The more probable answer is b: power plant effluent; golf course runoff, although a: <span>power plant effluent; an underground coal mine drain, is also a possible answer.
The source of effluent from a power plant occupies a small, well defined space, i.e. an effluent pipe. This is what is known as a point source, as you can identify with high confidence the spatial and temporal boundaries of the source of pollution. Point sources are relatively easy to quantify and manage because they are so well defined in space and time. Reducing pollution from point sources could be achieved by simply treating effluent to a higher standard or reducing the amount of effluent released. Runoff from land, such as a golf course, is what is defined as a non-point source pollutant. The spatial and temporal aspects of this sort of pollution are much harder to define, as the pathways of runoff from the land into the river may be highly dispersed and variable over time. These sorts of pollution are therefore much harder to quantify and manage.</span>

The heterozygous for three characteristics have 9 possible genotypes.
<u>Explanation:</u>
There are three types of genotypes. The homozygous dominant (AA), Homozygous recessive (aa) and heterozygous (Aa). Genotypes are the specific combination of alleles present in the individual. Genotypes are the genetic makeup of the cell and it is the genetic identity of an individual. Heterozygous means combination of particular alleles.
Genotypes are normally expressed in capital and small letters. When heterozygous three characteristics in genotype link with each other according to Mendel’s law produce offspring of nine different characteristics.
Parathyriod glands produce a parathyriod hormone aka PTH
Answer:
Gram-positive bacteria, fungi, endospores, prions
Explanation:
The above mentioned answer is in increasing order which are resistant to chemical biocides.
Gram positive bacterias are the easiest to destroy, then fungi is difficult than bacteria, endospore is more difficult to remove or destroy by chemical biocides and prions are the most resistant protein particles to the chemical biocides.
Prions are very difficult to kill by standard sterilization and disinfection procedures.
