what is the role of myelin in neurons? a) to change the direction that Na+ and K+ move through ion channels during the action potential b) to increase the speed that action potentials travel down the neuron c) to prevent the neuron from generating action potentials d) to cause multiple sclerosis when present and intact, […]
Discuss the phylum Platyhelminthes. Refer to the presence or absence of a coelom, symmetry type, basics of nervous system, and type of digestive tract in the free-living forms.
Discuss the phylum Cnidaria. What are the basic body forms? Also, state the type of symmetry present and if these organisms have tissues and organs (and if present, state the number of tissues and organs).
Explain the evolutionary biology of infectious disease. Driven by a constant arms race between microbial pathogens and their hosts, pathogens evolve mechanisms to evade host defense, develop drug resistance, adapt to the host environment
Please provide an explanation of what is a biogeochemical cycle and describe the main features of the two (2) main biogeochemical cycles, which provides fertilizer nutrients. This nutrient supply is being negatively alfected by the Russia/Ukraine war (12 marks). c.
Define decomposition and briefly describe any three factors that affect the rate of decomposition. Please provide an explanation of what is a biogeochemical cycle and describe the main features of the two (2) main biogeochemical cycles, which provides fertilizer nutrients. This nutrient supply is being negatively alfected by the Russia/Ukraine war (12 marks). c.
Describe the significance and importance of nutrient cycling to the physico-chemical processes of the organisms found in tropical ecosystems
A possible benefit of lateralization is improvement in divided attention abilities. faster communication between the two hemispheres. “backup” in the event of brain damage. increased diversity among a population.
Classical conditioning in Aplysia results primarily from the release of larger amounts of neurotransmitter by the sensory neuron. the release of smaller amounts of neurotransmitter by the sensory neuron. increased sensitivity of the motor neuron. larger numbers of active interneurons.
What is the primary function of Myelin sheath? to supply nutrients to axon to carry waste from the axon to increase the speed at which nerve impulse travel to conduct active transport of potassium ions What makes it possible for an impulse to move from one neuron to an adjacent neuron The axon of one […]
