Describe the role of each of the following mechanisms in determining an individual’s eating habits and body weight.• Biological
alina1380 [7]

Answer:

Explanation:

1. Biological Mechanism: This are things like hunger, appetite and taste of the individual. Every individual is unique and one's hunger and appetite determines how often and how much they eat respectively. The higher these are, the more likely they are to consume calories. The taste is even more relevant as it speaks to what kind of food the individual likes, is it high calorie or low? Is it fat rich or low fibre? Etc.

Learning Mechanism: This are relevant mostly to students. Studying patterns greatly affect eating habits and body weight. Time of sleep, stress patterns, balanced diet and even regularly missing a meal for a study group directly affects metabolism patterns. For instance, eating breakfast regularly boosts metabolism, and is good for weight balance.

Reinforcement: Certain foods are quite addictive and so reinforce their consumption by adjusting brain chemistry.

Body or Brain Chemistry: Studies done on Obesity have found that some individuals are susceptible to environmental food cues than others due to differences in brain chemistry that make eating more habitual and less rewarding. This means that not only do they eat habitually but that it is less satisfying. This is a major contributor to obesity. These Peculiarities in brain/body chemistry affect people's eating pattern and their weight.

Brain Structure Modeling: Uncontrolled eating is also positively associated with gray matter volume (GMV) of the cerebellum, and negatively associated with the Gray matter volume on the left side of the anterior cingulate cortex, middle cingulate cortex, and supplementary motor areas. What this means is that individuals with more gray matter volume in these areas of their brains are more presdusposedto excessive eating habits and this might lead to weight problems and it's related health risks.

Genetic Factors: These factors are genetic predisposition to eating disorders, genetic influence on taste, meal selection and appetite processing.

These also influence how much the individual ends up eating and what type of food they eat.

Cultural Factors: This include type of food found in one's culture, polite eating habits there, the ingredients used for cooking said culture. It also encorporatea the individual's class as food poverty is known to exist affecting about 14 million people. There's also available and affordability of healthy food options. This affects both eating habits and weight as less healthy junk food are more likely to be calorie dense.

PS: The eating pattern and body weight factors are closely correlated as the eating pattern explains what the weight situation might mirror.

Choose the best experimental design to test the question “Does the gender of mice affect the time it takes to learn mazes?”
FrozenT [24]
In making an experiment their are two types of variable that should be consider, one is the dependent variable and the other one is the independent variables. I the question that dependent variable would be the result or the effect of the gender of mice and the independent is the ways in determining it. So the variables should be fair if you want your result to have no bias. Thus the answer would be letter B. because it has the same variables but different in gender
