Question 5

What is the dichotomous key

Answer 5

Is used to identify and classify living things.

Question 6

What is biogeography

Answer 6

An examine the disruption of organisms on earth

Question 7

What is comparative anatomy

Answer 7

Comparing the structure

Question 8

What is comparative embryology

Answer 8

Compare the embryonic development

Question 9

What is comparative physiology

Answer 9

Compare the internal functions

Question 10

What is comparative biochemistry

Answer 10

To compare the biological chemicals made by the organisms

Question 11

What are some homologous features

Answer 11

-Similar structures
-Each modified to suit a different function

Question 12

Analogous features

Answer 12

Similar in appearance and function
Completely different structurally
No common ancestor- superficially similar due to same environment pressures to adapt to

Question 13

Vestigial features

Answer 13

Rudimentary structures
Serve no useful function
Evidenced that they once served a function in ancient ancestor

Question 14

What is an acquired characteristic

Answer 14

Individuals lose characteristics they do not acquire and developed those which are useful

Question 15

What is heritable

Answer 15

Traits acquired or lost by a plant or animal through use or disuse will be passed on their offspring

Question 16

Who is Jean Baptiste Lamarck

Answer 16

He recognized that organisms have changed over time

Question 17

What is Lamarck theory

Answer 17

He believes if a parent does something it will get passed on to the offspring acquiring its characteristics

Question 18

Is lamarck theory true?

Answer 18

No they are false since organisms dont change their characteristics because they need or want it and characteristics acquired in life are not passed on

Question 19

What is Darwin Wallance theory of evolution

Answer 19

He proposed that a mechanism called natural selection to explain how evolution occurred

Question 20

Whats the 5 main idea of natural selection

Answer 20

1)overproduction
2)struggle for existence
3)variations
4)survival of the fittest
5)origin of new species by inheritance of successful variations

Question 21

Where do these adaptive genes come from

Answer 21

Mutations

Question 22

Where does genetic variation come from

Answer 22

Sexual reproduction

Question 23

What is a gene pool

Answer 23

All the genes in a certain population

Question 24

What is evolution

Answer 24

Is that change over many generations in a populations gene pool

Question 25

What is asexual reproduction

Answer 25

One parent divides to produce offspring- they are genetically identical to each other and the parent

Question 26

Sexual reproduction

Answer 26

Two parents contribute genetic material to the offspring- each offspring is unique genetically

Question 27

What is speciation

Answer 27

The formation of a new species

Question 28

What are species

Answer 28

Population of individuals that do not interbreed with other species (reproductively isolated)

Question 29

What is allopatric speciation

Answer 29

1)Physical barrier splits a population into two or more isolated groups 2) populations evolve independently (each adapt to their own environment)

Question 30

What is divergent evolution

Answer 30

Is then one ancestor population gets split up into diffrent environments and adapt and evolve to their diffrent environments making them more and more diffrent

Question 31

What is convergent evolution

Answer 31

different populations move into the same environment and over time each population evolves and adapts to the same environment make them more and more similar

Question 32

What are the two theories of evolution

Answer 32

Gradualism and punctuated equilibrium

Question 33

What is gradualism

Answer 33

Speciation occurs at a slow, steady pace and populations diverge gradually

Question 34

What is punctuated equilibrium

Answer 34

Periods where species evolve rapidly and followed by periods of little or no change

Question 35

What is macro evolution

Answer 35

Is an evolution above the species level and occurs over large periods of time
