You are a scientist and you injected microscopic fluorescent beads into a subject's vasculature. These beads are roughly the size of blood cells. After allowing enough time for the beads to fully circulate, you evaluate the tissue fluorescence just outside the various types of capillaries. Which of the following is the most reasonable prediction for this study?

A..)You predict to find a high amount of fluorescence in the tissues surrounding the discontinuous capillaries
B.)You predict that the beads will actually lodge in the sinusoids associated with the discontinuous capillaries and be unable to pass through them.
C.)You predict to find little to no fluorescence in the tissues surrounding the discontinuous capillaries.
D.)You predict that the highest amount of interstitial fluorescence will be found in skeletal muscle tissue.

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.
