The most likely explanation for why toothed whales have a blowhole is

Scientists studying a group of related bird species on an island archipelago discover that these species are always more closely related to each other within an island than they are between any two islands. The most likely explanation for this result is that

What do figures X and Y in the graphic illustrate?

What is the main structure that differentiates between ρρ-dependent and ρρ-independent termination in prokaryotes?

A cell line called HeLa cells has been used in cell research for over 70 years. These cells were taken from a patient with cervical cancer. Why have they survived so long?

The disease, sickle-cell anemia is common in malaria-infested areas because individuals that are heterozygous for the gene (AS) have enhanced resistance to malaria over normal individuals (AA). Individuals with severe sickle-cell anemia (SS) usually die before reproduction. If this population moves to an area without malaria, what will happen to the allele frequency of the A allele over time?

You are working in a molecular biology lab and, unbeknownst to you, your lab partner left the foreign genomic DNA you are planning to clone on the lab bench overnight instead of storing it in the freezer. As a result, it was degraded by nucleases, but still used in the experiment. The plasmid, on the other hand, is fine. What results would you expect from your molecular cloning experiment?
