Answer;

Statocysts

Explanation;

-The small organs of equilibrium in scyphozoan jellyfishes are called statocysts, and these are borne in more complex sense organs called rhopalium.

The statocyst is a balance sensory receptor present in some aquatic invertebrates, including molluscs, bivalves, cnidarians,ctenophorans, echinoderms, cephalopods and crustaceans. These structures aid in orientation and balance during swimming in medusae and are located around the margin of the bell in Craspedacusta.

The small organs of equilibrium in scyphozoan jellyfishes are called statocysts.

The statocyst is a sensory organ that consists of a sac-like structure which contains a mineralised mass (statolith) and numerous innervated sensory hairs-setae. When the animal accelerates, the statolith's inertia causes it to push against the setae and that’s the way to detect gravity.

humans, along with other animals and plants, have linear chromosomes that are arranged in pairs within the nucleus of the cell. the only human cells that do not contain pairs of chromosomes are reproductive cells, or gametes, which carry just one copy of each chromosome.

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
