Answer:

This is an incomplete question.

Below should be the complete one with options:

A researcher introduces a signal produced by bacteria to eukaryotic cells that she is culturing in the laboratory. Remarkably, she notices that this signal results in an increase in eukaryotic gene expression. How is this possible?

A.This gene expression is likely independent of the presence of the prokaryotic signal.

B.The signal is either similar in structure to a ligand used by eukaryotes, or this signaling pathway is utilized by both prokaryotes and eukaryotes.

C.This signaling pathway might actually be utilized by both prokaryotes and eukaryotes.

D.This signal is likely similar in structure to ligands utilized by eukaryotic cells.

E.This prokaryotic signal likely travels directly into eukaryotic cells and acts as a transcription factor.

THE CORRECT ANSWER IS B

B.The signal is either similar in structure to a ligand used by eukaryotes, or this signaling pathway is utilized by both prokaryotes and eukaryotes.

write an outline that shows how you could structure the arguement you are crafting either inductively or deductively. If you are
BaLLatris [955]

Answer:

An inductive argument is the one that, from the observation of a

property defined in a sufficient number of individuals of a

determined class, generalizes in the conclusion the property

observed and attributed to all members of that same class.

This generalization applies to both the observed cases and to

all of its kind not observed.

Unlike deductive arguments, the conclusion of which is not

offers new information and therefore its conclusions are necessary,

inductive arguments in their conclusion offer us information

new, that is, information not included in the premises, and therefore its

Conclusion is likely. What is that new information? The one that

refers to cases not observed, but from which we infer

they also own the property attributed to the cases observed; from

In this way we generalize the properties observed in all

members of that class, including cases not observed. This is the

information not included in the premises and that forces us to

put the word "probably" before our conclusion, because

It is possible that, when reviewing cases not included in the

premises, these do not comply with the attributed property and then the

conclusion is not true; that's why we just presume that the

Conclusion is likely and not necessary.
