Answer:
a. she has constructively evicted Steve.
Explanation:
Steve leases an apartment from Ashley. According to the lease, Ashley is required to keep all plumbing in working order. After Steve has lived in the apartment for four months, the toilet breaks. Ashley refuses to fix it and thereby makes it virtually impossible for Steve to continue to live there. The result of Ashley's inaction is that she has constructively evicted Steve.
Constructive eviction is a term which is used to refers a circumstance inwhich a landlord fails to provide or do something in his or her apartment thereby rendering it uninhabitable by tenants.
A drop in pH would make protonation more likely, and a protonated proximal histidine would not be able to donate its electron density to the iron atom.

What is the role of proximal histidine in hemoglobin?</h3>
The first histidine that is bonded to Fe(2+) we call proximal, and the histidine that bonds last, to the oxygen, we call distal.
Histidine is an amino acid most people get from food. It's used in growth, repair of damaged tissues, and making blood cells.
It helps protect nerve cells. It's used by the body to make histamine.
In hemoglobin, the role of proximal histidine is to hold the heme group in the correct location on the hemoglobin chain.
The proximal histidine also pulls the iron in heme out of the plane of the heme molecule. This iron will be pulled back into the plane when it is oxygenated.
The proximal histidine strengthens the iron-imidazole bond and helps to stabilize the oxidoreductase in its higher oxidation (i.e. compounds I and II) states.
