Lab 6


  
EVOLUTION AND ADAPTATION

  • Explain adaptive radiation and how the different paper forms made by the "finches" helped or hurt that particular "finch species".
Adaptive radiation is a process in which organisms diversify rapidly into a multitude of new   forms. One of the first things Charles Darwin noticed is the variety of finches that existed on   each of the islands. All in all, there were many different species of finch which differed in beak shape and overall size. 

Darwin's Finches
Adaptive Radiation in Darwin's Finches
These finches, better known as 'Darwin's Finches' illustrated adaptive radiation. This is where species all deriving from a common ancestor have over time successfully adapted to their environment via natural selection.

  • Fill out the following table with your groups data ata the end of the natural selection experiment.

  • With the "prey" survival data you collect, graph survivorship over time for each "species". There will be one graph for each candy type. Make sure you give your graph titles and label units and axes.
  •  Explain how behavioral adaptations may lead to genetic changes in a population.
Depending on the ecosystem a individual live. In the last class what I learned is that in some species the female attract the male with her beautiful physical characteristic, so the male can be form another species, and they adapt to each other. One example of adaptation is climate change and it affect population of organisms has to adapt over the time and evolution is start taking place. 
 

  • 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
Available from.






Chameleon is small lizard best known for  its physical adaptation, its tongue has the ability to shoot in such a large distance and allows to reach food that is not belong to it.The chameleons can change color to defend its-self for predators.

 






  • A species that has a physical characteristic that allows it to survive in cold weather.
Available from.
Polar bear can can live in several cold places, they can swim in any type of condition its stamina is very high allow to swim many hours and cross long distances. Through its life have to adapt to any condition.












  • An example of mutualism in nature. Explain what mutualism is this case 

The algae provide water to the tree and the tree provides food for the algae by photosynthesis, so both are doing symbiosis because both of them get benefits.










  • An example of commensalism in the nature. Explain how your picture represents commensalism.

Available from.
A butterfly is taking honey from this flower, so we can see here is commensalism because one gets benefit and the other one no, but either hurt the flower. 












    • An example of mimicry in nature. Explain what the mimicry is this case.

    Ant Myrmecomorphy its behavior is seen as a predator but in this case isn't because the only that ants are looking for is to survivey. 








    • One species of plant from Guatemala that has an adaptation that let it survive. Explain. 

    Pure Sativa grows indoor and outdoor without any problem, any latitude. This plant flowering in November. Mostly people ca located it in the jungle of Tikal Peten Guatemala.

    1. Hi Ingrid,
      Nice work on your lab in general. One questions 1 and 2 the answers are a copy paste from another website. I was hoping to read your work. Your grade is 8/10.
      Regards,
      Shadia
