What does DNA sequencing suggest about the relationship between the nuclear and organellar genomes?
A) The same subset of mitochondrial genes has moved to the nuclear genome in all species.
B) Mitochondrial genes that are found in the nuclear genome do not have introns, suggesting that movement occurred via an RNA intermediate.
C) The mitochondrial and nuclear genomes are entirely independent of each other.
D) Some cells have two types of mitochondria that have different genome sequences.
E) Some proteins found in mitochondria are imported from the cytoplasm.
B) Mitochondrial genes that are found in the nuclear genome do not have introns, suggesting that movement occurred via an RNA intermediate.

Based on the literature, you hypothesize that students in traditional biology lectures will have the same grades as students in online biology lectures. You decide to test your hypothesis by comparing grades of students in traditional and online biology lectures over a semester. As a result of the experiment, you observe that the grades in the traditional lectures and the grades in the online lectures are not significantly different. What do these observations allow you to do?
A. accept the hypothesis without further question B. reject the null hypotheses C. develop a scientific theory D. reject the hypothesis
