While an organism is developing, a process called "apoptosis", or programmed cell death, leads to past on they selfs of certain cells. An example is in the tail of tadpoles. Once a tadpole is mature enough to turn into a frog, the tail cells receive a "death signal" chemical, and the cell responds by shrinking, breaking up the nucleus, and then being completely destroyed by another frog cell. The chemicals that were within the tail cell are often recycled, and used to build new cells in the main body of the frog. During apoptosis, which cellular organelle does the work of breaking up the nucleus and causing the cell to die? A) ribosome

B) Lysosome

C) mitochondrion

D) Golgi apparatus

List two new traits (structural or behavioral) that each new species of rat might demonstrate as it adapts to the conditions on two of the four islands. choose only two islands that are described in the lesson. record the island latter and the major habitat feature of the island. then list two new traits each rat subspecies might demonstrate in order to survive the habitat on that island. note: new traits should be unique to that island and be in response to that island’s habitat feature. i cannot remember islands that were names in the lesson so only answer if you have done the lesson (5.13 life science 7b) choose 2 of the islands and describe a structural and a behavioral trait for a rat on each island so 4 total answers, 2 different structurals and 2 different behaviorals, one for each rat for each island
