Answer:
The formation of one isochromosome
Explanation:
In cytogenetics, an isochromosome is a structurally abnormal chromosome that renders two chromosome arms which are identical inverses of each other. An isochromosome is caused by simultaneous duplication and deletion of genetic information during DNA replication. The resulting isochromosome will contain two identical copies of either the long or short chromosome arms that are disposed as a mirror image.

What work did Francis Bacon do with the design and organization of libraries ?
The correct answer to this open question is the following.
What Francis Bacon did with the design and organization of libraries was that he created a classification for books and texts, that served as an influence for the way big libraries, such as the Library of Congress classifies books.
Francis Bacon (1561-1626) classified his books into three categories: reason, memory, and imagination. This system was first copied by antifederalist politician Thomas Jefferson to organize his library. In the end, Thomas Jefferson developed a big catalog with 44 categories. That is how Francis Bacon influence the design and organization of libraries.

What helps the plasma membrane function? channels and chain-like structures O pumps and gelatin-like material O nuclei and endoplasmic reticula O chloroplasts and mitochondria
Answer:
channels and chain-like structures
Explanation:
The plasma membrane contains channels that favor the transport of materials from both sides, i.e., from the intracellular medium to the extracellular environment. Membrane channels are a class of proteins that enable the passive transport of ions and chemical compounds by using the electrochemical gradient in both sides of the membrane. For example, channel proteins in the cell membrane known as aquaporins enable the transport of water across the cell membrane much more rapidly than by diffusion across this barrier.
What is the pH of a 0.00125 M HCl solution?
Answer:
[tex]pH=2.9[/tex]
Explanation:
Hello,
In this case, the pH is computed by:
[tex]pH=-log([H^+])[/tex]
Whereas the concentration of hydrogen ions equals the concentration of the acid for strong acids such as hydrochloric acid (HCl) due to its complete ionization in solution, which means that such concentration is 0.00125 M. Thus, the pH turns out:
[tex]pH=-log(0.00125)\\\\pH=2.9[/tex]
Regards.
By definition, the pH of a 0.00125 M HCl solution is 2.90.
You need to know that pH is the Hydrogen Potential. It is a measure of acidity or alkalinity that indicates the amount of hydrogen ions present in a solution or substance.
Mathematically, pH is calculated as the negative base 10 logarithm of the activity of hydrogen ions:
pH= - log [H⁺]
The numerical scale that measures the pH of substances includes the numbers from 0 to 14. The pH value 7 corresponds to neutral substances. Acidic substances are those with a pH lower than 7, while basic substances have a pH higher than 7.
On the other side, a strong acid is an acid that dissociates completely in solution at constant temperature and pressure. Under these conditions, the concentration of a strong acid is equal to the concentration of hydrogen ions (Hydronium or H₃O⁺).
In this case, HCl is a strong acid. Then: [HCl]= [H⁺]= 0.00125 M
Reeplacing in the definition of pH:
pH= - log 0.00125 M
Solving:
pH= 2.90
Finally, the pH of a 0.00125 M HCl solution is 2.90.

B. Stored energy decreases from Consumer 2 to
Consumer 3.
C. Stored energy increases from Producer to
Consumer 1.
D. Producer organisms contain the least amount of
stored energy.
Answer:
B. Stored energy decreases from Consumer 2 to
Consumer 3.
Explanation:
As energy is transferred from one trophic level to another on the pyramid, the amount of stored energy available for those above a trophic level decreases.
The greatest amount of energy is found at the bottom of the pyramid, where we have the producers.
Consumers at the top of the pyramid have the least amount of stored energy.
The statement that is correct about the pyramid is: "B. Stored energy decreases from Consumer 2 to
Consumer 3."

