Biology evolution

Question 1

Directional selection

Answer 1

one side wins( curve shifts left or right)

Question 2

Stabilizing selection

Answer 2

(middle gets taller/narrower) middle wins

Question 3

Diversifying/disruptive selection

Answer 3

(two peaks form) Both extremes win/ middle doesn’t win

Question 4

percent change equation

Answer 4

(final-initial)/initialx100

Question 5

In an evolutionary sense, an individual organism that has high fitness if it

Answer 5

reproduces more successfully than other individuals.

Question 6

Evolution

Answer 6

change over time

Question 7

Natural selection

Answer 7

The process where organisms better adapted to their environment tend to survive and produce more offspring

Question 8

5 main parts of Charles Darwin’s theory

Answer 8

variation, overproduction, competition for resources, survival of the fittest, reproduction

Question 9

Fossil record

Answer 9

Fossil records provide evidence of the history of life on Earth.

Question 10

Molecular biology

Answer 10

We can compare differences in DNA or amino acid

Question 11

Comparative anatomy homologous

Answer 11

same structure, different functions.

Question 12

Pinky finger

Answer 12

population shrinks/genetic drifts

Question 13

Ring finger

Answer 13

non-random mating/sexual selection

Question 14

middle finger

Answer 14

mutations

Question 15

pointer finger

Answer 15

movement(immigrant/emigrant)

Question 16

thumb

Answer 16

natural selection

Question 17

5 Conditions of Hardy- Weinberg Equilibrium

Answer 17

population must be large, so no genetic drift; random mating must occur; no mutations; no gene flow; no selection can occur.

Question 18

comparative anatomy analogous

Answer 18

same function/different structures

Question 19

Comparative Anatomy Vestigial Structures

Answer 19

features with no useful functions, but did in ancestors
