Ecologist has proposed following explanation to lead biodiversity at tropic.
a) Higher productivity in the tropics allows for more species
b) Environments are more stable and predictable in the tropics, with fairly constant temperatures and rainfall levels year-round
c) Predators and pathogens limit competition in the tropics, which allows more species to coexist
d) High evolutionary speed at tropic than temperate

NH4+ is toxic to plants, inhibit dinitrogenase and also interfere energy metabolism by dissociating ATP formation from ETC in both mitochondria and chloroplasts. What will plant cells do to avoid this problem?
a) Plant cells avoid ammonium toxicity by rapidly converting the ammonium generated from nitrate assimilation or photorespiration into nitrate
b) Plant cells avoid ammonium toxicity by rapidly converting the ammonium generated from nitrate assimilation or photorespiration into amino acids
c) The pathway for this conversion involves the sequential actions of glutamine synthetase (GS) and glutamate synthase (GOGAT)
d) The pathway for this conversion involves the sequential actions of Aspartate aminotransferase (Asp-AT) and Asparagine synthetase (AS)
