 78 | # of chromosomes Barbie the chicken has in her body cells |
| 39 | # of chromosomes Barbie the chicken has in her egg cells |
| 39 | # of chromosomes Barbie the chicken has in her zygote |
| mitochondria | provides energy for an organism |
| epiglottis | prevents food and liquid from entering the lungs |
| animalia | kingdom which consists of multicellular organisms; cells have nuclei and are consumers (heterotrophs) |
| biotic factor | living, alive; e.g: plants, animals, worms, bacteria, goldfish, Barbie Q the chicken, turtles, etc... |
| Plantae | kingdom having multicellular organisms, cell walls, does not one, contains chloroplasts therefore it produces its own food (chlorophyll/sugar) |
| homozygous | have identical alleles for a single trait |
| caryotyping | is the study of chromosomes (male/female) |
| nerve tissue | carries electrical impulses via the neurons or nerve cell to the brain |
| alveoli | exchanges gases in the ungs |
| law of dominants | (Mendel) one allele is expressed or dominant while the other is hidden or recessive |
| Protista | can be heterotropic (cannot make its own food), or auto tropic (makes its own food - green plants); most live in water , are eukaryotic, they move using cilia |
| testes | produces sperm cells (in mates) necessary for meiosis (they contain HALF the genetic material) |
| bronchial tubes | caarries air into the lungs |
| muscle tissue | functions in movement; gives off heat when you exercise strenuously; muscles seem to burn during a tough workout |
| Mendel | studied inherited (genetic) traits using pen plants |
| law of segregation | (Mendel) single gamete (sex cells) has half the original amount of chromosomes |
| blood platelets | are mainly responsible for blood clotting and plasma does help some also |
| heterozygous | two different alleles for a single trait |
| Taysachs hemophylia | are serious inherited diseases; one attacks the nervous system, (Taysachs) the other is a bleeding disorder (platelets) cannot clot the blood |
| abiotic factors | not alive, non-living e.g.: rocks, dirt, air, minerals, clouds, water, temperatures, glass, mountains |
| digestive system | not present in plants because plants can make their own food (auto tropic) whereas animals need to break their food down |
| epithelial tissue | functions as boundary tissue |
| connective tissue | holds body parts together |
| fungi | are decomposers, heterotrophs (cannot make their own food), mushrooms, molds, yeasts |
| vacuoles | can change cell size in plants - can fill up to 90% of inner cell space; store water, waste, food |
| ovary | produces egg cels (in females) necessary for meiosis (they contain HALF the genetic material) |
