Fossil remains of Lustrosaurus (an extinct four-legged animal) have been discovered in India and
South Africa. When they were living, all the Lystrosaurus lived together on land, and they could not
swim. However, now there is an ocean between the Lystrosaurus fossils. What could explain how
these fossils got so far apart?

A. India and South Africa are parts of different plates. The plates slowly moved far apart as
soft, solid rock from underneath got added to the edges of the plates over millions of years.

B. India and South Africa are parts of different plates. The plates floated away from each other
across the ocean.

C. India and South Africa are parts of different plates. The plates slowly moved apart as new
plates from underneath got added between them over millions of years.

D. India and South Africa are parts of different plates. The plates were sometimes pushed far
apart by earthquakes, and soft, solid rock from underneath got added to the edges of the
plates.

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.
