1. Reflect on the autotrophs and heterotrophs in your Ecocolumn by answering the questions below: Two autotrophs that can be found in my Ecocolumn are the anacharis located in the aquatic environment and the pinto bean plants located in the terrestrial environment. Two heterotrophs found in my Ecocolumn are the ladybugs that live in the terrestrial region and the guppies which are in the aquatic region. Data that we recorded from our Ecocolumn demonstrated that both the autotrophs and the heterotrophs

Jack Ferguson 12 May 14 Lab #8 In cryptography, encryption is the process of encoding messages in such a way that eavesdroppers or hackers cannot read it, but that authorized parties can. In an encryption scheme, the message or information (referred to as plaintext) is encrypted using an encryption algorithm, turning it into an unreadable ciphertext . This is usually done with the use of an encryption key, which specifies how the message is to be encoded. Any adversary that can

Lauren Sullivan Plants Imperfections Abstract The purpose of this experiment was to plant different crosses and observe the different phenotypic ratios the plants present. The procedure of this experiment was plant six different crosses and water them correctly so that we could observe the different phenotypes and compare them to Mendel’s proposed ratios. Mendel, who had studied peas, did a similar experiment and came up with specific ratios that a monohybrid and dihybrid cross should show. His

Title: Counting the Number of Yeast Cells in a Suspension using Haemocytometer Objective: To estimate the number of cells of yeast per mm3 in five different dilutions of yeast suspension. Introduction: Biologists often need to count the density of cells in a liquid. “Density of cells” means “the number of cells per unit volume of liquid”. For example, they might want to find out the density of red blood cells in blood plasma, the density of bacteria in milk, or the population of Paramecium sp
