The answer is B. This is called genetic shift. The pups with
advantageous traits are able to survive until the age of reproduction hence able
to pass their genes to the next generation. Few and fewer pups with disadvantageous
traits will get to reproduce hence the allelic frequencies of the shark population
will shift in favour of increased hunting efficiency.
1) a series of circulation cells for the tropics, (2) a series for the polar regions and (3) a very dynamic series of cells in the midlatitudes
The answer is Satellites because they help with transmitting radio rays so that we can communicate with one another.
Answer:
For a scientific hypothesis to be useful, it must be a
<u>testable</u> explanation of facts
Explanation:
In the scientific method, the hypothesis represents the starting point of all research, where the observation of a phenomenon is followed by a possible explanation that must be measured and proven.
It is important that the hypothesis presents defined, specific and real variables, and there must be the possibility of test it and have the necessary tools for this purpose.
Regarding other options:
<em> A. Provable
: the probability of a hypothesis implies that it may or may not be true.</em>
<em> B. Widely accepted
: the explanation that provides a hypothesis needs to be demonstrated through experiments in order to be accepted.</em>
<em> C. Correct: the hypothesis will not be correct until it has been tested.</em>
