A common feature of starch and glycogen is that molecules of both A. are important structural components of plant cell walls B. contain repeated monomers of glucose and galactose C. form microfibrils that give support to connective tissue fibers D. store energy for use by living organisms

D. store energy for use by living organisms

Explanation:

Starch and glycogen are polymers made up of several units of glucose. Starch and glycogen functions to store energy that is used by living organisms.

Starch is a stored form of energy found in plants whereas glycogen is a stored form of energy in animals.

Hence, the correct option is "D".

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

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.
