|---|---|---|---|---|---|
| Meiosis | A Special type of cell division or cell cycle undergone by body cells in order to turn them into sex cells,necessary for sexual reproduction.In Meiosis, the Mitosis cell cylce happens twice ending with the creation of 4 cells with 1/2 the genetic material
🗑
|
||||
| Metaphase | The stage of Mitosis and Meiosis in which condensed and highly coiled chromosomes, carrying genetic information, align in the middle of the cell
🗑
|
||||
| Mitosis | The stage of the cell cycle during which the cell's nucleus divides into 2 new nuclei
🗑
|
||||
| Prophase | The stage of Mitosis or Meiosis in which the chromatin condenses into a highly ordered structure called a chromosome in which the chromatin becomes visible
🗑
|
||||
| Telophase | The stage of Mitosis or Meiosis when two daughter form around each pair of chromatids in the new cell. Telophase accounts for approximately 2% of the cell cycle's duration
🗑
|
||||
| Alleles | The different forms of a gene
🗑
|
||||
| Dominant Allele | The form of a gene whose charecteristics will be displayed if the Allele is present
🗑
|
||||
| Genotype | The genetic makeup of an organism or group of organisms with reference to a single trait,set of traits,or an entire complex of traits.
🗑
|
||||
| Phenotype | The appearance of an organism resulting from the interaction of the genotype and the enviroment
🗑
|
||||
| Probability | The relitive possibility that an event will occur, as expressed by the ratio of number of actual occurrences to the total number of possible occurrences
🗑
|
||||
| Punnett Squares | A Type of grid that can indicate all the possible outcomes of a genetic cross.
🗑
|
||||
| Recessive Allele | The form of a gene whose charecteristics will only be displayed if in the presence of a matching copy of the same Allele
🗑
|
||||
| Biological Inheritance | This is the process in which a living organism produces another organism that shares its same traits
🗑
|
||||
| Environmental Factors | The expression of genes in an organism can be influenced by the environment. External Factors can still influence the way an organism develops and functions
🗑
|
||||
| Genetic Disorder | This is caused by abnormalities in genes or chromosomes.Some Genetic Disorders are passed down from the parents' genes, but others are always or almost always caused by new mutations or changes to the DNA
🗑
|
||||
| Platelets | Small,round cell fragments containing no nuclei that are found in the blood and help in the clotting of blood.
🗑
|
||||
| Red Blood Cells | A disk-shaped cell in the blood that contains hemogoblin,lacks a nucleus,and tranports oxygen and carbon dioxide to and from the tissues
🗑
|
||||
| Valve | A flap-like stucture in a hollow organ,such as the heart,that controls the one-way passage of fluid through that organ
🗑
|
||||
| Vein | Any of the blood vessels that carry deoxygenated blood toward the heart from the body's cells,tissue,and organs
🗑
|
||||
| Ventricle | A chamber of the heart that recives blood from one or more Atria and pumps it by muscular contraction into arteries
🗑
|
||||
| White Blood Cells | Colorless cells in the blood that help combat infection
🗑

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.
