|---|---|---|---|---|---|
| levels of organization atomic level | atoms are defined as the smallest unit of an element that still maintains the property of that element
ex. carbon, hydrogen, oxygen
🗑
|
||||
| levels of organization molecular level | atoms combine to form molecules which can have entirely different properties than the atoms they contain
ex. water, DNA, carbohydrates
🗑
|
||||
| levels of organization cellular level | cells are the smallest unit of life. cells are enclosed by a membrane or cell wall and in multicellular organisms often perform specific functions
ex. muscle cell, skin cell, neuron
🗑
|
||||
| levels of organization tissue level | tissues are groups of cells with similar functions
ex. muscle, epithelial, connective
🗑
|
||||
| levels of organization organ level | organs are two or more types of tissues that work together to complete a specific task
ex. heart, liver, stomach
🗑
|
||||
| levels of organization organ system level | an organ system is group of organs that carries out more generalized set of functions
ex. digestive system, circulatory system
🗑
|
||||
| levels of organization organism level | an organism has several organ systems that function together'
ex. human
🗑
|
||||
| prokaryotes | -single-celled organisms that lack internal structures surrounded by membranes
-lack a true nucleus
ex. bacteria, archaea
🗑
|
||||
| eukaryotes | -single-celled and multi--cellular organisms that have cells containing internal, membrane-bound structures
-have a true nucleus containing the cell's DNA
🗑
|
||||
| unlike prokaryotic cells, eukaryotic cells have the capacity to... | assemble into multi-cellular organisms
🗑
|
||||
| inside eukaryotic cells are membrane-bound structures called... | organelles
🗑
|
||||
| what are life's levels of organization? | atom, molecule, organelles, cell, tissue, organ, organ system, organism, population, community, ecosystem, biome, biosphere
🗑
|
||||
| why is water a polar molecule? | -because the oxygen side is slightly negative and the hydrogen side is slightly positive
-the three atoms are constantly at a tug of war for their electrons
-polarity helps water to bind with other substances
🗑
|
||||
| cohesion | water tends to stick together
ex. droplets of dew on grass
🗑
|
||||
| surface tension | the top layer of water is very strong
ex. insects can walk on water
🗑
|
||||
| adhesion | water tends to stick to OTHER things
ex. water sticks to glass after washing
🗑
|
||||
| capillary action | movement of water against gravity
ex. allows water to rise narrow tubes in plant stems
🗑
|
||||
| high specific heat | water is able to resist changes in temperature
ex. helps organisms retain body heat and resist freezing in cold temps
🗑
|
||||
| universal solvent | water can dissolve many things
ex. putting sugar in tea
🗑
|
||||
| solvent | the material that is doing the dissolving
🗑
|
||||
| solute | the material that is dissolved
🗑
|
||||
| hydrophobic | not mixing with water
🗑
|
||||
| hydrophilic | mixing with water
🗑
|
||||
| density | the degree of compactness of substance
ex. ice is less dense than water
🗑
|
||||
| which statement best describes an effect of the low density frozen water in a lake? | when water in a lake freezes, it floats, providing insulation for organisms below
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
