What do they all have in common?

1. What do they all have in common?

4. Comparing living things and nonliving things Do all living things share certain characteristics? If so, what are those traits or characteristics? In groups, make up a table that has one column with the heading TRAITS. Then, in your group, decide what are the traits that all living things share. (between 5-10) Put those traits under your column heading. The group then examines each of the specimens and decides whether it has the trait or not. Explain why in bullet point form. You can disagree with your group, just explain why Once you have finished all the samples, analyze your data by explaining, in sentence form, what your results appear to show.

10. If you are in good health and averagely diligent about hygiene, you will have a herd of about one trillion bacteria grazing on your fleshy plains – about a hundred thousand of them on every square centimetre of skin.

11. There are trillions more tucked away in your gut and nasal passages, clinging to your hair and eyelashes, swimming over the surface of your eyes and drilling through the enamel of your teeth. Your digestive system alone is host to more than a hundred trillion microbes, of at least four hundred types The body consists of ten quadrillion cells but is host to about a hundred quadrillion bacterial cells.
