Sometimes the effects of sympathetic stimulation can be contradictory in the same types of tissue. For example, in the arterioles of the GI tract, sympathetic stimulation causes constriction while arterioles of skeletal muscle can dilate in response to sympathetic stimulation. What mechanism explains these opposite effects?

Neurotransmitter & Receptors

Explanation:

A neurotransmitter can typically tie to and initiate various diverse receptor proteins. Regardless of whether the impact of a specific neurotransmitter is excitatory or inhibitory at a given neurotransmitter relies upon which of its receptor(s) are available on the postsynaptic (target) cell In spite of the fact that the normally happening neurotransmitter ties to the entirety of its relating receptor types, the diverse structure of these receptors implies that a few medications tie more promptly to one kind of receptor than another. This is perfect for accomplishing one explicit medication activity while limiting reactions. And, it is useful for widening the aviation routes in the treatment of asthma, while having a lot more vulnerable impact on the heart, thus limiting undesirable impacts, for example, tachycardia (expanded pulse).Hence,the correct answer is "different receptors for the same neurotransmitter".

Processes above and be sure to mention the movement of electrons and energy as the carbon atom moves from one reaction to another.

The answer would be c, white eyes are homozygous recessive. in the early 1900s, morgan conducted several experiments with vinegar  flies (drosophila). one  sample revealed an anomaly: a  white-eyed, single male fly. he attempted to breed this fly with the typical red-eyed females. the offspring were all red-eyed. using flies from this new generation (brother-sister pairs)  produced some red-eyed and a few white-eyed flies. the white-eyed were all male. in later experiments, he was able to produce white-eyed females. this proved that white eyes are not lethal to either sex (ruling out a and b). since the percentage of white eyes to red eyes is so low, white eyes are not a dominant trait. it would be a recessive trait.
