1.a. Increase pressure from the thoracic cavity onto the venae cavae causes the stroke volume to decreases‚ cardiac output would decrease‚ venous blood pressure would eventually increase and venous return would also eventually increase. b. Fainting is due to a drop in blood flow to the brain. And holding your breath causes the heart rate to slow and blood vessels to dilate‚ which then leads to blood pools in the lower body and less blood going up to the brain. c. Compensatory mechanism that become

Document 1 What did Hitler suggest was needed for Germany? Hitler thought Germany needed to take back the territories that were lost as part of the reparations of WWI. He thought the land was still theirs and they should take it back. How would that lead to war? Hitler wanted to take the lost territories by force‚ so that would easily lead to war. He said protests weren’t enough and they needed to fight which was implied by “a mighty sword” being necessary. Document 2 According to Haile Selassie

which cell has the larger resting membrane potential? Explain. If the permeability to K is higher in A than in B‚ then the resting membrane potential (rmp) will be closer to the equilibrium potential in cell A‚ which means the rmp will be more negative in cell A than in cell B; or in other words‚ the potential difference will be LARGER in cell A. 2. Predict the effect of a reduced extracellular concentration of Na+ on the magnitude of the action potential in an electrically excitable cell. If there

desiccation. Slaters prefer lower light intensities‚ this helps them keep hidden from predators and cool; not exposed to heat and not lose too much water‚ as they would do in greater light intensities Slaters show orthokinesis‚ as light intensity increases and decreases from their preferred intensity. This means they are less likely to spend a lot of time in unfavourable conditions Slaters show negative phototaxis so they move out of bright light. Brighter light conditions are usually drier‚ so by staying

Finger Response Times to Visual‚ Auditory and Tactile Modality Stimuli By Christopher Watts 9MLO Introduction: The time it takes from when an individual responds to a certain stimulus that they have detected is commonly referred to as reaction time. This delay in time is caused by the amount of time it takes information to go through the nervous system and then towards your brain. Your brain acts as the processor of your body and translates these informative signals so that your body can act

Changes in the volume of milk yield according to milking interval are summarized in Table 1. Accumulated milk volume in the camel mammary glands increased with time elapsed after the last milking for the 4-h to 24-h milking intervals studied (Fig. 1). Both linear and logarithmic models satisfactorily fit the observed values; the prediction equations are being (y is milk volume in liters and x is milking interval in hours; P0.05) in milk total protein (3.44±0.19)‚ milk lactose (4.01±0.19) and ash
