Definition
a unit of hereditary transferred from parent to offspring. Defines some characteristics. Located In the DNA strands in the chromosomes.
Term
Define CHROMOSONEs and number of pairs
Definition
Chromosomes contain the coils of DNA. Humans have 23 pairs.
Term
Mitosis is...
Definition
Produces 2 genetically identical cells - diploid cells

Meiosis is...
Definition
Produces 4 sex gametes that have half the number of genes - haploid cells
Term
heterozygous is.....
homozygous is....
Definition
different alleles like Bb
the same alleles like BB or bb
Term
genotype and phenotype...
Definition
genotype is the gene makeup and phenotype is how the actual physical features look
Term
Selective breeding and an example
Definition
Breeding animals or plants for a specific trait. Belgian blues bred for a trait that causes excessive muscle growth
Term
describe the 4 molecules of dna and the structure

a chemical compound being broken down
Term
role of subscript numbers in chemical formulas
Definition
to balance the equation and it shows it in a stable state
Term
Define law of conservation of mass
Definition
mass can not be created or destroyed, it only rearranges
Term
define ACID, properties and examples, safety precautions
Definition
A corrosive or sour tasting liquid. Found in:
carbonated drinks (carbonic acid)
citrus fruits (citric acid)
vinegar (acetic acid)
milk (lactic acid)
Term
define BASIC, properties and examples, safety precautions
Definition
A bitter liquid that neutralises acids. Found in:

Term
acid and metal makes....
Definition
salt and hydrogen gas
Term
distance
Definition
the length of a space between two points
Term
instantaneous speed and average speed
Definition
- the actual speed at any given moment and - the average over time
Term
acceleration and deceleration
Definition
increasing speed and decreasing speed
Term
Newtons first law
Definition
Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
Term
newtons second law
Definition
The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.
Term
newtons third law
Definition
For every action there is an equal and opposite reaction.
Term
inertia
Definition
remaining unchanged until it is pushed by another force
Term
