Lab 3 – Homework 1. Purpose of today’s experiment: To determine the effect osmotic pressure might have on cellular membranes‚ specifically when beet slices are placed in NaCl solutions of varying concentrations. 2. Hypothesis: The osmolarity will directly increase with increasing NaCl concentrations. 3. Control = Distilled Water – this was present in all solutions 4. The independent variable – salinity of the 6 solutions; while predetermined‚ the NaCl concentrations varied from 0% to 15%.

Arthropod (crayfish) Dissection Megan Williamson period: 3 4/29/13 Objectives: The purpose of this lab was to study and observe the organs in a crayfish and be able to name them. Introduction: Crayfish belong to the kingdom animilia‚ phylum arthropod and class crustaceans. The body is divided into three parts‚ the body‚ the head‚ thorax‚ and abdomen. The head and thorax are apart of a segment called cephalothoraxes‚ which is covered by the carapace made of chitin

relatively uncommon. The condition most frequently occurs in men in their 60s and 70s. An aortic dissection is a serious condition in which the inner layer of the aorta‚ the large blood vessel branching off the heart‚ tears. Blood surges through the tear‚ causing the inner and middle layers of the aorta to separate (dissect). If the blood-filled channel ruptures through the outside aortic wall‚ aortic dissection is often fatal. The other condition known as tamponade is a clinical syndrome caused by the

The methods can be the cold steel dissection where the tonsils are removed as a whole using sharp metal instruments and the bleeding is controlled with ties or sutures (Hazarika & Nayak‚ 2005). Methods by using monopolar or bipolar diathermy where the tonsils are dissected using the diathermy. Tonsillectomy can also be done by using the laser and finally the most commonly used now in most hospital is the coblation method. Coblation is a radio-frequency dissection method that cuts the tissue by breaking

predicted to reduce muscle cell contraction. G proteins in the signal transduction pathway of acetylcholine prevented adenylyl cyclase and the opening of potassium channels which was supposed to reduce cardiac muscle contraction. The light of the dissection microscope may have inhibited this reduction. Every time the light was turned on‚ its intensity accelerated the heart rate of the D. magna. The D. magna was unable to cope with this light change because it was constantly turned on and off during
