The nervous system interacts with the system to coordinate the internal integration of all the other body systems together.

The endocrine system.

Explanation:

The nervous and endocrine system work together to maintain homeostasis in the body. The endocrine system used chemical signaling I.e hormone produced by it glands and the nervous system uses electrical signals. The nervous system send signals and activates the endocrine system to secrete hormones in order to respond to the signal AME maintain body function.

The endocrine and nervous system work together by influence human behavior, growth, metabolism and reproduction. The nervous system controls all body activities, the endocrine system secretes hormones that regulate these activities.

sexual reproduction produces offspring with novel combinations of genes. species that reproduce sexually must maintain two different types of individuals, males and females, which can limit the ability to colonize new habitats as both sexes must be present.

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
