CARDIOVASCULAR SYSTEM The Cardiovascular system consists of the cardio -heart and the vessels that carry blood to all parts of the body. If this system does not work properly then oxygen‚ hormones‚ water‚ nutrients and wastes won’t reach their target destinations. 5 liters of blood in body.

experiment we compared the hemagglutination reaction of control Con A solution at 2 mg/ml in Con A buffer with the hemagglutination reaction of your own purified Con A sample that you diluted previously at 2 mg/ml in Con A buffer. The purpose of this lab was to determine the strength of the reaction by performing serial dilutions on both the Con A sample and the control Con A sample‚ and determine through observations whether or not addition of galactose or mannose will inhibit this reaction. I hypothesize

begin the lab‚ he/she must make a prediction about what gene the trait one are analyzing is on. The trait can either be sex-linked‚ or autosomal. To begin the lab‚ one must acquire a sample of flies to cross. These flies should be placed in a tube with an easily removable foam stopper. Use the flynap to knock out the fruit flies‚ and pour them out of the tube into a petri dish. Then place the petri dish on a stereomicroscope‚ and begin using a paintbrush to sort the flies by gender. Male flies have sex

Effect of Enzyme and Substrate Concentration on Reaction Rate by Zachary A. Poché Biology 155 Laboratory October 15‚ 2014 Lab Partners: Cade White‚ Hannah Ragas‚ Russheka Aremillion ABSTRACT In order to increase the reaction rate‚ substrates attach to the active site of enzymes which decrease the activation energy required to convert substrates to products. We examined the effect of enzyme concentration and substrate concentration on the overall rate of the reaction. To determine

LAB #2 QUESTIONS PART A: ENDOCRINE GLANDS OF THE HUMAN 1. Complete the following chart: Please see the attached chart for the Endocrine System. 2. Explain the mechanism of communication‚ control‚ and integration in the endocrine system. The Endocrine systems mechanism of communication is sending messages from the cells of the endocrine and nervous system to the cells in other systems by releasing hormones. The Endocrine systems control feature is part of negative feedback because it

melanogaster is a common fruit fly that has been useful for most experiments in the study of Genetics. The male and the female fruit fly are similar and different in regards to how they look‚ structurally. They are similar because both genders have a head‚ thorax‚ proboscis‚ antennae‚ eyes‚ and mouth parts. However‚ males are smaller than females and have about five abdominal segments as opposed to the seven that the female has. The life cycle of these fruit flies consist of egg‚ larvae‚ metamorphosis

melanogaster commonly known as the fruit fly is considered a model organism in the field of genetics because of its short life cycle of about 10 weeks and the ability of the fly to produce a relatively large number of offspring at 50-70 eggs per day upon female maturity. The physical size of the male and female Drosophila is approximately 2.5 to 3 mm respectively Drosophila allowing for minimal storage space in a laboratory setting. The intricate nervous system of the fruit fly has made them very vital to genetic

In my BIO 102 lab I have learned about the Microscope and Lab Safety‚ Sensory Organs (Eyes and Ears)‚ The Human Blood and Circulation‚ and Respiration. Once I first started this class this semester taught us about the Microscope and Lab Safety. According to google online dictionary a Microscope is an optical instrument used for viewing very small objects‚ such as mineral samples or animal or plant cells typically magnified several hundred times. We used this instrument to look at different types

Laura Lugo Group: Bianca Jonson Short lab report 10/4/14 Effect of household drugs on circulatory system of Lumbriculus Variegatus (blackworms) Hypothesis & justification part 1: In order to understand a little bit about the effects of common household drugs such as nicotine and caffeine on pulsation rate‚ an experiment was conducted with Lumbriculus Variegattus (Blackworms). In week 1‚ we observed the basal rate of three different worms‚ and then placed the same three worms on different concentrations
