Ascientist sketches bacteria observed in different samples.

which question is the scientist most likely trying to answer about the bacteria?

what methods of reproduction do they use?
how large is the nucleus in each bacterium?
which types of bacterium are in each sample?
how many cells make up each bacterium?

Ans.

Bacteria are unicellular, prokaryotic organisms, which belong to kingdom Monera. Bacteria exhibit a wide variety of shape and size and can be classified according to their shapes, such as rod-shaped, spherical, comma, spiral or corkscrew.

The diagram represents different bacterial cells with different size and shape. The light-green bacterial cells represent rod-shaped bacteria, the pink bacteria represent spiral bacteria, and the dark-green bacteria represent spherical bacteria.

Thus, the correct answer is 'option). which types of bacterium are in each sample?'

as many times as you want

the answer is c.) there is a warm front in region a and a stationary front in region b.
