Which homeostatic process requires energy to move particles across the plasma membrane?
1.active transport
2.passive transport
3.dynamic equilibrium
4.osmosis

The right answer is 1. active transport.

Active transport refers to the passage of an ion or molecule across a membrane against its concentration gradient.

If the process uses chemical energy produced, for example, by the hydrolysis of a nucleotide triphosphate such as adenosine triphosphate, it is called primary active transport.

Active transport is opposed to passive transport, which does not use energy.

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.
