When you study about the cladogram of animals you can determine the similarities and difference of each animals in the cladogram. The lizard do share with the chimp or chimpanzee is only lungs so the answer is A. But not only the lizards and chimp do have the lungs but also salamander, pigeon and mouse.
A cladogram is a diagram which is used to depict phylogenetic relationships between organisms belonging to same or different species. A clade can be defined as a group of organism exhibiting common traits similar to the ancestor organism. A cladogram indicates a relationship between organisms with their ancestors. Here, in the given cladogram the characteristics which are common in lizards and chimpanzee are lungs and claws or nails. As, lizard belongs to a group of reptiles and chimpanzee belongs to a group of mammals. Lungs are present in them to support respiration. Claws or nails are present to run and hold surfaces or substrates. For example, climbing on a wall or tree requires claws or nails.
Let G be the dominant allele for stem color and g be the recessive allele for stem color. Let P be the dominant allele for leave shape and p be the recessive allele for leave shape.
Sandstone contains fossils of creatures such as trilobites, brachiopods, crustaceans, bryozoans and plants. Remains of land animals like mastodons and dinosaurs are much more likely to be found in sandstone.
