1. While in the Galápagos Islands, Darwin observed two tortoises: the domed tortoise found on Isabela
Island (shown at top) and the saddleback tortoise
found on Hood Island (shown at bottom). Using the
draw pad tool, outline in red the part of the shell
near the legs and neck of each tortoise to show
how they are different.
Which island is more likely to have a habitat with
low-lying food such as grass and moss? Provide
evidence from your drawing to support your
answer.

Drag each tile to the correct box. the body monitors the levels of oxygen in the blood to regulate breathing. isabel is running in a marathon and is near the finish line. she feels out of breath. how will her nervous system work to generate a reaction? arrange the tiles in chronological order. isabel's breathing rate increases. sensory receptors in the arteries detect low oxygen levels. the brain sends signals through motor neurons. sensory neurons generate an impulse. the central nervous system relays an impulse to certain brain regions.

Consider the venn diagram of plant reproduction. where in this image, areas a - d, would you insert the picture of the orange lily?
