Phenomenon: Miss Westbrook visited family in Aspen last spring. Aspen is in Colorado and has an elevation of 8,000-9,000 feet. T

he Bay Area has an elevation of 0-100 feet. Miss Westbrook’s breathing and heart rate both sped up every time she went hiking or skiing in Aspen. Why do you think this happened?
Hint: Your brain regulates the rate and depth of your breathing to match the needs of your body for 02 intake and CO2 removal.

Breathing rate refers to the number of breaths per minute.

This happened due to the low air pressure in the highest areas of Colorado, which made hard the intake of air.

Air pressure is fewer as the elevation in an area increases. In other words, the air over us is less, so the pressure that it makes is lower.

Miss Westbrook's heart rate and breathing sped up due to the low air pressure that she experimented with when ascending or when skiing in Aspen, which is very elevated. As the pressure is lower, not much air can enter the lungs, so her brain increases the breath rate to obtain the same amount of oxygen that her body had when breathing normally on the Bay. As there is not enough oxygen in her body, the brain also increases the heart rate to match the rhythm of the breath and deliver the scarce oxygen to the different parts of the body.

In conclusion, the increase in the heart and breath rate happens due to the low air pressure in elevated areas that makes our body find ways to compensate for the decrease in the amount of oxygen that our body can take.

Answer:

factors that influenced daily food choices:

  • biological determinants
  • economical determinants
  • physiological determinants
  • physical determinants
  • social determinants
  • behavioral determinants

Explanation:

Social -ecological system is the set of different factors which influence our living styles, our dietary habits, our dress choice etc. on a daily basis. In today's world, everything act is done by people are only based on its popularity or followed by trends. Similarly, our daily food choices are also influenced by the trends and our surroundings in which we live. There is the impact of multiple factors on our daily food choices.

  1. Behavioral factors: behavioral factor is the most important factor which have a huge impact on our daily food choice. An individual health condition, behavior, attitude, work routine majorly influence the food choices. An individual personal preferences, likes and dislikes also influenced his food choices.
  2. Biological factors: these factors can influence individually as well as globally. Hunger, nutrient requirements, condition of safe food, health conditions are the major biological factors which play major role, when it comes to choose daily food. These factors can affect the global food preferences, for example in the pandemic of convid-19 food choice were similar of every individual globally.
  3. Economic factors: availability of food, cost of food, balancing of needs and demands also impacts our daily food choices. If cost are too high of basic food and the  availability is only limited to certain people, it automatically impacts on the food choice of an individual.
  4. Social Factor: when we talk about social factors these are the group of different small factors like culture, work environment, school, colleges, religious preferences, friends circles, demographic conditions etc. our daily food choices are mostly based on the social factors because our likes and dislikes, meal patterns, our preference of food (cooked, raw, packages, cooking style etc.)  Everything based on the impact of the surroundings. In schools and colleges, students are bound to eat what is available or what their friends prefer to eat. Religious backgrounds always choose as per their rulings. Traditional foods, cultural heritages also an impactful factor for our daily food choices.
  5. Physiological factors: mental health condition are also one of the important factor which can not be neglected when we choose our food to eat. A healthy individuals preferences will always be different from a sick person.

Social-ecological model can help us with our daily food choices by giving us the  knowledge of the factors and its healthy impact on our food choices which can lead us to a healthy life and prosperous environment. Smart choice not only make us health but also make the environment healthy for our lives.

WILL GIVE BRAINLIEST!! PLZ HELP ASAP!!
Nutka1998 [239]

Answer:

A) The outcome of the experiment is that accumulated best in section C. This is because 64 fish were in this section which is the largest amount.

B) one variable that was uncontrolled was that fish were not forced to go into a certain section. They had a chance to accumulate by themselves. If this was controlled, fish wouldn’t be able to adjust by themselves, they would be forced in a section they might not accumulate well in. Another uncontrolled variable would be amount of food you give them. This affects the result because if you don’t feed them, they will die. If you feed them too much, they over eat and die. C) The temperature can affect the physiology because if it is too cold for the fish, they will go to another section until they are warm. If it is too hot for the fish, they will go somewhere cooler.
