Answer;
-It belongs to Domain archaea
Explanation;
-Domain Archaea is any of a group of single-celled prokaryotic organisms (organisms whose cells lack a defined nucleus) that have distinct molecular characteristics separating them from bacteria as well as from eukaryotes.
-Eukaryote and archaea (ancient bacteria) both have DNA wrapped around histones to form chromatin.
-Eubacterium (true bacteria) do not contain histones.
-Eukaryotes have multiple linear chromosomes while archaea have a single circular chromosome.
They exhibit considerable molecular complexity and diversity
You must pack food that has high concentrations of fat and protein. Food like granola bars and canned meat are a good source of energy and heat. This is because the body breaks this food down easily converting it into usable energy. Though some people would suggest that you pack food that are high in carbohydrates, fats and proteins are long-term sources of energy that you would need for your hiking trip.
