Write a short scientific summary comprising 150 words of your findings from this investigation. Be sure to answer the questions below as well as including your own data and reflections. How many times did your heartbeat in one minute when you took your own pulse?

How many times did your friend or parent's heartbeat in one minute?

If you took the pulse of someone who was a different size or age than you, did you notice a difference in heart rates?

Body size, age, and fitness level are factors in heart rate. Why is this?

When you counted heartbeats over periods of ten, fifteen, and sixty seconds, did you notice differences in the final heart rates? If so, was the difference significant?

Why is the ten- or fifteen-second method of taking a pulseless accurate than counting the beats in an entire minute?

After you ran in place, what happened to your heart rates? Why do you think this took place?

What did you find out from this experiment? Be thoughtful in your answer.

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.
