flat =Cell size lab:= 1. Compare and contrast the three cubes after they were sliced in half. there are all different sizes and they water only got half a cenimeter for each 2. Which "cell" seemed to be most and least efficient at getting outside substances into the cell? Explain. the small one seemed to be efficent while the big one was the least. 3. Which of your calculations seems to explain what you observed in your cell models? Why do you think so? 4. Speculate on a relationship between cell size and efficiency. Your statement should resemble a hypothesis. (Remember: Use an If....., then..... statement.) if the cell is bigger than than it will take longer for substances enter the cell. =Protist lab:= hree interesting facts

2.These plants can escape into the wild and some variants are considered an invasive species. 3. They provide a useful habitat for small fish and crustaceans, but because they propagate by breaking off and floating away, they can often choke up a pond.

Three interesting facts 1.It is osmosis & diffusion.

In plain water, cells take up water, swell & look larger and pale. 2.In saline water (if hypertonic=high concentration), cell will leave water 6 shrink and look dense. In normal saline (0.9% NaCl), cell usually remain as their original size

= Are you what you Eat? =

=Bio molecule food results= Gatorade simple sugar: Positive starches: Positive Proteins: Negative Fats and oils: Negative
 * 1) It means to me that your body does what it suppose to do and why it is important to me is your body tells you when you are hungry and what it craves. Your body tells you how you will react to the bodies hunger and your body could get sick without food. When you feel sick it makes result into the hunger in the stomach it also your body can control your whole body in my perspective it also helps with the brain.
 * 2) First question I have is why do all the commercials on TV that try to persuade you in to healthy foods?
 * 3) Why are foods so good for you?
 * 4) Could you explode from eating to much?

= Enzyme Lab = = Photosynthesis scientist =
 * Name of substances || simple sugars || Starches || Proteins || Fats and Oils ||
 * Apple || positive || negative || negative || positvie ||
 * Gatorade || positive || positive || negative || negative ||
 * Liver || positive || negative || positive || positive ||
 * Apple Juice || positive || Negative || Negative || Negative ||
 * 1) Your data from the food you tested.
 * 2) Research the biomolecules (nutritional information) that are found in the food that you tested. Which tests should have been positive (present) or negative (absent) based upon your research? Simple sugars in Gatorade are a 20flz bottle of Gatorade has 34g of sugars. Starches in Gatorade 34g.
 * 3) Compare foods of your choice that you and others tested (for example, looking at all fruits or foods that contain carbs). Be sure to include foods that you did not test that others in class tested. Discuss the results of the tests (the biomolecules that make up these foods.) Make a statement about the biomolecules in the foods, what happens to these foods in your body (what they are used for), and any other information you found interesting through research. Remember to include a link to your sources of information.
 * 1) Write the equation for the breakdown of hydrogen peroxide.
 * 2) How did the amount of reaction change between room temperature, warm, and cold hydrogen peroxide?
 * 3) What large group of biomolecules (carbohydrate, lipid, or protein) does catalase belong to? What do members of this group have in common?
 * 4) Is it possible to reuse biomolecules like catalase? Explain.
 * 5) What happens to an organism if biomolecules like catalase become useless? Explain


 * 1) van Helmont: he thought the water was most of the mass of a plant carbon dioxide makes up mass of a plant.

2. Priestley: best remembered for his discovery of the gas that would later be named "oxygen,"

3. Ingenhousz”: He proved that sunlight was necessary

4. Calvin: came up with the dark recation media type="custom" key="25086144" =Flipbook= media type="custom" key="25199902"

=Tay-Sachs disease=


 * 1) Chromosomal mutation
 * 2) Speech and swallowing difficulties
 * 3) 1 out of 3 in 10 years
 * 4) when one of the HEXA genes are not working right

=Intro Activity to Fuel economy:=
 * 1) the taxes in the economy in a given country are the same because if you look at the graphs the compare in some way.
 * 2) A car
 * 3) conclusions we can draw is that all over the world there is probably a car being used
