Natural variation provided the phenotypes that natural selection then acted on, over time causing evolution
The answer to this question would be: frequency
The higher intensity of the stimulus, the higher frequency of the action potential will be sent. The nerve can't send a higher action potential, so it firing at higher at higher intensity instead. So when you felt an intense pain, that means the pain receptor is firing more stimulus per second compared to low or mild pain.
The answer should be A plant cell
There are 12 chromosomes contain at the end of meiosis II. The events of meiosis II are most similar to
mitosis, Meiosis replaces gametes for sexual reproduction. Meiosis sexual t is
a Type of reproduction. Meiosis is a Replication
of DNA.
