Answer:
The correct answer is option A. "the temporary hyperpolarization of the axon membrane following the action potential spike".
Explanation:
Action potentials, also known as "spikes" or "impulses", are electric impulses that neurons use to send information from the cell's body down to the axon. The impulses are created when ions travel across the neuron's membrane creating a depolarization current. This depolarization current is responsible for an temporary hyperpolarization of the axon membrane following the action potential spike. When neurons are hyperpolarized they are not able to produce another action potential. In consequence, actions potentials move in one direction along the neuron away from the cell body, as well as, adjacent locations go trough similar depolarization processes.
Answer:
sensation and paresthesia
Explanation:
Sensation and paresthesia are the terms that would indicate a patient is suffering from neuropathic pain. Sensation is concrete, conscious experience resulting from stimulation of a specific sense organ or sensory nerve, or in the brain of an individual. Paresthesia is a type of abnormal sensation of the skin (tingling, chilling and burning etc) without any apparent physical cause in the body.
Answer:
The influenza H1N1 virus is transmitted through saliva droplets and mucus from sick people, who by sneezing or coughing without covering their mouth and nose adequately, leave the virus in the air or on their hands, infecting then the objects they touch. As a rare occurrence, a person can become infected with the flu by touching a surface or object contaminated with the influenza virus and then touching the mouth, nose, or eyes.
Pigs sometimes transmit influenza H1N1 virus to people, primarily pig farmers and veterinarians.
Answer: D: Measure the amount of energy in the phytoplankton and the amount of light entering the aquarium. Then measure the amount of energy in the phytoplankton after exposure to the light and determine the difference.
Explanation: This will describe the law as the amount of energy leaving the system will be the same as measured before exposure to light.
If a given moth population is at Hardy-Weinberg Equilibrium, we can conclude that the changes in the allele frequency of the population over time is constant. This means that in the absence of evolutionary influences, allele or genotype frequencies remain constant from one generation to the next or so on.
