Tick all the scientists who did not make contribution to Biology.

This is a trick question...
There are many adapted cells such as the red [blank_start]blood[blank_end] cell and the root [blank_start]hair[blank_end] cell. The root [blank_start]hair[blank_end] cell has an increased [blank_start]area[blank_end] so that it can suck in more water. The red [blank_start]blood[blank_end] cell also has an increased [blank_start]area[blank_end], but this time it is for keeping [blank_start]haemoglobin[blank_end], which is the colour [blank_start]red[blank_end]. The body uses this to create oxygen.
Deoxyribonucleic acid's abbreviation is in this sentence as an anagram (and it is not all caps).
This text is about an average [blank_start]plant[blank_end] cell. It contains things such as [blank_start]chloroplast[blank_end] which turns energy into food and m[blank_start]itochond[blank_end]ria which produce the energy. This cell is surrounded by a cel[blank_start]l[blank_end] w[blank_start]all[blank_end], which gives the being a strong structure.
