- Explain the pressure-flow hypothesis and the cohesion-tension theoryIf a fish close to the surface swam down to a depth of 10m below the surface it would need to ______ to maintain neutral buoyancy. let air out of its swim bladder to keep the volume constant let air out of its swim bladder to reduce the volume constant put air into its swim bladder to keep the volume constant put enough air into its swim bladder to double the volumeHelp on number 2 Do not understand what needs to occur at 25mmhg and 50 mmhg with a pressure/volume graph and laplace law
- State whether the following factors would tend to increase or decrease the amount of dissolved oxygen in water or neither. Lowering the temperature [ Choose ] Pesticides [ Choose ] Phosphate containing chemicals [ Choose ] Organic waste [ Choose ] Plastics [ Choose ] Waterfalls [ Choose ] F10 >blood ph varies between 7.35 and 7.45, with a target value of 7.4. if someone's blood ph begins to decrease, chemoreceptors detect this change and send the information to the brain the brain analyzes the input and sends out a command to the respiratory muscles causing breathing rate to increases, which reduces carbon dioxide levels and thereby increases the ph of ther blood. name the body part, values, or actions in this specific scenario involving ph Normal range Set point Stimulus Sensor integrsting center Effector ResponseCompare the effects of hypothermia and hyperthermia onthe circulation
- Gas exchange is more difficult for aquatic animals with gills than for terrestrial animals with lungs because CHECK ALL THAT WOULD APPLY water contains much more O2 per unit volume than air gills allow water to flow in one direction. water contains much less O2 per unit volume than air gills have less surface area than lungs. water is denser than airExplain how & why the dissolved oxygen concentration changes with depth. Be sure to include the OMZ.Using the data below, draw 4 pie charts for water gain and water loss in a kangaroo rat and a human.
