Biology |
The study of life |
|
|
Levels of biological orgatization |
Atom Molecule Cell Tissue Organ Organ system Organism Population Community Ecosystem Biosphere |
|
|
Taxonomy classification levels |
Domain Kingdom Phylum Class Order Family Genus Species |
Dumb kids playing catch on free way get smashed |
|
Steps to scientific method |
Observation- using knowledge to form question (hypothesis) Hypothesis- explanation Test- observation or experiment, proves or disproves hypothesis. Conclusion- results. Rejecte or supporte hypothesis |
|
|
Qualitative vs. Quantitative date |
Qualitative- deals with description. Data can be observed, colors, texture, smell,taste, etc. Quantitative- deals with numbers. Data can be measured, length, width, area,volume, levels, cost,ages,etc. |
|
|
Hypothesis vs. Threory |
Hypothesis - suggested explanation or educated guess Theory - a tested, well-substained explanation for proven factors |
|
|
Anecdotal vs. Credible evidence |
Anecdotal - stories shared by people. Not a hard fact. Credible - evidence worth of belief. Jury decides if it's credible |
|
|
Types of bonds (3) |
Covalent - shared electrons Ionic - transferred electrons Hydrogen- weak bond between water molecules |
|
|
4 macromolecules |
Lipids - stores energy, FATS Proteins - build, control, move muscles Carbohydrates - energy from whole grain foods Nucleic acids - DMA, RNA. Controls you |
|
|
Photosynthesis formula |
6 CO2 + 6 H2O ==> 6 O2 + C6H12O6 |
|
|
Photosynthesis reactions (2) |
Light reaction - makes ATP and NADPH (carries energy), happens in chloroplast. Calvin cycle - makes G3P (3 carbon molecule), happens in stroma |
|
|
Why do leaves turn color in the fall? |
Chloraphyll breaks down, turns then yellow/orange |
|
|
Isotonic, hypotonic, and hypertonic solutions |
Isotonic- concentration is equal on both sides Hypotonic- concentration is greater on the inside. Hypertonic- concentration is greater on the outside |
|
|
Roles of CO2, H2O, NADPH and O2 in photosynthesis |
Carbon dioxide is used with water to create oxygen and NADPH |
|
|
Endocytosis and exocytosis |
Endocytosis- large particles moving into cell Exocytosis- large particles moving out of cell |
|
|
Purpose of glycoses |
To oxidize glucose and produce pyruvate. provides ATP and NADH |
|
|
Citric acid cycle products |
NADH, 2 ATP,FADH2. Sugar is cut up completely |
|
|
Which evolved first, unicellular or multicellular organisms? |
Unicellular |
|
|
What is a specialized cell? |
Cells modified to carry out a specific task |
|
|
What type of organisms need specialized cells? |
Multicellular organisms |
|
|
Eukaryote vs. Prokaryote |
Eukaryote has nucleus and membrane bound cells; prokaryote don't |
|
|
What type of cell are bacteria? |
Prokaryotes |
|
|
Examples of eukaryotes |
Fungi Protist Plants Animals |
|
|
What is a lipid bilayer? |
Fatty acids organized in two sheets |
|
|
Which organelles are found in only plant cells? |
Cell wall and chloroplasts |
|
|
Which organelles are found in both animal and plant cells? |
Cell membrane, nucleus, nuclear membrane, cytoplasm, E.R., ribosome, mitochondria, vacuole and lysosomes |
|
|
What organelle is more abundant in a active eukaryotes cell? |
Mitochondria, its the power house of the cell |
|
|
Osmosis vs. Diffusion |
Osmosis - water molecules from high concentration through a semipenetrable membrane to low concentration. Diffusion - air molecules from high to low concentration |
|
|
Dna is replicated in what phase? |
Telophase |
|
|
Fertilization |
Union of two cells from to individual organisms. Sperm meets egg |
|
|
Transcription vs translation |
Transcription - DNA to RNA, product occurs in mRNA, happens in nucleus, requires RNA polymerase. Both - C,A,G,U and nucleotides Translation - RNA to protein, product is in polypeptide, happens in ribosome, uses reagents to create polymerase chain. |
|
|
IMPAT |
interphase Metaphase Prophase Anaphase Telophase |
|
|
Somatic vs gamete cell |
Somatic - full set of chromosomes Gamete - has haploid(half) membrane |
|
|
What are the 3 domains? |
Viruses Bacteria Protozoan |
|
|
Species |
Able to breed and produce fertile offspring |
|
|
Genetic drift |
More of one gene is present by chance |
|
|
Polyploidy |
Different species Plants can be triploid or tetraploid |
|
|
Allopatric vs. Sympatric speciation |
Allopathic requires physical separation ( geographic isolation) Sympatric does not |
|
|
Silicate cell wall |
Surrounds some bacteria, protects bacteria from surroundings |
|
|
Bacteria shape |
Rod shaped |
|
|
Amoeba vs trypanosomes movement |
Amoeba -moves by shifting body shape Trpanosome- moves by "squishing" |
|
|
Fertilization vs. Pollination |
Fertilization requires pollination but pollination doesn't always mean the plant will be fertilized |
