An impulse moves from one neuron to another across a small space called synapse.
<span>
A nerve impulse is transmitted via electrical stimulus (within the cell) and chemical signal (between cells). Two neurons (or neuron with effector cell) communicate one to another by <span>a structure called synapse. Synapse is actually a little space between the end of the axon and dendrite of another cell (but without material continuity between both cells). The axon releases chemical molecules called neurotransmitters, which then attach to receptors in the membrane of the following cell.</span></span>
The intermediate disturbance hypothesis predicts that species diversity will be highest when the frequency and/or intensity of disturbances are intermediate
Explanation:
The diversity of the species is maximised at an intermediate near of anthropogenic as well as natural disturbances. As the competitively inferior disturbances are being tolerated for species disturbance and are termed to be dominant. Co exist of the sensitive species when the disturbance are either frequent or rare, which possess the reduced level of the disturbances. the productivity is predicted as very less due to competitive exclusion. As the disturbances increases productivity becomes less as most of them unable to sustain the regular destructive occurrence. So with the intermediate disturbances productivity is high as the rapid colonizers and dominant competitors are able to coexist.
<span>The epidermis is a layer of skin which contains the most bacteria in the skin. Upper parts of hair follicles also have those microorganisms a lot. Skin microbiota is usually non-pathogenic and has a defensive role (for example, preventing pathogenic organisms to enter the skin surface). Even though, bacteria can cause skin diseases (for example, acne) and enter the blood system.</span>
