Answer:
The reason why the imidazole side chain of histidine can function as either acid or base catalyst is: I and II: Option A.
Explanation:
The imidazole group of the histidine has a pKa of 6.0, which is closer to the pKa of the physiological environment. Thus, at every reaction, either acidic or basic, the side chain act as a buffering catalyst, which can be useful irrespective of the pH of the reactants. Also, since the reaction of a catalyst is influenced by the pH of the environment, at physiological pH, the sulfur in the ring can be protonated by acidic reaction or deprotonated by the primary reaction within the physiological environment.
In normal conditions, warm water does "pile up" in the" Western Pacific Ocean.
CuCl₂ copper (II) chloride
Ba(OH)₂ barium hydroxide
<u>net ionic equation</u>:
Cu²⁺ (aq) + 2 Cl⁻ (aq) + Ba²⁺ (aq) + 2 (OH)⁻ (aq) → Cu(OH)₂ (s) + 2 Cl⁻ (aq) + Ba²⁺ (aq)
where:
(aq) - aqueous state
(s) - solid
Answer:
b) Industrial farming
Explanation:
The term “industrial agriculture” refers to the type of farming which raises and cultivates large numbers of livestock and plants in high-density environments. It uses modern technology to promote faster growth and reduce illness and death rates in livestock, creating food products on a mass scale.
