Capelin are fish found in the atlantic and the arctic oceans. in spring and summer, capelin are usually seen in the region between iceland and greenland. what is the most likely reason for the presence of capelin in these regions? a) these regions are rich in plankton during summer. b) capelin need to migrate from deep to shallow water. c) fishing boats do not visit these regions in the summer. d) capelin need to move into fresh water during this period.

The correct answer is: A) These regions are rich in plankton during summer

Capelin populations do extensive seasonal migrations. During the spring and summer, Capelin fishes migrate for feeding in the plankton-rich oceanic area. Return migration occurs in September to November. Migration of those fishes is linked with ocean currents and water masses.

structure is maintained and sustained by:

-cytoskeleton: gives cells coherence

-cell wall: support

-cytoplasm: shape

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
