Which situations would be most likely to engage the anterior cingulate cortex?
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.
What is the importance of negative chemotaxis
Answer:
Chemotaxis is the directed migration of cells in response to concentration gradients of extracellular signals. ... In multicellular organisms, it ensures that the right cells get to the right place at the right time during development, and plays an essential role in processes such as wound healing and inflammation [2, 3].

Answer:
Light energy is absorbed by chlorophyll. C
Explanation:
Answer:
Light energy is absorbed by photosynthesis
Explanation:
Photosynthesis takes place in two stages: the light-dependent reactions and the Calvin cycle. In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water.
Which of the following is a accurate depiction of primary ecological succession?
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 potential hazards relating to materials handling injuries?
what are the different ways fungal spores can be dispersed?
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.

Answer:
YES NO
Explanation:
Answer the following using directional terms specific to the dentition. a Your canine is _______________________________________ relative to your first molar. b Your third molar is __________________________________ relative to your second molar. c The cheek side of the tooth row is the ______________________________ side. d Your lateral incisors are _________________ relative to your central incisors. e The tongue side of the tooth row is the ____________________________________ side. f Where your opposite tooth rows meet (to chew) is the _______________________________ surface.
Answer:
The correct answer is - a. mesial, b. distal c. buccal d. distal e. lingual f. occlusal.
Explanation:
Mesial is the surface near the midline of the face, In dentistry, the canine is mesial to the first molar which means it is the middle of the face. The third molar is distal to the second molar.
Distal is the backside of a particular tooth in dentistry. The cheek side of the tooth known as the facial surface for the front teeth in dentistry. Lateral incisors are distal to the central incisors. Lingual is the part of the tooth near the tongue. The chewing surface of posterior teeth is also known as the occlusal.

Prevention of Foodborne Illness
Food purchased from the grocery store may contain pathogens that cause foodborne illness. To reduce the risk of illness, follow proper procedures for food preparation and storage.
Drag the appropriate items into their respective bins.
1- Divide large pots of soup into smaller batches before cooling.
2- Use a food thermometer to make sure meat has reached an appropriate internal temperature.
3- Thoroughly wash cutting boards used for cutting raw meat before slicing fresh vegetables on them.
4- Do not use color as an indicator of how well-cooked meat is.
5- Wash hands correctly before and after handling food.
6- Refrigerate leftover food within 2 hours.
7- Thaw meat on the bottom shelf of the refrigerator.
8- Wash fresh fruits and vegetables before preparing and/or eating.
Clean Combat Cross-Contamination Cook Chill
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.
