<span>The fourth level of cell organization is the
organ level. The organ level is a structure composed of collections of tissues
that perform specific functions in a living organism. Organs that are found in
a human body are the heart, lungs, brain, pancreas, liver, among others. These
organs perform specific functions and work in an interconnected manner for the
human body to function well. When organs work together, they are called organ
systems which are already the fifth level of cell organization.</span>

Answer:it should be a right triangle because
12.5²+30²=32.5²
area of the triangle=
This is referred to as Sleep Apnea.
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.
