Wind pollination required a great deal of excess pollen, just so some of it lands, by chance, in the right place. Animal pollination is more selective because animals pick pollen up and carry it directly to where it needs to be. Although there is still a chance that the pollen will be from the wrong plant species, plants can manipulate variations in animal behavior through the structures of their flowers, the time and season of flowering, or the rewards or attractive chemicals they produce to narrow the field of pollinators, and increase the chances of having exactly the right pollen put in exactly the right place.

In neuroscience, depolarization is an "all or nothing" response; what does that
Tom [10]

Answer:

The correct answer is - The neuron's intracellular charge must get more positive to meet a certain  thresh hold in order to depolarize. If the neuron does not hit that threshold, then the  neuron will not fire

Explanation:

In neuroscience, the depolarization of neurons shows the all or none law which is also called as all or nothing response. It states that all action potentials have the same size and the potential or strength of a nerve cell does not depend on the stimulus strength as all are the same size.

If a stimulus reaches a particular threshold cell or fiber will fire so either it will fire or not cross the threshold this is all or nothing response or law and depolarization is an example of it.
