SOMEONE PLEASE HELP!What is Binominal system of Nomenclature.

This is a formal system of naming species of living things by giving each a name composed of two parts.

Explanation:

It is a system of giving name ( naming) a species of living organisms. As the name suggests, there should be two parts for the name( like homo sapiens- scientific name for humans) and generally the names are derived from latin or greek. It can be derived from other languages too.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
