A large population of wildcats is broken up into several small groups as a result of geogrpahic isolation over a long period of time these groups will most likely become

The correct answer is - reproductively isolated.

Explanation:

Reproductively isolated organisms are the organisms that are occurred due to the split in two or more small groups as a result of geographical isolation over a longer time period from a single large group by process of natural evolution.

In the given case of wildcats which is splits into several small groups due to geographical isolation over a long period of time these groups of wildcats become reproductively isolated.

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
