“Cell Transport Lab” Hypothesis: I hypothesis that there will be a movement of molecules out of the egg‚ and will move into the water solution. Osmosis will occur within the egg‚ and in the process the molecules of the egg will diffuse. Time (hrs) | Observations | Circumference (cm) | * 0 | * Egg is of normal weight and size * No membrane is being shown‚ and is almost perfect | * 14 centimeters | * 24 | * Egg has gotten larger taking in some of the water * Shell is soft

An Experiment of Adaptation Introduction: Throughout history of time‚ organisms change in relation to their environment‚ consequently‚ adaptation is an essential property of life. This experiment is designed to test the adaptation of Drosophila melanogaster. This kind of insect is also called fruit flies‚ it has been widely used in scientific research because it has a short life cycle about two weeks and it is easy to keep large numbers of them (Manning). Two groups of this species will be used

Module 1 Physics: The Basic Science What this module is about The study of science has two branches namely‚ the life sciences and the physical sciences. The life sciences include biology‚ zoology and botany. The physical sciences branch into areas such as geology‚ astronomy‚ chemistry and physics. However‚ physics is more than part of physical sciences because it does not only deal with matter and energy but it also deals with the other basic concepts like motion‚ forces‚ heat‚ sound‚ light

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

Lab Four: Skeletal Tissues This week‚ we are examining tissues of the skeletal system. Specifically‚ we will investigate the process by which the long bone of the upper arm‚ the humerus‚ grows and lengthens in our patient‚ an 8-year old boy. Then‚ we will compare this process of growth with the process of healing and repair when this same patient sustains a distal end greenstick fracture of the humerus at his weekly gymnastics practice! Your assignment‚ which is worth 30 points‚ is to write
