During DNA replication, the two strands separate as the hydrogen bonds connecting the parent strands are broken by an enzyme called helicase. In the DNA molecule (double strand) complementary bases are joined by hydrogen bonds; that is; Adenine paired to thyamine and guanine to cytosine; during replication the enzyme helicase separates the double helix by breaking the hydrogen bonds between the complementary bases.
I think B. Fruits develop from ovary walls... I think this because it does not accurately describe fruits.
Hope this helps!
A population of frogs with
slightly different coloring is an example of microevolution. Microevolution is
the changes in the gene pool of a population that can be measured and observed in
short periods of time within a population. Microevolution can take place in
several ways such as gene flow, genetic drift, mutation and selection.

The answer is D. The Protista have very little in common with each other besides being unicellular and Eukaryota.
Protista is one of kingdom that consist of any eukaryotic that could not classified as plant, animal or fungi. Since the classification itself based on exclusion, protist group has much less similarity than other group. All protist is unicellular and eukaryote but other than that, they will have many difference in other aspect.
