Which organisms are eukaryotes? sunflower bacteria cow

sunflower and cow are eukaryotes

Explanation:

A eukaryotic organism is one who have enclosed nucleus ( i.e nucleus is enclosed with in a membrane). However in a prokaryotes the nucleus is exposed. Bacteria’s have exposed nucleus and thus they are prokaryotic organism. Eukaryotic domain includes animals, plants, algae and fungi as its constituent’s members.  

Since sunflower is a plant and cow is an animal, these two lie in the eukaryotic domain of organisms.  

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

one part of the electromagnetic spectrum that arrives on earth as solar radiation from the sun is the visible spectrum. wavelengths of the visible spectrum combine to form what we refer to as

answer - d) ultraviolet radiation.

violet /   380–450 nm / 668–789 thz

violet is number 1 in the chart of visible light.
