BIOL 1364 LABORATORY EXERCISE 3 ________________________________________________________________________ INHERITANCE OF CHARACTERS Objectives of the Laboratory: i) Determination of the genetic control of seed colour‚ ie how many genes control seed colour‚ what sort of intra allelic (dominance relationship) and interallelic interactions (independent assortment vs epistasis) govern the inheritance of seed colour. ii) Understand the scientific process involved in studying character

Osmosis Lab Report by Evan Gerber Claire Cambron First Lab Report Wednesday 10:30am February 20‚ 2013 Theresa Gburek Abstract The major objective of the experiment was to test the effect of the concentration gradient on the diffusion rate. It was hypothesized that the greater the stronger the concentration gradient‚ the faster the rate of diffusion would be. To test this‚ dialysis tubes were submerged in different concentration fructose solutions. We weighed the tubes at specific

amylase Aspergillus Oryzae and bacterial amylase Bacillus Licheniformis at different temperatures. Maydelis Perez PI 4593042 Florida International University BSC 1010L‚ section UO9‚ March 6‚ 2013 Abstract Enzymes are very specific protein because they contain one active site on their surface that enable the substrate to bind to the enzyme and form the enzyme substrate complex and then release the products. The principal function

Biology Lab Scientific Paper Down syndrome is a condition in which a person has an extra chromosome. Chromosomes are small “packages” of genes in the body. They determine how a baby’s body forms during pregnancy and how the baby’s body functions as it grows in the womb and after birth. Usually‚ a baby is born with 46 chromosomes but babies with Down syndrome have an extra copy of one of these chromosomes‚ chromosome 21. A medical term for having an extra copy of a chromosome is trisomy. Down syndrome

Phelps‚ Biology 205 MW 2:10pm. Unknown Organism Paper The unknown organism tested in the Mesa lab was collected from in between the toes of my puppy‚ Riley. The original culture grown consisted of dozens of visibly different organisms of varying colony colors and growth patterns. I chose to test a smaller‚ red colony for my experiments. Based on its gram reaction and oxygen requirements‚ the following tests were performed to reach my presumptive ID: Test Performed Result Gram Stain +

sing the pipette. 4. Referring to the timer to determine when 1 minute has passed transferred 5 ml of enzyme B into the cuvette and quickly into the sample holder of the spectrophotometer. 5. Recorded the absorption value at the 1 minute mark 6. Started a new experiment by removing the cuvette from the spectrophotometer and clicking the “New Experiment” button to repeat and continue the steps for the remaining pH values. 7. Determined the estimate of optimal pH after the entire experiment for as a result

Labs 4 & 5 Lab Four: Experiment 1 1. At what magnification do you first notice the ragweed pollen? I first noticed it when the magnification is at about 30 2. Which is bigger‚ rhinovirus or E. Coli? E. Coli is bigger 3. Based on the magnification‚ how many of the E. Coli can fit into the same space as the head of a pin? 10‚000 E. Coli 4. About how many red blood cells could fit across the diameter of a human hair. (Again‚ look at the magnification scale)? About 100 blood cells

Pre-lab questions: 1. Algae belong to what Kingdom? They belong to the Kingdom Protista. 2. What are the three types of multicellular algae? The three types if multicellular algae are chlorophyta which are green algae‚ phaeophyta which are brown algae‚ and rhodophyta which are red algae. 3. Are algae autotrophs or heterotrophs? Algae are autotrophs. 4. What organelle allows plants (and plantlike protists) to photosynthesize? The chloroplasts allow plants and plantlike protists to photosynthesize
