Sample Question
Describe the features of a homologous series.

Homologous series do not exhibit any similarities in chemical properties and physical properties.

Include the same general formula, neighbouring members differing by CH2, similar chemical properties and gradation in physical properties. Homologous series: A series of compounds (usually hydrocarbons) that display similar chemical properties and functional groups but different physical properties (generally boiling point), often differing by one repeating unit, usually a CH2/CH3 molecule. They can be given a general formula, eg CnH2n+2 Organic chemistry is the chemistry of carbon compounds (excluding compounds such as metal carbonates and oxides). The ability of carbon atoms to form chains leads to the existence of a series of compounds that have the same functional group (and hence similar chemical properties) and only differ from each other by the presence of an additional carbon atom and its two associated hydrogen atoms in the molecule (which causes the physical properties to change in a regular manner).

Homologous series do not have a general formula and do not show gradation in physical properties.

Homologous series consist of compounds that have completely different chemical properties and functional groups.

Sample Question
State the independence of the vertical and the horizontal components of velocity for a projectile in a uniform field.

The vertical and horizontal components of velocity for a projectile in a uniform field are directly proportional to each other.

The vertical and horizontal components of velocity for a projectile in a uniform field are inversely proportional to each other.

Simple state objective.

The vertical and horizontal components of velocity for a projectile in a uniform field are dependent on the projectile's mass.

Sample Question
What is the body design of sponges?

Bilateral body symmetry with highly specialized organs for locomotion and digestion.

Mobile organisms capable of rapid movement and hunting for prey in a coordinated manner.

Uniquely multicellular body specialized for filter feeding, by separating of suspended food particles from water by passing them through a mesh that strains out the food,Dynamic ameboid movement of cells in tissue and totipotent cells that allow for dynamic change in body structure.This suggests that sponges are an intermediate form between protozoans and other metazoans in which tissues and cells are more permanently specialized.Porous and allows water to pass through body and absorbs food.Sessile and attached organisms, although some have limited movementBody symmetry may be radial (sphere, cone, or cylinder), but asymmetry predominates. Indeterminate Growth

Solid body structure with no openings for water flow and food absorption.
