homeostasis - correct answer-the tendency of an organism to maintain a stable internal environment, though the external environment changes reflex control - correct answer-long distance control of homeostasis, using either neural or hormonal signals local control - correct answer-control of homeostasis at a cellular level, isolated changes in a few cells or a tissue (i.e. environment of the cell, fluid level, etc) input, controller, output - correct answer-3 major components of homeosta...

Glucocorticoids correct answers enhance actions of glucagon and catecholamines (epinephrine) by promoting glycogenolysis and gluconeogenesis during stress Physiology correct answers the study of how organisms work (eg. form and function) 1st law of thermodynamics correct answers energy cannot be created or destroyed 2nd law of thermodynamics correct answers entropy (disorder) always increases Input/output budget correct answers energy must be budgeted and allocated towards various bo...

What is a pathogen? ~~> A microorganism that causes disease e.g. bacteria, fungi, virus, parasite For an effective immune response the immune system must... ~~> - be able to recognise and respond to any invading organism - not over react to benign or self - be able to direct different effector mechanisms against different pathogens What is specific/adaptive immunity? ~~> - it is induced by exposure to a particular infection - shows a high degree of specificity - exhib...

What is the purpose of the scientific method? The scientific method is an organized way to study the natural world and find out how it works. What are the steps of the scientific method? Ask a Question. Do Background Research. Construct a Hypothesis. Test Your Hypothesis by Doing an Experiment. Analyze Your Data and Draw a Conclusion. Communicate Your Results. Distinguish between independent and dependent variables An independent variable is the variable that is changed or ...
