Exam 1
Elements all living things have
carbon and hydrogen
Domains
- Bacteria 2. Archaea 3. Eukarya
Domain Eukarya consists of these kingdoms
- Protists 2.Anamalia 3. Plantae 4.Fungi
Are a part of Domain Eukarya, are unicell. ex. algae
Kingdom Protists
Are a part of Domain Eukarya, multicellular, heterotrophic, ex. humans
Kingdom Animalia
Are a part of Domain Eukarya, decomposers, ex.mushrooms
Kingdom Fungi
Are a part of Domain Eukarya, photosynthesise
Kingdom Plantae
Cells that have no membrane-bound nucleus
Prokaryotic cells
Cells that have a membrane-bound nucleus
Eukaryotic cells
How to write scientific name
Genus species and underlined
How to type scientific name
Genus species and italicized
Large and complex cells
Eukaryotic cells
Layers of microorganisms that can stick to eachother and other things (your teeth)
Biofilm
Metabolism of bacteria
fermentation of sugars, byproducts can be acids
Why does some bacteria produce a pigment?
To protect from UV damage
Take nutrients from another living thing to get energy
Heterotrophic
Classification
Kingdom, Phylum, Class, Order, Family, Genus, Species
Classification of Humans
Eukarya, Animalia, Chordata, Mammalia, Primates, Hominidae, Homo, sapiens
One or more populations of organisms who share similar physical and functional connections and can interbreed and produce fertile offspring
Species
The ability to stand upright and walk on two legs
Bipedalism
The ability to grasp objects
Opposable thumbs
Maintaining and internal balance, responding and adjusting to stimuli (regulating temperature)
Homeostasis
Bipedalism, Opposable Thumbs, Homeostasis, Large Brain, Capacity for Language
Features of humans
Atom- Molecule- Cell- Tissue- Organ- Organ system- Organism- Population- Community- Ecosystem- Biosphere
Biological Organization
- Observe and Generalize 2. Make a hypothesis 3. Make a testable prediction 4. Experiment and observe 5. Modify and repeat if necessary
Scientific Method
A carefully planned and executed manipulation of the natural world
Experiment
Cannot be proven true, only supported or disproved
Hypothesis
Broad, extensively tested, supported over time, explain a broad range of facts, have a high degree of reliability, may be refuted in the future
Theory
Wearing socks does not cause cancer. But people who wear socks may happen to have cancer.
Correlation vs Causation
Total Magnification
Mag of ocular X objective lens
Ocular Magnification
10x
Objective magnification
4x, 10x, 40x, 100x
Microscope part: Does not magnify, collects and directs light through the slide
Condenser
Microscope part: Adjusts condenser light
Iris Diaphragm
Microscope term: Once focused, object generally remains in focus
Parafocal
Microscope part: Focus
Course or Fine
The process by which living organisms maintain a fairly constant internal environment despite changes in the external environment is known as
Homeostasis
Which kingdom in Domain Eukarya contains multicellular photosynthesizers
Plantae
Which one of the following sequences is CORRECT in terms of level of organization from least to most complex?
a) tissues, organ systems, population, cells, organism
b) atoms, cells, organs, community, population
c) cells, tissues, organs, organ systems, organism
d) atoms, cells, organism, organ systems, ecosystem
c
A group of similar organisms capable of interbreeding and producing fertile offspring is a(n)
Species
Groups of these make up a ‘population’
Species
The lenses that you look though on a compound light microscope
Ocular
