Answer: Organism in this domain can be defined as living things that has an organized structure, and responds to stimuli, and has ability to reproduce, grow, and maintain a state of equilibrium. Organisms are of two types which are unicellular and multi cellular organisms.
Explanation: unicellular organisms are organisms that are made up of only one cell which carries out all the functions needed by the oragnism. Multicellular organisms are organisms that are made up of more than one cell. These organisms uses many different cells to function.
Unicellular organisms are often found in extreme environments such as hot springs, polar ice and frozen tundra.
Unicellular organisms have cell that contain a nucleus.
It is to help transport macromolecules back and forth between the nucleus and the cytoplasm. the nuclear pore complex also serves as a barrier between the cytoplasm and nucleus to prevent harm to genetic material housed in the nucleus :)
A protein channel is a transport protein that helps larger molecules, that would otherwise not be able to diffuse through the membrane of a cell to move in or out of the cell depending on the concentration gradient.
Answer:
Read the Explanation below.
Explanation:
They could first test the density of the skeleton to see if it is real or not (bone has a different density and weight than plastic). They could also measure a sample of one part of the skeleton and see if it contains skeletal tissue (if it does, it is a from a human being).
The lowest one would have the least amount of energy
