100
4 common elements found in all living organisms
What is Carbon, Hydrogen, Nitrogen, and Oxygen
100
circular pieces of RNA that infect plants
What is Viroids
100
Where the First Stage of Photosynthesis occurs
What is Thylakoid Membrane
100
Alternate versions of a gene.
What are Alleles
100
1809-1882, rode on the HMS beagle, developed ideas of natural selection and wrote On the Origin of Species
Who is Charles Darwin
200
The structural carbohydrate molecules
What is Cellulose and Chitin
200
A virus that infects bacteria; also called a phage.
What is Bacteriophage
200
structure through which CO2 enters a plant and water vapor and oxygen leave
What is stomata
200
a map of multiple generations and their genotypes as well as phenotypes
What is a Pedigree
200
Hardy-Weinberg Equation
What is p2 + 2pq + q2 = 1 where p2 is equal to the frequency of the homozygous dominant in the population, 2pq is equal to the frequency of all the heterozygotes in the population, and q2 is equal to the frequency of the homozygous recessive in the population.
300
Organic molecules are those that contain at least
What is Carbon and Hydrogen
300
An enzyme encoded by certain viruses (retroviruses) that uses RNA as a template for DNA synthesis
What is Reverse Transcriptase
300
site of Calcin cycle in C4 plants, wrapped around veins of leaf
What is Bundle Sheath Cells
300
Ratio of outcome of Rr x rr
What is 2Rr:2rr
300
the elimination of the extreme individuals
What is Stabilizing Selection
400
If a segment of DNA has 20% adenine in its base composition, what percent thymine is there?
What is 20%
400
Describe the Lysogenic cycle and its mode of attacking
What is Phage reproduction cycle that does not destroy the host cell. 1. Virus inserts its genetic material into host cell (called a "prophage") 2. The viral DNA incorporates into the bacterial chromosome. 3. The bacteria reproduces normally, transferring the viral DNA to its daughters
400
enzyme that catalyzes first step of Calvin cycle
What is RuBisCo
400
meiosis in which pairs of homologous chromosomes do not separate properly/sister chromatids do not separate
What is nondisjunction
400
when conditions favor individuals at both extremes of a phenotypic range over individuals with intermediate phenotypes
What is Disruptive Selection
500
Ions necessary for nerve function
What is Na+, Ca+, CI-
500
Describe the process of the Lytic Cycle and mode of attacking the host.
What is Phage reproduction cycle that culminates in death of the host cell. 1. Virus inserts its genetic material into host cell. 2. Phage DNA & protein are synthesized and assembled into phages within the host cell. 3. The cell lyses, releasing the phages.
500
a process in which the movement of protons down their concentration gradient through ATP synthase channels phosphorylate ADP into ATP
What is Chemiosmosis
500
"cell suicide" cells with harmful mutations will kill themselves for the benefit of the body
What is apoptosis
500
5 Steps to Natural Selection
What is Step 1:produce more offspring than can survive Step 2:variations occur in a species Step 3: competition for limited resources Step 4: better adapted organisms are more likely to survive and reproduce Step 5:change in a population will most likely occur
