Biology Summer Task Our digestive systems contain glands. These glands produce enzymes. Enzymes are catalysts. Catalysts make chemical reactions happen quicker and easier. Digestive enzymes help us to break down food easier. Our bodies make lots of different digestive enzymes. Each enzyme breaks down a particular food. When an enzyme has broken down one food molecule‚ it can then break down another molecule of the same kind. It can do this over and over again. It makes the reaction happen without

Alcohol Lab Data Conclusion Objective: The objective of this lab was to find the concentration of an unknown alcohol solution. Procedure and Data: We found the masses of 10.00 mL of each of the known concentrations of alcohol (minus the beaker mass) by placing the beaker onto the scale‚ zeroing the scale‚ and then pouring alcohol into the beaker‚ repeating for each different concentration solution. Then‚ using the same method‚ we found the mass of 10.00 mL of the unknown concentration. We recorded

Nicole Perry 7.06 Immune System Lab Report Thoroughly washing your hands can be one of the best ways to prevent the spread of pathogens that cause illnesses. Our bodies have several lines of defense to fight infections. It is very important to do what we can do to avoid the pathogens from entering our system in the first place. Our hands pick up microscopic pathogens from objects that were touched by people who may not have washed their hands very well. When we forget to wash our hands or don’t

Conclusion In this experiment I tested different light intensities. I tested a normal fluorescent light bulb‚ a 100-watt light bulb‚ a 25-watt light bulb‚ and a 15-watt light bulb. I was surprised to find that the control plant grew the most at 135 mm. The 100 watt plant grew the least at 0 mm due to the fact that it fried the plant. The 25 watt plant grew the next highest at 120 mm. The 15-watt light bulb grew tall fastest‚ but then slowed down and stopped at 98 mm you would want to use this

Fan Cart Lab We did a fan cart for our physics class the other day. To set up the lab first‚ we measured the effect of the mass of the fan cart on the acceleration of the cart. The mass of the fan cart was the independent variable and acceleration was the dependent variable. We kept the speed of the cart on medium‚ and calculated the acceleration and motion. As a result‚ we had figured out that the bigger the mass the slower the acceleration‚ as we all should have known. To calculate this we used

The structures and functions of organs determine their relationships within body systems of an organism. Homeostasis allows the body to perform its normal functions. Explain how the circulatory system (heart‚ arteries‚ veins‚ capillaries‚ red blood cells) transports nutrients and oxygen to cells and removes cell wastes. Describe how the kidneys and the liver are closely associated with the circulatory system as they perform the excretory function of removing waste from the blood. Recognize that kidneys remove nitrogenous wastes

Chapter 3 – The Policy Making Process: Decision-Making Activities‚ pp. 28-50. The Policy Process: How Policies Are Made The study of how policies are made generally considers a series of activities‚ or process‚ that occur within the political system. These processes together with the activities involved and likely participants may be portrayed as in Table 3-1 pp. 29. • Problem Identification • Agenda Setting • Policy Formulation • Policy Implementation • Policy Evaluation Problem

Rat Dissection Prelab 1. Is your left like your right side? It should be similar to your right but there can be differences like if damage was done to one side or if one side was mutated and disfigured. 2. Name an animal that doesn’t have a left and right side. Snakes don’t have a left and right side but there is an interesting study about that which is that Adult snakes (16 of 20 snakes) preferred to coil in the clockwise direction. Many female snakes (15 of 20 snakes)‚ but few male
