Answer:
Nitrogen fixation (N2 to NH3/ NH4+ or NO3-)
Nitrification (NH3 to NO3-)
Assimilation (Incorporation of NH3 and NO3- into biological tissues)
Ammonification (organic nitrogen compounds to NH3)
Denitrification(NO3- to N2)
Explanation:
Sperm and egg cells do not go through mitosis, they go through meiosis. Why? Well, in mitosis, cells copy themselves. But in sperm and egg cells, they have to duplicate differently. So, there is no such thing as two different sperm or egg cells that are the same.
<span>The
answer is bone. A new technique of
observing Harris lines (between the diaphysis and epiphysis of long bones), by
use of radiography, of bone is being used to postulate ancient diet of populations.
This is especially used to determine
stressful periods that were characterized
by poor diet (deficiencies) by comparing carbon
and nitrogen isotope ratios</span>
Tropic movements are growth movements in plants in response to certain stimuli such as light and water which result in a permanent direction of the plant towards or away from the very stimuli, whereas nastic movements are temporal and reversible movements of plant organs in reaction towards or away from a certain stimulus such as touch or heat.
