Answer:
"Those who doubt the effectiveness of this treatment for pain attribute the pain relief to a placebo effect: if a patient believes something will reduce their pain, they will experience some relief."
Explanation:
There is no scientific evidence to prove the healing effect of acumpulture, so some people do not believe it to be a reliable method when relieving pain. The above shows why people who do not believe in the healing power of acupulture believe that those who undergo this treatment really feel a relief from pain. People who do not believe in acupuncture relate this relief to the placebo effect.
Placebo is any substance without pharmacological properties, administered to persons or groups of persons as if it had therapeutic properties. The placebo effect happens when people believe so much that a (ineffective) treatment will work that it actually works.

Evidence for evolution how are dna and comparative anatomy used to show relatedness
Answer:
Homologies and vestigial structures are two evidences of the evolution of how DNA and comparative anatomy used to show relatedness
Explanation:
Living organisms have characteristics that make them similar to others, which may suggest that at some point in the history of life on Earth, they shared a common ancestor. When we look at the limbs of a crocodile and a rat, for example, we find that, despite their differences in morphology, they are quite similar in anatomy, suggesting that they may be related. In this case, we say that the characteristic is homologous, that is, it has a similar embryonic origin, but it does not always perform the same function.
Trace structures are structures that are atrophied and have no apparent function in an organism. The presence of these organs can be interpreted as evidence of evolution, since the structure, today without much apparent function, may in the past have been extremely important to the ancestors of that species.
Evidence for evolution are Fossil Record, Homologous Structures, DNA and Molecular Evidence. DNA and Comparative Anatomy to Show Relatedness as DNA Sequencing, Molecular Clock.
1. Fossil Record: The fossil record provides evidence of how species have changed over time. Fossils of extinct organisms help to establish transitional forms, showing the gradual changes and relatedness between different species.
2. Homologous Structures: Homologous structures are anatomical features in different species that share a common ancestry but may have different functions. These similarities suggest a common evolutionary origin. Comparative anatomy studies these structures and their patterns of variation across species.
3. DNA and Molecular Evidence: DNA and molecular analysis have revolutionized our understanding of evolution. By comparing the DNA sequences of different species, scientists can determine their degree of relatedness. Similarities in DNA sequences provide evidence of common ancestry and evolutionary relationships.
2) DNA and Comparative Anatomy to Show Relatedness:
1. DNA Sequencing: DNA sequencing allows scientists to compare the genetic material of different species. The more similar the DNA sequences are between two species, the more closely related they are thought to be. For example, humans and chimpanzees have a high degree of DNA sequence similarity, indicating a close evolutionary relationship.
2. Molecular Clock: Molecular clock analysis uses DNA mutations to estimate the time when two species diverged from a common ancestor. By comparing the number of genetic differences between species and the mutation rate, scientists can approximate the time of divergence and infer relatedness.
3. Homologous Genes: Just as there are homologous structures, there are also homologous genes. These are genes that are shared between different species because they were inherited from a common ancestor. The study of homologous genes provides strong evidence of shared evolutionary history.
4. Comparative Anatomy: Comparative anatomy examines the similarities and differences in the anatomical structures of different species. Homologous structures, such as the bones in the limbs of vertebrates, reveal common ancestry and relatedness.
5. Embryonic Development: Comparing the embryonic development of different species can reveal similarities in early stages, providing evidence of shared ancestry. For instance, the early embryos of fish, reptiles, birds, and mammals share common features, suggesting a common evolutionary origin.

