In a certain plant species, the allele for yellow seeds (y) is dominant to the allele for green seeds. what is the phenotype result of a cross between a true-breeding yellow-seeded group of plants and a true-breeding green-seeded group of plants? a. all yellow seeds; no green seeds b. all green seeds; no yellow seeds c. 1/4 green seeds; 3/4 yellow seeds d. 1/4 yellow seeds; 3/4 green seeds @pinkfloyd

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
