Ecosystem   Forests, grasslands, deserts, etc...  
🗑
Communities   The organisms inhabiting an ecosystem  
🗑
Population   consists of all the individuals of a species living within the bounds of a specified area.  
🗑
Organisms   Individual living things  
🗑
Organs and Organ systems   A body part consisting of two or more tissues  
🗑

🗑
Eukaryotic Cell   Subdivided by internal membranes into various membrane-enclosed organelles. The largest organelle is the nucleus.  
🗑
Prokaryotic Cell   The DNA is not separated from the rest of the cell by enclosure in a membrane-bounded nucleus. Also lacks other kinds of membrane-enclosed organelles.  
🗑
Chromosomes   contain almost all of a cell's DNA  
🗑
DNA   (Deoxyribonucleic Acid) The substance of genes  
🗑
Genes   The units of inheritance that transmit information from parents to offspring.  
🗑
Enzymes   Speed up specific chemical reactions, a type of protein  
🗑
RNA   Controls protein production  
🗑
Nucleotides   Strands of DNA  
🗑
Genome   The entire make-up of genetic instructions that an organism inherits  
🗑
Negative feedback   Accumulation of an end product of a process slows that process  
🗑
Positive feedback   Accumulation of an end product speeds up its production  
🗑
Classifications of life   Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species  
🗑
Domain Bacteria   The most diverse and widespread prokaryotes  
🗑
Domain Archaea   Live in Earth's extreme environments, such as salty lakes and boiling hot springs  
🗑
Domain Eukarya   Protists, Kingdom Fungi, Kingdom Plantae, Kingdom Animalia  
🗑
Protists   Unicellular eukaryotes  
🗑
Kingdom fungi   Absorb nutrients after decomposing organic material  
🗑
Kingdom Plantae   Consists of multicellular eukaryotes that carry out photosynthesis  
🗑
Kingdom Animalia   Consists of multicellular eukaryotes that ingest other organisms  
🗑
Three domains of life   Domain bacteria (prokaryotic), domain archaea (prokaryotic), domain eukarya  
🗑
Domain eukarya   Contains Kingdoms Plantae, Fungi, and Animalia  
🗑
Discovery Science   Describes natural structures and processes as accurately as possible through careful observation and analysis of data.  
🗑
Data   Recorded observations  
🗑
Hypothesis   A tentative answer to a well-framed question  
🗑
Deductive Reasoning   Reasoning that goes from the general to the specific  
🗑
Controlled Experiment   An experiment that is designed to compare an experimental group with a control group.  
🗑
Element   A substance that cannot be broken down to other substances by chemical reactions  
🗑
Compound   A substance consisting of two or more different elements combined in a fixed ratio.  
🗑
Main elements in the human body   Oxygen, Carbon, Hydrogen, Nitrogen, Calcium, Phosphorus  
🗑
Covalent Bond   The sharing of a pair of valence electrons by two atoms  
🗑
Electro negativity   The attraction of a particular kind of atom for the electrons of a covalent bond  
🗑
nonpolar covalent bond   Electrons are shared equally  
🗑
polar covalent bond   One atom is bonded to a more electronegative atom, the electrons are not shared equally  
🗑


   

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.
