15. which of the following statements is best
supported by the information in the graph?
o a. pebbles are able to be moved at slower
stream velocities than silt particles.
o b. streams are only able to move particles
less than 1 cm in diameter, and all other particle
sizes can only be moved in rivers.
o c. particle diameter controls stream velocity
across all scales.
o d. small increases in stream velocity can lead
to many changes in particle size at slower
velocities, but changes in larger particle sizes
require more significant changes at higher
velocities.

where is the option.let me know

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
