What is activation energy?
The amount of energy needed
to make a chemical reaction start
There are two types of sugars what are they? *You must say there full name*
DNA: Deoxyribonucleic Acid
RNA: Ribonucleic Acid
Protein Synthesis requires two steps what are they?
Transcription and Translation
Describes qualities
- Examples:Green liquid, Large hole, Sour taste, Sweet smell
Quantitative: Uses numbers to measure something
- Examples: 4 feet long, 6 legs, 7.2 grams, 100 mL
What are the 6 levels of ecological organization?
Organism
Community
Population
Ecosystem
Biome
Biosphere
Endothermic: Absorbs energy (in the form of
heat or light)
- Ex. Photosynthesis
Exothermic: Releases energy (in the form of
heat or light)
- Ex. Cellular Respiration
There are three parts that make up a nucleotide what are they? *you must list all the base pairs as well*
Phosphate
Sugar
Nitrogen Base Pairs:
Adenine--> Thymine
Guanine--> Cytosine
There are 3 types of RNA what are they? Make sure to explain what they stand for.
mRNA (messenger)
tRNA (transfer)
rRNA(Ribosomal)
Identify which description is accuracy and which is precision:
1. How close your measurements are
to each other
2. How close your measurement is to
the correct/accepted value
1. Precision: How close your measurements are
to each other
2. Accuracy: How close your measurement is to
the correct/accepted value
Describe what a Biome is? And 2 examples.
Biome: multiple ecosystems that share similar
characteristics but are located in different
parts of the planet
Examples: Tundra, Tropical Rainforest, Taiga, Desert
There are 5 ways to change the rate of a chemical reaction what are they?
Temperature
pH
Substrate Concentration
Catalysts
Competitive Inhibitor
1. DNA replication happens in the nucleus in what phase?
2. DNA considered to be _____________ because the replicated DNA will have "1/2 new" and "1/2 old."
1. S(synthesis) phase
2. Semi-conservative
Fill in the blank:
In the Central Dogma of Genetics:
________ (instructions) are located in the nucleus but cannot leave.
But ___________ are made in the ribosomes
DNA (instructions) are located in the nucleus but cannot leave.
But proteins are made in the ribosomes
2. Which one is cause and which one is effect?
1. “If (IV) then (DV) ”
2. IV = Independent variable = Cause
DV = Dependent variable = Effect
Describe what a population, community, and ecosystem is?
Population: multiple organisms of the same
species living together
Community: multiple populations of different species
living together
Ecosystem: community PLUS all of the abiotic factors in the environment
1. What are two ways producers get energy?
2. Name 4 types of consumers
3. Explain the rule of 10
1. Photosynthesis and Chemosynthesis
2. Herbivores, Carnivores, Omnivore, Detritivores
3. As energy flows from organism to organism, it is used for metabolism and/or converted to heat
- Because of this, the next organism on the chain only receives 10 PERCENT of the energy obtained in the previous level
- The other 90% is used or “lost” as heat
