where is the breakdown of protein | stomach |
what is a paradigm shift? | radical change from previous thinking |
adaptation | increase of alleles of certain genes from generation to generation that allows a species to survive and reproduce better |
natural selection | means by which adaptation occurs |
sympathetic nervous system | activates the body's fight-or-flight response |
quantitive data | numbers that can be measured |
biological classification system starts where | at the domain and becomes more specific as it descends to species |
water | has a high specific head and high heat of vaporization meaning that a great deal of energy is required to cause increases in temperature |
hydrocarbons with a double bond | CnH2n also known as alkenes |
hypothesis, or a claim | must be supported by analyzed data |
cardiovascular system's role | to provide the body's cells with oxygen and nutrients. but not primarily responsible for the transport |
after passing through the right ventricle of the heart during a contraction... | blood then travels through the tricuspid valve into pulmonary artery |
respiratory system | responsible for supplying the body with oxygen and removing carbon dioxide |
lining of hollow organs of the digestive system... | such as esophagus, stomach, and intestines, are comprised of smooth muscle tissue, which creates the peristalsis needed to push undigested food through the body |
protons | charge of 1+, mass = 2000 more massive than electrons |
electrons | charge of 1- |
spine | provide protection for spinal cord |
density | the higher the density, slower the travel |
acids | pH values of 1-7( 7 being neutral). so, a substance with a pH of 2 would be a strong acid |
immune cells are produced where | the body's bone marrow |
heart is located where | behind the sternum |
alveoli | structures in the respiratory system in which the exchange of gases occurs |
prokaryotic cell lacks what | a membrane-bound nucleus |
genotype | comprised of its various genes, which are made of DNA |
heterotrophs | mitochondria is the powerhouse of cells. |
what does the mitochondria produce for the cells | ATP |
ER | has ribosomes on surface giving it a rough characteristic |
genes | composed of DNA |
protein | composed of amino acids |
covalent bonds | require sharing of electrons |
ionic bonds | has electrons donated and accepted by atoms to complete the valence structure |
germ cells | only cell capable of passing along mutations of off spring |
DNA codons found in genes encode what | amino acids that make proteins |
what is the cell response cycle | DNA of cells should be fully and correctly duplicated |
what is only found in RNA | Uracil |
what is only found in DNA | thymine |
what is found in both DNA and RNA | guanine and adenine |
what does the mass number equal | the number of proteins and electrons |
heat removal equation | H= -ML |
where does meosis occur | only in germ cells |
where does mitosis occur | all other cells |
what is the number of protons equal to | the atomic number |
equation for saturated hydrocarbons | CnH2n+2 |
what does scientific research rely on | modern methods of data collection, display, and analysis |
what does collection involve | precise measuring tools |
what does display involve | 3D modeling with computer software |
what does analysis involve | high powered math |
what is a lysosome used for | required for waste processing because it contains the enzyme needed |
digestive system contains what | all organs from mouth to anus |
what do heterotrophs do | release CO2 |
what is CO2 used in heterotrophs | used to produce glucose in autotrophs during cellular respiration |
oxygen | by product of glucose production in autotrophs that is used by heterotrophs for ATP production in cellular respiration |
pancreas | component of endocrine system |
food processing | after food passes through the stomach, it goes into the duodenum |
Kenetic Energy equation | KE= 1/2MV^2= Joules |
alleles of genes | form from genetic changes (mutations) which can occur in genes. these mutations modify the gene and produce a different allele |
spindle fibers | grow from the centrosomes during mitosis to aid in chromosome separations |
colon | area for absorption of water |
