Answer 6

Chitin

Question 7

How do Fungi eat food

Answer 7

Extra cellular absorption

Question 8

Prokaryotes were separated bacteria and Archean based on

Answer 8

Biochemical differences

Question 9

Species name

Answer 9

Genus “made up”

Question 10

Why is present day classification not perfect

Answer 10

Protists are so diverse
Characterization of bacterial species is complicated because of horizontal gene transfer in bacteria
Virus are not included (because they can’t reproduce)

Question 11

Horizontal gene transfer

Answer 11

The movement of gene transfer between organisms (not vertical reproduction)

Question 12

Where do Archaea live

Answer 12

In extreme environments

Answer 13

Bacteria

Behavior
Molecular(DNA, RNA protein)

Answer 17

Refers to any one of many different types of organisms too small to see without magnification

Question 18

Answer 18

Microbes

Question 19

Ratio for microbial to human cells

Answer 19

1:13:1

Question 20

What does bacteria do?

Answer 20

Maintain weight
Improve immunity
Improve baby’s health (starts at birth)


Question 21

Answer 23

Microbial they make their own antibodies

Question 24

Bacteria’s Cell Wall

Answer 24

Provides protection

Question 25

Capsule

Answer 25

A sticky layer of polysaccharide or protein
On the outside of cell wall
Helps to stick to others

Question 26

Answer 32

Rod-Shaped Bacteria

Question 33

Spirilli

Answer 33

Spiral-Shaped Bacteria

Question 34

Gram-Positive Bacteria

Answer 34

Purple

No outer peptidoglycan

Question 35

Gram-Negative Bacteria

Answer 35

Pink
outer peptidoglycan (prevents stain)

Question 36

What is the point of gram staining?

Answer 36

Antibodies, if gram-positive then easier to kill because there is no protective layer

transformation

Answer 40

Where the bacteria takes new genes from its surroundings, usually died bacteria
