_ play at least some role in regulating breathing - cns, motor pathways, somatic nervous system, autonomic nervous system a key aspect of cooperative binding by hemoglobin is that - it permits rapid uptake of oxygen in the lungs and greater delivery of oxygen once blood reaches capillaries in the body's tissues A shark's blood contains low concentration of ions but relatively high concentration of urea. This increases their blood osmolarity so that it is nearly osmotic with seawater. Base...

Biology 2 Exam 9-TBD Questions & Answers 2024/2025 osmoconformers - ANSWERSmarine organisms that maintain an internal environment that is osmotic to their external environment. This means that the osmotic pressure, or osmolarity, of the organism's cells is equal to the osmotic pressure of their surrounding environment. osmoregulators - ANSWERStightly regulate their body osmolarity, maintaining constant internal conditions. osmotic challenges faced by animals in freshwater environment...

osmoconformers isosmotic with their environment, marine invertebrates osmoregulators adjust internal osmolarity, marine vertebrates, freshwater fish, terrestrial animals freshwater fish problems gain water by osmosis, lose electrolytes by diffusion freshwater fish hypertonic to environment freshwater fish solutions don't drink water, lots of urine, add electrolytes by diet and active transport marine fish hypotonic to ocean

osmoregulation - Answer Regulation of solute concentrations and water balance by a cell or organism. especially vital to control the influx or withdrawal of water in hypertonic or hypotonic solutions osmoregulators - Answer more common in the animal kingdom strictly regulate their internal environments and keep water levels constant within their cells don't change their salt or water levels according to their surroundings, but maintain constant levels ACTIVE process MUST regulate...

Agonist - Competitive inhibition, binds to active site and causes a signal response in receptive tissue. Antagonist (blocker) - Competitive inhibitor, binds to active site so signal molecules cannot bind but causes no response in receptive tissue, can bind and release eventually. Apply your understanding of channels and synapses to predict how various neurotoxins affect nervous function. - Neurotoxins block receptor proteins on the post-synaptic neuron. Example: tetrodotoxin form Fugu fish...
