presence of the placenta (mammals)

Explanation:

Cat and dogs are two species that belong to the group of placental mammals (class Mammalia). Some phenotypic traits that are exclusive of mammal species include, among others, mammary glands, presence of hair or fur, sweat glands, specialized teeth, etc. A phylogenetic tree is a representation of the evolutionary relationships among different groups/taxa. Moreover, cats and dogs represent two different species of placental mammals, which are characterized by the presence of the placenta (an organ that facilitates the exchange of nutrients during gestation). In this case, the remaining two branches in the phylogenetic tree (branches from left to right) separate from more closely related to less closely related taxa that diverged from the same ancestral node.

interphase   is the cell cycle stage in which the cell acquires nutrients, creates and uses proteins and other molecules and starts the process of cell division by replicating the dna. it is the longest stage in the eukaryote cell cycle.

the following   can go wrong during interphase:   a base pair could be mismatched during the duplication process causing a mutation.   correct answer: c
