Biology Apologia Exploring Creation With Biology Module 1 2nd Edition

adrenal medulla – The inner region of the adrenal gland, which works which the sympathetic nervous system to prepare the body to react in stressful situations.
Exocytosis – a process in which a vesicle inside the cell fuses with the cell membrane and releases its contents into the external environment
start codon – On mRNA, the specific three-nucleotide sequence (AUG) to which an initiator tRNA molecule binds, starting translation of genetic information.
pH Scale – A system of measurement that tells (indicates) the concentration of H+ ions in a solution.
Virus – A nonliving structure, composed of a nucleic acid and a protein coat, that invades living cells, takes them over, and tricks them into make more viruses, causing cell death
bilateral symmetry – An arrangement of body parts such that an organism can be divided equally by a single cut passing longitudinally through it. A bilaterally symmetrical organism has mirror-image right and left sides.
solution – mixture of two or more substances in which the molecules of the substances are evenly distributed
Thylakoids – A flattened, membranous sac inside a chloroplast. Thylakoids often exist in stacks called grana that are interconnected; their membranes contain molecular "machinery" used to convert light energy to chemical energy.
inhibit – products _____ allosteric enzymes
excision of a lobe (of the lungs)
3.4.1 Explain DNA replication in terms of unwinding of the double helix and separation of the strands by helicase, followed by the formation of the new complementary strands by DNA polymerase – helix is unwound; two strands are separated; helicase (is the enzyme that unwinds the helix separating the two strands); by breaking hydrogen bonds between bases; new strands formed on each of the two single strands;
nucleotides added to form new strands; complementary base pairing;
A to T and G to C; DNA polymerase forms the new complementary strands; replication is semi-conservative; each of the DNA molecules formed has one old and one new strand;
epithelium – animal tissue consisting of one or more layers of cells that have only one free surface, because the other surface adheres to a membrane or other substance
Aquaporin – Water channel protein in a cell
Telophase – what stage is this?
Protein – Organic compound made of amino acids joined by peptide bonds; primary building block of organisms.
Mitochondrion – Convert chemical energy stored in food into useable energy (ATP)
Often times referred to as the powerhouse of the cell.
excisiоn оf а lоbe (of the lungs)
exergonic – products have less energy than reactants
bottleneck effect – Genetic drift resulting from the reduction of a population, typically by a natural disaster, such that the surviving population is no longer genetically representative of the original population.
