De acuerdo con lo anterior llene el siguiente cuadro comparativo señalando con x si las células procariotas o eucariotas posee las estructuras mencionadas
Answer:
El cuadro no está presente pero las diferencias principales entre células eucariotas y procariotas son:
Eucariotas:
Tienen núcleo
Tienen organelas
Tienen Vacuolas
Tienen Citoesqueleto
Tienen Cloroplastos
El ADN está asociado a proteínas
El ADN es lineal
Presentan mitocondrias
Presentan un sistema de endomembranas
Procariotas:
No tienen núcleo
No tienen vacuolas
No tienen cloroplastos
No tienen organelas
El ADN no está asociado a proteínas
El ADN es circular
Presenta mesosomas
Explanation:
Las células procariotas son más primitivas que las eucariotas, por ende, sus estructuras son más simples. Las células procariotas están en organismos unicelulares tales como las bacterias, mientras que las células eucariotas están en organismos unicelulares y pluricelulares como en plantas, animales, u hongos. La diferencia más notoria entre ambos tipos de células es la ausencia de núcleo en las procariotas haciendo que el ADN está disperso en el citoplasma mientras que en las células eucariotas, el ADN está dentro del núcleo celular.

25 Zoogeographic regions are characterized by the presence of specific groups of animals. These
regions are determined by the taxonomic or phylogenetic relationships of animals. The map
shows the zoogeographic regions proposed by the naturalist Alfred Russel Wallace in 1876.

Palearctic

The similarities of organisms in which two areas numbered above provide the best evidence
for common ancestry between the organisms in both locations?
Aim
When dividing the world into zoogeographical regions, Alfred Russel Wallace stipulated a set of criteria by which regions should be determined, foremost the use of generic rather than species distributions. Yet, recent updates of Wallace's scheme have not followed his reasoning, probably explaining in part the discrepancies found. Using a recently developed quantitative method, we evaluated the world's zoogeographical regions following his criteria as closely as possible.
Location
Global.
Methods
We subjected presence–absence data from range maps of birds, mammals and amphibians to an innovative clustering algorithm, affinity propagation. We used genera as our taxonomic rank, although species and familial ranks were also assessed, to evaluate how divergence from Wallace's criteria influences the results. We also accepted Wallace's argument that bats and migratory birds should be excluded (although he was contradictory about the birds) and devised a procedure to determine the optimal number of regions to eliminate subjectivity in delimiting the number of regions.
Results
Regions attained using genera (eight for mammals and birds and six for amphibians) strongly coincided with the regions proposed by Wallace. The regions for amphibians were nearly identical to Wallace's scheme, whereas we obtained two new ‘regions’ for mammals and two for birds that largely coincide with Wallace's subregions. As argued by Wallace, there are strong reasons not to consider these as being equivalent to the six main regions. Species distributions generated many small regions related to contemporary climate and vegetation patterns, whereas at the familial rank regions were very broad. The differences between our generic maps and Wallace's all involve areas which he identified as being uncertain in his regionalization.
Main conclusions
Despite more than 135 years of additional knowledge of distributions, the shuffling of generic concepts, and the development of computers and complex analytical techniques, Wallace's zoogeographical regions appear to be no less valid than they were when he proposed them. Recent studies re‐evaluating Wallace's scheme should not be considered updates as such because they have not followed Wallace's reasoning, and all computer‐based analyses, including this one, are subject to the vagaries of the particular methods used.

Which of the following are techniques to estimate population size?
counting individuals
sampling
mark-and-recapture
population index
Answer:
The Mark-Recapture technique is used to estimate the size of a population where it is impractical to count every individual. The basic idea is that you capture a small number of individuals, put a harmless mark on them, and release them back into the population.
Two important measures of a population are population size, the number of individuals, and population density, the number of individuals per unit area or volume. Ecologists often estimate the size and density of populations using quadrats and the mark-recapture method.
Wildlife managers use 4 general approaches to estimate population sizes of wildlife: total counts, incomplete counts, indirect counts, and mark-recapture methods.
The answer is counting individuals and mark-and-recapture.
The technique counting individuals, sampling, mark-and-recapture, and population index are used to estimate population size.
What is population?A population is the entire set of individuals, whether that group is a nation or a group of people who share a characteristic.
To estimate population size, the following methods can be used:
Individual counting entails physically counting every individual in a population. This method is appropriate for small or sparsely populated areas.Sampling is the process of taking a representative sample of a population and extrapolating the results to estimate population size. This method is best suited for large or densely packed populations.Capturing and marking a sample of individuals, releasing them back into the population, and then capturing another sample later. The proportion of marked people in the second sample is used to calculate population size. This method is appropriate for populations that are difficult to directly count or sample.Population index: This method estimates population size by using indirect measures such as the number of nests or tracks. This method is appropriate for populations that are difficult to observe directly or for counting individuals. It is, however, less accurate than other methods.Thus, all the given options are correct.

Y red ballonls and m green ballons were divided evenly amoung three kids. How many ballons did each kid get
Answer:
Each kids will get Y red balloons + M green ballons ÷ 3.
Explanation:
This is because Y red balloons and green red balloons are the total number of balloons present.
The total number of ballons are Y red+M green ballons.
The total number of kids are 3.
Therefore each kids with get the addition of the ballons divided by 3.
Therefore, Y red ballons + M green ballons ÷ 3.

A cell's mRNA loses all of its uracil. What will happen next?
If a cell's mRNA loses all of its uracils, then it will not undergo a protein synthesis or translation process.
as defected mRNA will not be able to form all anticodon thus there is no codon formation takes place for protein synthesis.
What are codon and anticodon?Codon: A codon is a trinucleotide sequence of DNA or RNA that corresponds to a specific amino acid.
Anticodon: An anticodon is a trinucleotide sequence complementary to that of a corresponding codon in a messenger RNA (mRNA) sequence.
Hence, If a cell's mRNA loses all of its uracils, then it will not undergo a protein synthesis or translation process.

How would you convert a spring into a straight piece of metal using the same approach as topoisomerase in DNA replication?
Answer:
It would be necessary to make small breaks in the spring and then align the pieces, forming a straight piece.
Explanation:
Topoisomerase is the enzyme responsible for unwinding the DNA molecule during replication. To do this, topoisomerase makes small breaks in the DNA molecule, but uses covalent bonds to hold these small pieces of DNA, causing the strands of DNA to pass over each other, aligning in a rectilinear topography.
