Answer:
Natural organic matter is ubiquitous in soils, waters and sediments. In agriculture, natural organic matter is important because of its positive effects on the structure, water retention and nutrient properties of soils.
Natural organic matter also interacts with metal ions and minerals to form complexes of widely differing chemical and biological nature. Solubility, mobility and toxicity of many trace metals are strongly correlated with the concentration of natural organic matter in soil and water.
Natural organic matter creates problems for the water supply industry, however, requiring removal to minimize water color and giving rise to potentially harmful chemical byproducts as a result of chlorination. Through a process called "bio-fouling," natural organic matter is also a major culprit in degrading the performance of membrane filtration systems used for water purification and desalination.

Does this answer your question or do you need me to answer it differently because I kind of confused myself lol.
Answer:
Steven has heterozygous genotype.
Explanation:
Tongue rolling is a dominant trait, that means the trait can express itself at the homozygous dominant and as well as in the heterozygous condition. The recessive homozygous condition is not able to express this trait.
Steven can roll his trait, this means his genotype is either homozygous dominant or heterozygous. The wife is recessive for the trait. Their son cannot roll his tongue, this means the Steven is heterozygous dominant. If the Steven is homozygous dominant his son will be able to express the trait.
Thus, the answer is Steven has heterozygous genotype.
Turtles belong to the order <u>Testudines</u><u>.</u>
Snakes and marine iguanas below to the order <u>Squamata Oppel</u>
<h3>What are reptiles?</h3>
Reptiles are the animals in the class Reptilia, a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates and rhynchocephalians.
The marine iguana, also known as the sea iguana, saltwater iguana, or Galápagos marine iguana, is a type of iguana that can only be found in the Galapagos Islands. It is a marine reptile that can forage in the sea for algae, which accounts for nearly all of its diet, making it unique among modern lizards.
Turtles are a type of reptile known as a Testudine, and they have a shell made primarily of their ribs. The Pleurodira and Cryptodira groups of modern turtles are distinguished by the way their heads retract.
