Question
Answer
Photosynthesis   6 CO2 + 6 H20 light= C6H12O6 + 6 O2 In Chlorophyll  
🗑
Cellular Respiration   C6H12O6 + 6 O2 = 6 CO2 + 6 H20 In Mitochondria  
🗑
Glycolysis   First step in Cell Rep. Anaerobic In Cytoplasm  
🗑
Krebs Cycle   Second step in Cell Rep. Aerobic In Mitochondria  
🗑
Electron Transport chain   Last step in Cell Rep. Aerobic In Mitochondria  
🗑
Lactic Acid Fermentation   Enzymes convert pyruvate into acid and skeletal muscles produce it to supply oxygen.  
🗑
Alcohol Fermentation   Converts pyruvate into ethyl and carbon dioxide.  
🗑
Sexual Reproduction   Requires two of the same species to produce offspring. Offspring is genetically different.  
🗑
Asexual Reproduction   Does not require a mate to reproduce. Creates offspring that is genetically identical to the parent.  
🗑
Malignant Tumors   Cancerous, it destroys healthy tissue.  
🗑
Benign Tumors   Non-cancerous, it does not spread.  
🗑
Differentiation   Process where cells become specialized.  
🗑
Crossing-Over   Chromosomal segments are exchanged between a pair of homologous chromosomes.  
🗑
Zygote   Contains 2n number of chromosomes.  
🗑
Genes   Chromosome that carries information for proteins for a specific trait.  
🗑
Alleles   Different forms of a single gene passed down from generations.  
🗑
Heterozyous   Two different alleles for a particular trait.  
🗑
Homozygous Dominant   Two dominant alleles that are expressed.  
🗑
Homozygous Recessive   Two alleles are the same with no dominant allele expressed.  
🗑
Phenotype   Physical characteristics of a allele pair.  
🗑
Genotype   Organism's allele pairs.  
🗑
Punnett Square   Predicts possible offspring of two genotypes.  
🗑
Dominant   Allele that is always expressed.  
🗑
Recessive   Allele that is only expressed if there is no dominant allele present.  
🗑
Gregor Mendel   Performed cross-pollination in pea plants.  
🗑
Genetic Engineering   Technology that manipulates DNA of one organism.  
🗑
Transcription   DNA code is transferred to mRNA in the nucleus.  
🗑
Translation   Translates protein.  
🗑
Codon   Three bases code in DNA or mRNA.  
🗑
Nucleotide   Made up of five carbon sugar, phosphate and nitrogenous base.  
🗑


   

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.
