Three human disorders−−fragile X syndrome, myotonic dystrophy, and Huntington's disease−−are conceptually linked by a common mode of molecular upset. Choose the phenomenon that links these disorders. Three human disordersfragile X syndrome, myotonic dystrophy, and Huntington's diseaseare conceptually linked by a common mode of molecular upset. Choose the phenomenon that links these disorders. All three are caused by disparate genes, but each gene was found to contain repeats of the same trinucleotide sequence. All three are X-linked, but each gene was found to contain repeats of the same trinucleotide sequence. All three are caused by disparate genes, but each gene was found to contain repeats of a unique trinucleotide sequence. All three are X-linked, but each gene was found to contain repeats of a unique trinucleotide sequence.
Answer:
The correct answer is ''All three are caused by disparate genes, but each gene was found to contain repeats of a unique trinucleotide sequence.''
Explanation:
Four groups of trinucleotide repeats related to DNA expansion have been characterized in the human genome. CGGI GCC, CAGIGTC, CTGIGAC and recently GW CTT sequences. The CGGl GCC sequences are usually located in the noncoding regions of different genes and when expanded they associate with fragile sites on the chromosomes. The CAGIGTC repeats are part of the coding region and are related to different neurodegenerative disorders. You can try to make a classification depending on the unit that is repeated, having on one side a group that are caused by repeats of the CAG trinucleotide (cytosine, adenine, guanine). Huntington's disease (HD) is a progressive disorder of motor, cognitive and psychic function. The disease is inherited in an autosomal dominant manner, and is caused by the expansion of CAG trinucleotide repeats in exon 1 of the gene called huntingtin (HTT or IT-15). Unstable mutations have also been found in which the repeat unit does not is composed of three nucleotides, if not four, such as type 2 myotonic dystrophy, where the tetranucleotide CCTG repeats. Fragile X Syndrome consists of an abnormal expansion of the cytosine-guanine-guanine trinucleotide (CGG) in the FMR1 gene, which prevents intellectual disability and also influences the formation of connective tissue

Match each graph with its correlation coefficient.
+1.0
+0.85
+0.15
-0.50
-1.0
Answer:
-0.50
Explanation:
For the graph displayed, the most probable value of the correlation Coefficient is - 0.50 ; the line of best fit has a negative skoe and hence will have a negative relationship as the correlation Coefficient is a statistical value which measures the degree of relationship between two variables. Also, the distribution of data in the plot does not give a perfect fit, hence a correlation Coefficient of - 1.0 isn't possible for the distribution shown.

A cladogram is shown below. What is a derived characteristic that distinguishes the salamander from the perch? lungs claws or nails fur jaws
About the question:
You will a cladogram in the attached files.
Answer:
lungs
Explanation:
A Cladogram is a tree-type graph based on cladistic analysis. It represents the common ancestral relationships among the involved groups.
• The tree-type graph is a ramified diagram that represents the relationship between the involved taxa.
• The cladistic analysis follows the maximum parsimony criterium. Explains the character state from the point of view of the fewest changes through history. Explains evolution with the minimal amount of evolutive changes. It recognizes the monophyletic groups as natural groups. These groups are the clades, and their classification -sequencing- represents their phylogeny.
• The sequencing term refers to lists of groups according to their relation. One group is the brother-group of the following one.
So the cladogram represents the relationship between groups according to a derived character.
The derived character is any trait that a group passes to the descendants. Through evolution, the characters change, and new changes are added. When referring to a derivate character, we mean that all the subsequent species in the cladogram carry the trait.
A cladogram provides an image of how new species keep characters that were inherited from older species.
In the attached cladogram, you can see that the lungs are the derived character that distinguishes the salamander from the perch.
Claws or nails separate salamander from lizards.
Fur separates birds and reptiles from mammals.
Jaws separate hagfish from perch.
Mutations occurred in evolution producing new traits, and these traits also appear in posterior groups. So, after the hagfishes emerged the jaws, and all the animals that followed the hagfishes have jaws.
Lungs appeared after the perch and before salamander, so salamander, and all the posterior animals, have lungs. And so on.

Sound is another form of kinetic energy--it's air in motion. space heater- Space heaters work by utilizing convection or radiant heating. Radiant heaters emit infrared radiation into the room that directly heats objects and people who are close to them. One way to generate electricity is to burn solid waste, like the material found in landfills. ... That thermal energy is transformed into electrical energy, usually by turning a turbine. Another energy resource that comes from our garbage is the methane gas that is produced as the waste decays. A television set is another device that operates by the transformation of energy. An electrical beam from the back of the television tube strikes a thin layer of chemicals on the television screen, causing them to glow. In this case, electrical energy is converted into light.

The idea that the brain of an infant is like a blank slate is known as: ____
a- tabula rasa
b-dry cup
c-cogito ergo sum
d-the empty brain
Answer:
a
Explanation:
The idea that the brain of an infant is like a blank slate is known as Tabula rasa. It is given in Locke's philosophy. Thus, the correct option is A.
What is Tabula rasa?Tabula rasa is the theory which describes that individuals are born without a built-in mental content, and therefore all the knowledge comes from experience or perception in life. The epistemological proponents of the tabula rasa disagree with the doctrine of innatism, that holds the fact that the mind is born already in possession of certain knowledge eithout experience.
In Locke's philosophy, tabula rasa was the theory that at birth the infant mind is a blank slate without rules for processing data, and the data is added and rules for processing are formed solely by one's sensory experiences in life.
Therefore, the correct option is A.

5.DNA and RNA are both made up of nucleotides. RNA is comprised of adenine, uracil, guanine, and cytosine. DNA is made up of adenine, thymine, guanine, and cytosine. DNA is a double-stranded chain of nucleotides comprised of base pairs that form a double helix. RNA is often a single-stranded chain of nucleotides.
6.The central dogma states that DNA contains the genetic code needed to make proteins—a process known as gene expression. Transcription and translation are the two steps involved in gene expression. In transcription, the DNA code is turned into RNA. In translation, the RNA sequence provides instructions to the cellular machinery to manufacture polypeptides, which become proteins.
7.Replication is the duplication of DNA, and it is important because, in cell division, each daughter cell must contain an exact copy of the original cell's DNA, since DNA contains the instructions required to make all of the cell's tissues. Recombination is the natural process for genetic sequences in a chromosome or between chromosomes to exchange genetic information. Recombination is important in nature because it produces genetic variations that may be preserved because of natural selection. Recombination also can be used in the laboratory to combine the genetic code of two different organisms.

5. Why is it important to control the species population?
The pH of a solution is a measure of how acidic or basic it is. The greater the pH, the more basic the solution is. Corals and other marine invertebrates require less energy to make their exoskeletons and shells when ocean water is slightly basic. As carbon dioxide concentrations in Earth’s atmosphere rise, ocean water absorbs carbon dioxide and becomes more acidic. This process is called ocean acidification. How do you think ocean acidification will affect the coral reef?
Explanation:
Because coral reefs have limestone (calcium carbonate), the coral reefs will be greatly affected. The increase in hydrogen ions in the ocean will corrode the coral reef, making it inhabitable for species. This will affect the crabs that get their food and the community that lives within in it. Making countless of species to loose their lives and their way if living.
