New genes can evolve from all of the following except a. gene duplication from unequal crossing over. b. combining parts of two or more genes. c. exon shuffling. d. gene duplication from crossing over. e. gene duplication from replicating transposable elements.

The answer is (E) Gene duplication from replicating transposable elements.

Explanation:

Gene duplication from crossing over or unequal crossing over can leads to appearance of new DNA sequences. Then, the new sequences create new genes. It can also find in many text books as a chromosome mutation.

From C. exon shuffling, it is also a way to make new genes in which different exons from different genes can be bought together, or the same exon is duplicated. Thus, these causes change the DNA sequences.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
