Preap Biology Ch 1 Vocab

Carbohydrate – Compound made up of carbon, hydrogen, and oxygen atoms; CH2O; primary source of energy for the human body;
Monomers = monosaccharides
(Two indicators: Benedicts & Iodine)
pulmonary vein – from lungs to heart
Alternation of Generations – A life cycle in which there is both a multicellular diploid form, the sporophyte, and a multicellular haploid form
substrate – the reactant an enzyme acts on
Archegonia – a female reproductive structure producing gametes, occurring in ferns, mosses, fungi, and algae
adhesion – an attraction between molecules of different substances
exponential growth – population growth that is unhindered because of the abundance of resources for an ever-increasing population
Free energy – The portion of a system's energy that can perform work when temperature and pressure are uniform throughout the system.
Structure 15 on the diagram refers to
cancer – a disorder in which the cell is unable to control cell division
coenzyme – a cofactor which is organic
14.Lysosome – organelle that contains enzymes.
hypertonic solution – water exits the cell; cell shrinks
posterior – Pertaining to the rear, or tail, of a bilaterally symmetrical animal.
Replication fork – a site at which separation and replication of DNA occurs
Structure 15 оn the diаgrаm refers tо
Paleozoic era – There was extensive radiation of fish during the Devonian and Silurian periods within the Paleozoic Era.
Chromatin – Clusters of DNA, RNA, and proteins in the nucleus of a cell
Data – The observations, usually numerical, collected during an experiment and typically organized in a table.
RNA – Ribonucleic acid, a nucleic acid present in all living cells. Its principal role is the act as a messenger carrying instructions from DNA for controlling the synthesis of proteins. In some viruses, RNA rather than DNA carries the genetic information.
chemical reaction – Energy-requiring process by which atoms or groups of atoms are changed into different substances.
