Artavious noticed that his music sales were declining. Other companies were doing well by boosting
advertising, so he thought maybe he should as well. He wanted to find out which type of advertising would
boost sales the most, and to make sure that was the factor that made the difference. So he continued using
just word of mouth advertising for his original songs and tracked their sales, changing nothing. He used tiktok
advertising for his new releases and radio advertising for his remixes and tracked their sales. All songs had
the same artist, musicians, and genre.

Thomas Malthus' most well known work An Essay on the Principle of Population was published in 1798. His thesis on the human condition was radically opposed to current thinking at the time. He argued that increases in population would eventually diminish the ability of the world to feed itself and he based this conclusion on the idea that populations expand in such a way as to overtake the development of sufficient land for crops. We can apply Malthus' thesis as analogous to the concept of population carrying capacity. Malthus' ideas regarding population can be applied to natural selection. Identify a critical component of both Malthus and natural selection that is reflected in the graph from "overshoot" to "die off".A)Genetic drift may occur and randomly select certain individuals to survive and reproduce.B)Overpopulation occurs but cannot be supported; not all members of a population get to reproduce.C)In any population where variation exists, sexual reproduction occurs among the most successful members.D)In any large population, genetic variation exists due to the presence of mutations. Some are advantageous, other are not.
Answers
We have to consider that in those points of the graphs, "overshoot", and "die-off", there's a behavior in each population that Malthus stated in his work, and which is also related to natural selection: organisms begin to reproduce themselves benefiting on the favorable conditions, such as the food and land resources, among others, such as the partner availability, and when they reach the carrying capacity, their population overreaches a limit that can no more sustain all the individuals. Considering this, we can say that the answer that better relates to a critical component of both Malthus and natural selection reflected on those points of the graph is the second one, which states "overpopulation occurs but cannot be supported; not all members of a population get to reproduce".
What helps make different types of carbohydrates?
Answers
Answer:
glycosidic bonds between monosaccharides that combine to form polysaccharides
Explanation:
The building blocks of carbohydrates are individual monosaccharides (i.e., sugar molecules), such as glucose, fructose, glucuronic acid, galactosamine, glucosamine, etc. These individual monomers of carbohydrates bond to form polysaccharides such as cellulose and starches. Monosaccharides form glycosidic bonds with an alcoholic OH group of a second monosaccharide to form a disaccharide (for example, lactose), and then these larger molecules bond together to form either linear or branched polysaccharides. Starch, for example, is a polysaccharide composed of monomers of glucose molecules.
Identify when mutations that involve DNA coding to Amino Acids occur when
Answers
Mutations that involve DNA coding to amino acids occur during the process of transcription and translation.
What is mutation?A mutation is a permanent change in the DNA sequence that makes up a gene. Mutations can occur spontaneously, or they can be caused by exposure to certain environmental factors, such as radiation or chemical mutagens. Mutations can be beneficial, harmful, or have no effect on the organism, depending on the nature and location of the change in the DNA sequence.
Mutations can result in the creation of new traits or the loss of existing traits, and they play an important role in evolution. Some mutations can lead to genetic disorders or diseases, while others can have no effect on the organism. Mutations can also be passed down from generation to generation, making them an important factor in the inheritance of traits and the evolution of species.

Answers
The two pieces of evidence that support the theory of the expanding universe are the red shift of light from distant stars and the existence of cosmic background radiation.
The correct answer is option B.
1. Red shift of light from distant stars: The observation of redshift in the light coming from distant galaxies provides evidence for the expansion of the universe. Redshift occurs when the light waves from an object moving away from an observer are stretched, causing a shift towards longer wavelengths. This phenomenon is consistent with the Doppler effect, where the wavelength of light appears to stretch as the source moves away. The redshift of light from distant stars indicates that galaxies are moving away from us and from each other, supporting the idea that the universe is expanding.
2. Existence of cosmic background radiation: The discovery of cosmic background radiation further supports the theory of the expanding universe. Cosmic background radiation is a faint, uniform microwave radiation that permeates the entire universe. It is believed to be residual radiation from the Big Bang, the initial event that is thought to have initiated the expansion of the universe. The presence of cosmic background radiation provides strong evidence for the hot, dense early stages of the universe and its subsequent expansion.

You are studying a disorder that is based on the genetic composition at three loci. Assume that a dominant allele at any locus adds 5 units of risk for the disorder and that a recessive allele at any locus adds 3 units of risk for the disorder. Individuals with 26 or more units of risk develop the disorder. The environment does not affect the presence or absence of this disorder. How many risk units will be present in an individual of genotype AABbcc
Answers
Answer:
24
Explanation:
Given that:
At either locus, the expression of the dominant allele increases the risk by 5 units.
The assigned genetic sequence "AABbcc" has three dominant alleles, implying that it increases risk by 15 units.
At any locus, the expression of the recessive allele increases the risk by three units. The assigned genetic sequence "AABbcc" has three recessive alleles, which means it increases the chance by 9 units.
In an individual with the genotype AABbcc, the total number of risk units is = 15+9 = 24. This implies that the person does not develop the disease).

In Activity 2, which of the respirometers serves as a control? Explain your answer! Why was it the control? You should write at least 3 sentences to explain this. Respirometer A contains germinated beans. respirometer B contains dormant beans and plastic beads respirometer C contains plastic beads.
Answers
In Activity 2, the respirometer C serves as the control. A control is an essential part of any scientific experiment as it provides a baseline against which the experimental results can be compared.
Respirometer C containing only plastic beads does not contain any living organisms and therefore does not undergo cellular respiration. By comparing the results of respirometers A and B with the control (respirometer C), any changes in oxygen consumption and carbon dioxide production can be attributed to the metabolic activity of the germinated beans in respirometer A and the dormant beans in respirometer B.
This allows researchers to determine the specific effects of germination on cellular respiration by isolating the variables and eliminating any external factors that could influence the results.

Explain what the acoustic measure H1-A3 is. Additionally discuss why a large value of the measure H1-A3 would reflect a breathy voice. (Hint: consider using these terms: vocal fold closure, spectral tilt).
Answers
The acoustic measure H1-A3 represents the difference in frequency between the first harmonic (H1) and the third formant (A3) in a speech signal.
The first harmonic is the lowest frequency component of the voice signal, while the third formant is a resonance frequency that is related to the shape and size of the vocal tract.
A large value of H1-A3 indicates that the third formant is higher in frequency than the first harmonic, which is a characteristic of breathy voice quality.
This is because breathy phonation is associated with incomplete vocal fold closure, which results in a weaker and more turbulent airflow through the vocal tract.
This causes a change in the spectral tilt, which in turn leads to an increase in the frequency of the third formant relative to the first harmonic, resulting in a larger H1-A3 value.

Which statement best distinguishes an observation from an inference?
An inference is likely to change based on additional observations.
An observation is likely to change based on additional inferences.
An observation involves assumptions, but an inference does not.
An inference involves the senses, but an observation does not.
Answers
The correct answer is A. An inference is likely to change based on additional observations.
Explanation:
In science, an inference is made when you use the information from observations, previous studies, among others to get to a conclusion. This process often involves making assumptions based on what you know, because of this, inferences can change if evidence disproves it. For example, you might infer all plants have the same growth rate if you studied two or more plants of the same species and the growth rate was the same, but this can be disproved if you study plants of other species.
On the other hand, an observation is a statement you made based on evidence, this includes observing a phenomenon or measuring it with a precise instrument. This means, observations are not based on assumptions and therefore are precise and often fixed. Thus, one key difference between observations and inferences is "An inference is likely to change based on additional observations."
