area of LOW to High solute concentration. 3. Because water moves toward the HIGH concentration of solutes. 4. We know the pressure will increase in the albumin beaker because it is more impermeable than glucose. The pressure in the beaker containing the albumin increased despite the increased concentration of glucose because albumin has a much greater molecular weight. Activity 4 1. Increasing the size of an opening allows more space for movement. For example‚ the more you open the nozzle

Biology exam Endocrine system: Hormones: chemical messengers that coordinate the body’s activates. Substances secreted by cells that act to regulate the activity of other cells in the body. They are part of the endocrine system and they are slow acting but have a longer affect than neurotransmitters. Functions: * regulate growth‚ development‚ behavior‚ and reproduction. * Maintain homeostasis * Regulate metabolism and water and mineral balance * Respond to external stimuli

Activity FOUR There is a direct relationship between the MWCO and the filtration rate; the higher the MWCO‚ the higher the filtration rate. Powdered charcoal is the solute that did not appear in the filtrate when using any MWCO membranes. As pressure increases‚ the filtration rate also increases‚ as long as the MWCO does not decrease. Since we have no control over the MWCO of a living membrane‚ we can increase the rate of filtration by increasing the pressure. The molecular weight

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

The Relationship Between The Nervous System and The Endocrine System The cells and tissues in the body are delicate and easily disrupted. They will only be able to function well if all aspects of their chemical and physical environment is continuously adjusted to keep them stable and in equilibrium. The process in which several body systems work together to maintain the balanced environment is called homeostasis. The endocrine and nervous system work closely together to help maintain homeostasis
