Question 1

What is the study of animal behavior called?

Answer 1

Ethology

Question 2

What is Ethology concerned with in animals?

Answer 2

With everything that the animals do and how they do it, including actions like movement, sound production, and learning.

Question 3

how many components can behavior broken into?

Answer 3

3 major components

Question 4

what are the three major components of behavior?

Answer 4

Stimuli, Neural integration, response

Question 5

Stimuli

Answer 5

That initiate the behavior. Usually these stimuli are detected by sensory receptors such as those for sight, touch, sound, temperature, or chemicals. The stimuli may originate from sources external to the organism or from internal conditions such as hunger or thirst.

Question 6

Neural integration

Answer 6

The stimuli are evaluated by the central nervous system, which then determines the response. the response is one that has evolved through natural selection, and therefore, is adaptive and usually (but not always) favor the survival of the animal.

Question 7

Response

Answer 7

usually a pattern of nerve impulses directed by the central nervous system and the sequence of muscle contractions that they initiate.

Question 8

Innate

Answer 8

Instinctive behaviors, being those are carried out regardless of prior experiences.

Question 9

Orientation behaviors

Answer 9

those that place the animal in its most favorable environment.

Question 10

taxis

Answer 10

If an animal moves either toward or away from a stimulus.

Question 11

Kinesis

Answer 11

If an animal’s movement is completely random and does not result in directed movement with respect to a stimulus.

Question 12

If an organism responds to an area of higher temperature by moving away from it.

Answer 12

Taxis ( negative thermotaxis)

Question 13

if the organism’s response is to move in all directions in a totally random manner.

Answer 13

Kinesis

Question 14

What other stimuli can affect behavior?

Answer 14

exposure to light and humid environment.

Question 15

Brine shrimp

Answer 15

phylum Arthropoda and belong to the class Branchiopoda, the family Artemiidae and genus Artemia.

Question 16

Which same phylum does Artemia belongs to?

Answer 16

terrestrial isopods

Question 17

What do terrestrial phylum includes

Answer 17

pill bugs

Question 18

Artemia are also known as?

Answer 18

colloquially as sea monkeys

Question 19

What do Artemia produce?

Answer 19

dormant eggs called cysts, which can lay dormant for long periods and hatched on demand, ; leading to their extensive use in aquaculture as live feed for fish and crustaceans.

Question 20

What has two widely separated compound eyes mounted on short but flexible stalks?

Answer 20

Artemia

Question 21

What sensing organs does Artemia have?

Answer 21

Light

Question 22

moving away

Answer 22

is negative taxis

Question 23

moving toward

Answer 23

postive taxis

Question 24

what are planarians

Answer 24

flatworms of the phylum platyhelmintes and belong to the class turbellaria, the family planriidae and genus planaria.

Question 25

where do planarians live?

Answer 25

in marine and freshwater environment along with some terrestrial members that live beneath rotting logs.

Question 26

which animals first develop signal transference between nerve, via the chemical messenger acetylcholine

Answer 26

flatworm

Question 27

What do planaria lack ?

Answer 27

a cardiovascular system but have a highly branched digestive tract.

Question 28

In planaria how are nutrients delivered to the body?

Answer 28

vis process called diffusion.

Question 29

what is the t-test

Answer 29

a statistical test that compares the mean and standard deviation of two sets of data to show whether there is a significant difference between them.

Question 30

What is a paired t- test used for?

Answer 30

to compare two populations means where you have two samples in which observations in one sample can be paired with observations in the other. The paired t-test is a commonly used to compare before and after observations on the same subjects.
