Answer:
The modified hemoglobin with free imidazole cannot be expected to show cooperativity in oxygen binding. The movement of iron ion takes place up in the plane of heme when binding of one subunit of hemoglobin takes place with oxygen. One of the iron's and oxygen's axial ligands comprise the proximal histidine's imidazole ring.
With the movement of iron into the hemoglobin ring, the pulling of proximal histidine takes place along with it. Therefore, when binding of oxygen takes place with one subunit, a modification also takes place in the intersubunit associations, this also comprises displacement of the alpha helix. This phenomenon plays an essential role in modifying the hemoglobin's tensed state to the relaxed state. The withdrawal or mutation of the imidazole ring from the histidine residue does not further permit the cooperative binding as it is not associated physically with the alpha-helix.

ANSWER FOR NUMBER 14 The arrows show in the food web what animals eat/get eaten by, and why the arrows can't point the other way is because if they were to point the other way it would be unaccerate, for example if we switch the arrows that means that a hawk would be eaten by a rat.
Explanation:
So yea I hope that helped, I'm not really good w words when it comes to science.
The question is incomplete as it does not have the option which are:
1. Halo
2. Leniency
3. Central tendency
4. Recency
Answer:
Leniency
Explanation:
A perceptual error is a phenomenon which occurs when the person holds some preconceived ideas about some other person on the basis of which the person is not able to make accurate perceptions about the person.
In the given question since the Dr. has not given less than B grade, this could be the result of the Halo type of perceptual error in which the person assumes that one parameter can be responsible for all other parameters and the person make incorrect errors like he could have considered attendance as a parameter ad on the basis of that he could have become more lenient towards the student with full attendance.
Thus, Leniency is the correct answer.
