# 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)
