Unit 1
1. Where does transcription take place?
2. Where does translation take place?
1. Nucleus
2. Ribosome
How many ATP is produced from Glycolysis?
2 ATP
Describe decomposition.
When the dead body of an organism is broken down, releasing carbon into the atmosphere and ground.
What does a half shaded-in circle on a pedigree represent?
A female carrier of a trait.
What is a vestigial structure.
A structure that has no more use.
What does DNA contain?
Genetic info
What is the difference between aerobic and anaerobic respiration?
Aerobic needs oxygen, anaerobic does not.
What are the four spheres?
Hydrosphere, geosphere, atmosphere, and biosphere.
If a trait skips a generation and then returns, is it what type of trait is it?
Recessive.
Describe convergent evolution.
When two creatures evolve due to similar environmental pressures.
What is the difference between mRNA and tRNA?
mRNA transfers copied genetic info to the ribosome, tRNA links with mRNA in the ribosome to get the correct amino acids.
Lipids.
What is a carrying capacity.
The maximum amount of organisms an environment can hold.
What is the difference between meiosis and mitosis?
Blanket definition.
If two groups of the same species are separated by a river, what might happen.
They will become different species.
What does DNA stand for?
Deoxyribose Nucleic Acid
What are the products of both photosynthesis and cellular respiration?
Photosynthesis: Oxygen and glucose
Cellular respiration: ATP, Carbon dioxide, and water.
What is the most likely cause of a deer population falling significantly after it reached over its carrying capacity?
The environment could not support the population anymore.
If you cross a homologous recessive and a heterozygous organism, what is the gene ratio you will get?
2/2/0
Describe the difference between homologous and analogous structures.
Homologous are similar structure, different use. Analogous is different structure, same use.
Name the three types of mutations and what causes mutations in the first place.
Insertion, deletion, and substitution. Mutations are caused by errors during DNA replication.
What two macromolecules contain nitrogen?
Nucleic acid and protein.
What is a possible restoration solution for an environment being overfished?
Laws limiting fishing, etc.
If you cross a flower that has red petals (recessive) and a heterozygous long stem with a flower that has heterozygous yellow petals and a homozygous long stem, how many of their children will be red and have a long stem?
Describe how after population of elephants that are hunted for their tusks, later members of the population might have no tusks without them being hunted?
Natural selection yada yada
