Professor Chapman is very friendly with her students, allowing them extra time on assignments and giving them the freedom to come late to class whenever they want. Dr. Weldon, on the other hand, is much stricter in the classroom. She does not accept late assignments, tells students "be on time or don't come to class," and at least two students got no credit on the term paper because they turned it in a day late. Both professors teach with the same quality but are different in their interactions with students. When evaluation time comes, students tend to give Dr. Weldon far lower marks because they dislike her, not because she is a bad teacher. This is an example of the __________ effect.

Answers

Answer:

The correct answer is - This is an example of halo effect.

Explanation:

Halo effect is considered to be a cognitive bias in which we judge a person based on his behavior and character and make an impression in our mind about that person that the person is nice, good or bad.  

So it this case students have got a bad impression of Dr. Weldon because she does not accept late assignments, tells students "be on time or don't come to class," and at least two students got no credit on the term paper because they turned it in a day late.

So when evaluation time comes, students tend to give Dr. Weldon far lower marks because of the halo effect.

Answer:

The Halo Effect.

Explanation:

She seems nicer, kids like her better. That's basically what it sums up to.

Hope this helps. :)

What does the respiratory system eliminate when there is an excess of hydrogen ions in the body?

Answers

Answer:by breaking down carbonic acid into carbon dioxide and water.

The carbon dioxide is expelled from the body

Explanation:the body is able to maintain a constant internal environment through hoemostatis.one of such control is the acid-base balance in the body.

It does this by regulating the amount of hydrogen ions in the blood.A low pH indicates an acidic condition and a high pH indicates an alkaline condition.

The human blood has a pH of 7.35---7.45.it is slightly alkaline and needs to keep this range constant.

The lungs and kidneys involved in regulating the body pH.

When there is excess hydrogen ion in the blood, bicarbonate ions combine with the hydrogen ions to form carbonic acid . this carbonic acid breaks down into water and CO2 .the co2 is expelled from lungs through gaseous exchange.

When the accumulation of acid in the blood is high,the pH drops below 7.35 and this is called respiratory acidosis.

When there is excess alkaline in the blood,the pH goes beyond 7.45 and this is called respiratory alkalosis.
