Practise Edexcel IGCSE Biology safe experimental methods by explaining apparatus functions, safety precautions and steps that keep tests valid.
Scientists have genetically modified soya plants so that the soya beans they produce contain less saturated fat.
The scientists produced one transgenic soya plant. Micropropagation was then used to make multiple copies of this transgenic soya plant.
A student uses this equipment to compare the energy content of transgenic soya beans with the energy content of non-transgenic soya beans.
Give one safety precaution that the student should take when using the apparatus.
