High levels of fotness

Question 16

Dwm stands for

Answer 16

Descent with modification

Question 17

Individuals with terrible and weak characteristics will have

Answer 17

Will die or leave very few offspring (Low fitness levels)

Question 18

Homolgous structures means

Answer 18

Same structures and same functions

And are from close relatives

Question 19

Analogous structures is

Answer 19

When they have similar structures as well but the have distant relatives and they have similar finction BUT they come from a different origin not same origin like homologous

Question 20

What does vestigial structures mean and what is an exampel

Answer 20

It means that they are structures that no longer have a function in modern day organisms . (Such as the appendix)

Question 21

Embryology

Answer 21

Study of developing embryos that show similarities between organisms. The clser they are rekated the more similar they looked like before further development into an adult

Question 22

Molecular biology

Answer 22

Study of dna and its similarities amongst organisms.

The more related the more amino acids or dna sequences in common

Question 23

What is divergent evolution

Answer 23

Organisms move to other places and evolved traits that suited them for a particular enviornment

Question 24

What is convergent evolution

Answer 24

Even if theye evolved from a different common ancestor if they are living in the sane enviornment they will have similar traits

Question 25

Dna sequences provides a what evidence of evolution

Answer 25

It provides a strong evidence of evolution

Question 26

Transitional forma

Answer 26

Provide evidence of intermediate forms that link one group of organisms to another

Question 27

Embryos look much more similar when | Many different vertebrae

Answer 27

When they are in the early stages they look similar

Question 28

Comparitive anatomy includes

Answer 28

Homologous and analogous structures

Question 29

Biogeogrpahy is

Answer 29

The study of how and why plants and animals live where they do

Question 30

Which process is the strongest evidence for common ancestry

Answer 30

dna sequence

Question 31

Bats and birds are considered

Answer 31

Homologous structures because. Have the smae function in close relatives

Question 32

Tiktaalik is a what form and why

Answer 32

It is a transitional form because they have the characteristics of both a fish and a tetrapod (four limbs)
