Tumors - ANS-unregulated cell division forming a lump of cells with no function
How does ATP provide energy for a cell - ANS-Loses a phosphate group
Metabolic taxicab shuttles electrons - ANS-NADH
Which process will follow glycolysis if oxygen is not available - ANS-fermentation
Which chloroplast structure increases the amount of surface area - ANS-Thylakoid
First step of photosynthesis - ANS-light reactions
What energy molecule is produced during light reactions - ANS-ATP
Which process provides cO2 you exhale - ANS-aerobic respiration
What is the region in the middle of replicate chromosome - ANS-Centromere
Which part of mitosis does the nuclear envelope break down - ANS-Prophase
Which process does a cell plate form - ANS-Cytokinesis in a plant cell
In which phase of the cell cycle are cells most often found - ANS-Interphase
When do sister chromatids separate - ANS-meiosis II and mitosis
Which describes heat - ANS-Total amount of energy associated with the movement of
molecules
metastasis - ANS-cells break away from a malignant tumor and start new cancers at distant
locations
Carried in genes - ANS-Inherited cancer risk
Environmental exposures - ANS-Exposure to carcinogens (cancer-causing agents)
Synergistic risk factors - ANS-enhance the activity of other carcinogens
Two types of reproduction - ANS-asexual and sexual
, asexual reproduction - ANS-A reproductive process that involves only one parent and produces
offspring that are identical to the parent.
sexual reproduction - ANS-A reproductive process that involves two parents that combine their
genetic material to produce a new organism, which differs from both parents
Gametes - ANS-reproductive cells
Genes - ANS-section of DNA with instructions for building all cell proteins
Prophase II - ANS-The duplicated chromosomes and spindle fibers reappear in each new cell.
Metaphase II - ANS-Chromosomes line up in the middle again
Anaphase II - ANS-sister chromatids separate
Telophase II - ANS-Nuclear membrane reforms, cytoplasm divides, 4 daughter cells formed
Chromosomes - ANS-made of DNA wrapped around proteins
sister chromatids - ANS-duplicated chromosomes, attached at the centromere
greenhouse effect - ANS-Natural situation in which heat is retained in Earth's atmosphere by
carbon dioxide, methane, water vapor, and other gases
What are the sides of the DNA ladder made of? - ANS-sugar and phosphate
What are the rings of the DNA ladder made of? - ANS-nitrogen bases
Adenine pairs with - ANS-Thymine (T)
Thymine pairs with - ANS-Adenine (A)
Cytosine pairs with - ANS-Guanine (G)
Guanine pairs with - ANS-Cytosine (C)
When does DNA replication occur? - ANS-before cell division
semiconservative replication - ANS-Newly formed DNA strand has one-half new daughter DNA
and one-half conserved parental DNA
DNA polymerase - ANS-enzyme that replicates DNA and moves along the unwound DNA to
form new strands
