Answer:
I would expect that the sample has only 50% of the original 235 U.
Explanation:
That is because 235 U has a half-life of 700 million years and I expect that my sample be 350 million years old. 350 is half of 700.
Answer:
Error: The Methionine at the end of the chain
Explanation:
Hello! Let's solve this!
The start codon is AUG, this codon encodes Methionine. Therefore all proteins will start the amino acid sequence with Methionine.
In this case, the student placed the Methionine at the end of the chain, so that is the mistake. Methionine goes to the beginning of the chain.
The correct option is this: THE MASS OF THE PROBE REMAINS THE SAME, BUT THE WEIGHT OF THE PROBE DECREASES.
The mass of an object is a measure of the amount of substance it contains and this amount always remain the same unless there is a change in quantity of matter. This is the reason why the mass of a substance will remain constant, no matter where it is placed, whether on planet earth or on another planet. The weight of a substance on the other hand is a force, whose value depends on the force of gravity. Thus, the force of gravity that exist in the place, where the object is placed will determine its weight.
Answer:
The only possible answer is D, which states that the population will reach 5000 and after that the growth will stabilise (exactly what would hapen in a logistic growth).
