Kierra is trying to decide which brand of lettuce seeds she would like to use in her garden this summer. After researching, she picked the two best-known brands to test. She decides to test them by planting one of each seed in a small space in her yard; her observations will be recorded so she can compare.
Which is the best example of a negative impact of planting only one seed from each brand?
A) She might confuse the plants if there is only one of each, resulting in incorrect observations.
B) She will not be able to collect enough measurements to create graphs to compare her data properly.
C) Sometimes seeds get incorrectly packaged in factories; one of the seeds she plants may not truly be a lettuce seed. She would not know this until after her study.
D) The one seed she chooses from either packet may be defective and grow improperly. She would only have results from a bad seed for that brand and not have true data from typical seeds of that brand.

The evolution of molecular biology has made possible to establish a new classification of all organisms according to their DNA, and it's called phylogenetic classification. This classification group living beings according to their kinship it is established according to anatomical, and especially genetic, based on the similarity of genes between species.

This made it possible to discover kinship ties between species of which there is no suspicion of any morphological link between them, something which the old classification (the traditional classification) was incapable of doing (and this proves the importance of the DNA and genes in organisms classification.
