The best way to compare the nervous system and the endocrine system is to compare the characteristics of speed, specificity and plasticity (abilityto respond and change permanently, particularly with respect to strength and speed.) The nervous system uses rapid electrical signals along nerve axons.Chemical signals are used between nerve cells at synapses. Although this chemical transmission is slower than electrical transmission, synapses are important in transmission between nerve cells. The endocrine system uses hormones, which are secreted into and transported to their target cells via the <span>circulation of blood. Due to the delay of circulation, hormonal responses.</span>
Neural transmission: 1) is transmitted by neurones. 2) quick response 3) involves neurones 4) short lived 5) may be voluntary or involuntary 6) usually localised
Endocrine signal transmission: 1) transmitted by blood 2) usually slow responses 3) involves hormones 4) may be short lived or long lived 5) involuntary 6) may affect more than one target organ
tympanic cavity .. The primary function of the tympanic cavity is to offset the decrease in acoustic energy that would occur if the low impedance ear canal air directly contacted the high-impedance cochlear fluid.
The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.
The correct answer is B: Time-consuming process of listing endangered species. It is an example of a failed attempt to reintroduce clapper rails in California. The California clapper rail is noted as an endangered species. Endangered species are plants and animals that are in close danger of being extinct.
