Answer:
whole numbers
Explanation:
Meristic traits are referred to as traits that are countable, hence the phenotypes are described by whole numbers instead of irrational, prime, complex or imaginary numbers. Meristics traits are usually associated with fishes, it is used to characterize different known species of fish or can also be employed in identifying unknown fish species. Meristic studies are mostly done on dead fishes than on living fishes
An example of a countable trait in fishes is the number of gill rakers. The identification of the number of gill rakers can be used in identifying the specie of fish.
Answer:
In this lab, you dissected a flower. The modified leaves that surround the reproductive parts are called petals. These structures help attract pollinators to the flower. The pistil is the female reproductive organ, which contains three segments: the stigma, style, and ovary.
Answer:
The duration that it takes for all voltage-gated Na+ channels to return to a closed, but active (not inactivated) state after the initial rapid depolarization "spike". ( D )
Explanation:
The property of a neuron's action potential that determines the maximum firing rate is ; The duration that it takes for all voltage-gated Na+ channels to return to a closed, but active (not inactivated) state after the initial rapid depolarization "spike".
The firing rate of a neuron defines the number of spikes that a neuron can produce per second and for a typical neuron that number is from 1 spike to 200 spikes per second
