Prior to injecting the neurotoxin‚ Tubocurare‚ inside the gastrocnemius muscle‚ a control was established. The baseline was maintained approximately at 20 grams. The control used the maximum voltage of 0.75 volts for the stimulus input. As a result‚ the tension produced 68.13 grams of force. The moment Tubocurare was infused into the gastrocnemius muscle‚ the muscle tension dropped to 47.7 grams of force. Data was recorded for 10 minutes‚ and as predicted prior to the experiment‚ the tension trend

1/ What is the driving force in the diffusion? Randomness. As far as forces go i believe you can end up with a pressure if you have two different concentration on opposite sides of a membrane. Cells have been know to explode as a result of this effect. Wikipedia.org‚ "The World’s Encyclopedia" really says it best Search ’Molecular diffusion" "Molecular diffusion‚ often called simply diffusion‚ is a net transport of molecules from a region of higher concentration to one of lower concentration by

living are dropping further behind the richest countries. The gap in incomes between the 20% of the richest and the poorest countries has grown from 30 to 1 in 1960 to 82 to 1 in 1995. 3. Increased trade and travel have facilitated the spread of human‚ animal and plant diseases‚ like HIV/AIDS‚ SARS and bird flu‚ across borders. The AIDS crisis has reduced life expectancy in some parts of Africa to less than 33 years and delays in addressing the problems‚ caused by economic pressures‚ have exacerbated

What are the functions of the skeleton? The five functions of the skeleton are: protecting the vital body organs‚ giving shape to the body and providing support to body organs and holding the body upright. Others are facilitating movement and producing of blood. The latter function is done in the bone marrow. 2. What is the difference

BIOLOGY ASSIGNMENT 3 TASK 1 HOMEOSTASIS Homeostasis can be defined as a point of balance or internal equilibrium that all kind of system both living and non-living can work to keep themselves in this state of balance. Mechanisms of homeostasis in human body Temperature Regulation: If your body too hot or cold‚ there are several ways in which your temperature can be controlled. They involve sweating‚ shivering‚ capillaries and hairs. As we learn in the class when your body becomes; Too hot When

Reyes November 08‚ 2011 Dr. Dunaway Neuronal signaling in muscle contraction is triggered when an action potential reaches the neuromuscular junction. At this junction‚ acetylcholine (ACh) is the main neurotransmitter. Packaged in vesicles‚ ACh fuses with the neuron’s membrane and is released into the synaptic cleft. ACh diffuses toward the motor end plate and bind to the neurotransmitter receptor on it. The muscle fiber is then triggered to produce an action potential of its own that

Muscular System: Muscle Metabolism 1. List the three roles of ATP in muscle contraction: 1. _Energize the power stroke of the myosin cross bridge. 2. _Disconnecting the myosin head from the binding site on actin at the conclusion of a power stroke. 3. _Energizing the calcium ion pump. 2. The potential energy in ATP is released when the terminal high-energy bond is broken by a process called hydrolysis. Write the end products of this process: ATP (+ H2O) (
