Answer:
D) An original parent DNA strand and one newly synthesized DNA strand comprising a new DNA molecule.
Explanation:
- Semi-conservative replication refers to two strands of DNA unzip, and a new strand is assembled onto each 'conserved' strand.
- The replicated double helix consists of one old strand and one newly synthesised strand.
- It describes the structure of DNA, a twisted helix of two strands with bases joining the strands.
The answer is Domain. It is also referred to as Superkingdoms. There are three domains in current classification system namely; Archaea, Bacteria, and Eukarya. The first two classify single-celled organisms whose cells have no nucleus while Eukarya classifies organism that have a nucleus bound by a membrane. The difference between Archaea and Bacteria is their membrane structure; Archaea’s membrane is characterized by membrane lipids that are branched hydrocarbon chains attached to glycerol by ether linkages, while Bacteria’s is made of unbranched fatty acid chains attached to glycerol by ester linkages.
The higher platform because it is in a higher place and it takes more energy to pull down.

Answer:
It's important for a scientist to try to hold all variables constant except for the independent variable. If a control variable changes during an experiment, it may invalidate the correlation between the dependent and independent variable. When possible, control variables should be identified, measured, and recorded.
