A student is building a tree using the cladistic method of tree construction. They have identified an appropriate outgroup and characters to use to determine the relationships between the species. Their data table is shown below. character outgroup species A species B species C species D species E short antennae 0 1 1 1 1 0 wing spots 0 1 1 1 1 1 protrusion on back of head 0 1 0 0 0 1 jagged wing margins 0 1 0 0 1 0 elongated mouth parts 0 0 0 0 1 0 thickened upper wings 0 1 0 1 1 0 yellow wing margin 0 0 0 0 1 0 Which two species are the most closely related to each other, and should be placed as sister species in the tree?

Above is a phylogenetic tree of the major animal phyla. You don’t need to do anything with it, but you can refer to it to remind yourself of the phyla and help you answer this question. Below are descriptions of several animals. Based on the features given, identify which phylum the animal belongs to.

The diagram above shows several processes involved in replicating a reverse-transcribing RNA virus from its genetic material.  Producing dsDNA (double-stranded DNA) from ssRNA requires . Producing mRNA from dsDNA occurs via the process of . In a bacterial cell, proteins are synthesized using information in mRNA by the .
