The introduction of a new fish species into a lake resulting in the extinction of several native fish species from the lake is an example of

The taxonomic hierarchy in descending order of size is

If the recessive disease phenylketonuria (PKU) occurs in a genetically constant population with a frequency of 1 in 10000, the frequency of the carrier genotype is

Amplification of a DNA fragment by PCR yields only one faint band of the expected size on an agarose gel. For such a sample, the best way to increase the yield of the PCR product is to

The cellular organelle which function(s) as a store for Ca2+ ion is
