Make an observation, create a hypothesis, test the hypothesis, draw conclusions and refine the hypothesis.

Answer:

Squirrel: Digestive, Circulatory, Muscular, and Nervous systems.

Soccer: Skeletal/muscular, circulatory, respiratory, and nervous systems.

Explanation:

The body systems are skeletal, muscular, digestive, respiratory, nervous, and circulatory. All of them interact and work together as a whole to the proper individual development and performance.

We might say that in both cases, all the systems are interacting. However, we can mention four of them for each situation.

The squirrel

This animal seems to be feeding on the top of a tree, sitting on a branch where it keeps its balance not to fall.

  1. The digestive system is working to break food into smaller pieces that are more suitable to swallow and absorb the available nutrients.
  2. The circulatory system takes those nutrients and transports them together with the oxygen to different cells in the organisms where they are needed.
  3. The muscular system makes it possible to keep the animal´s balance in the branch and not fall.
  4. The nervous system controls everything in the organism. The nervous system controls all the body activities. It is in charge of keeping equilibrium while eating and being alert, among many other functions.

The soccer player

This person is about to hit the ball to make a goal. He seems to be coordinating his arms and legs move to make it possible.

  1. The muscular and skeletal systems are working together to provide support to the body and strength. They allow the movement of the whole body to make the goal.
  2. The respiratory system is also involved in this person´s performance while he is running. He needs to keep constant respiration to inhale enough oxygen needed while running and exhaling waste gases.
  3. The circulatory system transports the oxygen to different cells in the organisms where they are used according to their needs, especially the muscle cells. This system also takes away the wastes substances.
  4. The nervous system controls all the body activities. It is in charge of keeping equilibrium and coordinated moves while running, being alert on other players and focused on the ball, controlling the player´s thoughts and strategies during the game, among many other functions.

Indicate which pattern of evolution is shown by the many species of finches on the Galápagos Islands.
-Dominant- [34]
Answer;
Adaptive radiation;
The pattern of evolution that is shown by many species of finches on the Galapagos Islands is Adaptive radiation. 

Explanation; 
Adaptive radiation is a pattern of evolution in which a single lineage undergoes multiple speciation events to fill divergent ecological niches. The result is a cluster of phenotypically distinct related species.
A few million years ago, one species of finch migrated to the rocky Galapagos from mainland of Central or south America. From this one migrant species would come many species;-at least 13 species of finch, which exploit different niches, evolving from a single ancestor.
