PAPER SOLVED ITEMS ACCURATE MARKING
◉ Atom. Answer: smallest unit of matter that still retains the
properties of an element.
◉ Element. Answer: a substance that cannot be broken down to
other substances by chemical reactions.
◉ matter. Answer: anything that takes up space and has mass
◉ cell. Answer: ___ is the basic unit of structure and function in an
organism.
◉ Neutrons. Answer: no charge (in nucleus)
◉ Electrons. Answer: negative charge (form a cloud around nucleus)
◉ First shell of table. Answer: 2 e-
◉ Second shell of table. Answer: 8 e-
,◉ Third shell of table. Answer: 8 e-
◉ Isotopes. Answer: two atoms of an element that differ in the
amount of neutrons
◉ electronegativity. Answer: describes an atoms attraction for
electrons
◉ RNA; protein. Answer: central dogma: DNA is transcribed into
______ then translated into a ______.
◉ Eukaryotic; prokaryotic. Answer: a _____ cell has membrane-
enclosed organelles while a _____ cell is simpler, usually smaller; and
does not contain any membrane-enclosed organelles.
◉ valence electrons. Answer: those electrons that are found in the
outermost shell/valence shell. Chemical behavior is determined by
_____ ______.
◉ the more electronegative an atom. Answer: the more strongly it
pulls shared electrons toward itself.
◉ covalent bonds. Answer: the sharing of a pair of valence electrons
by two atoms
,◉ non-polar. Answer: e- are evenly shared
◉ polar. Answer: e- are unevenly shared (H20 is a polar molecule)
◉ ionic bond. Answer: an attraction between an anion and a cation
◉ cation. Answer: positively charged ion
◉ anion. Answer: negatively charged ion
◉ hydrogen, oxygen, carbon and nitrogen. Answer: What are the
four elements that make up 96% of living matter?
◉ Hydrogen bonding. Answer: when a hydrogen atom covalently
bonded to one electronegative atom is also attracted to another
electronegative atom.
◉ Water. Answer: the medium of life
◉ What are the three phases of water?. Answer: Solid, liquid and gas.
, ◉ cohesion. Answer: hydrogen bonds hold water molecules together.
This phenomenon is responsible for the transport of water against
gravity in plants.
◉ adhesion. Answer: an attraction between water and different
substances, for example between water and plant cell walls.
◉ surface tension. Answer: a measure of how hard it is to break the
surface of a liquid.
◉ What are the five emergent properties of water?
1. Cohesion and adhesion
2. Ability to moderate temperatures
3. Evaporative cooling
4.Expansion upon freezing/insulation of bodies of water.
5. Universal solvent. Answer: What are the five emergent properties
of water?
◉ 104.5. Answer: what is the bond angle of water?
◉ Evaporation. Answer: transformation of a substance from liquid to
gas
