Clean Combat Cross-Contamination Cook Chill

Answers

Answer:

1- Chill

2- Cook

3- Combat Cross-Contamination

4- Cook

5- Clean

6- Chill

7- Combat Cross-Contamination

8- Clean

Explanation:

A foodborne illness (also known as food poisoning) is an illness caused by eating contaminated foods by harmful microorganisms such as bacteria (e.g., Escherichia coli), viruses, parasites, and/or toxins (e.g., mycotoxins) contained in foods. Some of the most common symptoms of food poisoning include vomiting, nausea and diarrhea. Foodborne illnesses are generally caused by improper practices in the home kitchen, i.e., improper handling, preparation and food storage. Cross-contamination refers to the transfer of harmful microorganisms/toxins from one substance to another. The most common contributing factors to cross-contamination include equipment-to-food contamination, food-to-food contamination, and people-to-food contamination. The most important habit to prevent cross-contamination is washing hands and foods before eating and cooking. Moreover, cooking foods to proper temperatures can destroy microorganisms/toxins that cause foodborne illnesses. Finally, chilling (at 8˚C or below) and freezing (at -18° C) foods can also protect from food-borne illnesses as many harmful microorganisms cannot grow at these temperatures.

Which situations would be most likely to engage the anterior cingulate cortex?

Answers

Answer:

Which of the following situations would be most likely to engage the anterior cingulate cortex?

A waiter walks over to your table at a restaurant and holds an open menu in front of you.

You walk into the elevator of your apartment building and press the button for your floor.

You enter your classroom and find someone sitting in your usual seat.

A good friend asks you to remind him of your telephone number.

Explanation:

In order to meet the demand of the surrounding environment   by adjusting  the  motor outputs from the brain to the environments ,a part of the emotion control part of the brain( limbic system) called the anterior cingulate cortex is responsible for this.

Anatomically, the limbic system is made up of the primarily the amygdala, hippocampus, thalamus, hypothalamus, basal ganglia and cingulate gyrus.

Based on the this its(anterior cingulate cortex) functions are formation of emotion in the limbic system, and  possessing  of memory and learning.

it is also a major  parts of  of pain networks for pain modulation and perception.

Therefore whenever there is  change in the environment  from the prestored condition in the brain,(e.g the usual seat  in the class room  occupied above) the anterior cingulate cortex adjust the motor input from the brain to adapt to the new environment to take an action,whih in this case  leads to the reclaiming of the seat or any other necessary proactive action.

Which of the following is a accurate depiction of primary ecological succession?

Answers

Answer:

This question lacks options, however, primary succession will be explained for detailed comprehension.

Explanation:

Ecological succession is the gradual series of changes that occurs in an ecosystem, charging it's structure and composition over time. It is of two types namely; primary and secondary successions.

Primary succession is characterized by the "LACK OF NO SOIL". It begins on a barren piece of land e.g rocks, with no form of life previously known to colonize the area. In primary succession, the barren land is first colonized by organisms such as lichens etc., which are collectively regarded to as PIONEER SPECIES.

what are the different ways fungal spores can be dispersed?

Answers

Answer:

Explanation:

The spores of some fungi are dispersed in water or on the surface of water. The chemical composition of the wall of these spores makes them "non-wettable" so they won't sink. The spores are carried along on the surface of the water like little boats. Water in the form of raindrops can disperse spores in a different way. While gravity is not a primary means of spore dispersal, evolutionary adaptations have been required of many fungi to overcome gravitational effects for effective spore dispersal. SPORE DISPERSAL BY WIND Dispersal of fungal spores by wind is by far the most common method for terrestrial fungi.
