Answer:
b. The surfaces of the membrane are nonpermeable.
Explanation:
This helps the cell membrane to protect the cell.
Radioimmunoassay (RIA) is a test that combines radioactive chemicals and antibodies to detect minute quantities of substances in a patient's blood.
In 1959, biophysicist Rosalyn Yalow and physician Solomon A. Berson developed a sensitive method for measuring very small amounts of a substance in the blood called radioimmunoassay (RIA).
Radioimmunoassay (RIA) is a technique that make use of radioisotopes, usually iodine-125, as a tag or label for the detection of antigen. This technique determines the concentration of an antigen based on the competitive binding between radiolabeled and unlabeled antigen for its specific high affinity antibody.
It is very sensitive that it can measure concentrations up to 0.001 μg/ml.

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.

Polymerization would be the answer you're looking for.
A, as with all organisms, growth is always the primary result of cell division, the mitosis type, meiosis cell division results in gametes (sperm and eggs)
