Fixation
Nitrogen is converted from atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation. The majority of nitrogen is fixed by bacteria, most of which are symbiotic with plants. Recently fixed ammonia is then converted to biologically useful forms by specialized bacteria
Answer:
The answer to this definition is: ACTION POTENTIAL
Explanation:
Action potential is a phenomenon in nervous system used to describe a change in electrical current that occurs when an impulse passes through a neuron or nerve cell. Action potential is induced when sodium (Na+) ions move from the extracellular environment into the intracellular environment.
Impulse travels across the axon of a neuron and thereby causes a difference in the electric potential i.e. - mv to + mv. This process, according to this question, whereby a change in electrical potential occurs due to the passage of an impulse through a nerve cell is termed ACTION POTENTIAL.
<u>Explanation:</u>
One physical difference between the hands and feet is that the human hands appear to be more flexible than our feet. Also, in terms of size, our feet are smaller than our hands.
Let's assume that our feet become as flexible as our hands and the hands less flexible, it would affect the function they perform.
- If for example, we were to walk with our hands we will fail to achieve stability.
- And if for example, we decide to grab hold of items with our feet we will be unable to do so.
It is also reasonable to expect other primates to have hands and feet that differed from ours because they are necessary so they can adapt to their environment just like humans too.
