Answer:
a. The initial concentration of the substrate
Explanation:
If the researcher keeps the initial concentration of the substrate constant, it will give room to compare the reaction rates under different environmental conditions. The reaction rates will assist the researcher by providing the researcher with the necessary and important information about the enzyme's function in different environments.
Answer:
Nitrogen can be transformed into a utilizable form like NO2 by the fixation process.
Explanation:
The conversion of nitrogen into various chemical forms is described through the Nitrogen cycle. The nitrogen of atmosphere is less usable. However, it can be made usable by various interactions of complex genes that allow nitrogen conversion by different organisms.
One such interactive process is of Fixation. In this method, nitrogen is modified into ammonia by symbiotic microorganism. They have the enzyme called nitrogenase which makes the bond of hydrogen with nitrogen to make ammonia.
I think that a toxin that was introduced into a food web can kill some species but not others because some may have resistances to the toxin, while others, it may be lethal. Also that it did not affect everyone because as Bioaccumulation has stated if affected one organism but their might not be much biomagnification as in much increase in the correlation between the food chains in that area. i think the cat were like the top animal so the key stone animal of the food chain and also it had no predators.
Electrons are found in orbits around the nucleus
