<span>The answer would be: C)Play loud music at precisely 2:30 in the afternoon for two weeks.
All other option is involving an action at 10.30 AM </span>which the only times 'The Magic Donkey' is aired on the television. If Roger wants to prove the hypothesis, he should do the experiment when <span> 'The Magic Donkey' is aired, not before or after it.</span>
Answer:
The correct answer is: upper esophageal sphincter.
Explanation:
The alimentary canal is a very long tract responsible for the digestion of the food. It is composed of several organs with many different and important functions. The alimentary canal also has a few sphincters, which are muscular valves that open and close when needed for the food to pass or be retained.
The first sphincter is the upper esophageal sphincter. One particularity of this sphincter is that is one of the few sphincters in the body that opens and closes under our conscious control, which happens when we decide to swallow our food.
From the first to the last, the order of the sphincters in the gastrointestinal tract is: upper esophageal sphincter, lower esophageal sphincter or gastroesophageal sphincter, pyloric sphincter, ileocecal sphincter, and anus.
The conduction of nerve impulses relies upon the movement of positively-charged ions across the nerve cell membrane. The entry of sodium into the cell produces a wave of positive charge that travels down the length of an axon. Then chemicals called neurotransmitters are secreted out of the end of the axon onto the next nerve in the series (the postsynpatic nerve). This narrow space in between neurons is called the synapse. These neurotransmiiters released by the presynaptic nerve bind to receptors on the postsynaptic nerve. The binding of these receptors opens up channels in this second nerve's membrane that allow sodium ions to enter the nerve cell and initiate another wave of positive charge, and so on... The nerve signal can only move as fast as these ions and neurotransmitters can diffuse to generate this process.
<span>As a professional athlete repeats a given activity many times over, the nerve cells "upregulate" their receptors, meaning that they produce additional receptors to put in the membrane. This is just a natural reaction to the nerve being repeatedly stimulated in the same way over and over. When neurotransmitter is secreted from the presynaptic neuron, there are more receptors on the postsynaptic neuron for it to bind, more channels open up, more ions enter in a shorter time and build up positive charge to create the impulse faster, and so the overall effect is faster. </span>
<span>Additionally, there are sheaths of fatty tissue (called myelin) that insulate the charge in the neuron and allow it to be conducted faster. As people age, these sheaths can start to degrade, making the nerve cell more "leaky" and causing the impulse to be conducted more slowly. </span>
<span>OCT1 is a protein that hepatic which serves as a uptake transporter which is on the blood side of hepatocytes whose primary function is disposition of cationic drugs. OCT1 recognize the position on the DNA molecule by recognizing the specific sequence of bases as it has the binding motif.</span>
Answer:
The correct options are B "The unusual F1 female is heterozygous for a reciprocal balanced translocation involving the chromosome with the apricot, bristle and clipped loci" and D "Independent assortment of non-compatible chromosome structures (i.e., translocated and normal chromosomes segregating together) in the F1 female led to the 90 eggs that aborted development"
Explanation:
The unexpected results obtained earlier can be attributed to the two factors listed above. At the time when meisois takes place, there is the process of independent assortment which leads to formation of zygotes. Due to the event of translocation, the eggs produced lacked some critical development genes.
