Activity 4 Directions: Perform the activity.
Materials:
Five flowers such as Gumamela, Santan, Yellow Bell Rose and ku-
mentang (or any available flowers, as much as possible there is
gumamela)
Procedure:
A. Carefully remove the sepals of the gumamela.
B. Open the flower and try to identify the parts.
C. Draw the respective parts of the gumamela flower on your
notebook in science.
D. Do the same with the other flowers.
E. Compare the gumamela with the other flowers.

The tasmanian devil, a marsupial carnivore, is facing extinction due to devil facial tumor disease (dftd) which causes bulging cancerous lumps and lesions to erupt around the face and neck — often causing enough deformation to make seeing or eating difficult. dftd has evolved into a contagious cancer, a trait that is unique among cancers. devil mating behavior involves biting around the head and neck, allowing cells from one individual — especially cells from the crumbly dftd tumors — to be transferred to the wounds or face of a new individual. this marsupial was once found across australia, but sea levels rose, isolating the tasmanian population, while the australian population went extinct. what would be an outcome of genetic isolation that is likely to have impacted the spread of dftd? a) reduced territory puts diseased individuals in greater contact with non-diseased ones. b) inbreeding results in less variation in facial features so the cancer is generally fatal. c) genetic isolation has made it difficult for scientists to develop a vaccine against dftd. d) the lack of genetic variation in the immune system of tasmanian devils minimizes resistance to the disease.
