1.)  Birds have a single gland used for the preening of feathers called the ______.

2.)  The ______is the layer of skin derived from the ectoderm.

3.)  ______are types of hair used as sensors.

4.)  Mammals have four types of glands: , , , and ______.

5.)  The hypothalamus, master center of the system, produces hormones that stimulate the gland to release its hormones.

6.)  The are controlled by follicle stimulating hormone and luteinizing hormone. These glands also produce which is important for the preparation of labor and for cervix dilation.

7.)  The bird stomach is divided into 2 portions: the which produces the digestive juices and the that grinds the food by muscle action.

8.)  The “true stomach” in ruminants is known as the ______.

9.)  The rhythmic muscular contractions that push food through the digestive system are known as ______.

10.)  The or appendix is a pouch in the digestive tract wall that contains bacteria to aid in digestion. In some vertebrates, this structure is or has a reduced/absent function.

11.)  The is the largest gland in vertebrates. It filters blood and it also produces bile. Bile is stored in the .

12.)  The is the major water and salt balance organ in vertebrates. It is composed of millions of functional units called .

13.)  fish are fish that migrate between salt and fresh water. Salmon are ______, meaning they move from salt water to fresh water, while the Atlantic eel is the opposite, known as .

14.)  Neurons can be divided into 3 classes: , , and ______.

15.)  synapses occur when an action potential arrives at the synapse. This opens the calcium ion channels that cause the ions to enter the cell. This triggers the release of into the synaptic cleft. These then bind to the ______, exciting it. The postsynaptic is propagated. The neurotransmitter is then degraded, returned, and stored.

16.)  The subdivision of the nervous system that contains the brain and spinal cord is known as the ______.

17.)  In vertebrates, ______is more sensitive than ______.

18.)  ______are used by fish to detect wave vibrations and currents in the water.

19.)  In vertebrate, the organ of balance is the , and the organ of hearing is the ______.

20.)  In the eye, the provides achromatic vision that is used for vision in dim light. The provide chromatic vision that is useful during abundant light.

21.)  vision produces a broad overlap of fields of vision that allows for more depth perception. On the other hand, vision provides a wide field of vision but with less depth perception.

22.)  ______is asexual reproduction where the egg develops into a new individual without fertilization.

23.)  When the temperature of the environment determines the sex of the offspring, it is known as ______.

24.)  species produce many offspring that have low survival and have little parental care. species produce a few offspring that have high survival with a great deal of parental care.

25.)  In , there is one male and one female pair bond that lasts for at least the breeding season. is where there are multiple pair bonds that occur at one time or sequentially. is where there are no pair bonds.

26.)  The turbulence that results from a fish moving and displacing water is called ______. The friction between the body of the fish and water is ______.

27.)  ______is the tendency to move side to side. ______is an up-and-down movement. ______is the tendency to go right or left.

28.)  The type of flight that requires height or speed to get an organism airborne, is called . flight requires muscular activity to take off and to stay airborne.

29.)  The shape of the wing that is teardrop shaped and helps promote lift is called ______.

30.)  The flight involves 3 specific steps or motions called , , and ______.

31.)  ______soaring is typical of seabirds using strong winds on the ocean.

32.)  Runners tend to have a Lo/Li ratio whereas diggers tend to have a _____ Lo/Li ratio.

33.)  Geckos are a species that use specialized ______on their toes for climbing.

34.)  A form of bipedal locomotion characterized by well-developed hind limbs and a strong pelvic girdle is known as ______

35.)  A is a sequence of behaviors that once initiated is unchangeable and usually carried out to completion.

36.)  ______causes of behavior tend to be genetic, while ______causes of behavior are why the behavior developed.

37.)  ______is a behavior that reduces the fitness of the individual while increasing the fitness of other individuals, while ______behaviors are highly ritualized and symbolic.

38.)  When a local species goes extinct as a result of competition, this is an example of ______.

39.)  ______is when one member of the association benefits and the other is neither helped nor harmed.
