Apologia Biology Module 6 2nd Edition

lysosome – the organelle in animal cells responsible for hydrolysis reactions that break down proteins, polysaccharides, disaccharides, and some lipids
directional selection – form of natural selection in which the entire curve moves; occurs when individuals at one end of a distribution curve have higher fitness than individuals in the middle or at the other end of the curve
Middle Lamella – The thin film between the cell walls of adjacent plant cells
Hypertonic – HYPER = hyperactive (MORE activity)
TONIC = solution
When there is MORE solute in the SOLUTION than in the cell.
solution – another name for a homogeneous mixture (has a uniform composition throughout).
The spinal head – What structure is the main axis of the human nervous system?
The term blepharitis means inflammation
Hydrophilic – Attracts water molecules
80. skin cells – tough, thin, flat, specialized to protect the body
Where are the only places that cell division occurs in plants, what are these places called? – These are places called meristems and they're at the tips and the roots.
lipid – a class of biomolecules insoluble in water and usually made up of fatty acids; make up cell membranes; used by cells for long-term energy storage; examples are fats, oils, waxes, and steroids
base – compound that produces hydroxide ions (OH-) in solution
Convergent evolution – Process by which unrelated organisms independently evolve similarities when adapting to similar environments (shows the effect of environmental conditions on evolution, NOT that they are closely related). Example: whales and dolphins (mammals) and fish both developed streamlined bodies and fins independently of each other.
A species role in the food chain is part of its – niche
The term blephаritis meаns inflаmmatiоn
Mutualism – Symbiotic relationship where both organisms benefit
Cytoplasm – region of the cell that is within the plasma membrane and that includes the fluid, the cytoskeleton, and all of the organelles except the nucleus
mRNA (messenger RNA) – RNA molecule that carries copies of instructions for the assembly of amino acids into proteins from DNA to the rest of the cell
replication – the action or process of reproducing or duplicating
transformation – process in which one strain of bacteria is changed by a gene or genes from another strain of bacteria
