Answer:
She is not moving.
Explanation:
It is stated that Pierre is observing both of them the same way which means that they are both moving in the same direction at the same speed, 4m/s. According to the relative speed concept, they will observe each other according to the difference in their movement directions and speed. Since they are moving in the same direction and at the same speed, Gabriella will be observed as if not moving from Michellle's point of view.
I hope this answer helps.
Answer:
B) generator potential
Explanation:
The short-lived and localized changes in membrane potential are called graded potentials. A sensory receptor senses the stimulus. As the stimulus is sensed by the associated sensory neuron, there is the production of a graded potential. When the receptor of a sensory neuron is excited by some form of energy such as heat, light, etc., the resulting graded potential is called a generator potential. It is also called a receptor potential.
If the receptor potential is large enough to reach the threshold, it triggers one or more nerve impulses in the axon of the sensory neuron. For instance, thermosensory receptors sense the change in the temperature conditions and the associated sensory neurons generate the graded potential. Since the graded potential is generated due to temperature (heat), it is a generator potential.
The unusual property that cytochromes have in common with hemoglobin or myoglobin is that all of them contain heme groups. Cytochromes are heme-containing electron transport enzymes which are essential for the oxidative metabolism necessary to generate adenosine triphosphateas well as for the oxidative degradation of drugs and endogenous substrates.
