Explanation:

The Whale Shark (Rhincodon typus) and the Humpback Whale (Rhincodon megaptera) both have the same first part of their scientific names.

By binomial nomenclature, proposed by Carl Linneaus, we know that a scientific name consists of two parts :

Genus and species

Hence, we can say they both belong to the same genus.

The controversy between protein and DNA as the genetic material was resolved when experiments demonstrated that DNA, not protein, carries the hereditary information.

There was a significant scientific controversy surrounding the nature of genetic material in the early days of molecular biology. While proteins were initially considered strong candidates for carrying genetic information, it was ultimately discovered that DNA (deoxyribonucleic acid) is the molecule responsible for storing and transmitting genetic information. However, the connection between proteins and DNA, known as the "missing link," was initially overlooked.

The main reason proteins were initially favored as the genetic material was that they exhibited a remarkable structural diversity, and it was known that proteins played crucial roles in various cellular functions. Additionally, proteins were composed of 20 different amino acids, providing a greater potential for complexity and variation compared to the four nucleotides found in DNA.

One key experiment that played a significant role in the controversy was performed by Frederick Griffith in 1928. Griffith was studying the bacterium Streptococcus pneumoniae and observed that a non-virulent strain could become virulent when exposed to a heat-killed virulent strain. This phenomenon was termed "transformation." However, at the time, the precise nature of the transforming substance was unknown.

The turning point came in 1952 with the work of Alfred Hershey and Martha Chase. They performed an elegant experiment using a virus called bacteriophage T2, which infects bacteria. They tagged the protein coat of the virus with radioactive sulfur and the DNA with radioactive phosphorus. By infecting bacteria and separating the virus from the bacteria, they demonstrated that only the radioactive DNA, not the protein coat, was transferred to the bacterial cells. This experiment provided direct evidence that DNA, not protein, was the hereditary material.

The connection that was initially missed between proteins and DNA was the role of DNA as the template for protein synthesis. In 1953, James Watson and Francis Crick proposed the double-helix structure of DNA, and crucially, they suggested that the sequence of nucleotides in DNA could encode the sequence of amino acids in proteins. This proposal laid the foundation for the understanding of the genetic code, where specific sequences of DNA nucleotides (codons) correspond to specific amino acids, forming the basis for protein synthesis.

Once the connection between DNA and protein synthesis was established, it became clear that DNA's ability to store and transmit genetic information, its chemical stability, and its ability to undergo mutations were all properties essential for a molecule serving as the genetic material.

In summary, the controversy between protein and DNA as the genetic material was resolved when experiments demonstrated that DNA, not protein, carries the hereditary information. The missing link was the understanding of DNA's role as a template for protein synthesis, which provided the connection between the two molecules and confirmed the central role of DNA in storing and transmitting genetic information.

The statistical support for a phylogeny is often indicated by a metric called the "bootstrap value," which represents the percentage of times that a particular branch or clade appears in a set of resampled datasets.

The higher the bootstrap value, the more strongly supported that branch or clade is by the data. For example, a bootstrap value of 70% indicates that the branch or clade was present in 70% of the resampled datasets, suggesting that it is a reliable and robust feature of the phylogeny.

Other metrics, such as Bayesian posterior probabilities and maximum likelihood support values, can also be used to assess the strength of support for different branches or clades in a phylogenetic tree.

The molecule that acts on brain centers to decrease appetite in mammals and other vertebrates is called leptin.

Leptin is a molecule that acts on brain centers to decrease appetite in mammals and other vertebrates. It is produced by adipose tissue and regulates energy balance by inhibiting hunger signals and stimulating energy expenditure. When the body's fat stores increase, leptin levels increase, which signals the hypothalamus to decrease appetite and increase metabolism. This feedback loop helps maintain a stable body weight by balancing energy intake and expenditure.

Leptin acts on specific receptors in the hypothalamus, particularly in the arcuate nucleus, to regulate appetite and metabolism. It also influences the release of other hormones involved in regulating energy balance, such as ghrelin, which stimulates appetite, and insulin, which regulates glucose metabolism.

As the skateboarder moves, several energy transformations take place within their body. Some of the energy transformations include:

1. Chemical energy to kinetic energy: When the skateboarder pushes off the ground, the energy stored in the chemical bonds of their muscles is converted into kinetic energy, which is responsible for their motion.

