Cells
What biomolecule serves as a fast+quick source of energy?
carbohydrates (glucose)
What are the full names of the 4 bases of DNA ? *10 extra points if you can pair them correctly!
- Adenine + Thymine
- Guanine + Cytosine
Which organisms have the most available energy in a food pyramid?
Producers (Autotrophs)
What is natural selection?
Organisms with advantageous traits survive and pass those traits onto offspring to help them survive.
- i.e. Survival of the fittest.
True or False: When a flower reproduces, the pollen from the ANTHER moves to the top of the STIGMA. Then travels down the style to the OVARY to fertilize the OVULE.
TRUE!!!!!
How are cells regulated and checked to ensure that they are healthy to mature normally?
The checkpoints within the cell cycle.
What is cell specialization?
When cells specialize their DNA to be more mature in their job/purpose.
What type of relationship is it when organisms are fighting for resources.
Competition
How can we ensure that an ecosystem will remain stable or recover after the distrubance?
The ecosystem has to have BIODIVERSITY!!!
In flowers, red (R) is dominant over white (r). Two homozygous recessive flowers are crossed.
What is the probability that an offspring will be white?
100% white
Describe what gene expression is.
Gene expression is when a specific part of your DNA is shown or expressed.
What is cell differentiation?
When cells transform into different types of cells with a specific purpose.
What are the ingredients (reactants) needed for photosynthesis and what is made (products)?
(water) H20 + (Carbon Dioxide) CO2 + Sunlight ->O2 (oxygen) + (Sugar/Glucose) C6H12O6
What is the difference between Punctuated Equilibrium and Gradualism
- Gradualism: slow evolutionary changes over a long period of time
- Punctuated Equilibrium: Rapid changes followed by periods of stasis pattern that happened over a long period of time (shows new species arriving)
A farmer is trying to have straight hair sheep with long coats. Straight hair (S) is dominant over curly hair (s). Long coats are dominant (L) over short coats (l).Find and F.O.I.L. these parent genotypes:
Parent 1: Heterozygous dominant for both traits. Parent 2: Homozygous dominanat for both traits
Parent pairs:
- SsLl x SSLL
- SL. - SL
- Sl. - SL
-sL. - SL
-sl. - SL
True or False: Viruses can survive on their own and reproduce through the air alone (EXPLAIN)
- FALSE
1. Nonliving so they cannot live on their own
2. Needs a host cell to survive
3. They reproduce by entering a host cell and using their DNA to make viral DNA to spread.
What are the full names of the 4 bases for RNA? *10 extra points if you can pair them correctly
- Adenine + Uracil
- Guanine + Cyctosine
What are the two steps of protein synthesis in order?
- Transcription
- Translation
What is Biodiversity?
What are the parts of DNA?
1.Nucleotide
2. Nitrogenous base
3. Phosphate
4. Sugar
You can always tell the difference between an eukaryote and prokaryote cell based on the organization of their _________ __________.
Organization of genetic material/ nucleus
-Eukaryote have nucleus
-Prokaryotes don't have nucleus
Describe how a tumor is made in the human body.
What are the ingredients (reactants) needed for cellular respiration and what is made (products)? *Hint its the process of photosynthesis but backwards*
(Glucose)C6H12O6 + (Oxygen)6O2 --> (carbon dioxide) 6CO2 + (water) 6H2O + ATP (energy)
(GO --> COW!)
What describes the small changes over a long period of time causing the SPECIES TO TRANSITION?
Evolution
What mutation happened to this DNA:
Original: AGC TGT CGC
Mutated: TCG AACA GCG
Insertion/Addition happened because there was an "A" nitrogen base that was added.
