# 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)
