Phylum Chordata: Sapajus apella body structure, covering Bearded capuchins have forward facing eyes meaning they obtain binocular vision. These primates as other anthropoids and huans have stronger bones above the eye socket which creates less strain for chewing foods, allowing more time for the carbohydrate digestive enzymes to continue break down foods. The skull of the capuchin is large and domed to protect the brain. The capuchins’ four limbs contain 5 digits for each, i.e. fingers and toes

Introduction: For my project, I tested which ratio of baking soda and Vinegar would result in the greatest reaction. I also wanted to see if the having more baking soda or vinegar would result in the greatest reaction. My experiments original design was to use a film canister and put baking soda on the lid and the vinegar in the actual canister. Then I would put the vinegar in the canister and clasp it on the lid with the baking soda. Then the canister would launch up because of the reaction. This

Calorimetry Lab Introduction: As heat is released from an endothermic reaction, the heat is absorbed by another substance, as energy, in this case heat, cannot be created nor destroyed. Through calorimetry and enthalpy, the amount of energy absorbed by another substance can be measured using the equation q=mcΔT, with the amount of energy in Joules equaling the mass, specific heat, and temperature change of a substance, as in this experiment, with the heat released from the combustion of the potato

Analysis: The endothermic salts would not even function as hand warmers at all because they take in energy from their energy in the form of heat. This means it will take heat away from whatever is near it. That means, any hands near the endothermic salts will become colder, not warmer. The exothermic salts, which are the salts give off energy, are LiCl, Na2CO3 and CaCl2. The next important consideration is whether they give off enough heat to make sufficient hand warmers. For 10 grams of the salt

1) Demonstrate understanding of the terms atom and molecule. Atom= Smallest Unit of Matter Molecule= 2 or more atoms chemically bonded. 2) Describe paper chromatography. 3) Interpret simple chromatograms. A method used to separate a Solution, using a Paper and a beaker of water. The Substances in the Paper go up depending on their Mass. We can say that a Solution has the same substance as another solution because they form a line of the same height. 4) Describe methods of separation

is the reaction between two or more molecules when they are either mixed with each other or put in close proximity of each other. Two types of chemical reactions are exothermic and endothermic; exothermic chemical reactions release heat as a by-product of the reaction into the area around it, on the other hand endothermic chemical reactions absorb heat during the reaction and make the area around it cooler. In the context of biology a product is anything that is formed as a

Desert animals experience large daily variation in environmental temperature, with high temperatures during the day and low temperatures during the night. What effect do you expect a drop in temperature from 25°C to 0°C would have on the heart rate of an ectotherm (e.g. a lizard) compared with an endotherm (e.g. a fox)? Explain your reasoning? As the Lizard is an ectotherm, when the temperature decreases, so does the body temperature as it depends on external heat sources.This means that an ectotherm

Mass Conservation Within a Ziplock Bag Question Does a controlled (closed system) Ziplock bag experiment demonstrate the Law of Conservation of Mass? Claim According to the Law of Conservation of Mass inside a controlled system, mass cannot be created nor destroyed, only transformed. This statement is accurate, however, a human error occurred when I performed this experiment. According to my data in the Ziplock bag experiment, the information I collected did not support the Law of Conservation of

what is an exothermic reaction and how can we recognize them? Chemistry; types of reactions. Question: What is an exothermic reaction and where can we find them. Thesis: Despite the fact that there are many different types of reactions, exothermic reactions are a category of reactions that give off energy, this is what makes them so dangerous as well as interesting. It is also what allows them to put on the best show. To start things off lets go over what a chemical reaction is. A chemical reaction

Gas Equilibriums: examples of Reversible Reactions Q1. Identify the general chemical and physical characteristics of gas equilibriums as a group. Explain the forward and reverse reaction mechanisms. Use nitrogen dioxide and hydrogen iodide as examples and explain how equilibrium is reached. The general chemical characteristic of gas equilibriums is when the concentrations of reactants and products do not change with time. This is known as the state of reversible reaction. At this state, pressure
