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%.

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.

The author did something in this work that I never thought was possible. She made death enjoyable to read about. She even stated‚ “Death. It doesn’t have to be boring.” (Roach 11).

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

A khap panchayat in Haryana ‘declares’ that mobilization of women(of a particular age gap) should be monitored(in reality restricted). Marriage by choice or outside one’s caste or inside one’s gotra is forbidden and those who challenge it‚ become a story in themselves.
