The measure of the change in velocity
It is calculated by the change in velocity over time taken
What is acceleration
The larger the mass of an object, the more force is needed to accelerate it.
The larger the acceleration of a mass, the more force is needed to accelerate it.
Newtons second law
Some variations of inherited characteristics will increase the chances of an individual surviving in a particular environment
A spontaneous or induced change in the sequence of an organisms DNA and it occurs randomly
What is mutations
The study of fossils
What is palaentology
The change of position of an object in a straight line and its a vector quantity and the total length an object travels
What is displacement and distance
For every action there is an equal but opposite force
Newtons third law
Members with the most favourable traits have an increased chance of survival
What is the second stage of natural selection
Refers to the movement of individuals from one population to another and it is also known as migration
What is gene flow
The study of the structure of organs and limbs of different organisms, includes analogous and homologous structures
What is comparative anatomy
A measure of how fast something travels, but it must have a direction and is calculated by displacement over time taken
What is velocity
What are the types of chemical reactions
Surviving members have increased chance of reproducing and passing these traits on
What is the third stage of natural selection
Relates to genetic changes that typically occur by chance as a result of catastrophic event
What is genetic drift
The study of the development of the embryo of different organisms
What is comparative embryology
An object remains at rest or in motion unless acted on by an unbalanced force
What is newtons first law
Atoms cannot be created or destroyed
What is the law of conservation of mass
Over time organisms will possess the traits that make them better suited to their environment, therefore increasing their chance of survival
What is the fourth stage of natural selection
A special feature or characteristic that improves an organisms chance of survival in their environment, the three types are structural, behavioural, and physiological
What are adaptations
The sequencing of DNA to compare genetic relationships between organisms
What is molecular biology
The resistance of an object to any changes in its velocity
Inertia
Temperature, concentration, surface area, pressure
What are factors that affect the rate of reaction
Determines which variations provide better chances of survival to certain individuals and can be biotic or abiotic
What is selection pressures
Includes the process of ‘crossing over’ during meiosis, and the random combination of genetic information from 2 parents
What is sexual reproduction
Comparing the biochemical make-up (such as amino acids and proteins) of organisms
What is biochemistry