In this week's experiments, if you replaced glucose with the monosaccharide fructose, predict the results for fructose transport under all 4 conditions. Explain your prediction.
Answer: Fructose is transported by facilitated diffusion.
Explanation:
Glucose is a monosaccharide with the molecular formula C6H12O6.3 It is a hexose. It is a form of sugar that is found freely in fruits and in honey. Its energy yield is 3.75 Kcal/g under standard conditions.
Fructose is a type of carbohydrate found in vegetables, fruits, and honey. It is a monosaccharide with the same molecular formula as glucose, C6H12O6, but with a different structure, that is, it is an isomer of glucose. Its energetic power is the same as that of glucose, 4 kilocalories per gram, and it is a reducing carbohydrate.
Glucose is the main energy substance of a cell and for its entry it requires a transport protein in the cell membrane, called transporter. The transport of glucose through the cell membrane is carried out by two families of membrane proteins:
Sodium-coupled glucose transporters (SGLT sodium-glucose-transporters), which involves the co-transport of Na+ by the SGLT-1 by maintaining the Na+ gradient thanks to the Na+/K+ pumpGlucose transport facilitation proteins (GLUT)On the other hand, fructose is absorbed by another type of transporter, called Glut-5, a protein that crosses the membrane 12 times. Finally, the passage of both glucose and fructose into the blood takes place through the Glut-2, a transporter with low affinity and high transport capacity.
If any Glut is considered within the context of a large family of proteins, it can be immediately noticed that they all possess common characteristics that in biochemical terms are called "molecular signature of glucose transporters" and that it is no more than a set of extremely conserved primary amino acidic sequences that determine secondary and tertiary structures (domains or motifs) that are responsible for the functional characteristics of the protein.
Facilitated diffusion is a type of cellular transport where the presence of a carrier or transporter (integral protein, Glut is this example) is necessary for substances to cross the membrane. It happens because the molecules are larger or insoluble in lipids and need to be transported with the help of membrane proteins. So, in the first step, fructose binds to the transport protein, and this changes shape, allowing the passage of this sugar. In this way, fructose concentrations inside the cell are always very low, and the external and internal concentration gradient favours diffusion.
Summarizing, fructose is transported by facilitated diffusion. So if we replaced glucose with fructose we would have seen no change in each conditions. And since fructose is transported by this type of mechanism, there is not a concentration gradient.
NEED ANSWERED ASAP The food webs below model relationships among the organisms in two ecosystems. Which ecosystem would be more likely to survive if a disease killed the grasses? A) The forest ecosystem, because most of the animals can eat other organisms B) The grassland ecosystem, because several predators compete for food C) The forest ecosystem, because it has three top predator D) The grassland ecosystem, because it has many herbivores
The correct answer is A) The forest ecosystem, because most of the animals can eat other organisms.
Explanation:
The web food of the forest ecosystem shows only crickets and mice need exclusively grass, while in the grassland ecosystem there are four different animals that feed exclusively on grass. Also, in the grassland ecosystem, these four organisms are the food for other animals. This means if there was no grass all organisms in the web will be negatively affected.
This phenomenon would not occur in the forest ecosystem because even if crickets and mice cannot feed on grass and they disappear in the ecosystem, their predators such as raccoons or skunks can eat other organisms such as ducks or squirrels that do not depend on the grass. Moreover, organisms such as butterflies or mosses that depend on grass and other types of vegetation can survive. According to this, the ecosystem that would most likely survive is the forest because most animals can eat other organisms (Option A.)
the answer is A
i mean, if you think about it-
obviously D. and B. grassyland ecosystem, wouldnt survive. cause they live off grass. so eliminate that. now we have: C and A.
now lets look. eliminate C. why? well cause just because it has top 3 predators, it doesnt mean it will survive. now bOoM. your answer is A.

Rr can only segregate as R and r
RrYy can segregate as RY, Ry, rY, and ry
rrYy can only segregate as rY and ry
RrYY can only segregate as RY and rY
RrYyBb can segregate as RYB, RYb, RyB, Ryb, rYB, rYb, ryB, and ryb
Each of the diploid genotypes are:
R and r RY, Ry, rY, and ry rY and ry RY and rY RYB, RYb, RyB, Ryb, rYB, rYb, ryB, and rybAccording to Mendel's Law of Segregation.
What is Mendel's law of segregation assortment?
For the F2 generation, the law of segregation requires that each gamete acquire either an R allele or an r allele along with either a Y allele or a y allele.
The law of independent assortment says that a gamete into which an r allele is sorted would be equally likely to contain either a Y allele or a y allele.
Thus, is based on Mendel's law of segregation assortment.

We are trying to determine the possible modes of inheritance for some particular human disorder. We have a very small pedigree for this disorder. Assuming the pedigree is accurate, indicate which of the modes of inheritance are consistent with this pedigree:
Answer:
The correct choices will be "X-Linked Recessive".
Explanation:
The heritage couldn't predominate because it would not be prevalent or observable in every decade at least. This could be a recessive gene, then. It would be a recessive condition related to X as it affects only individuals (male).X-Linked succession characteristics measured by chromosome-transported alleles become responded to although the X-linked.
