who were the greats

A

lorenz, tinbergen, and von frisch

28
Q

ethograms are…

A

is a description an documentation of the behavioral patterns under study, a behavioral inventory-tool to study behavior

29
Q

kin selection is…

A

proposed by hamilton and is known to be a form of natural selection in which individuals can increase their fitness by helping close relatives, because close relatives share the helper’s genes

30

altruism is…

A

(kin selection is used to describe altruism) individual selection can explain cooperation through inclusive fitness

31
Q

Overall increase in fitness and animal gets by helping itself and others

inclusive fitness

true

33
Q

What is the change in allele frequencies in a population over time

evolution

34

Strange act where an animal will put itself in harm’s way in order to help others

A

altruism

36

What consists of the neurons and neuroglia that attach to the brain and spinal cord

A

CNS

37
Q

What is more abundant that neurons in the body

A

neuroglia

38
Q

What is the ways bees communicate where food is outside of the hive

A

waggle dance

39
Q

What nervous system contains nerves that connect to the CNS and muscles and organs

A

PNS

40
Q

Cells that monitor stimuli during sensation are called

A

receptors

41
Q

What are the functional signal conducting cells:

A

neurons

42
Q

supporting cells

A

neuroglia

43
Q

What Is a type of neuroglia that act as K and Na buffers

A

astrocytes

44
Q

Type of neuroglia that acts as a macrophage of the CNS:

A

microglia

45
Q

What types of neuroglia in the PNS has no known function

A

satellite cells

46
Q

Input region of a neuron:

A

dendrites or soma

47
Q

Define lateralization in terms of the brain and 2 hemispheres

A

Left side of the brain controls right side of body and visa versa as well as their specific functions that are different. That is not 100% so some parts of the right brain also works when moving the right side of the body because if one side of the brain got hurt the other side can compensate. Lateralization balances out the brain

48
Q

Three kinds of neurons that connect to CNS

A

Sensory, motor, interneuron

49
Q

Sympathetic and parasympathetic are a part of the autonomic which is part of the

A

peripheral