2. Kinetic energy to gravitational potential energy: As the skateboarder moves up a ramp, their kinetic energy is converted into gravitational potential energy.

3. Gravitational potential energy to kinetic energy: When the skateboarder moves down the ramp, the gravitational potential energy is converted back into kinetic energy.

4. Kinetic energy to thermal energy: As the skateboarder moves, they also experience frictional forces which convert some of their kinetic energy into thermal energy.

5. Chemical energy to thermal energy: The continuous movement of the skateboarder requires the energy stored in their muscles to be converted into thermal energy, which is released as heat.

I hope that the assistance I provided was helpful.

The motion of the skateboarder is powered by energy transformations that occur within their body. As the skateboarder moves, their body converts stored chemical energy (from food) into kinetic energy, which is the energy of motion. This conversion happens through a series of complex biochemical processes that occur within the skateboarder's muscles.

When the skateboarder pushes off the ground, their leg muscles contract, converting chemical energy stored in the form of ATP (adenosine triphosphate) into kinetic energy as the legs move and the skateboarder accelerates. As the skateboarder continues to move, the muscles in their body work together to maintain balance and control, converting chemical energy into kinetic energy and potential energy as the skateboarder jumps, turns, and performs tricks.

Additionally, the skateboarder's body also experiences other forms of energy transformation during this process. For example, as the skateboarder moves, their body generates heat through metabolic processes, which is a form of thermal energy. The skateboarder also loses energy through friction with the ground and air resistance, which is converted into heat and sound energy.

In summary, the motion of the skateboarder is powered by a series of complex energy transformations that occur within their body. These transformations involve the conversion of stored chemical energy into kinetic and potential energy, as well as the generation of heat and sound energy through friction and air resistance.

According to the textbook, "white fragility" refers to more than 100 and a variety of defensive moves that White people make when challenged racially. It is a term coined by Robin DiAngelo to describe the defensive behaviors of White people when their beliefs about race are challenged.

According to DiAngelo, white fragility is a state in which even a minimum amount of racial stress becomes intolerable, triggering a defensive response from white people that includes defensiveness, argumentation, and emotional distress. White fragility causes white people to feel anxious and angry, leading to defensive responses that protect them from the uncomfortable feelings of guilt, shame, and denial that come with acknowledging and addressing racism.

According to DiAngelo, white fragility is a symptom of white supremacy because it reinforces the racial hierarchy by making it difficult for white people to confront and dismantle racism. By recognizing and challenging white fragility, white people can work toward becoming more effective allies in the struggle for racial justice.

d) Translation.

Small regulatory RNAs (sRNAs) are non-coding RNAs that play a critical role in regulating gene expression in prokaryotic and eukaryotic cells. Some types of sRNAs are known to inhibit translation by binding to the mRNA and preventing ribosomes from initiating translation. This process is known as post-transcriptional gene silencing (PTGS).

PTGS is a highly conserved process that is used by cells to control gene expression and to prevent the accumulation of misfolded proteins. By inhibiting translation, sRNAs can prevent the synthesis of proteins that are not needed by the cell or that could be harmful. In prokaryotes, sRNAs have been shown to regulate a wide variety of cellular processes, including stress response, virulence, and quorum sensing.

Although sRNAs are primarily known for their role in inhibiting translation, they can also regulate other cellular processes, such as replication, mutation, and recombination. For example, some sRNAs have been shown to inhibit the replication of viruses by binding to the viral RNA and preventing replication. Similarly, sRNAs have been shown to inhibit the recombination of DNA by binding to the DNA and preventing the formation of recombination intermediates.

Following a heavy meal, the small intestine absorbs glucose into the blood, and the rise is detected by the pancreas, which releases insulin. The liver absorbs glucose as a result of the action of this hormone, and the blood glucose level falls.

Insulin aids the body in glucose regulation. The correct paragraph is as below. "Shortly after a heavy meal, glucose is absorbed from the small intestine, and its concentration in the blood cells goes up. This rise is detected by the pancreas, which releases the hormone insulin into the blood. Insulin makes the liver take the extra glucose from the blood and store it as glycogen. Later on, the concentration of glucose in the blood drops. The liver breaks down glycogen so that it goes up again. After a while, the majority of glucose from the meal is stored as glycogen in the liver, resulting in less free glucose in the blood as the level drops".
