Answer:
Bacteria that metabolize NO2- to give rise to NH4+ belongs to the family of denitrifying bacteria and nitrate ammonification bacteria such as pseudomonas.
Explanation:
Denitrifying bacteria uses NO2- as electron aceeptor thus converting the nitrite ion (NO2-) to ammonium ion(NH4+).
a) The above reaction is a reduction reaction because NO2- or nitrite ion accept electron to generated its reduced form known as ammonium(NH4+).
b) NO2- acting as electron acceptor in this reaction.
The answer to this question would be: False
The rate of diffusion should not be influenced by molecular weight. Big molecule might not be able to pass the membrane though.
Diffusion happens when there is a difference/gradient in the concentration of the molecules. If the difference is higher, then the diffusion rate will be increased.
Answer:
it's too early for this, also im pretty sure all we know is that their ancestors are wolves and that's it.
Explanation:
The ones about enzymes are chemical digestion and the ones about chewing are mechanical digestion.
