The answer is <u>fishes</u>. Fish are unique in the aspect that they are the only vertebrates that blood circulates directly from respiratory organs to body tissues without returning to the heart first.
Answer:
Explanation:
Normally, under anaerobic condition in yeast, pyruvate produced from glycolysis leads to the production of ethanol as shown below.
pyruvate ⇒ acetaldehyde + NADH ⇒ ethanol + NAD
The pyruvate is converted to acetaldehyde by the enzyme, pyruvate decarboxylase. It should be NOTED that carbon dioxide is released in this step. The acetaldehyde produced in the "first step" is then converted to ethanol by the enzyme alcohol dehydrogenase. It must be noted from the above that the steps are irreversible.
If a mutated strain of yeast is unique because it does not produce alcohol and lactic acid (which is referred to as toxic acid in the question); thus having a high level of pyruvate because of the presence of a novel enzyme. <u>The function of this novel enzyme will most likely be the conversion of acetaldehyde in the presence of carbondioxide back to pyruvate; thus making that step reversible</u>. This could be a possible explanation for the high level of pyruvate present in the yeast.
As there are no answer choices, I'm going to answer this just based off my knowledge
Analogous structures suggest convergent evolution because they have both evolved from a set of species but for different reasons and from different causes.
Answer:
I might be wrong but im guessing 600
Explanation:
Since there is one molecule of glucose used per 6 molecules of carbon dioxide released, if you have 100 molecules of glucose, then you multiply the carbon dioxide by 100 which is 600. Thats what I would say but I might be wrong.
In a particular context, “epoch” can refer to a particular point of time characterized by a particular event/series of events.
While “era” refers to a period of time characterized by events in a chronological order.
Thus, an “era” can encompass more than one “epoch”.
“Period” can refer to a short interval of time or a very long interval of time.
For example:
<span>“My period of happiness….”“The period of Four Horsemen…”</span>
<span>“Eon” </span>refers to an indefinitely long time. <span>Eon is presumed to consist of at least 2 eras.</span>
