Lab Exercise 2: Acceleration A. Objective This experiment will provide data to calculate the acceleration of a marble as it rolls down an incline plane over measured periods of time. To do this‚ the marble’s velocity will be determined and then its acceleration. 1. What is the distance between two marks in your inclined plan? -50cm 2. What is the angle of your inclined plan with respect the horizontal? -16degrees 3. Newton’s first law says a body at rest will remain at rest unless

Summarise the main development of a child from the age range 0-2 years‚ 3-5 years and 5-8 years Although the development of each child is unique to the individual‚ there are certain ‘milestones’ that need to be achieved before a child moves on to the next stage of its development. These milestones‚ or averages‚ are used to assess the development of an individual child‚ all the time recognizing that different children will reach these milestones at different times. There are five defined areas

Animal-pollinated plants have fragrant or showy flowers to attract the animals. Fungi‚ such as mold‚ Baker’s yeast‚ and mushrooms produce almost no spores. When environmental conditions are harsh‚ some bacteria form thick-walled‚ resistant spores‚ called ectospores The hard outer layer‚ or shell‚ of a pollen grain or

REVIEW SHEET EXERCISE 12 Serological Testing NAME: LAB TIME/DATE: Positive and Negative Controls 1. Why are there a number of washing steps in serological tests? They are needed in order to remove any non specific binding that may happen. 2. Describe how you would know that you had a “false positive” result. What does this mean for the rest of your results? If it has a negative control then it’s a false positive so the results are invalidated. 3. Describe how you would

PHYSIOEX 9‚ ACTIVITY #3 Review Questions ACTIVITY #1 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out the neuron through the K+ leak channels? 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare with your predictions? 3. Explain why a change in extracellular Na+ did not significantly alter the membrane potential in the resting neuron? 4. Discuss the relative permeability

Explain why the larger waves seen on the oscilloscope represent ventricular contraction. The ventricular contraction is when the blood is sent through the whole body as opposed to the atrial contraction that sends the blood to the heart and lungs. 2) Explain why the amplitude of the wave did not change when you increased the frequency of the stimulation. (Hint: relate your response to the refractory period of the cardiac action potential) How well did the results compare with your prediction? The

Define each of the following terms: • motor unit - A motor unit consists of a motor neuron and all of the muscle fibers it innervates. • twitch - Skeletal Muscle twitch is the mechanical response to a single action potential. It has three phases known as the latent‚ contraction‚ and relaxation phase. • threshold - the threshold is the minimal stimulus needed to cause a depolarization of the muscle plasma membrane
