question one: For O2 in the atmosphere to be inhaled there must be a contraction of 2 sets of respiratory muscles. The diaphragm forms the bottom of the thoracic cavity and the external intercostals muscles which are located between the ribs. The contraction of the diaphragm causes an increase in the vertical dimension of the thorax. The contraction of the external intercostals muscles cause an increase in anterio-posterior and transverse diameter of the thorax. Together this causes a decrease in

these factors can lead to imbalances in other areas as well (Wise‚ 2010). The importance of this lab is to analyze factors that may affect urine concentration‚ pH‚ and rate of production (flow rate) though multiple scenarios over a period of 60 minutes. My hypothesis for the urine analysis experiment is that the urine volumes will increase because of the increase of fluids to the body for groups 1 and 3‚ in comparison with the control group (group 4)‚ and decrease in the group not group 2 based

| Stage 2 Biology | | Adelaide High School | [Osmosis Practical Report] Abstract: | The purpose of this investigation is to see if the concentration of Sodium chloride (NaCl) solution will affect the mass of the potato cylinder hence the rate of osmosis. This can be done by placing 5‚ identical in length (3cm) but different in weight‚ tubes of potato in 5 different beakers. Each containing an altered NaCl concentration. The concentrations used in this experiment were‚ 0%‚ 2%‚

Osmosis Lab Report The essential focus of the experiment was to acquire data for the mass change resulting from osmosis in order to determine the carbohydrate solution of the carrot cells. The carrots were a vegetable used within the experiment with a carbohydrate solution around .5 M. The hypothesis is if there are carrots in different carbohydrate solutions then there will be a percent change in mass. The carrots have large vacuoles that hold water‚ this allows the mass to increase when the hypertonic
