Explanation:
Cases in which hair, bones, and teeth are the only evidence retrieved/available from a crime scene are particularly well suited to mDNA(mitochondrial DNA) is comparison and analysis is true.
Explanation:
The mtDNA is used to analyse a variety of samples such as bones, teeth and hair. It is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form of cells.
The trace DNA is a forensic method used for analysing DNA left at the scene of a crime. All the evidence from the scene are sent to the forensic laboratory for analysis. It processes all pieces of evidence from the scene. Once the reults are ready then there will be lead in the detective case.
The correct answer is option (D) Lipid molecules are nonpolar because they repel water molecules, which are polar.
Lipids are organic compounds made up of fatty acids and glycerol. A glycerol is a organic molecule with three hydroxyl groups and a fatty acid consists of a long hydrocarbon chain attached to a carboxyl group.
Lipids are hydrophobic, nonpolar molecules with no charge on their ends. Waxes are long chain nonpolar lipids. The water repelling property of the waxes prevent the water sticking to it and appear as water beads on its surface. The hydrophobic hydrocarbon tail of the fatty acids are hydrophobic in nature making them repel water. The presence of wax on the surface of the plants and animals protects them from dehydration.
Thus, the nonpolar property of lipids make it insoluble in the polar solvents like water as there is no interaction or sharing of electrons between them.
Answer:
relative location is the position of something relative to another landmark. For example, you might say you're 50 miles west of Houston.
