The legs of crocodiles a
homologous structures
Both organisms benefit from this type of symbiotic relationship.
mutualism
Which organisms have the most available energy in a food pyramid?
Producers
Copy this strand of DNA: AGC TGT CGC
TCG ACA GCG
Long term relationship where one organism benefits and the other organism is hurt or harmed.
Parasitism
What type of adaptation is it when an organisms blends into the environment to avoid predators?
Camoflauge
What type of relationship is it when organisms are fighting for resources.
Competition
tRNA carries amino acids to the mRNA on the ribosome. The amino acids join together to form a polypeptide chain.
How much energy is passed on from one trophic level to the next?
10%
movement of ions, and molecules across cell membranes without the need for energy input
passive transport (diffusion, facilitated diffusion, osmosis)
What is the difference between mitosis and meiosis? Give AT LEAST 3 differences.
Mitosis - 1 cell division, daughter cells are identical, daughter cells have the same number of chromosomes as parents, no crossing over, somatic cells,
Meiosis - 2 cell divisions, daughter cells are unique, half as many chromosomes as parents, crossing over, gametes (sperm and egg)
What happens when an enzyme is exposed to temperatures high above its optimal range?
the enzyme becomes denatured
What biomolecule serves as a fast source of energy?
carbohydrates (glucose)
What is an enzyme? What do most enzyme names end in?
A protein that speeds up chemical reactions. -ose
If the producers contain 10,000 Kcal, then how much energy will the secondary consumers contain?
100 Kcal
Which type of movement across a cell's membrane requires energy supplied by ATP?
Active transport
What is the monomer of starch and glycogen (carbohydrates)
Monosaccharides (single sugars)
What is the difference between bottleneck effect and founder effect?
Bottleneck effect is a random shrinking of the population, often a natural disaster. Founder effect is when populations move.
What is the Cellular Respiration equation?
C6H12O6 + 6O2 --> 6CO2 + 6H2O + 36/38 ATP
(GO --> COW!)
What is the monomer of a nucleic acid? What are the three parts of this monomer?
Nucleotide - nitrogenous base, phosphate, sugar
