Animal Form and Function

The following all are essential to animals survival EXCEPT

• Energy Allocation/Utilization

• mechanism to move

• Ability to exchange materials with the environment

• Coordination and control to maintain Homeostasis

• Thermoregulation

What is the correct hierarchical organization of animals?

• cells-->tissues-->biological molecules-->organelles

• biological molecules-->cells-->organelles-->tissues

Hormones:

• are slow acting

• long lasting

• unable to coordinate the body

• a and b only

a regulator

• maintains internal environment when external is changing

• allows internal conditions to vary based on external enviorment

• can disrupt homeostasis

• none of these

an example of homeostasis in the human body is

• sexual reporduction

• glucose concentration in the blood

• size of the animal

negative feedback is when

• the product amplifies the reaction

• the stimulus is not strong enough to produce a reaction

• homeostasis is not maintained

• when the product inhibits the reaction

positive feedback is when

• homeostasis is maintained

• the product amplifies the reaction

• the product inhibits the reaction

• is bad for the organism

an example of negative feedback is

• child birth

• eating a burger

• thermoregulation
