TWO-POINT DISCRIMINATION TEST- the density of the touch receptors
varies in different areas of the body. Aras that have the greatest density of tactile
receptors have a height-ended ability to feel. Those areas correspond to areas
that receive the greates
NATURAL SELECTION & EVOLUTION- Nat.sel.is a mechanism of evolution,
is a process in which evolution happen, it is a process by which an individuals with
a certain heritable trait tend to produce more surviving offsprings. Evolutions is a

BIOLOGICALLY IMPORTANT FUNCTIONAL GROUPS(functional group-part of molecule that
determines the polarity and reactivity of the whole molecule): 1. Hydroxyl (OH)-makes alcohols, polar
because oxygen draws electrons to itself, attracts water molecules. E.g.

7.4, *carbonic acid- dissociates to bicarbonate ion (HCO3-) and H+, acid and base in equilibrium
with each other. H2CO3 <-> HCO3- +H+ ;*when blood pH goes up(basic)-H2CO
CHEMISTRY OF WATER:-about 75% Earths surface is covered with water; a cell contains
70-95% water; water is in 3 states of matter:solid, liquid, gas; a polar molecule-one molecule of
water can bond with up to 4 other molecules of water. PROPERTIES OF WATER
CHEMICAL BONDING-bonds between atoms are caused by electrons in outermost shells.
(covalent, ionic, hydrogen bonds). Molecule- two or more atoms bonded together. If all atoms in
molecule are of the same element- material is still called an element.eg.O2,
Cell wall (P)-gives support and shape to cell.
Chloroplast (P) makes food by photosynthesis; energy related organelle; double membrane; suspended in
semi-fluid stroma; green due to chlorophyll.
Plastids (P)-store food and pigment molecules.
