Taking into account the Brønsted-Lowry acid-base theory:
H₂Se behaves like acid because donates an H⁺ proton while H₂O behaves like base because accepts an H⁺ proton from the acid.H₃O⁺ is the conjugate acid of the H₂O and SeH⁻ is conjugate base of H₂Se.
The Brønsted-Lowry acid-base theory (or the Brønsted-Lowry theory) identifies acids and bases based on whether the species accepts or donates protons or H⁺.
According to this theory, acids are proton donors while bases are proton acceptors. That is, an acid is a species that donates an H⁺ proton while a base is a chemical species that accepts an H⁺ proton from the acid.
So, reactions between acids and bases are H⁺ proton transfer reactions, causing the acid to form its conjugate base and the base to form its conjugated acid by exchanging a proton.
In other words, a conjugate base is an ion or molecule resulting from the acid that loses the proton, while a conjugate acid is an ion or molecule resulting from the base that gains the proton:
acid + base ⇄ conjugate base + conjugate acid
In this case, you know:
H₂Se + H₂O → SeH⁻ + H₃O⁺
H₂Se behaves like acid because donates an H⁺ proton while H₂O behaves like base because accepts an H⁺ proton from the acid.
So, H₃O⁺ is the conjugate acid of the H₂O and SeH⁻ is conjugate base of H₂Se.

which of the following is most likely the main claim that the writer is planning to make in the new version of the passage?
People often have different view. when it comes to writers. There is no much difference. Opinion and views differs from person to person. The writer's main claim or thesis in the new version of the passage is Da Vinci was a great artist because he had exotropia.
Exotropia is simply known to be a type of defect where the eyes are not align thag is one eye pushes outward. This form of outward pushing or deviation may be constant or intermittent.
The writer of the passage, claimed that Da Vinci's physical defect of exotropia was one of the main reasons for his success.
Conclusively, Humans can based their beliefs on what they see, know or studied. the writer choose to base the success of Da Vinci on his physical appearance.

https://brainly.com/question/19142980
The full passage is below
(1) For centuries, art scholars have studied the renowned works of Leonardo da Vinci, the Renaissance artist, pondering how he created three-dimensional figures with such depth on flat canvases. (2) If da Vinci did have exotropia, in which an eye turns outward, he would not have been the only artist in history with that condition.
(3) Christopher Tyler, a visual neuroscientist at City University of London, noticed a pattern in da Vinci’s portraits and in works depicting the great artist. (4) While few self-portraits of da Vinci exist, Tyler argues that many of da Vinci’s portraits reflect his appearance. (5) As the great artist himself said, the soul “guides the painter’s arm and makes him reproduce himself, since it appears to the soul that this is the best way to represent a human being.”
(6) To test his theory that da Vinci had exotropia, Tyler studied the eye alignments of the subjects of six pieces of art that purportedly depict the Renaissance artist himself, including da Vinci’s Vitruvian Man and Salvator Mundi and Andrea del Verrocchio’s sculpture David. (7) The results confirmed Tyler’s suspicions: da Vinci likely had exotropia, with one eye turning out at -10.3 degrees.
(8) Tyler’s findings, which he published in JAMA Ophthalmology, created a stir in both the art and science communities. (9) Only about 1 percent of the population has exotropia, yet previous studies have suggested that other famous artists—like Rembrandt, Picasso, and Degas—had it as well, which indicates that the eye condition was more common in centuries past than it is now. (10) Tyler believes that da Vinci’s condition was intermittent—that is, his eye drifted out of alignment when he was relaxed, but when he focused, it would realign. (11) If Tyler is right and da Vinci could control his exotropia, then the artist could switch from 2-D to 3-D vision, enhancing his ability to accurately capture three-dimensional figures on a two-dimensional canvas.
The writer is working on a revision of the passage and has written the following thesis statement for it.
Based on the evidence from Tyler’s studies, it is clear that this condition was the primary reason for da Vinci’s success.
Which of the following is most likely the main claim that the writer is planning to make in the new version of the passage?
A The only way for an artist to be successful is to have exotropia.
B. Da Vinci was more successful as an artist than others who also had exotropia.
C. Studying just a few works of art can provide compelling information about an artist’s physical conditions.
D. The only way to fully understand an artist’s work is to study the artist’s physical conditions.
E. Da Vinci was a great artist because he had exotropia

a small amount of sodium hydroxide is added to water. when the chemical reaction reaches equilibrium, the ph is 12. which statement and conclusion about sodium hydroxide is correct?
The correct statement and conclusion about sodium hydroxide (NaOH) is: The negative log of the concentration of [tex]OH^-[/tex] ions is 12, so Sodium hydroxide is a strong base.
In Chemistry, pH literally means the power of hydrogen ions and it can be defined as a measure of the molar concentration of hydrogen ions in a particular solution, thereby, specifying the following;
The acidity of a chemical solution.The neutrality of a chemical solution.The basicity (alkanility) of a chemical solution.On a related note, a pH scale is a scale that is used to measure the concentration of hydrogen ions in both acidic and basic (alkaline) solutions.
Generally, a pH scale is calibrated with a standard measurement that ranges from 0 to 14.
On a pH scale, a solution with a pH of 7 is neutral, a solution with a pH below 7 is acidic and a solution is considered to be basic (alkaline) when its pH is above 7.
In this experiment, a small amount of sodium hydroxide is added to water, to give a pH of 12 when the chemical reaction reaches equilibrium.
Hence, the negative log of the concentration of [tex]OH^-[/tex] ions is 12, so Sodium hydroxide is a strong base.

what would be the outcome of the processes shown above if the mrna never moved outside of the nucleus?
Answer:See below
Explanation:
The process of protein synthesis initiates with the transcription process in the nucleus and continues with the translation process in the cytoplasm. If the mRNA never left the nucleus, the translation would not be possible.
-------------------------------------
The protein synthesis process involves transcription and translation.
Transcription:
Transcription is the copying process of the DNA section for the desired protein occurs.
It happens in the nucleus, where the template DNI strand is read in direction 3´→ 5´ to build the mRNA molecule in direction 5´→ 3´.
Once the transcription is over, the new mRNA molecule leaves the nucleus and goes to the cytoplasm.
Translation:
Translation occurs in the cytoplasm when mRNA meets a ribosome.
rRNA and tRNA read mRNA in the direction 5´→ 3´ to build the protein.
While the ribosome reads mRNA strain from its 5´ extreme to 3´, tRNA adds the correct amino acids to build the polypeptide.
Protein growth initiates in the AUG start codon -Metionin-, and ends when reaching either of the stop codons UAA, UAG, UGA.
If the mRNA does not move outside of the nucleus, the translation process is not possible. Only transcription would occur, but no translation. Protein synthesis could not be accomplished.

generally reduces the number of hurricanes formed in the atlantic ocean results in a more active tornado season can lead to crop damage and landslides in california
Based on meteorological information El Nino generally reduces the number of hurricanes formed in the Atlantic ocean.
This is because the impact of El Nino quells the Atlantic hurricane effect. This is done by raising the quantity of sinking motion and improving atmospheric resilience.On the other hand, La Nina results in a more active tornado season.
This is because the La Nina effect pushes the jet stream to move towards the north, and subsequently, this effect reduces around the Pacific side.Excessive rainfall can lead to crop damage and landslides in California.
This is because continuous rainfall at a certain level in California leads to erosion which can damage crops. Subsequently, continuous rainfall of about two weeks can turn erosion into landslides in California, particularly the southern side.Hence, in this case, it is considered that different climatic conditions affect the physical environment of humans.
