questions with solutions
Strengths of Science - --publicly understandable
- self correcting
- predictive
-Qualities of Life - -- organized
- acquire material and energy
- reproduce
- respond to stimuli
- homeostatic
- grow and develop
- capacity to adapt
-2 main components of viruses - --capsid
- nucleic acid core (DNA or RNA)
-Virus life cycle - -Attachment
Entry
Replication
Biosynthesis
Assemble
Budding/Emergence
Repeat/Release?
-Life on earth has changed - -Law (describes)
-Things fall due to orbit - -Theory (explains)
-All mammals have mammary glands, therefore humans are mammals... - -Deductive
reasoning
-Inductive reasoning - -specific to general
-Deductive reasoning - -general to specific
-Covalent bonding - -SHARING of Electrons!
polar= unequal
non-polar= equal
-Ionic bonds - -transfer electrons
Na- donor
Cl- acceptor
, -Hydrogen bonds - -Weak individually, but strong together
(F) (O) (N)
-Acid solutions - -high concentration of Hydrogen ions
-pH of 0-6
-X-axis - -experimental variable (time)
-Y-axis - -dependent (result)
-Challenges for Science - --Loss of Diversity
-Emerging/Reemerging Diseases
-Climate Change
-Properties of H2O due to Hydrogen Bonds - -- high heat capacity (doesn't change temp.
easy)
- High heat vaporization (cooling)
-dissolves in many molecules (hydrophobic/phillic)
-Cohesion - -water molecules cling together.
-Adhesion - -water adheres to polar surfaces b/c of - & + poles
-Basic solutions - -Low concentration of H+
- pH of 8-14
-Functional groups - -specific combination of bonded atoms that REACT the SAME
-Hydroxyl
-Amino
- Methyl
-Organic molecules always have: - -Carbon and Hydrogen
-Amino group - --NH2 (Amine)
-Hydroxyl group - --OH (Alcohol)
-Methyl group - -Methylated group
-Hydrolysis - -Breaking of water, water added
-reaction to degrade polymers
-Dehydration reaction - -an -OH and -H removed as a water molecule
-Carbohydrates - -short term energy storage, fuel.
