Answer:
true
Explanation:
im not quite sure what the answer is but if its true and false then the answer is true
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.
Answer:
<em>Tiktaalik roseae</em>
Explanation:
The discovery of the fossil, <em>Tiktaalik roseae</em> on a Canadian island gives credence to the fact that animals moved from living in water to living on dry land. This fish which has feature of land animals such as a neck, skull, and ribs is believed to have lived some 375 million years ago. It also has features of fish such as the fins and scales.
The discovery of this fossil is important to scientists because it confirmed their believe that there should be an organism that would prove that life transitioned from water to land. The fossil was discovered in the year 2004.
