Natural selection is a mechanism for evolution. Those organisms best adapted to their environment are more likely to survive to reproductive age and pass on alleles for favourable characteristics to their offspring. In this case, the environment (nature) is doing the selecting.
Make a table to compare natural selection and artificial selection (include similarities as well as differences).
In the classification of T. aestivum and einkorn wheat, has the biological species concept or the cladistic concept been used?
The protein in wheat grains has a specific quality. When hydrated and kneaded it forms a sticky, rubbery mass that holds bubbles of gas produced from yeast, giving the characteristic light texture of bread. The only other cereal grain that produces a protein able to do this is rye.
Describe the nature and origin of the gas produced by yeast.
Explain why wheat flour used for bread-making needs to have a higher protein content than wheat flour used for making biscuits.
