Answer:
Option E, leaves more viable offspring than others of its species
Explanation:
A fit species is one that is able to survive in adverse conditions when most of its other mates fail to do so.
The species which is strong and viable enough to feed itself and reproduce successfully emerge as a fit species. Likewise, the offspring of fit species are viable and fit enough to survive, feed themselves and further reproduce successfully.
Hence, option E is correct
Explanation:
In a DNA molecule, Adenine forms hydrogen bonds with Thymine and Cytosine forms hydrogen bomds with Guanine.
However in mRNA, Thymine becomes Uracil (T => U)
Therefore every A in the DNA sequence becomes U,
every T in the DNA sequence becomes A,
every C in the DNA sequence becomes G,
every G in the DNA sequence becomes C.
The answer is A.
Answer: C. scorpions have changed as a result of natural selection
Explanation:
The text tells us that scorpions today are now smaller than they were in the past. This means that the scorpions have changed since then i.e. they have evolved.
The primary reason for evolution is natural selection which refers to a situation whereby only the organisms that are better adapted in their species survive.
The conclusion that can be drawn from this research therefore is that we have smaller scorpions today because they stood a better chance of survival than the larger ones and so survived whilst the larger ones died out.
