Lab: exercise and homeostasis lab report
if anyone has done this pls help
ill give brainliest
Answers
Introduction:
The question that was trying to be answered in this lab was “How does exercise affect a person’s heart rate, breathing rate, and perspiration level?” Based on this question, the hypothesis that was formed was “If effects of exercise and exercise are related, then exercising will increase heart rate, breathing rate, and perspiration level”.
What is homeostasis?Homeostasis refers to the mechanism of the body to maintain a stable internal environment instead of changes taking place in the external environment.
Homeostasis in the body is maintained through three vital organs, as mentioned before, the kidneys, liver, and brain. These regulate the temperature, iron content in our blood, retention, and production of energy and overall blood composition. This was helpful because the whole lab report was based on homeostasis and the effect that it had on exercise.
Materials and Methods:
1. Materials:
a. People to exercise
b. A clock or stop watch
2. Procedure:
Choose one volunteer to complete jumping jacks at a pace that can be maintained for eight minutes. Make sure the volunteer is inactive for a few minutes before the experiment begins.Measure the heart rate by taking his or her pulse, you can do this one of two ways: Radial Pulse, Carotid PulseMultiply the number of beats in 15 seconds by 4 to calculate the beats per minute. Record the data in the table below the 0 minutes box.Measure the person’s perspiration level from 0 to 5: (0 = none; 5 = droplets dripping down the face). Note this observation in the table. Have the volunteer do jumping jacks for 2 minutes. After 2 minutes, measure the heart rate, breathing rate, and perspiration level (refer to steps 2 through 5), and record the data. Measure the pulse, breathing and perspiration levels as quickly as you can so that the volunteer can resume exercise. Do not have volunteer wait while you do the calculations and enter the data. Repeat step 6 three more times (remember, 2 minutes each at a time, totaling 8 minutes) and record your data at each point. After the final recording of the dependent variables, wait one minute with the volunteer at reset. Then measure all of the variables again. Record this data under the “9 Time (Min.) Box”.Analysis:
There is an increase effect of exercise over time on the circulatory and respiratory systems, as shown in both Table 1 and Table 2. As the students began their exercise in two-minute intervals, their heart rates increased on average from 73 beats per minute to 115 beats per minute. Shawn’s individual heart rate began at 84 beats per minute, and after lifting 5-pound weights for 8 minutes, his heart rate increased to 114 beats per minute . Also, his breathing rate showed an increase from 36 breaths per minute to 44 breaths per minute.
Based on this data shown, the amount that you exercise does effect the circulatory and respiratory systems by causing a, on average, dramatic increase in beats/breath per minute in the measured variables.
Conclusion:
According to the data collected, the hypothesis that was developed at the beginning of the experiment: “If effects of exercise and exercise are related, then exercising will increase heart rate, breathing rate, and perspiration levels”; was accepted . Based on the data shown our individual group charts and the class averages, the effect that exercise has on the respiratory and circulatory systems is that it develops an increase in heart rate (Start: 73/ Finish: 115), breathing rate (Start: 38/ Finish: 56), and perspiration levels (Start: 0/ Finish: 1).

13. Which method for producing electricity has had the most negative impact on the
atmosphere?
A burning fossil fuels
B. controlling nuclear fission
C. harnessing wind with windmill farms
D. using hydroelectric dams to block rivers
Helpppp please
Answers
Answer:
The answer is A.
Explanation:
One of the downsides to electricity is the way it is generated. Usually, electricity was generated through Coal which as a fossil fuel was pivotal in releasing large amounts of carbon dioxide into the atmosphere.The method for producing electricity that has had the most negative impact on the atmosphere is A) burning fossil fuels.
What is the consequence of burning fossil fuels ?Burning fossil fuels, such as coal, oil, and natural gas, releases large amounts of carbon dioxide and other greenhouse gases into the atmosphere. These gases trap heat in the Earth's atmosphere, leading to global warming and climate change.
In addition, burning fossil fuels also releases other pollutants, such as sulfur dioxide and nitrogen oxides, which can contribute to acid rain and other environmental problems.
While all methods of producing electricity have some impact on the atmosphere, burning fossil fuels has had the most negative impact due to the sheer amount of greenhouse gases and other pollutants that are released during the process.
While there are efforts to reduce the negative impacts of burning fossil fuels, such as developing cleaner burning technologies and transitioning to renewable energy sources, the continued use of fossil fuels for electricity generation remains a significant challenge for addressing climate change and reducing air pollution.
In addition to greenhouse gas emissions, burning fossil fuels also produces other pollutants, such as sulfur dioxide and nitrogen oxides, which can contribute to acid rain and other environmental problems.
Therefore, extraction, transportation, and storage of fossil fuels can also have negative environmental impacts, such as oil spills, groundwater pollution, and habitat destruction.

A scientist has measured a decrease in fish populations in a lake. He suspects that acid deposition has caused the fish to die. By what mechanism could acid deposition have killed the fish
Answers
Acid deposition has caused the fish to die because the mechanism of acid deposition in the lake causes an algal bloom that decreases oxygen levels in the water.
What is Acid deposition?Acid deposition may be defined as the process of formation of precipitation with acidic components, such as sulfuric or nitric acid that plunge to the ground from the atmosphere in moist or dry forms.
Acid deposition also alters the normal pH of the water body which is safe for the survival of the fish population.

O bottom-up processing
o facial feedback
selective encoding
O justification of effort
Answers
o facial feedback
When someone replicates a emotion, they tend to feel it
Nick is smiling even though he does not feel happy and after a short time he feels happier too. This change in mood is due to facial feedback. Therefore, the correct statement is option B.
What is the facial feedback mechanism?Facial feedback is a psychological theory that suggests that the expression on a face of a person can influence their emotions and mood also. Therefore, when a person smiles even when they are not feeling happy, it can trigger positive emotions in the brain that change in mood.
Nick is smiling even though he is not feeling happy. Therefore, this act of smiling can trigger positive emotions in his brain and changes his mood because of the facial feedback mechanism.
However, bottom-up processing is the processing of sensory information from the environment to create a perception, while selective encoding is a process of selectively attending to and encoding certain aspects of a stimulus while ignoring others.
Therefore, Nick is smiling even though he does not feel happy and feels happy after a short time due to facial feedback.
