Answer:
Sub-threshold
Explanation:
If the stimulus is too small to generate the action potential, it is considered as subthreshold stimulus. Subthreshold stimulus causes the opening of small number of sodium channel i.e. not enough to generate action potential because action potential is generated by complete reversal of membrane polarity. Slight depolarization is caused by subthreshold stimulus by the opening of inadequate number of sodium channel but its magnitude is not enough to reach the threshold voltage. Consequently the action potential is not generated.
The response produced by subthreshold stimulus is called as local response or local depolarization because it could not travel further. The minimum stimulus required to generate the action potential is call as threshold stimulus and stimulus greater than threshold stimulus is called as suprathreshold stimulus. It changes the frequency of generated action potential.

The right answer is Asexual reproduction produces offspring that are identical to the parent.
Sexual reproduction is ensured by fertilization, that is to say by fusion of male and female gametes giving an egg (or zygote). This reproduction allows the maintenance of a genetic diversity within the populations, because it ensures the genetic mixing.
Asexual reproduction (sometimes vegetative propagation) refers to all other means of multiplication in which neither gamete nor fertilization occurs. In this case, the sex of the parents and the descendants remains identical, because only the mitosis ensures the transmission of the genetic information to the new cells. It is a form of natural cloning.
