Evolution and Biology Basics

Question 1

What is descent with modification?

Answer 1

All life on Earth has a common ancestor

Question 2

What are the 3 domains of life?

Answer 2

Archae
Bacteria
Eucarya

Question 3

What makes something a living thing?

Answer 3

Have order (organization of complex systems)
Can reproduce
Can grow and develop
Can utilize energy for work
Can respond to the environment
Regulates internal and external environment
Adapts to changing environment over generations

Question 4

What are the most important elements for life?

Answer 4

Carbon, oxygen, hydrogen, nitrogen, phosphate and sulphur

Question 5

What are organic molecules?

Answer 5

Molecules involved in the processes of life
Contain Carbon, hydrogen, and usually oxygen.
High energy molecules

Question 6

How can organic molecules be classified?

Answer 6

4 general groups

1. Carbohydrates
2. Proteins
3. Lipids
4. Nucleic Acids

Question 7

Describe carbohydrates and give some examples

Answer 7

Chains and or rings of C, H, O
Glucose (energy)
Starches energy for plants
Glycogen energy for animals

Question 8

Describe proteins and give some examples

Answer 8

Most varied and complex organic molecules
Made up of amino acid and sub units
Enzymes (catalyst for biological reactions), hormones,

Question 9

Describe lipids and give some examples

Answer 9

Repels water
Structural
Used for energy storage
Has buoyancy

Question 10

Describe nucleic acids and give some examples

Answer 10

Chains of repeating subunits-nucleotides
DNA or RNA 
DNA is blueprint for all of life 
Responsible for the code necessary for production of proteins 
Only 4 nucleotides total for all of life

Question 11

What is the equation of photosynthesis?

Answer 11

CO2 + H20 + solar energy = glucose + oxygen

All about food and air

Question 12

What is respiration?

Answer 12

The breaking apart of organic molecules in order to release and use energy
The reverse of photosynthesis
Simple sugar + oxygen = carbon dioxide + water + chemical energy

Question 13

What are autotrophic organisms?

Answer 13

Harness energy from sun to make glucose then use it in respiration to release energy to make more complicated organic molecules to grow and divide.

Question 14

What are heterotrophic organisms?

Answer 14

Harness energy from consuming the organic matter in autotrophs or other heterotrophs then use it in respiration to release energy to make more complicated organic molecules to grow and divide.
