# of chromosomes Barbie the chicken has in her body cells


# of chromosomes Barbie the chicken has in her egg cells


# of chromosomes Barbie the chicken has in her zygote


provides energy for an organism


prevents food and liquid from entering the lungs


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...


kingdom having multicellular organisms, cell walls, does not one, contains chloroplasts therefore it produces its own food (chlorophyll/sugar)


have identical alleles for a single trait


is the study of chromosomes (male/female)

nerve tissue

carries electrical impulses via the neurons or nerve cell to the brain


exchanges gases in the ungs

law of dominants

(Mendel) one allele is expressed or dominant while the other is hidden or recessive


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


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


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


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


are decomposers, heterotrophs (cannot make their own food), mushrooms, molds, yeasts


can change cell size in plants - can fill up to 90% of inner cell space; store water, waste, food


produces egg cels (in females) necessary for meiosis (they contain HALF the genetic material)
