Which feedback stimulates your body to respond in the same direction as a stimulus positive or negative?
1
Minimum level of stimulation required to trigger a neural impulse?
An action potential needs to occur to trigger the neurons but the action potential depends on whether a stimulus is able to bring the membrane potential to a certain level termed the THRESHOLD. This threshold is about -55 mV for most neurons, but the stimulus needs to bring the membrane potential to this certain level or it will not be triggered. Relating to the ALL-OR-NONE PRINCIPLE, which if the threshold is not acquired then an action potential will not occur but once a stimulus is strong enough to depolarize (making the inside of the cell less negative going from -70 mV to -55 mV) it will trigger. The resting potential is -70 mV which the stimulus needs to bring it up to -55mV.
Difference between nastic movement tropic movement?
Nastic response occur in a part of a plant that grows towards a non-directional stimulus while Tropic response occur in a part of a plant that grows towards or away from a directional stimulus.
Where do electron transport occur?
in the inner membrane of the mitochondia
Can diffusion occur through a nonliving membrane?
Yes, it can.
Feedback stimulates your body to respond in the same direction as a stimulus?
Positive feedback loops rarely occur. This is because positive feedback stimulates your body to respond in the same direction as the stimulus, most often increasing instability

What events occur in a neuron between the stimulus of a nerve and the stimulation of its target cell?
When a nerve is stimulated, its cell membrane is depolarised so that the inside of the cell becomes less negative. The potential is conducted along the axon to the axon terminal. At the dendrite it stimulates the release of a chemical transmitter, which diffuses across a synapse. The transmitter binds to receptor sites on the postsynaptic cell membrane to stimulate the generation of another impulse.
What must be paired together for classical conditioning to occur?
For classical conditioning to occur a neutral stimulus must be paired with an unconditioned stimulus. The neutral stimulus is initially meaningless to the organism but becomes associated with the unconditioned stimulus after the two are repeatedly paired together. This process of association is known as classical conditioning. The following are the components needed for classical conditioning to occur: A neutral stimulus An unconditioned stimulus A response ReinforcementThe neutral stimulus is something that does not initially produce a response. It is usually a sound taste or smell. The unconditioned stimulus is something that naturally produces a response. It is usually a food or something that causes pain or discomfort. The response is the reaction to the unconditioned stimulus such as salivating or flinching. Reinforcement is the use of rewards or punishments to strengthen the association between the neutral stimulus and the unconditioned stimulus.
When is operant stimulus control achieved?
Operant stimulus control is achieved when a behavior consistently occurs in the presence of a specific stimulus due to its history of reinforcement or punishment. This means that the behavior is more likely to occur when that stimulus is present and less likely in its absence.
Where does the eletron transport chain occur?
Inner membrane of the mitochondria and thylakoid membrane of chloroplasts.
Reproduction would not occur if which part of a cell was removed?
The Cell Membrane
Where does ETS occur?
Inner Mitochondrial Membrane
Where do the light dependent occur?
On the thylakoid membrane :)
What is the occurrence of a learned response to stimuli that are similar to the original stimulus is called stimulus?
Generalization. It refers to the tendency for a learned response to a specific stimulus to occur in the presence of other stimuli that are similar to the original stimulus.
Can osmosis occur in the absence of menbrane?
Osmosis is a type of diffusion that occurs with a semi permeable membrane. It can therefore not occur without a membrane because that is what differentiates it from diffusion.
