What is NOT a property of water that helps make water essential for life on Earth? Water freezes into ice in its solid form, which floats on its liquid form insulating rivers
and lakes during cold weather.
Water absorbs heat during evaporation, a property which organisms can use to cool
themselves.
Water is able to absorb large amounts of heat which allows large bodies of water to
stabilize air and land temperatures.
Water is able to dissolve nonpolar substances such as oil, which helps it keep
substances from crossing into and out of the cell.

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.
