Question: Why would sensing and responding to vinegar be important to an organism? -It could train them to respond to certain smells and respond in a certain way. How would natural selection affect an organism’s ability to sense and respond to this stimulus? -The organism depends on its ability to sense and respond. The organisms could compete for water or hydration. What other types of stimuli would be important for the organism to respond to? - An organism that is used to light is

Bacteria Lab Write-Up Jianna Liu P8 Purpose: The purpose of this lab is to find out which substance‚ alcohol‚ antibacterial soap‚ water‚ or hydrogen peroxide‚ is the best at preventing the growth of bacteria. Hypothesis: Antibacterial soap will be the best because soap is a substance that people use to wash their hands because it takes away the germs. Even the name‚ antibacterial soap‚ suggests that it fights off bacteria. Hydrogen peroxide is second because it is used

The Mollusks Tori Johnson Kylie Pocrnich December 17‚ 2012 Zoology In this lab‚ my partner Kylie and I will be examining the internal and external features of the clam. “Like all mollusks‚ a clam has a mantle which surrounds its soft body. It also has a muscular foot which enables the clam to burrow itself in mud or sand” (Miller and Levine). Clams are mollusks with two valves also nickname the bivalves. Clams are mostly marine animals however; the clams we will dissect are freshwater clams. Adult

AP Biology Lab 1 Ross Lordo Introduction Questions 1. The solute potential would be -2.48. If the concentration inside the cell is .15 M‚ then would diffusion out of the cell and into the solution of .1 M. This is due to water potential and the tendency for water to move from areas of high water potential to low water potential. 2. The turgor pressure must be equal to the water potential if there is no net diffusion. The cell and environment have reached equilibrium and the movement of water

IB Friction Lab Write Up 3. The slope of my graph represents the constant value for myu as the Normal Force and the force of friction are constantly changing. 4. The kinetic slope is the biggest by far because it represents the less coefficient of friction it has to overcome to move easier. 5. According to my data table‚ an increase in weight always‚ without fail‚ creates a greater force of friction. 6. An increase in weight does not affect the coefficient of friction by also increasing

Lab Report Title: * Color reaction of starch when mixed with Iodine solution Introduction: Statement: * How would the varying solutions react when introduced with the Iodine solution? Hypothesis: * If a solution is rich in starch then it will react with iodine solution and change to a bluish-black color (looks Brown) Materials: Items: * 8 test tubes‚ pipet‚ iodine‚ onion juice‚ potato juice‚ sucrose solution‚ glucose solution‚ distilled water‚ fructose solution‚ starch solution

AP Bio p. 6 December 8‚ 2011 AP Biology Lab 5: Cellular Respiration Introduction/Lab Objective: In this lab we are testing how the process of cellular respiration is affected by temperature‚ and also how it is different between germinating and non-germinating peas. Cellular respiration is a catabolic process (breaks down organic material into usable cell energy) that produces ATP. The electron receivers are inorganic. Cellular respiration releases energy from organic material through chemical

Evolution Lab A. 1. a. The default value of 20 cm of rainfall is relatively low compared the range that the island may receive‚ which is anywhere between 0 cm to 100 cm. b. From an average of 20 cm of rainfall I would expect more hard seeds to be produced. 2. a. The beak size of 12 mm is relatively shallow compared to the available range from 10 mm to 30 mm. b. The shallow beak size of 12 mm is not suited for the hard seeds that are available because of the low rainfall of 20 cm.

Starch is a type of Carbohydrate that’s made from thousands of glucose units. Simple sugars are the basic units that make up starch. Carbohydrates provide us with energy so that we can carry out our daily routines. Our body then digests it into glucose so we can have energy to do that. Saliva is a form of chemical digestion that is in the mouth. Amylase is an enzyme that catalysts the breakdown of starch into sugars. Amylase is present in human saliva‚ where it begins the chemical process of digestion

displacement‚ the volumes of the paper clip samples were measured and the masses were obtained by using an electronic balance. Each mass and volume was unique to their sample so by using their values‚ density was used to identify substances in the lab. After conducting the experiment‚ the results showed that there was a positive slope between the different paper clip samples’ masses and their volumes. It was concluded from this pattern that density is an extensive property. Introduction In science
