I WILL GIVE BRAINLIEST IF YOU ANSWER ALL OF THE QUESTIONS !!! I NEED IT DONE TODAY Evolution and Natural Selection Lab Report

Instructions: In the Natural Selection lab you will explore adaptations that help organisms survive best in a particular habitat. You will observe how changing a factor in the environment will impact the organisms that live there over time. Record your observations in the lab report below. You will submit your completed report.

Name and Title

Include your name, instructor's name, date, and name of lab.

Objective(s)

In your own words, what was the purpose of this lab?

Hypothesis

In this section, please include the if/then statements you developed during your lab activity. These statements reflect your predicted outcomes for the investigations. You will investigate two different versions of the tree environment as it changes over time: light-colored bark and dark-colored bark. Be sure to list your hypothesis for each environment below.

Example: If I investigate the light-colored bark environment, then I will observe an increase in the light-colored peppered moths over time.

Hypothesis for the light-colored bark:

Hypothesis for the dark-colored bark:

Procedure

The procedures are listed in your virtual lab. You do not need to repeat them here. Please be sure to identify the test variable (independent variable) and the outcome variable (dependent variable) for this investigation.

Reminder: The test variable is the item that is changing in this investigation. The outcome variable is the item that you are measuring in this investigation.

Test variable (independent variable):

Outcome variable (dependent variable):

Data

You will investigate both environments. Record your data for each trial of that environment in the data charts below.

Conclusion

Your conclusion will include a summary of the lab results and an interpretation of the results. Please write in complete sentences.

What caused the tree bark to become darker?

In the lab simulation, which color peppered moth was able to have the higher rate of survival on the light bark?

In the lab simulation, which color peppered moth was able to have the highest rate of survival on the dark bark?

During the Industrial Revolution, explain what caused the population of light-colored peppered moths to decrease and the population of dark-colored peppered moths to increase over time. Be sure to include how the ability to survive and reproduce impacts the process of natural selection.

Predict which color peppered moth would have a better chance of survival in your neighborhood? Explain why.

Objective(s)

In your own words, what was the purpose of this lab?

I believe the purpose of this lab is to see how much our society is evolving.

Conclusion

Your conclusion will include a summary of the lab results and an interpretation of the results. Please write in complete sentences.

What caused the tree bark to become darker?

What caused the tree bark to become darker is the time of the day the darker it is the darker the bark is.

In the lab simulation, which color peppered moth was able to have the higher rate of survival on the light bark?

The light-colored moth had a higher rate of survival than the dark-colored moth.

In the lab simulation, which color peppered moth was able to have the highest rate of survival on the dark bark?

The dark-colored peppered moth had a higher rate of survival than the light-colored moths.

During the Industrial Revolution, explain what caused the population of light-colored peppered moths to decrease and the population of dark-colored peppered moths to increase over time. Be sure to include how the ability to survive and reproduce impacts the process of natural selection.

What caused the population of light-colored moths to decrease and the population of dark-colored moths to increase over time was because the dark-colored moths could camouflage themselves on the dark bark trees and the light-colored moths couldn’t protect themselves from predators because they had no where to hid.

Predict which color peppered moth would have a better chance of survival in your neighborhood? Explain why.

I believe that the dark-colored peppered moth would have a better chance of survival than the light-colored moths because there is mainly dark bark near my neighborhood instead of light-colored peppered moths.

Explanation:

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
