In conclusion‚ the purpose of the lab Bird Adaptations was to act as a bird using different tools as a beak‚ and try to collect as many items as you can at each station in 15 seconds. Overall‚ the data collected throughout this lab supported each of my hypothesis. The data shows that certain “beaks” worked better than the other at collecting food. For example‚ the data shows that for the Seeds Station the tweezers worked best with an average of 9.3 pieces of food‚ the straw worked best for the Nectar

Biology 10 Vinegar Eel Lab Adam Dorner 1) The most toxic metals were silver‚ lead and iron‚ all killing the eels in under four minutes‚ with silver taking only 1 minute and 40 seconds to kill the eels‚ and only 13 seconds to make the eels stop forward motion. Strontium wasn’t effective as after 5 minutes of exposure to it‚ the eels hadn’t died or stopped forward motion. 2) a) The accepted toxicity varies from metal to metal. The accepted toxic level of lead is 0.0012 parts per million‚ however

structures and properties of amino acids know the groups of amino acid What are amino acids? Amino acids are molecules that when combined with each other proteins. Amino acids contain a central tetrahedral carbon atom (α-carbon) amine group‚ carboxyl group‚ R-side chain The R-side chain determines the different amino acids There are 20 common amino acids Amino acids can join via peptide bonds Several amino acids occur only rarely in proteins Some amino acids are not found in proteins 3D

Amino acids are the building blocks of proteins. Amino acids bind together to form polypeptide chains‚ and these polypeptides fold and coil together into specific conformations to form proteins. There are 20 different amino acids‚ each amino acid consisting of four distinct partners. The first is a carboxyl group. A carboxyl group has very weak acids that are able to donate hydrogen ions to biological reactions. The second partner is the amino acid group. Amino acid groups act as the base which‚

Homeostasis is crucial for normal cellular function. Acid-base homeostasis is the part of human homeostasis and refers to the balance between the production and elimination of H+ hydrogen ions (pH) within the body fluids (William‚ Simpkins‚ 2001‚ p.236).

Vol. 1 ACETIC ACID 115 ACETIC ACID 1. Introduction Acetic acid [64-19-7]‚ CH3COOH‚ is a corrosive organic acid having a sharp odor‚ burning taste‚ and pernicious blistering properties. It is found in ocean water‚ oilfield brines‚ rain‚ and at trace concentrations in many plant and animal liquids. It is central to all biological energy pathways. Fermentation of fruit and vegetable juices yields 2–12% acetic acid solutions‚ usually called vinegar (qv). Any sugar-containing sap or juice can

A carboxylic acid is an organic acid characterized by the presence of at least one carboxyl group. The general formula of a carboxylic acid is R-COOH‚ where R is some monovalent functional group. A carboxyl group (or carboxy) is a functional group consisting of a carbonyl (RR’C=O) and a hydroxyl (R-O-H)‚ which has the formula -C(=O)OH‚ usually written as -COOH or -CO2H. Carboxylic acids are Brønsted-Lowry acids because they are proton (H+) donors. They are the most common type of organic acid. Among
