Talons and gills
What are adaptation and examples
Adaptations are passed down from generation to generation.
Adaptations aid the organism in its survival.
There are three types of adaptations:
Structural adaptations
Physiological adaptations
Behavioural adaptations
What are Structural adaptation?
Structural adaptations are related to the physical appearance of an organism.
what are Physiological adaptations and examples
Physiological adaptations are related to the organism’s internal organs.
Examples of physiological adaptations include:
Major organs such as the heart (to pump blood) or stomach (to digest cellulose)
The production of hormones and enzymes
What are Behavioural adaptations and examples
Behavioural adaptations are the response an organism has when it survives.
Behavioural adaptations include:
Octopuses can change shape and colour
Gull chicks peck at the red dot on their parent’s beak to get food

What does pure substances mean?
we mean substances that contain only one element or compound.
What happens if a substance contains impurities?
If a substance contains ‘impurities’, it does not contain only one element or compound.
Pure substances melt or boil at …
Pure substances melt or boil at sharp temperatures
A single element or compound that has exact and specific melting and boiling points.
Pure substance
If these are present in a sample, they will lower the melting point and widen the range of temperatures at which the sample will melt.
Impurities
The closer the experimentally recorded melting or boiling points are to those found in the data book, the greater the ____ of a sample.
The closer the experimentally recorded melting or boiling points are to those found in the data book, the greater the purity of a sample.
How do impurities affect the melting point of a sample?
Reduce the accuracy of the melting point
What do pure substances contain
Pure substances only contain one type of atom, element or compound.
Impure substances contain other _____.
Impure substances are a ____.
Impure substances contain other atoms.
Impure substances are a mixture.
What happens if a substance contains impurities
If a substance contains impurities, the boiling or melting point will change.
Which of these are aspects of a pure substance?
