🗑
|
||||
| proteins | biomolecule composed of nitrogen, carbon, hydrogen and oxygen; made up of monomer amino acids; enzyme is an example
🗑
|
||||
| nucleic acids | biomolecule made up of nucleotides; nucleotides contain a phosphate sugar and nitrogen base; examples include DNA and RNA
🗑
|
||||
| monomer | single unit ; small piece of biomolecule
🗑
|

| organic molecule | An organic compound always contains carbon; Examples : carbohydrates, lipids, proteins and nucleic acids.
🗑
|
||||
| prokaryotic | an organism whose cell generally lacks a true nucleus Examples: bacterial cells
🗑
|
||||
| eukaryotic | organism possessing a membrane-bound nucleus and organelles; animals, plants, fungi, and protists
🗑
|
||||
| homeostasis | The tendency of an organism or a cell to regulate its internal conditions, usually by a system of feedback controls or feedback loops, so as to stabilize health and functioning, regardless of the outside changing conditions ex: sweating when hot
🗑
|
||||
| deoxyribonucleic acid | double-stranded nucleic acid found in the nucleus which provides instruction for making proteins; provides hereditary information; DNA

🗑
|
||||
| cell cycle | components include interphase, mitosis and cytokinesis
🗑
|
||||

🗑
|
||||
| mitosis | part of cell cycle; division of the nucleus; includes prophase, metaphase, anaphase and telophase
🗑
|
||||
| cytokinesis | part of cell cycle; division of cytoplasm and organelles except nucleus
🗑
|
||||
| cell differentiation | specialization of cells for a particular function
🗑
|
||||
| cancer | uncontrolled cell division; creates tumors and interferes with normal cell function
🗑

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.
