What is the difference between arbitrary and natural levels? Why do these matter? (4) how do archaeologists recover the smallest

artifacts and ecofacts?

Vlada [557]3 years ago

Arbitrary level refers to the fundamental vertical subdivision of an excavation square, implied only when easily identifiable natural strata are absent and when natural strata are more than ten centimeters thick.  

Natural strata refer to a vertical subdivision of an excavation square, which is reliant on the natural breaks in the sediments in terms of grain size, color, hardness, texture, or other features.  

It is important to know the difference between the arbitrary and natural levels as arbitrary levels could amalgamate artifacts from distinct natural levels, that is, of distinct geologic contexts.  

The archaeologists can recover the smallest ecofacts and artifacts with the assistance of flotation, screening, and bulk matrix processing

You can recognize the process of pinocytosis when THE CELL IS ENGULFING EXTRACELLULAR FLUID.
Pinocytosis is one of the forms of endocytosis; it involves the movement of large particle into the cell by an in-folding of the plasma membrane. It is an active form of transport used to move materials into the cells.

You are operating a powerboat at night. Your red sidelight must be visible to boats approaching from which direction(s)?
Degger [83]
I believe the answer is head-on and port (left). The side lights are usually visible to vessels approaching from the front or the side. The red light usually indicates a vessel's port (left) side while the green light indicates a vessel's starboard (right) side. These lights ensure that there is safety at night as the vessels navigate.

Why is the archaea domain closer to eukarya than bacteria?
harkovskaia [24]

Answer:

Archaea domain is closer to eukarya than bacteria because genetically they are more similar to Eukarya than Bacteria.

Explanation:

Options for this question are:

  • <em>They both lack a nucleus and contain  cytoplasm. </em>
  • <em>The unique functional adaptations of Archaea are more similar to Eukarya adaptations.  </em>
  • <em> They both evolved in the same geological time period. </em>
  • <em> </em><em>Genetically, the Archaea are more similar to Eukarya than Bacteria. </em>
  • <em> They both have membrane-bound organelles. </em>
  • <em> Archaea is not closer to Eukarya because it contains prokaryotic cells just like Bacteria.</em>

Archaea are unicellular prokaryotic organisms, which share many characteristics with bacteria, however, the existence of metabolic functions and genes similar to eukaryotic organisms suggest that there is a genetic link between the two. Even the enzymes responsible for genetic processing, such as transcriptases and translation enzymes, are similar to those in eukaryotic cells.

The theory that establishes the relationship between Archaea and Eukaryotic suggests the existence of a common ancestor, whose later evolution allowed an Archaea to join a protobacteria to form a eukaryotic cell, and hence their genetic relationship.
