I am pretty sure that a point mutation that creates a premature stop codon is called a synonymous mutation. It also can be called silent mutation, if you have it in you option list, feel free to use it, it is the same. That will definitely help you.
Answer:
First, second, and last are correct statements.
For accuracy and reliability of any experiment, a number of observations must be as large as possible. It reduces the effect of any observation or any event which might have happened by chance or error.
Thus, finches were better to record observations as they were available in large number as compared to the tortoise.
In addition, the life cycle of birds is smaller as compared to the tortoise which enabled the scientists to observe more generations.
Lastly, the birds were easy to capture and track as compared to the tortoise. Tortoise being an amphibian could live on land as well as in water which made it difficult to track them.
Answer:
Option D is false
Option E is false since it is incomplete
Option C is false
Explanation:
Well, regarding option D it is considered false because the functional groups would be:
Acetone (which is not used as an energy source, is exhaled or excreted as waste), Betahydroxybutyrate and acetoacetate (if not oxidized to be used as an energy source).
In statement C it is false, because the formation of ketone bodies increases with the presence of acetylcoA, but acetone is one of those that will always be witnessed in a lower percentage, since it is excreted by the body as waste, both either by the airways in the exhalation (characteristic ketone breath) and in the urine (cetouria)
And as for the E option, I consider it false because the ketone groups are formed in the liver and kidney.
Greater proportion in hepatic mitochondria and to a lesser extent in the kidney
