
task.
- Kim preps raw salmon on a cutting board and then slices tomatoes on the same cutting board.
- Leandra preps hamburger
patties thawed overnight at room temperature.
- Immanuel mixes undercooked chicken with greens for a salad.
- Mina uses an unclean cloth to wipe a tray that will hold cookies.
Kim is cross-contaminating food by using the same cutting board for raw salmon and tomatoes. Leandra is cross-contaminating food by thawing hamburger patties overnight at room temperature. Mina is cross-contaminating food by using an unclean cloth to wipe a tray that will hold cookies. Hence Kim, Leandra, and Mina are contaminating the food.
Kim is using the same cutting board for raw salmon and tomatoes. Raw salmon can contain harmful bacteria, such as Salmonella, that can be transferred to the tomatoes.
Leandra is thawing hamburger patties overnight at room temperature. This allows harmful bacteria to grow on the patties, which can then make people sick.
Mina is using an unclean cloth to wipe a tray that will hold cookies. The cloth could be contaminated with harmful bacteria, which could then be transferred to the cookies.
Jason and Immanuel are not cross-contaminating food. Jason is not touching any food when he scratches his scalp, and Immanuel is cooking the chicken until it is safe to eat.
Therefore, Kim, Leandra, and Mina are contaminating the food.

What is the density of the substance?
The density of a substance is 0.83 g/mL. We know that the density of water is 1 g/mL. It means the density of the substance is less that that of density of water. If the density of substance is less that water then it will float on water's surface.
Density is how tightly packed particles are in a substance. Warm liquid sinks and cool liquid rises. Heat moves through solid, liquid, and gases through convection currents. Substances with a greater density than water will sink, while substances with less density will float.
Therefore, Density is how tightly packed particles are in a substance. The statement is true.

Why do younger people tend to struggle with their emotional intelligence?
Answer:
due to their lack of experience
Explanation:
Younger people tend to struggle more with their emotional intelligence largely due to their lack of experience. Emotional Intelligence is developed through being in the same social situations over and over again, thus learning how to control, manage, and improve your feelings, relationships, and social skills which make up your overall Emotional Intelligence. Since adults have had many more years to be placed in those situations and increase their Emotional Intelligence, then tend not to struggle as much as younger individuals.
