Transformation Efficiency is Dependent Upon Plasmid Grant Zarrinmakan‚ Berkley Kruschke‚ Erika Lawrence. Wed/Fri‚ D-Block‚ 12-January-2015 Introduction Transformation is the genetic alteration of a cell resulting from the direct uptake of exogenous DNA from its surroundings. By doing this lab‚ we will answer the essential question: What influences transformation efficiency? Although there are many possible influences‚ our hypothesis is that plasmid has a positive influence. To test this hypothesis

AP Biology Photosynthesis Lab Bethany Boyer Due 11/12/14 Lab Write-Up Questions First Experiment 1) The independent variable in this experiment was the presence of CO2 (carbon dioxide). The dependent variable was the speed at which the leaf disks started to float. 2) In the leaf tissue‚ the bicarbonate and light are combining to carry out photosynthesis. This will cause oxygen to collect in the leaf tissue‚ causing it to rise. 3) If we were to boil the leaf disks‚ the reaction would most likely

28/09/12 Grace Masters Woodlice Behavior Experiment Aim: To investigate the effect of light intensity on the behavior of woodlice (Porcellio scaber) in regards to their change in speed. Variables: Variable How can it be controlled? (IV) - Light intensity - The light intensity will be controlled by the knob on the lamp throughout the experiment. In addition‚ the light intensity will be controlled by closing the windows and doors in the classroom as well as turning

LSM 8.5-1 Student Worksheet Lab Exercise 8.5.1: Hormone Levels During the Menstrual Cycle How do hormone levels regulate the female menstrual cycle? Use the following experimental data to analyze hormone levels during the menstrual cycle. Analysis 1. Gonadotropic hormones regulate ovarian hormones. Study the feedback loop shown in Figure 4. Figure 4 Feedback loop showing the regulation of ovarian hormones by gonadotropic hormones. (a) Identify as W‚ X‚ Y‚ or Z the two gonadotropic hormones

Protocol for Lab 5 – Aerobic Respiration Part 1 Isolation of Mitochondria from Cauliflower - Weigh 50g of rosettes cut from fresh cauliflower head. - Cut rosettes and place it on ice - Prepare juice extractor by placing ice and an empty 150 ml beaker into the right compartment. - Collect pulp from left compartment and record total volume of the extract. Approx. 20ml - Filter the pulp using six layered cheese cloth and collect it in a beaker sitting on ice. - Place two 50 ml test tubes

1. By exhaling out carbon dioxide into the straw on top of the bromothymol blue indicator‚ the solution will turn the color blue into a yellowish-green color. When there is a presence of something that is acidic the BTB indicator changes its color into yellow/green. So in this case‚ the water with BTB and carbon dioxide exhaled into the flask creates a carbonic acid. As an aerobic activity increase than the carbon dioxide rate increases as well. 2. By exercising more‚ one’s body requires more
