Can I Predict when Diffusion or Osmosis Will Occur Lab Report

Biology 1406 Lab 6 Problem 6.2 Fall 2020 – YouTube

How did concentration of the syrup solution and the heat of the system relate to the distance

the solution traveled up the pipette shaft? Explain clearly. Was the 10% and/or 30% solution

hypotonic, hypertonic, or isotonic to the liquid in the beaker? How do you know? Is the 10%

solution hypertonic or hypotonic to the 30% solution? How can you tell based on your

experimental results? In the four osmometers, what was the “osmotic pressure” pushing

against? Which of the four osmometers demonstrated the greatest rate of osmosis (or highest

osmotic pressure per unit of time)? Why? Which osmometer demonstrated the lowest rate of

osmosis? Why? Could this experiment demonstrate how trees might get water to the tips of

their highest branches? If so, what would this experiment imply about tree roots

Carbon Footprint and Cycle Reports

Post two or more paragraphs that evaluate whether your carbon footprint impacts the carbon

cycle. In this Discussion, be sure you:

Explain how your carbon footprint relates to the carbon cycle, the atmospheric history of CO2,

and a national or global average **this should reference the state I live in which is Georgia**

State whether you think decreasing your carbon footprint can impact the carbon cycle

If you agree, suggest two ways you can decrease your carbon footprint and explain how these

suggestions will help

If you disagree, provide at least two reasons for your position

PART 2 – DUE SATURDAY:

Rick Perry, a Texas governor, says that climate change is non-existent and that more and more

scientists are challenging the claim that human activity has resulted in global warming (“Perry’s

Global Warming Statements,” 2011). Actor Danny Glover blames the 2010 Haiti earthquake on

global warming and criticizes a climate summit in Copenhagen for failing to create a significant

response to the perils of climate change (Brent, 2010). Politicians, actors, and many other

public figures make science-related statements. How do you know which statements are truly

based in science, and which are not?

Last week, you explored the nature of science and learned about the scientific method.

Knowing the fundamentals of the scientific process helps you to evaluate science-related

information. Obtaining information from reliable scientific sources—which may not always be a

politician or celebrity—is also critical.

For this week’s Assignment, you respond to a scenario that requires you to identify and analyze

scientific facts about global warming. You also describe the carbon cycle processes of

photosynthesis and cellular respiration and relate these to global warming.

To prepare for this Assignment:

Review Section 4.2 Cellular Respiration (pp. 72-78) in Chapter 4 “Body Weight and

Health”in Biology: Science for Life, and focus on the following:

How cellular respiration occurs

How cellular respiration supports the life of an organism

What ATP is and how it functions in cellular respiration

Review Chapter 5, “Life in the Greenhouse” in Biology: Science for Life, and focus on the

following:

What global warming is

How global warming is related to the carbon cycle

How photosynthesis occurs

How photosynthesis supports the life of an organism

How photosynthesis compares and contrasts with cellular respiration

Conduct additional research to identify scientific facts about global warming. (The Optional

Resources section lists articles and websites where you could start your research.)

One fact should address the change in atmospheric CO2. For this information, refer to the

article “Past Climate Change” listed in the Required Resources section.

Consider this scenario:

You are a participant in a city council debate about global warming. During the debate, council

members make conflicting statements about climate change, and most members are unsure

about the sources of their information. The city council members realize that they do not have

the scientific facts on global warming. You have been selected to conduct research on this topic

and submit a report that includes these scientific facts. The council also wants you to explain

the carbon cycle and how it relates to global warming.

The Assignment:

Write a report of two or more pages that presents the scientific facts about global warming and

explains what the carbon cycle is and how it relates to global warming. Your report should

address the following:

Can I Predict when Diffusion or Osmosis Will Occur Lab Report

The Carbon Cycle

Compare and contrast photosynthesis and cellular respiration by answering the following

questions:

How are cellular respiration and photosynthesis alike?

How are cellular respiration and photosynthesis different?

Why are these two processes interdependent?

Scientific Facts About Global Warming

Identify at least three scientific facts related to global warming that include:

How atmospheric CO2 has changed over the last 650,000 years and since the Industrial

Revolution (1850)

How scientists measure CO2 levels

At least two of the primary factors thought to be involved in the observed changes in

atmospheric CO2 levels since the Industrial Revolution

How the Carbon Cycle Relates to Global Warming

Explain how the carbon cycle relates to global warming, describing at least two implications of

climate change for biological systems.

Be sure to cite all references in APA format.

Be sure to support your ideas by connecting them to the week’s Learning Resources and include

science-related terms from the Learning Resources in your Assignment. Your writing should

provide evidence that you understand the terms you include.
