| chromatin | unwrapped DNA histones when cell is not dividing, found in neucleus |
| chromatid | single stick like DNA |
| chromosome | DNA material found in an X- shaped structure |
| DNA | what makes up the chromosome |
| number of chromosomes in human body cells | 46 |
| number of chromosomes in sex cells | 23 |
| cytokenisis | division of the cytoplasm of one cell into two new cells |
| replication | the process by which DNA copies itself during interphase |
| process of DNA replication: part one | DNA heicase unzips DNA at the gene site |
| process of DNA replication: part two | DNA polymerase enzyme builds mRNA |
| helix of DNA | double |
| helix of RNA | single strand |
| Relative size of DNA | Relative size of DNA |
| Relative size of RNA | skinny |
| DNA base | thymine |
| RNA base | uracil |
| who is Gregor Mendel | a monk who is known as the father of genetics |
| What did Mendel discover | how to cross breed plants and patterns |
| with what organism did Mendel do his work | pea plants |
| PS: DNA strand is _______ by DNA helicase | unzipped |
| PS: DNA strand is _______ to make mRNA | transcribed |
| PS: DNA travels from nucleus to ______ | ribosome |
| PS: at ribosome mRNA connects with _____ that is transporting | tRNA |
| PS: amino acid connects to each other by _____ ____ to make a protein | peptide bonds |
| homologous chromosomes | one of a pair of morphologically similar chromosomes |
| sex chromosomes | determine if boy or girl |
| autosomal chromosomes | all chromosomes that are not sex chromosomes |
| cancer | the uncontrolled growth of cells |
| recessive (genes and traits) | an allele that is masked by the presence of another allele for the same characteristic |
| dominant (genes and traits) | an allele that masks the presence of another allele for the same characteristic |
| phenotype | actual visible representation of a trait |
| genotype | genetic make-up of an organism |
| incomplete dominance | both alleles affect the phenotype (B. horse + W. horse = grey horse) |
| codominance | neither of the alleles fully mask the other (B. horse + W. horse = horse that is B. and W.) |
| haploid | having only one chromosome of each homologous pair |
| diploid | having both chromosomes of each homologous pair |
| double diploid | having two sets of diploid chromosomes |
| zygote | a dipliod cell that results from the fusion of gametes |
| gamete | a reproductive cell |
| sperm | male gamete |
| egg | female gamete |
| polar bodies | other female reproductive potential eggs that won't be used for reproduction |
| sex linked traits | genes carried by chromosomes |
| sex influenced traits | genes that are influenced by whether the organism is male or female |
| purebred pairs | AA or aa |
| hybrid pairs | Aa |
| three reasons for cell division to occur | to reproduce, for efficiency (i.e. too big = inefficient), replace dead cells |
| prophase | membranes dissolve, chromosomes visible, aster & spindles form |
| metaphase | chromosomes line up at center |
| anaphase | split centromeres, chromosomes move to sides |
| telophase | nuclear membranes re-form, chromosomes change back into chromatid |
| males: end product of meiosis | sperm |
| females: end product of meiosis | polar bodies + egg |
| crossing over | an exchange of genetic information allowing for a greater species variety |
| why more males are colorblind, hemophiliac than females | these conditions are carried on the X chromosome. women have XX man just X (both X's would have to carry the condition for women to be afflicted) |
| who determines the sex of the child | father; because he can provide X or Y but mother can only provide X |
| why is the Human Genome Project important | it is the coding of all of the bases in a human's chromosome. With this information scientists can work on curing genetic diseases |
| cardio vascullar | moves O2 & CO2, kills germs / bacteria, keeps you warm |
| respiratory | moves O2 & CO2, moistens filters and warms air, supplys oxygen for the metabolic reactions that release energy and produce ATP |
| skeletal | supports / forms body shape, protects delicate organs, stores minerals |
| muscular | moves: fluids, blood, and you |
| excretory / urinary | filters waste, moves waste, cleans blood |
| digestive | takes in nutrients, filters out waste, keeps you alive |
| what is blood pressure | amount of pressure in your arteries |
| how is blood pressure measured | the flow of blood is stopped in the arm with air pressure. then the heartbeat is listened to for systolic and diastolic pressure |
| an average blood pressure reading | 120/80 |
| what factors can raise your blood pressure | size of arteries, volume, emotions & stress |
| hemoglobin (function) | carries O2 |
| RBC (function) | carries hemoglobin |
| WBC (function) | fights germs and bacteria |
| platelets (function) | forms clots |
| veins | bring blood to heart |
| arteries | carry blod from heart |
| capillaries | small tubes that connect veins and arteries |
| nasal cavity | filters, moisens, and warms incoming air (cillia filter) |
| trachea | tube that connectspharynx to bronchi |
| epiglottis | prevents food from going into trachea |
| bronchial tubes | primary: 2 main branches from the trachea that lead to lungs. secondary: smaller tubes that branch from each primary bronchi |
| alveoli | microscopic air sacs that exchange gases |
| capillaries | very small blood vessels that pick up O2 and give off CO2 with the alveoli |
| diaphragm | a muscular sheet that separates the abdominal and thoracic cavities |
| larynx | contains vocal cords that produce sound |
| pleural membrane | double membrane that surrounds each lung, protects and lubricates lungs |
| pneumonia | a virus or bacteria infects the walls of the alveoli causing them to swell. in the microscope you would see mucus in the alveoli |
| emphysema | pollutants dissolve alveoli walls, making less surface for gas exchange |
| bronchitis | (blank) |
| lung cancer | (blank) |
| inhalation | you take air into your lungs and your rib muscles contract, pulling ribs up and out. diaphragm contracts down |
| exhalation | you force air out of your lungs, your chest reduces in size, rib muscles relax down and diaphragm relaxes and moves up |
| pulmonary respiration | occurs at lungs, when O2 enters the blood and CO2 leaves blood |
| cellulary respiration | occurs in cells, uses O2 to break down glucose and obtain ATP energy inside the mitochondria |
| peristalsis | series of rhythmic contractions that digest food |
| vomiting | reverse peristalsis |
| diarrhea | when your colon doesn't remove juices that it should and excrement flows freely from the anus |
| heart attack | (blank) |
| gall stones | when a hard mass forms in the gall bladder, then tries to leave |
| heart burn | when the cardiac sphincter send back acid |
| parasitism | when one species feeds off another (the parasite gains and the host is harmed) |
| commensalism | when one species benefits and the other is neither harmed nor helped |
| herbivore | eats only plants |
| carnivore | eats only other animals |
| scavenger | feeds on the remains of other animals that it finds |
| decomposer | feed off and decomposes dead materials |
| omnivore | eats both plants and animals |
