Biologists use ball-and-stick models to study complex molecules by representing atoms with balls and bonds with sticks. dna is a biological molecule that contains millions of atoms. what is a limitation of using a ball-and-stick model for dna?
some kinds of atoms that are found in dna must be left out of the models.
dna has so many atoms that the size and cost of a model could be too great.
it is impossible to distinguish different kinds of atoms with models.
the chemical bonds between the atoms in dna must be part of the models.

Which best compares habitat and niche? o niche is a place in which organisms live, and habitat is the way in which an organism fits into its habitat. o habitat is a place in which organisms live, and niche is the way in which an organism fits into its habitat. habitat is a group of organisms that live in an area, and niche is a specific species that lives in that areao niche is a group of organisms that live in an area, and habitat is a specific species that lives in that area.

Osmosis is often viewed incorrectly as a process driven directly by differences in solute concentration across a selectively permeable membrane. what really drives osmosis? view available hint(s)osmosis is often viewed incorrectly as a process driven directly by differences in solute concentration across a selectively permeable membrane. what really drives osmosis? the first law of thermodynamicsthe difference in the height of water columns on either side of a selectively permeable membranethe difference in water concentration across a selectively permeable membranethe difference in sugar or ion concentration across a selectively permeable membrane
