Maybe D could be the answer
Answer:
algae growing on the glass
Answer;
-Over 4000
Mathematically, the biomass in the ocean contributes over 4000 times more grams of NPP per year per gram than an equivalent gram of plant biomass in a terrestrial ecosystem.
Explanation;
-Living biomass forms a tiny fraction of Total Ocean carbon but has a very significant influence on the ocean carbon cycle. Every gram of biomass of the primary producers in the ocean contributes more to NPP per year than plant biomass of terrestrial ecosystems.
-In marine ecosystems, phytoplankton is the main source of primary production. The nutrient availability cycles make it important to distinguish between new and regenerated primary production ; the former identifies the annually renewed nitrogen, while the second measures the rapid cycling of nitrogen through ammonia availability.
In this scenario, once in a target tissue, the water soluble hormones which is the answer would then bind to the intracellular receptors inside the cell membrane. Hope this is the right answer and would be of big help then.
