The structure located on top of Darron's brainstem that caused him to lose his sense of taste is called the nucleus of the solitary tract (NTS).
The NTS is part of the autonomic nervous system and is responsible for relaying taste information from the tongue to the brain. The NTS is also involved in the control of breathing, blood pressure, and other bodily functions. In Darron’s case, a tumor in the vicinity of the NTS caused damage to the nerve cells in the area, resulting in a disruption of the signals that travel from the tongue to the brain. This has led to a complete loss of his sense of taste.
Although the tumor is the cause of Darron’s loss of taste, it is the damage to the NTS that is responsible for the symptom. The NTS is located in the medulla oblongata, which is a major part of the brainstem and is responsible for controlling many of the body’s involuntary functions.
The NTS is a cluster of neurons that receive taste information from the tongue, and then relay it to the brain. When the cells of the NTS are damaged, the signals that travel from the tongue to the brain are disrupted, resulting in a complete loss of taste.

5. Describe the metabolic pathways in the monarch butterfly that take advantage of milkweed nectar to convert it into an energy currency.
A) Include details about the three phases of cellular respiration as they relate to sugar metabolism.
B) Where (or how) would sucrose enter the pathways?
Milkweed nectar is rich in a sugar, which is called sucrose. This sugar is a disaccharide, made of glucose and fructose. Sugar is broken down into glucose and fructose in the body, using an enzyme called invertase.
The three phases of cellular respiration are as:
Glycolysis is the process by which glucose is converted into energy. In glycolysis, two ATP molecules are made per glucose molecule. Two NADH molecules are also made. Aerobic organisms, such as monarch butterflies, can further process sugars. In the mitochondria, one CO₂ molecule is removed from the sugar, and one NADH is produced.The Kreb cycle is a series of eight enzymatic reactions that produce energy in the form of ATP. In the Kreb cycle, acetyl-CoA is completely oxidized to produce carbon dioxide. This process is aided by the production of NADH, FADH₂, and a molecule of GTP. Oxaloacetate is regenerated to continue the cycle.Oxidative phosphorylation is the process that generates a proton gradient across the inner mitochondrial membrane. This gradient is used by the V ETC complex to generate energy. The V ETC complex is located in the inner mitochondrial membrane, and as protons flow back and forth through the complex, it catalyzes the phosphorylation of ADP to produce ATP.Learn more about cellular respiration https://brainly.com/question/14158795

The lac Operon is considered an inducible operon. Explain what this means making reference to and comparing the trip operon
The lac operon is an inducible operon, meaning that it is expressed only when needed. This is in contrast to a repressible operon, such as the trp operon, which is turned off in response to a stimulus.
The lac operon is activated when lactose, its inducer, is present in the environment. This activates the lac repressor, which in turn binds to the DNA, blocking the transcription of the genes. When the inducer is absent, the repressor is not activated, so the genes are expressed. In contrast, the trp operon is activated when the repressor is absent.
When the repressor is present, the trp operon is not expressed, and when the repressor is absent, the trp operon is expressed. Therefore, the lac operon is activated when its inducer is present, while the trp operon is activated when its repressor is absent.

The most common example of mutations are: Color blindness, Cystic fibrosis, Down syndrome.
Mutations are the change in the normal genetic sequence of the DNA that results in varied gene expression. Mutations can be at a single nucleotide or they can be over large strand of DNA, called point mutations and frameshift mutations respectively.

"Comrades!" cried Squealer, making little nervous skips, "a most terrible thing has been discovered. Snowball has sold himself to Frederick of Pinchfield Farm, who is even now plotting to attack us and take our farm away from us! Snowball is to act as his guide when the attack begins. But there is worse than that. We had thought that Snowball's rebellion was caused simply by his vanity and ambition. But we were wrong, comrades. Do you know what the real reason was? Snowball was in league with Jones from the very start! He was Jones's secret agent all the time. It has all been proved by documents which he left behind him and which we have only just discovered. To my mind this explains a great deal, comrades. Did we not see for ourselves how he attempted—fortunately without success—to get us defeated and destroyed at the Battle of the Cowshed?"
The animals were stupefied. This was a wickedness far outdoing Snowball's destruction of the windmill. But it was some minutes before they could fully take it in. They all remembered or thought they remembered, how they had seen Snowball charging ahead of them at the Battle of the Cowshed, how he had rallied and encouraged them at every turn, and how he had not paused for an instant even when the pellets from Jones's gun had wounded his back. At first, it was a little difficult to see how this fitted in with his being on Jones's side. Even Boxer, who seldom asked questions, was puzzled. He lay down, tucked his forehoofs beneath him, shut his eyes, and with a hard effort managed to formulate his thoughts.
"I do not believe that," he said. "Snowball fought bravely at the Battle of the Cowshed. I saw him myself. Did we not give him 'Animal Hero, First Class,' immediately afterwards?"
"That was our mistake, comrade. For we know now—it is all written down in the secret documents that we have found—that in reality, he was trying to lure us to our doom."

which amino acid will be added next during protein
synthesis. Each sequence of three nucleotides is called
A. a protein
B. a codon
C. a Mutagen
D. a DNA molecule
Answer:
DNA molecule
Explanation:
Each sequence of three nucleotides is called a codon. Therefore, the correct answer is option B.
Codons are named by the request for their bases. The three stop codons in mRNA are UAA, UAG, and UGA, where U represents uracil, A for adenine, and G for guanine. Stop codons signal the end of protein synthesis. They can be found in DNA or mRNA.
They are three-nucleotide sequences that encode a particular amino acid. During the translation process, the tRNA (transfer RNA) molecules contain anticodons that aid in the transfer of amino acids to the mRNA.
A codon is a sequence of three nucleotides in DNA or RNA, also known as a trinucleotide. It is a unit of genomic information that encodes a specific amino acid or signals the end of protein synthesis (stop signals).

What would happen if a mistake were not caught by the proofreading mechanism and became permanent in the DNA
If a mistake were not caught by the proofreading mechanism and became permanently incorporated into the DNA, the consequences could be catastrophic.
The DNA is the blueprint for all life, and any mutation or alteration can cause a range of problems, from minor to severe. If the mistake were to alter a gene that is important for cell survival, it could lead to a range of health problems, from mild to life-threatening.
For example, if a gene that is responsible for the production of a certain enzyme is altered, it can cause a metabolic disorder, leading to physical and mental disabilities. If the mistake were to alter a gene that is responsible for the functioning of a specific organ, such as the heart or brain, it could lead to serious health problems, such as heart defects or neurological disorders.
If the mistake were to alter a gene responsible for the development of an organism, it could lead to serious developmental defects or even death. For example, if a gene that provides instructions for the development of the body's organs is altered, it could lead to serious malformations or even death.
In addition to the health risks, a mistake in the DNA could also lead to changes in the species. For example, if a mutation alters a gene that is important for the survival of a species, it could lead to the extinction of the species. This could be due to a decrease in fertility, a decrease in the population size, or an inability to adapt to a changing environment.
