Answer:
TRUE
Explanation:
Phasic receptors are sensory receptors that are fast acting in detecting changes in the strength of a particular stimulus or signal to the brain. They are fast adapting receptor cells that detect changes in the strength of a stimulus. Because of this fast adapting ability, they cannot be used by the CNS in constant signalling of stimulus. A different receptor called Tonic receptors are used by the brain for constant signalling because they are slow reacting cells are they continue to transmit signals to the CNS along as the stimulus remains and not to changes in the pressure or strength of the stimulus. Phasic receptors are so important in predicting the changes in the body fora given time and this helps to quantify how body can react to increase or release of a stimulus. because when stimulus is added it signals the brain for some time and it signals stops but when the stimulus is released, it also signals the brain detecting bodily deformations to various stimulus.
Answer:
Why does the amount or dose entering the body matter? ... A point would be reached where beneficial effects would disappear and harmful effects would start to be noticed. ... harmful is directly related to the amount of it taken into the body at one time. ... Chemicals with high toxicity only need small doses to cause poisoning.
Explanation:
<span>there are several differences, here are some:
kingdoms: sunflower = plant; amoeba = ProtistaCell
membranes: sunflower = cell wall; amoeba = semipermeable membrane only
organelles: sunflower = cholorplasts; amoeba = pseudopod
</span><span>Cell organization: sunflower = differentiated multicellular: amoeba = single cell
<span>Habitat: sunflower = confined to land areas; amoeba = confined to water
