The correct answer is A.
Toxins and various pollutants increase in concentration through the food chain in a process called biomagnification. This means that the organisms on the top of the food chain, like the herring gull, have many times greater concentration of toxins than the lower food chain level organisms because they prey on lower food chain level organisms. If a herring gull ears 100 herrings, it will have a 100x times greater concentration of toxins in its body than a herring.
This is (b.) False, because it was actually introduced in the 1930's.
For centuries scientists thought the Universe always existed in a largely unchanged form, run like clockwork thanks to the laws of physics. But a Belgian priest and scientist called George Lemaitre put forward another idea. In 1927, he proposed that the Universe began as a large, pregnant and primeval atom, exploding and sending out the smaller atoms that we see today.
His idea went largely unnoticed. But in 1929 astronomer Edwin Hubble discovered that the Universe isn’t static but is in fact expanding. If so, some scientists reasoned that if you rewound the Universe's life then at some point it should have existed as a tiny, dense point. Critics dismissed this: the celebrated astronomer Fred Hoyle sarcastically called this concept the “Big Bang Theory"
Answer:
All the answers are correct
Explanation:
An inhibitor of carbonic anhydrase would interfere with oxygen binding to hemoglobin, increase blood pH due to increased H+, increase the amount of bicarbonate formed in the blood and decrease the amount of carbon dioxide dissolved in plasma.
Carbonic anhydrase catalyses the reaction between carbon dioxide and water to form carbonic acid. Carbonic acid dissociates to form hydrogen carbonate ions and hydrogen ions. The hydrogen ions combine with haemoglobin to form weak haemoglobinic acid.
