Hydrogen Bonding between molecules.
- High specific heat
s or water stabilize climates
- Strong cohesive and adhesive properties
- Water freezes forms a lattice crystal resulting in ice floating in water.
- Polarity of water allows it to act as a universal solvent.
- Water can be used to dissolve different solvents.
Carbohydrates - CORRECT ANSWER-Long chains, or polymers of sugar. Most
importantly form the backbone of DNA and RNA.
Saturated - CORRECT ANSWER-Clogs arteries. NO DOUBLE BONDS in their
hydrocarbon tail. SOLID @ room temperature.
Unsaturated - CORRECT ANSWER-Double bond in their hydrocarbon tail. LIQUID at
room temperature.
Hierarchic Organizational system for nomenclature - CORRECT ANSWER-Kingdom
Phylum
Class
Order
Family
Genus
Species (Least)
"Keep Penguins Cool Or Find Good Shelter"
Scientific Method - CORRECT ANSWER-Observation
Hypothesis
Experiment
Conclusion
Water - CORRECT ANSWER-All life, and therefore biology , occurs in water.
Properties of Water - CORRECT ANSWER-2 Hydrogen bonds Covalently bonded to
Oxygen.
, Phospholipids - CORRECT ANSWER-Phosphate group (polar) soluble in water.
Hydrocarbon tail of fatty acids is nonpolar and nonsoluble in water.
Ex. Cell Membrane
Steroids - CORRECT ANSWER-Are lipids, which are precursors to hormones and
drugs
Proteins - CORRECT ANSWER-They are Polymers of 20 molecules called Amino
Acids. Enzymes are a type of protein, which catalyze different reactions or processes.
LARGEST Biological Molecule
Cell - CORRECT ANSWER-Fundamental unit of biology
Prokaryotic Cells - CORRECT ANSWER-NO defined nucleus and NO membrane-
bound organelles.
Eukaryotic Cells - CORRECT ANSWER-Membrane-enclosed nucleus and series of
membrane-bound organelles that carry out the functions of the cell as directed by the
genetic information contained in the nucleus.
Nucleus - CORRECT ANSWER-Contains DNA called Chromosomes.
Ribosomes - CORRECT ANSWER-Are organelles that read the RNA produced in the
nucleus and TRANSLATE the genetic instructions to produce PROTEINS.
Bound ribosomes - CORRECT ANSWER-Are found attached to the endoplasmic
reticulum (ER)
Free ribosomes - CORRECT ANSWER-Are found in the cytoplasm
Endoplasmic reticulum - CORRECT ANSWER-Attached to the nucleur membrane and
consists of two continuous parts.
Rough ER - CORRECT ANSWER-Covered in RIBOSOMES and is responsible for
PROTEIN SYNTHESIS and membrane production.
Smooth ER - CORRECT ANSWER-NO ribosomes. It functions in the DETOXification
and METABOLISM of multiple molecules.
Golgi Apparatus - CORRECT ANSWER-Packaging, processing and shipping. "UPS"
