Biomolecules
lipids(fats)
another word for diversity, this is part of natural selection and can give you an advantage in survival
variation
Tt genotype
heterozygous
plant tissue that transports water from roots to leaves
xylem
Site of translation(protein synthesis)
ribosomes
these proteins catalyze chemical reactions, they have an active site and are specific to what they break down by their shape
enzymes
evidence of evolution- same structure, different function, ex. arm bones of various mammals
homologous structures
TT genotype
homozygous dominant
human body system that protects us rom the outside world, regulates our body temperature, skin
Integumentary System
Part of the cell cycle where DNA replicates
S phase
building blocks are made up of amino acids
proteins
evidence of evolution- structures at one time may have been useful in a common ancestor, but now have no function or limited function
vestigial structures
Each gene has at least 2 forms of these
Alleles
site in the male flower where pollen(sperm) is transferred
anther
type of cell transport that requires energy(ATP), molecules move from a low concentration to a higher concentration
active transport
CHON
protein
mechanism of evolution- when genes move from one population to another, increases variety
gene flow
Pink hair is dominant over green hair. Mom is heterozygous and dad is homozygous recessive. What is the expected phenotype?
50% Pink, 50% Green
works very closely with the nervous system to maintain homeostasis through the release of hormones
Endocrine System
phase of mitosis where chromosomes separate and move to opposite ends
anaphase
building blocks are nucleotides
nucleic acids
mechanism of evolution- change in gene pool caused by chance, tends to decrease a species' variation
genetic drift
mitosis occurs in what type of cells
somatic(body)
this organizational level comes before system
organ
transcribe ATTCAATAG
