Evolution and Adaptation
1- Explain adaptive radiation and how the different paper forms made by “finches” helped or hurt that particular finch species.

2- With the" prey" survival data you collect, graph survivorship over time by each species.
3- Explain how behavioral adaptations may lead to genetic changes in a population.
There are several factors that cause different such as: geographical isolation, climate change, and adaption to survive against competitors, predators, flexibility in the early learning of feeding skills that lead to genetic changes in a population.
4- A species that has a behavioral adaptation that may allow its predator not to be able to eat it or find it. Explain what this behavioral adaption is.
Chameleon is small lizard best known for its physical adaptation.
Color changes: Chameleons are capable of changing color. These color changes assist the reptile to camouflage itself in the presence of potential predators.
Tongue: The ability to shoot its tongue over such a distance and with amazing accuracy allows the chameleon to reach food not in its immediate vicinity.
5- A species that has a physical characteristic that allows it to survive in cold weather.
Arctic Hare lives throughout the tundra of Canada from Newfoundland to Nunavut and the Northwest Territories.
Adaptation: The claws on the front feet are long and their strong claws are used for digging in hard-packed snow. The arctic hare’s coat grows longer and thicker for the winter. They have a short thick undercoat protected by a longer top coat. The white fur makes the hare difficult to spot in the snow.
6- An example of mutualism in nature. Explain what mutualism is this case
Lichens are a mutualism formed between fungi and various groups of algae.
Mutualism: The algae provide food for algae by doing photosynthesis and the fungi helps out by forming a protective envelope for the algae preventing the algae from drying out.

7- An example of commensalism in the nature. Explain how your picture represents commensalism.
The Orchids grow on branches of trees. Orchids belong to a family of flowering plants that form a commensal relationship with the trees.
Commensalism: They form their base of attachment on the branches of trees, and benefit by getting adequate sunlight and nutrition that flows down the branches. The orchids do not grow to a large size, and thus the host tree is not harmed in any way.
9- An example of mimicry in nature. Explain what the mimicry is this case.
Fork-Tailed Drongo also called the Common Drongo, African Drongo, or Savanna Drongo, is a drongo, a type of small passerine bird of the Old World tropics.
Mimicry: These particular birds mimic the sounds of meerkats to steal their food. They can use the meerkats own calling sounds to make them run away and when they finally click on that they’re being fooled. The drongo then mimics another species (a predator to the meerkats) to make them run away again, to steal their food again.
10- One species of plant from Haiti that has an adaptation that let it survive. Explain.
Bayahondes grow in rigid soil, dry and hot region of Haiti.
Adaptation: This species of tree develop big thorn from their buttress part to the top and also the leaves in order to prevent to be eaten by animal.
