What is a similarity between all bacteria and plants? a. they both have a nucleus b. they are both composed of cells c. they both have chloroplasts d. they both lack a cell wall?

The correct answer is b.they are both composed of cells

Explanation:

Both bacteria and plants are composed of cells. Bacteria is a single cellular organism so it is composed of only one cell while plants are multicellular organism, therefore, it is composed of many cells.

Bacteria are prokaryotes so bacterial cells do not contain a membrane-bound nucleus and other membrane bound organelle but plants are eukaryotes so they have a membrane-bound nucleus and other membrane-bound organelle.

Both bacteria and plant cells have cell wall outside their cell membrane. Plant cell wall is made up of cellulose which bacterial cell wall is made up of peptidoglycan of lipopolysaccharide.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
