ATI TEAS 7 SCIENCE DEFINATION OF TERMS AS ACCURATE
ANSWERS
Central Nervous System - Accurate answers Part of the nervous system that releases chemicals to
regulate the pituitary gland.
Sarcomere Shortening - Accurate answers Directly due to the interaction of myosin and actin in
skeletal muscle.
Inherited Mutations - Accurate answers Can occur in ovarian, endocrine, neural, or muscle cells
and be passed to offspring.
Tendon Function - Accurate answers Attaches skeletal muscle to bone, not bones to ligaments or
muscles to ligaments.
Urea Excretion - Accurate answers Substance excreted by sweat glands in response to protein
breakdown and ammonia formation.
Excretion - Accurate answers Describes the removal of metabolic waste from the body.
Hypertonic Solution Osmosis - Accurate answers Results in a net flow of water out of the cell.
Active Transport Example - Accurate answers Movement of sodium and potassium across the cell
membrane against their concentration gradient.
Superior Vena Cava - Accurate answers Vessel responsible for carrying blood from the upper body
to the right atrium of the heart.
Carbohydrate Composition - Accurate answers Composed of monosaccharides, not nucleic acids,
isoprenoids, or amino acids.
Carbonic Acid-Bicarbonate Ion Buffer System - Accurate answers Maintains blood pH balance, with
specific reactions for excessive H+ ions.
Photosynthesis Wavelengths - Accurate answers Different wavelengths affect photosynthesis
differently, with IR containing more energy.
Correlational Study Weakness - Accurate answers Cannot determine causation, as it only shows
relationships between variables.
Vasectomy Infertility - Accurate answers Leads to infertility by blocking the movement of sperm
from the epididymis into the urethra.
Active Immunity - Accurate answers Provides lifelong protection after exposure to specific
pathogens.
, Gas Volume - Accurate answers Equal mass of gas can fill different containers, unlike solids or
liquids.
Carbon Isotope C-12 - Accurate answers Possesses 6 neutrons and 6 protons in its nucleus.
Spinal Cord Tissue Damage - Accurate answers Permanent damage to nervous tissue in the spinal
cord causes paralysis.
Mass Indication Unit - Accurate answers Mass is indicated in mg, not cm3, ml, or irm.
Histones - Accurate answers Proteins associated with DNA, not blood, sperm cells, or hair follicles.
Pancreatic Secretion for Starch Digestion - Accurate answers Amylase digests starch into
disaccharides, not trypsin, chymotrypsin, or lipase.
Blood Pathway - Accurate answers Blood flows from the right atrium to the right ventricle, then to
the pulmonic valve, pulmonary artery, and lungs.
Hydrophilic Hormone Action - Accurate answers Binds to cell-surface receptors of the target cells
to activate them.
Water Property - Accurate answers Dissolves polar ionic compounds, not made of one molecule of
hydrogen and two molecules of oxygen.
Atomic Number and Mass - Accurate answers Lithium has an atomic number of 3 and a mass of 7,
not 12, 4, or 144.
Viral DNA Insertion - Accurate answers Reverse transcriptase, an enzyme encoded by the virus,
allows the AIDS virus to insert viral DNA into the DNA of a host T-cells.
Complementary DNA Strand - Accurate answers If a portion of a DNA strand reads 5'AGCTAGCGT
3', the complementary strand reads 3'TCGATCGCA5'.
Carbon Dioxide Movement - Accurate answers Most of the carbon dioxide from the blood moves
into alveoli through diffusion down a concentration gradient.
Tendon Function - Accurate answers Attaches skeletal muscles to bones, not bones to ligaments or
muscles to ligaments.
Excretion - Accurate answers Describes the removal of metabolic waste from the body.
Blood Pathway - Accurate answers Blood flows from the right atrium to the right ventricle, then to
the pulmonic valve, pulmonary artery, and lungs.
Vasectomy Infertility - Accurate answers Leads to infertility by blocking the movement of sperm
from the epididymis into the urethra.
