2. Will you be available in roughly 4.5 hours (8pm EST)?
3. Are you able to complete the assignment in 1-1.5 hrs?
Bio I Assessment
List the two bio-mes that are dominated by grasses. What are the abiotic factors that control the dominance of grasses in these bio-mes?
1.Hypothesize: generate a hypothesis in reply to Mary’s questions. You do not have the full picture yet, but what do you predict you will find? What exactly is a blight?
Where do you think the blight that killed off the chestnut trees in eastern North America came from? Why are some chestnuts still alive today? And why are they not as big as they once were decades ago?
Invasive species
Find an invasive species from where you are from and write about it.
Where is it originally from? What impact is it having in your area? What are people trying to do to deal with it?
Low Carb vs. Low fat Diets
Watch the video below. Why do you think it is that quick weight loss does not lead to long term weight loss?
In the article below, several types of diets are analyzed. Choose one and discuss:
What do you see in the study that leads to its credibility or indicates the possibility that it might not be a well conducted or unreliable study? Do you have an idea what the “best” diet for weight loss might be?

1 Lab Online –Summer 2020 Lab 4: Biological Molecules At–Home Experiment Iodine Test and Lipid Test Instructions Items needed:
•Oil Vegetable, canola, olive, etc.Just clean and in liquid form
•Water Can be bottled or from the faucet.
•Sugar or Sugar Substitute Whatever type of sugar, sugar substitute, or honey you have on hand.Mix at least a teaspoon with ¼cup warm water.Make sure granules dissolve.
•Iodine Small bottle,can be found in first aid section at most stores. This is safe to get on your skin, it’s just a disinfectant, but it will stain skin, clothes plastic dishes, white counters, etc.
•1–2 tea spoons of flour, cornstarch, corn meal, or dry instant mashed potatoes, or all if you’re feeling froggy Mix 1–2table spoons of dry substance with ¼cup of warm water.
•Small containers or bowls, at least 6.They don’t have to be clear, but you need to be able to see into them well to see color changes.Glass will work best to prevent staining from the iodine.
•A small piece of food that you pick from your kitchen. This can be a couple pieces of cereal, small piece of cheese, chips, a piece of banana, any food item really.
▪If it’s a dry food, crunch it up well and mix it with 2–3 tablespoons of water.
▪If it’s a fruit or vegetable, you don’t need to mash it up or add water, just make sure it’s peeled showing the interior of the fruit or vegetable.
•1 piece of construction paper, piece of brown paper bag, or cardboard cut into two pieces.These two pieces can be kind of smaller if you can’t find a big piece, 2 inches by 2 inches is really all you need. Lipid Test–Tests for lipids in a liquid.Wet look after drying is a positive for lipids.If the drop dries back to the original color, then it is negative.
Procedure:
1.Get your two pieces of cardboard, construction paper, or brown paper bag.
2.Place a place under each to prevent oil getting on anything.
3.Place a drop of water on one.
4.Place a drop of oil on the other.
5.Let these sit until your drop of water is dry.
6.Which liquid was positive for lipids? You can also try this with salad dressings, marinades, etc.
You will not write a lab report over the lipid test but there will be questions on your Lab 4 Quiz pertaining to this portion and your results.
1 Lab Online –Summer 2020 Iodine Test–Tests for starch which is a polysaccharide. Positive–produces and blue–purple–black color.
Negative–Liquid remains yellow or rusty brown (the color of the Iodine)
Create a table listing all the things you are going to test in the iodine test. This can just be drawn right now then created in word later.List your thoughts, which items do you think will produce a color change? Which do you think won’t produce a color change? What does the color change mean? Why do you assume what you doabout each item? Include your responses in your lab report, even if you were wrong or surprised. Hypothesis: If…then statement. Remember, you want to know which items are positive for polysaccharides.
Be sure to avoid contamination, don’t mix your oil and water with the same tool you used to mix cornstarch and water for example. This could impact your results.
Procedure:
1.Cover the bottom of the bowl or glass with oil, only enough to cover the bottom is needed.
2.Cover the bottom of the bowl or glass with water, same as above.
3.Cover the bottom of the bowl or glass with 50% water and 50% oil, same as above.
4.Cover the bottom of the bowl or glass with sugar/sugar substitute and water mixture.
5.Cover the bottom of the bowl or glass with the flour/cornstarch/cornmeal/potato flake mixture. a.If you want to try multiple of these just do the same and add another bowl with the same steps as above. b.Tip: if using potato flakes, let them sit and soak in the water for at least 10 minutes before adding iodine.
6.Place the random food item you picked from your kitchen in a bowl.
7.Place 2–5 drops of iodine in each bowl, recording your observations as you go. 8.Write your lab report over the experiment you just performed using your experience, data, and what you know about carbohydrates.Pictures of your experiment are always welcome in a lab report!When you are done, using your own knowledge of your sink, liquids can be washed down the sink with no staining if you rinse the sink well immediately. Large pieces are safe to throw away regularly
Coursework/Journal entry
1.) There is a moth in England called the peppered moth. Before Britain’s industrial revolution, these moths were usually salt and pepper colored. Because of their coloring, they blended in well with the tree trunks on which they tended to rest. The coloring helped them hide from the birds that ate them. During the British industrial revolution, industry expelled a lot of soot from the burning of coal into the environment. This soot darkened the tree trunks, and it was noted that black-colored moths were becoming predominant. The idea is that with soot in the environment, black-colored moths fared better than light-colored moths. There is some debate as to whether this is actually the case or not, but for the sake of this question, let’s assume it is.
In your own words, explain the concepts from the four observations discussed in 12.2 using the moth as an example. In other words, how does the moth illustrate the first observation, the second observation, etc.?
2.) Whether you “believe” in evolution or not, why is it important to be knowledgeable about Darwin’s theory? How might genetics and evolution apply to our modern society when we consider the differences between people? Should we stratify people based on intelligence or other specific qualities? Have you observed traits in your parents that you do not like and see them in yourself? (You do not have to be specific about personal issues but can write about issues in a general sense.)
Discuss the current concerns regarding sedentary behaviour in the adult UK population.
Within your answer, critically evaluate how the Biopsychosocial Model can be used to understand the factors that influence physical activity levels.
Explain the role of genomics in conservation biology.
