Answer:
The correct answer would be C) 75% large-toothed and 25% small-toothed.
It can be explained with the help of the law of dominance which states that the dominant allele expresses itself completely over the recessive allele in the heterozygous condition.
So, the genotype TT, as well as Tt, will result in the production of dominant trait or character in the offspring.
Thus, three (1 TT and 2 Tt) out of four offspring would have large teeth and only one offspring (tt) would have small teeth.
Hence, we can conclude that 75% of the offspring will have large teeth and only 25% will have small teeth.
Multicellular organisms begin as a single cell. These cells then grow and undergo differentiation, the process by which cells develop specialized forms and functions.In multicellular organisms, cells are often organized into tissues, organs, and organ systems.

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.
