The following diagram shows the branching tree diagram for some animals. A slanting line is shown. There are five lines drawn vertically on this line at equal intervals. Shark, Frog, Kangaroo, Lion and Chimpanzee are written on top of each vertical line in order from left to right. Common Ancestor is written on the left end of the line. There is a black circle between each pair of these vertical lines. The first black circle is before Shark and says Vertebrae. The second black circle is between Shark and Frog and says Lungs. The third black circle is between Frog and Kangaroo and says Mammary gland. The fourth black circle is between Kangaroo and Lion and says Placenta. The fifth black circle is between Lion and Chimpanzee and says Large brain. Which derived characteristic is shared by at least four organisms?

Large brain

Lungs

Mammary glands

Placenta

Alichen is an organism that structurally appears to be a single organism. but a lichen is actually two different organisms—a fungus and green algae—living together as one organism. the fungal partner derives its nutrition from the photosynthesizing algae. how does a lichen differ in its photosynthetic activity from elysia chlorotica, the sea slug that’s considered to be a photosynthesizing animal? a. in lichens, the fungi photosynthesize on their own, while elysia chlorotica forms a relationship with a photosynthesizing plant. b. in lichens, the relationship with the algae lasts throughout the life cycle, but in elysia chlorotica, the relationship occurs only during the immature juvenile stage of the slug’s life cycle. c. lichens can photosynthesize only because of the living algal partner, while elysia chlorotica incorporates chloroplasts from algae into its cells. d. in lichens, the association between the fungi and algae is permanent, while elysia chlorotica associates with a photosynthesizing organism only when it requires food.
