4 What are the 4 major biomolecules of life?
5 Proteins Carbohydrates Lipids Nucleic Acids
6 What is the name for special proteins that speed up chemical reactions in the body without being used up in the process?
8 What is the equation for Photosynthesis?
9 6CO 2 + 6H 2 O C 6 H 12 O 6 + 6O 2
10 Compare & Contrast the Krebs and Calvin Cycles
11 Calvin – part of photosynthesis - CO 2 and sunlight energy are put together into glucose Krebs – part of respiration - Glucose is broken down into CO 2 and energy is released
12 What are the 6 levels of organization in Ecology?
13 Organism Population Community Ecosystem Biome Biosphere
14 Someone come to the board and draw/label an exponential and logistic growth curve. Which is more true to nature?
16 Differentiate between the following types of symbiosis: Mutualism Parasitism Commensalism
17 Mutualism – both partners benefit Parasitism – one organism benefits while the other is harmed Commensalism – one organism benefits while the other is unaffected
Environmental Problems: 1.What are the 3 primary Greenhouse gasses and what do they cause 2.What is the result of fat-soluble pollutants moving up the food chain and what is this process called? 18
19 1. CO 2, CH 4, & H 2 O – cause global warming 2. Biomagnification results in fat- soluble pollutants concentrating in top predators in a food chain
Define the following terms: Ecological Succession Ecological Equivalents Intraspecific Competition Invasive Species Type 1 Growth Curve 20
21 Ecological Succession – gradual change in the plant species of an ecosystem over time Ecological Equivalents – organisms that have evolved similar traits due to similar habitats Intraspecific Competition – competition between members of the same species Invasive Species – species that do not belong in an environment Type 1 Growth Curve – reproductive strategy in which most offspring live until they reach close to their maximum life span and then die off
22 What was the name of the guy who came up with the theory of evolution and what two types of animals on what island chain did he study in order to come up with his theory?
23 Charles Darwin studied finches and giant tortoises on the Galapagos Islands
24 What 4 types of isolation may lead to speciation?
25 Reproductive Temporal Geographic Behavorial
26 What types of selection are shown in the following figures? Which of the 3 will most likely cause one species to speciate into two?
27 Stabilizing Directional Disruptive
28 Differentiate between homologous, analogous, and vestigial structures
29 Homologous – similar structure but different function (shows evolutionary relationship) Analogous – similar function but different structure (shown no evolutionary relationship) Vestigial – had a function in an earlier ancestor but no longer Human hand Bat wingMole foot Bat wing Fly wing
31 Divergent – when a species splits into several species and they get more different from one another over time Convergent – when unrelated species begin to become more similar to each other over time due to similar niches Coevolution – when two species evolve in response to each other
32 What are the 3 tenants of the Cell Theory?
33 1. All organisms are made of cells. 2. All existing cells are produced by other living cells. 3. The cell is the most basic unit of life.
34 What are the two main types of cells and how does one distinguish between the two types?
35 Prokaryotic and Eukaryotic Eukaryotic cells are larger, have a nucleus, and have organelles
36 Explain what is going on in the following pictures
37 Simple Diffusion Facilitated Diffusion Active Transport
38 What are 4 main differences between mitosis & meiosis?
39 MitosisMeiosis Creates diploid somatic cellsCreates haploid gametes One round of divisionTwo rounds of division Creates identical daughter cellsCreates unique sperm & eggs Homologous pairs never crossCrossover of genes in homologous chromosomes
40 Name the following organelles and describe their function
41 Answers vary depending on letters asked
42 What is the central dogma of molecular genetics?
37 replication transcription translation
44 In Teenage Mutant Ninja Turtles, green shells are dominant over brown shells. Leonardo, who is heterozygous for a green shell, marries the lovely Mona Lisa, who has a brown shell. What are the genotypic and phenotypic ratios of their possible offspring?
46 What shape does DNA form into, what is the name for the monomers that make up the nucleic acid, what molecules form the backbone, and what molecules form the “rungs” of the ladder?
47 DNA is a double helix of nucleotides. The sides of the double helix are made of the sugars & phosphates and the rungs of the ladder are made of nitrogenous bases hydrogen bond covalent bond
48 Differentiate between dominant/recessive genes, codominant genes, genes that show incomplete dominance, and polygenetic traits
49 Dominant/recessive – normal patterns (recessive trait is only seen in homozygous recessive organisms) Codominance – both versions of gene are seen completely Incomplete – blending of both versions of the gene Polygenetic – multiple genes affect the phenotype
50 Name the process pictured below and identify the labeled structures 1 2 3 4 5 6
