Xylem is the answer......
I think the correct answer from the choices listed above is option C. The slowest type of mass movement, which involves the lifting and contracting of soil particles over time, is called creep. It is a <span>slow downslope </span>movement<span> of particles that occurs on every slope covered with loose, weathered material. Hope this answers the question.</span>
Answer:
D) choose the tree that represents the fewest evolutionary changes, either in DNA sequences or morphology.
Explanation:
Parsimony is a concept applied while constructing a phylogenetic tree. According to it the best tree is constructed by fewest evolutionary changes, either in DNA sequence or morphology. Complicated changes should be present as less as possible in a tree.
For example, suppose vertebrate relationship can be explained using two trees. Tree A has six evolutionary changes and evolution of bony skeleton occurs once. Tree B has seven evolutionary changes and evolution of bony skeleton occurs twice at different spots. Tree A will be preferred because it explains the vertebrate relationship in a less complicated way than Tree B.
