What else can I help you with?
What is a protective response to a stimulus?
Metaplasia (refferig to a cell)
What is the different between an external stimulus and an internal stimulus?
The difference between an external stimulus and an internal stimulus is that an external stimulus is a stimulus that comes from outside an organism. But an internal stumulus is a stimulus that comes from inside an organism. An example for an external stimulus can be that when you are cold, you put on a jacket. An example for an internal stimulus is that when you feel hungry, you eat food.
In positive feedback the initial stimulus produces a response that the stimulus?
exagerrates the stimulus
What is a change in an organism's surrounding that causes the organism to react?
The answer to this would mose probabaly be a stimulus. Because there are 2 types of stimuli Internal Stimulus and External Stimulus and so it has to be either one of these but the answer is stimulus.
Is the sudden drop in air temperature a stimulus or response?
The sudden drop in air temperature is a stimulus.
What is the internal stimulus for a cell to divide?
claustrophobia
What is a protective response to a stimulus?
Metaplasia (refferig to a cell)
If a muscle cell receives a second stimulus while it is contracting will it respond to the second stimulus?
no because it doesnt want to
What period is it when a cell is unable to accept another stimulus?
refactory period
What is the relationship between a stimulus and a response?
A response is always triggered by a stimulus. One example is in a neuron (nerve cell). Once a sensory stimulus is witnessed (a stimulus from one of the 5 senses), the cell hits an action potential, and the response is carried out. Simply put: A human eye is closed. Once the eye opens thousands of sensors in the eye pick up the photons bouncing off all objects (stimulus), and the human is able to see (response).
Movement of a cell toward a chemical stimulus is termed?
positive chemotaxis
What happens when a stimulus activates a receptor?
The activation of a second messenger inside the receiving cell, the triggering of enzyme activity in the cell, and the change of permeability of the cell.
What is the difference between the effective refractory period and the relative refractory period?
-The effective refractory period is the time in which the cell is incapable of responding to a second stimulus between the phases of 0-3.5, while the relative refractory period is the time in which the cell is making preparations to receive stimulus between phase 3.5-4.
Given that action potentials traveling down the axon of a particular neuron are always the same amplitude how is a stronger stimulus communicated to the next cell in the neural pathway?
A stronger stimulus is communicated to the next cell in the neural pathway by increasing the frequency of action potentials generated by the neuron. A stronger stimulus will trigger action potentials to occur more frequently, which results in a higher frequency of signals being transmitted to the next cell.
Immediately following the arrival of the stimulus at a skeletal muscle cell there is a short period called?
The short period following the arrival of a stimulus at a skeletal muscle cell is called the latent period. During this time, the muscle cell is preparing for contraction by releasing calcium ions and activating the contractile proteins.
The cell that initiate the stimulus for contraction of the heart muscles are located in the?
The SA Node in the right atrium
What is the transmission of the stimulus at the neuromuscular junctions involves?
The transmission of the stimulus at the neuromuscular junction involves the release of acetylcholine from the motor neuron, binding to acetylcholine receptors on the muscle cell membrane, causing depolarization of the muscle cell, and ultimately leading to muscle contraction.
