Which describes the cells of a wilted plant? the central vacuoles contain little water, the plasmodesmata are closed, the chloroplasts contain little water, the walls have lost their shape

The answer is A: 'The central vacuoles contain little water'. Wilting occurs due to a plant losing more water than it can absorb through its roots from the ground. Wilting results in a loss of turgor pressure to almost zero.Typically, wilting occurs during very low soil moisture conditions. However, wilting can also occur under extreme cold conditions and in very saline soil.

DNA amplification process is used to form multiple copies of DNA sequences and the process of polymerase chain reaction (PCR) used for DNA amplification or to amplify a specific region of DNA.

So, the small sample quantities will be modified by using the PCR process that will amplify the eDNA so that they can be analyzed. So there are three basic steps in a PCR process that include (1) Double-stranded DNA is denatured into a single strand; (2) Rach single strand is then annealed by primers to form new strand; and (3) At the end, the new DNA strands are extended form the primers.

The amplified DNA at the end can be analyzed easily.
