The two major surviving clades of diapsids include modern animals like snakes, lizards, crocodiles, and birds

A clade is a branch in a cladogram that has a single common ancestor with all of its offspring. An evolutionary tree that depicts the relationships between species' ancestors is called a cladogram. In the past, cladograms were created using similarities among species' phenotypic or physical characteristics.

All hominoids, including humans, chimpanzees, gorillas, orangutans, and gibbons, are members of this group. The Hominoid clade is a subgroup of the Anthropoids, a broader clade that includes Old World and New World monkeys. The use of a phylogenetic tree makes clade identification simple. Just visualize pruning even one branch from the tree.

joja [24]

Answer:

Groups 4 to 7 are most likely to be undergoing the mitotic phase of the cell cycle.

Explanation:

Since the four proteins used p16,  p18,  p21, and  p27 are inhibitors of cyclin-dependent kinases (CDK), their absence indicates that the cell is undergoing mitosis - the cell cycle is regulated by CDKs. In the absence of these inhibitors, the cell cycle moves on forward. Because the bar for DNA replication is longer in the case for groups 4 to 7, it is indicative of the fact that these cells have gone through the mitotic phase.

Hope that answers the question, have a great day!
