A cell nucleus contains 46 Chromosomes, which carry genes and are made of DNA. Different versions of genes are called alleles.
Transpiration is the loss of water from the leaves

HSW Word
Definition
Hypothesis
A possible explanation of a problem that can be tested experimentally.
Evidence
The data or observations that are used to support a given hypothesis or belief.
Theory
An idea that might explain the results which is based on scientific results.
Hearsay
A rumour or idea with no evidence to back it up.
Control
A experiment to show what would have happened if you had not changed the independent variable.
Precision
Small divisions on the measuring device gives high precision.
Accuracy
An accurate measurement is one which is close to the true value.
Reliability
The results of an investigation may be considered reliable if they can be repeated.
Ethical
Whether something is considered morally right or wrong.
Validity
Valid data answers the question asked by the investigation. Data are only valid if the experiment is a fair test.
