Viruses are not considered living because they cannot survive without a host organism, and they do not exhibit the characteristics of life.
Hydrologists are most likely to perform actions relating to estimating the amount of groundwater in an aquifer.
<h3>Hydrologists</h3>
Hydrologists are scientists that specialize in the study of how water relates to the various crusts of the earth.
Hydrology in itself refers to the branch of science that studies how water moves relative to the earth's crusts.
Thus, species identification, age of fossils, or extracting underground oils have nothing to do with the work of hydrologists.

Answer: - Predict an unknown genotype of a purebred dominant plant.
Explanation:
The genetic make up of the organism is called as the genotype. It describes the form of genes or allelic forms present in the organism. A test cross is used to determine the genotype of the organism. In this cross the organism with the unknown genotype is done with that of the organism with the known genotype. It also determines the fact that the organism is either homozygous dominant or hetrozygous.
On the basis of the above description, Predict an unknown genotype of a purebred dominant plant.
Answer:
The correct answer is d. hydronium ion.
Explanation:
Hydronium ion is a positively charged molecule that has three hydrogen atom bonded with an oxygen atom. Hydronium ion is formed when the water molecule gains an extra H+ ion from somewhere.
This H+ ion easily form bonds with one of the lone pairs present on the water molecules. H2O is also a polar molecule and has a partially positive charge due to which the extra H+ ions get attracted to the negative pole of water and make hydronium ion. Therefore the correct answer is d.
