Warm Up-Honors/Pre AP Bio Monday, February 13 Homework Due Today: No Homework due today A small, short-furred, gray animal called a divo lived on an island. This island is the only place on Earth where divos live. The island habitat is warm and provides plenty of the divos’ only food- tree ants. The divos live high in the treetops, hidden from predators. One year the habitat experienced a drastic change that lasted most of the year. It became very cold and even snowed. All of the ants died. The trees lost their leaves, but plenty of seeds and dried leaves were on the ground. What do you think happened to the divos? A. The divos’ fur grew longer and thicker B. The divos switched to eating seeds C. The divos dug holes to live under the leaves or beneath rocks D. The divos hibernated through the cold period until the habitat was warm again E. The divos died Explain WHY! Homework: * Amazing, Adorable, Adaptations due Wednesday/Thursday

Warm Up- Honors/Pre-AP Bio Tuesday, February 14 Homework Due Today: No Homework today The Esposito family went hiking on a tall mountain. Mrs. Esposito picked up a shell fossil on the top of the mountain. The fossil was once a shelled organism that lived in the ocean. The family had different ideas about how the fossil ended up there. This is what they thought: Mrs. Esposito: A bird picked up the organism and dropped the shell as it flew over the mountain. Mr. Esposito: Water, ice, or wind eventually carried the fossil to the top of the mountain. Rosa: A mountain formed in an area that was once covered by ocean Sofia: The fossil flowed out of a volcano that rose up from the ocean floor. Who do you agree with? Why?
