The constant turnover of body tissues requires the ______ supplied by carbohydrates, proteins, and lipids
Lera25 [3.4K]

The constant turnover of body tissues requires the <u>chemical energy </u>supplied by carbohydrates, proteins, and lipids.

<h3> What is Chemical energy?</h3>
  • The bonds of chemical molecules contain energy.
  • Exothermic reactions are those in which chemical energy is released during the reaction, frequently in the form of heat.
  • Some of the heat energy needed for a reaction to continue can be stored as chemical energy in newly created bonds.
  • The body transforms the chemical energy in food into heat and mechanical energy.
  • At a power plant, coal's chemical energy is transformed into electrical energy. Through the process of electrolysis, the chemical energy in a battery can also generate electricity.

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.

Why does a female’s cervix dilate prior to delivering a baby?
cluponka [151]

Effacement: The cervix – which is normally long and thick, measuring about 1-2 inches, starts to get shorter and thinner. This process is known as effacement. As the cervix gets more and more effaced, it gets shorter and shorter and “pulled up” into the lower part of the uterus.

Dilation: At the same time, the cervix softens and begins to open up – known as dilation. This widening, allows a smooth passage for the baby’s head and the rest of the body from the uterus into the vaginal canal.
