Define the following solutions: hypertonic, hypotonic, isotonic.

Background information can be found in the Student Workbook as well as the OpenStax textbook, or online (just be sure to cite your references in the text as well as provide the citiation at the end of the report).
This should include:
What is osmosis?
How does osmosis differ from diffusion?
What is concentration?
What determines the direction of movement of molecules?
What is osmotic pressure?
What is a semipermeable membrane?
Define the following: solute, solvent, solution
Define the following solutions: hypertonic, hypotonic, isotonic.
How do the different solutions affect a cell?Explain why/how.
What is the purpose of the activity?
For methods tell me what the program was that we used. Then breifly describe what you are manipulating and provide the variables that you used for each exercise. I would recommend referencing SimUText and providing appropriate citations.
When reporting your results remember that you should provide both a written descriiption and I would recreate any tables from the student workbook and include a column for what the results were on the cell.
Your discussion should explain to me why you observed the cell either shrinking or bursting, depending on what your manipluations were for each excercise. Then simply tell me what you learned and how this can be applied to real life applications such as receiving an IV and why it is important to have specific concentrations of molecules in the solution.
Hint: Scientific writting is rather bland… You would simply report what was observed, for example you could say “The cell burst as a result of an influx of water molecules.”; but would not say “As water flooded the cell like middle-school girls rushing the stage at a BTS concert the cell burst like a cosmic explosion leading to the formation new of solo careers.”

Based on a data collected prove why capacity of male higher than female.

Physiology respiratory lab report.
Look at the data entry (provided) to find a hypothesis.
Example: Respiratory volume capacity is higher in males than females. (based on a gender)
some time a hypothesis based on weight high and different categories ,some people smoke so it will be different as well . you can look at the data to see more.
based on a data collected prove why capacity of male higher than female.
A lab report make sure have a title , abstract, introduction material/method, result , discussion, work cited(peer review source)
you can a data in the file I attched that is my group record.

Reflect on your results, and think about these populations in relation to natural selection.

Access PhET Natural Selection Simulation (https://phet.colorado.edu/en/simulations/natural-selection)
Click “Play Button”
Double Click “Lab”
Manipulate variables available in the dashboard of the program to edit traits, selection factors, and environment
Get familiar with the program. Add friends, add a food source/predators, add mutations, etc…
Complete the tasks below and submit the assignment
The paper contains 3 questions and an analysis to be performed. This can be answered by performing the tasks in the sim in the link provided.
________
Task 1:
a) Select dominant and recessive traits.
b) Select for food to be available.
c) Select equator environment.
d) Let the simulation run for a few generations, then introduce the predator factor.
e) Repeat step “d” multiple times.
Question: After running the simulation for multiple generations, what do you notice about the population of bunnies? What is driving the observation you observed? As more and more generations of bunnies are born, are more desirable or undesirable traits being passed on (relate this to fitness: the ability to produce offspring that survive themselves to reproduce)?
Task 2:
a) Repeat steps “a” and “b” from Task 1.
b) Select the Arctic environment.
c) Repeat steps “d” and “e” from Task 1.
Question: After running your second simulation of bunnies, what do you notice about the population in the Arctic environment? Do you notice any differences from your first simulation? Formulate a hypothesis of why you are seeing a difference (or not).
Analysis:
Review your notes from the simulations between the Arctic and Equator simulations.
Reflect on your results, and think about these populations in relation to natural selection.
Question: If you have a population of bunnies with 50% having brown coats and 50% of the bunnies having white coats, would one color of bunnies be more fit in the Arctic environment? How does the survival of the bunnies explain evolution by natural selection?

Antibiotic Resistance Assignment
Here is the link for a video that we’ll watch together about an antibiotic resistance evolution experiment.

In 2016, some researchers in the Kishony Lab at Harvard, built a massive rectangular petri dish the size of a table (usually these are round and about the size of your palm, and we will use many of them in lab this semester) with different amounts of the antibiotic trimethoprim in different sections of the plate. Here is a video of them describing their work on the MegaPlate:
We’ll watch this video and, as a group, discuss, the causes and results of antibiotic resistance, and how this experiment works, and what it taught us about antibiotic resistance in bacteria. If you want to read the paper (not required, but might be interesting), use this link for the .pdf. This assignment will require you to apply your knowledge of evolution, antibiotics, and cell structure to a real-world situation.

Instructions: Answer the questions (I’ll provide them in class) and this is a link (Links to an external site.) for them. Besides the materials provided for the class including videos, textbook, notes, linked papers, Canvas site, you should not need any additional resources and they will only confuse you.

How to write an Introduction section1. Present information that familiarizes the reader with the subject of the experiment. What to include: A well-written introduction should present information about all the topics directly pertinent to the experiment. The Introduction section of the lab exercise provides a brief summary of many of the relevant subjects.How to write: Use well-structured paragraphs beginning with a topic sentence that expresses ideas in your own words. How to organize: Organize the information from the broadest topics that help to establish relevance, to more specific topics pertaining directly to the experiment.

In order to get accurate results, i will multiply each treatment, and put them into different ziplock bags.

to see which moisture levels affect the growth of mold on white bread, and applying the scientific
method. ( I will attach an outline)
The experiment will focus on how moisture influences the growth of mold, and it was conducted on samples of white bread and the growth of mold that is determined by percent cover. To do this experiment, I will divide into 3 groups: bread only, two treatment levels of 5ml and 10ml absorbed into bread. In order to get accurate results, I will multiply each treatment, and put them into different ziplock bags. The percent cover of mold on the samples of white bread with varying moisture levels was collected over a seven day period.
