Answer 10

Continuous - differences with a range of forms (hair color, eye color, height, etc.)
Discrete - differences that are either/or
(Roll tongue, hitch-hiker thumb)

Question 11

Inheritable v Heritable traits

Answer 11

Inheritable - traits that are not passed down in generations (dyed hair, muscles)

Answer 12

Binary fission
Budding
Spore
Vegetative

Question 13

Binary fission and A/E

Answer 13

a cell splits exactly in 2 producing 2 identical cells (single celled organism)
A - rapid population

Question 14

Budding and A/E

Answer 14

Parent produces small version of itself attached to itself. (Yeast, coral)
A - parent supports next generation so it lasts

Question 15

Spore and A/E

Answer 15

Spores created similar to seeds and then gets spread (mushrooms make ‘dust’)

Answer 25

when pollen is carried to stigma from another plant

Question 26

Cross Fertilization

Answer 26

When the grain of the pollen produces a tube that grows down the style into the ovary
