The relevance and promise of
biological science
 Biology attempts to give scientific answers
to many questions that most people think are
important. These are
 Where did humans come from?
 Where did I come from?
 How do I work?
 How did all life begin?
 How is disease caused? And so on
cont’
• Biologists try to find possible biological explanations
for other non-scientific aspects of life:– Have a strong religious belief whilst other don’t
– have amazing musical talent, whilst other don’t
– can write poetry, whilst others can’t
Biology and agriculture
• Biologists are carrying out research
into how to produce crop plants that:
–will be adapted to the new
conditions
– are disease resistant
– are drought resistant
Biology and medicine
• Biologists are also closely involved in medical
work
– medical lab technicians who test b|d
samples and other samples and provide
reports for dr
– Radiographers, who produce X-rays and
other images to help in the diagnosis of
disease
– specialized researchers who look into why
and how cancer is caused.
Biology and the environment
• Biologists are actively involved in monitoring
the impact of global warming on the
environment
 Biotechnology is an exciting area of
biological research that is expanding rapidly.
The promise of research in these fields is huge.
Among the goals are;
- cures for genetic diseases
- producing drugs that are ‘tailor-made’
Cont’
• Cloning of productive animals and plants
• Producing antibodies that can deliver
drug to cells