Two chickens are bred and have five offspring, shown below. What are the most likely genotypes of the parents?
Without the specific offspring genotypes, the most likely genotypes of the parents are inferred to be heterozygous (Bb) based on Mendelian inheritance patterns.
Explanation:The question given pertains to the inheritance patterns and predicting offspring genotypes using Mendelian genetics principles. The scenario hints that the parental generation is likely composed of heterozygous individuals because the offspring exhibit a variety of genotypes typically resulting from a heterozygous cross. To answer this with high accuracy, one would need the precise phenotypes or genotypes of the offspring. Assuming a Mendelian trait with simple dominance and using the provided information, if offspring show a typical 3:1 phenotypic ratio, or a 1:2:1 genotypic ratio with the presence of dominant and recessive traits, we can infer the most likely genotypes of the parents to be heterozygous (Bb).
The most likely genotypes of the parents are Bb and bb.
Explanation:In Mendelian genetics, feather color in chickens is determined by a single gene with two alleles: B (black feathers) and b (white feathers). The capital letter represents the dominant allele, and the lowercase letter represents the recessive allele. Black feathers (B) are dominant over white feathers (b). Looking at the offspring, we can deduce the genotypes of the parents.
Since the first, third, and fifth offspring have black feathers, the only way that can happen is if the parent contributing those alleles has at least one dominant B allele. The second and fourth offspring have white feathers, which means they inherited a recessive b allele from both parents. Therefore, the genotype of the first parent is likely Bb, and the second parent is bb.
This conclusion is supported by the fact that the black-feathered offspring can inherit either a B allele or a b allele from the Bb parent, resulting in black feathers. Meanwhile, the white-feathered offspring must inherit a b allele from each parent (bb) to express the recessive trait. Thus, the most likely genotypes of the parents are Bb and bb, which is consistent with the observed phenotypes of the offspring.
Complete question: Two chickens are bred and have five offspring, shown below. What are the most likely genotypes of the parents?
Offspring:
1. Black Feathers (B_)
2. White Feathers(bb)
3. Black Feathers(B_)
4. White Feathers (bb)
5. Black Feathers (B_)

If one gram of each of the following were eaten as food, identify which would yield the most energy within the cell.
Answer & explanation:
When we refer to macronutrients, we talk about proteins, carbohydrates and lipids.
In a meal, carbohydrates are usually in greater quantity than proteins and fats, and are primarily used as fuel for metabolic processes.
Carbohydrates have on average 4 kcal per gram (or 17 kJ/g), proteins also have 4 kcal/g, but fats are approximately 9 kcal per gram (or 37 kJ/g).
Thus, fats have a higher energy charge compared to proteins and carbohydrates, although they are not primarily used as cellular fuel.

Down's syndrome is caused by trisomy of chromosome 21, where individuals inherit an extra copy of the chromosome instead of the normal two. there is a wide range in the severity of the disease experienced by each individual, but experience lifelong intellectual disabilities and a number of associated health problems. one of the most common problems experienced by those with down's syndrome, is the early onset of alzheimer's disease (usually emerging between the ages of 30-45), with up to 75% developing dementia in their lifetime (ness et al., 2012). one of the reasons behind this is the fact that the gene encoding for amyloid precursor protein (app) is present on chromosome 21. due to this, individuals with down's syndrome produce more app.
a. what is app and why would this genetic change make alzheimer's disease much more likely to develop?
Amyloid precursor protein (APP) is an integral membrane protein expressed in many tissues and concentrated in the synapses of neurons with unknown function. APP is the precursor molecule whose proteolysis generates beta-amyloid (Aβ), a whose amyloid fibrillar form is the primary component of amyloid plaques. Amyloid plaques are found in the brains of Alzheimer's disease patients. APP gene is triplicated in patients with Down’s syndrome. As a result, an amyloid deposition which is associated with Alzheimer's disease is present in all Down syndrome patients older than 30.

The diversity found among dna molecules is due to the sequence of _______.
Final answer:
The diversity among DNA molecules comes from the sequence of nucleotides, which can create a vast number of combinations despite having only four types. Mutations contribute to this diversity by altering DNA sequences, leading to variations among individuals.
Explanation:
The diversity found among DNA molecules is due to the sequence of nucleotides. Even though DNA consists of only four different bases — adenine (A), cytosine (C), guanine (G), and thymine (T) — the arrangement of these nucleotides can vary infinitely. Each organism has a unique DNA sequence, which serves as a genetic blueprint vital for its development, functioning, and reproduction. This genetic diversity is the foundation of the wide variety of life on Earth.
Mutations are changes in the nucleotide sequence that can occur spontaneously or due to external factors like radiation or chemicals. These mutations can lead to variations among individuals within the same species, contributing to the biological diversity we observe. Such variations include single nucleotide polymorphisms (SNPs), which are differences in single nucleotides between individuals, further highlighting the role of nucleotide sequences in genetic diversity.

Out of the following given choices;
A)the offspring will have traits of both parents.
B)there is genetic variation among the offspring.
C)all the offspring will be genetically identical.
D)none of the offspring will be genetically like the parents.
The answer is C. This is because, in binary fusion, they are no formation of gametes. Therefore genetic variability that comes with sexual reproduction not found in asexual reproduction. Mostly, the offspring buds off from the parent or grows from a split part of the parent. Therefore the offspring is genetically identical to the parent
