Answer:
Option (C).
Explanation:
Membrane potential may be defined as the difference in the electric potential of the inside and outside of the cell. The resting membrane potential of neuronal cell is -70mV.
Pufferfish contains tetrodotoxin that blocks the voltage gated sodium channels. The movement of sodium ions inside the cell causes the depolarization of cell and makes the cell membrane potential towards more positive. This tetrodotoxin causes the normal resting potential but the cell are not able to depolarize if the stimulus is given to the cell.
Thus, the correct answer is option (c).
<span>Most vulnerable side is the ventral because in the dorsal side there is the backbone. Most of the harder bones are on the dorsal side. So then the ventral side also known as the belly side is more vulnerable and softer.Sorry I took Forever LOL</span>
Answer:
A. 1
Explanation:
pH is a measure of how acidic/basic a substance is. The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.
note: the closer you are to the neutral the weaker it gets.
Answer: Raptorial birds especially the forest eagles, hawk-eagles, Accipiter hawks, and falcons are the most likely species to prey on adult parrots and macaws.
Explanation:
Answer:
Changing temperature causes extinction or removal of organism from that place.
Explanation:
Small changes to both biotic and abiotic components can have major effects on an ecosystem because these are the factors on which the ecosystem depends. For example, if the temperature of the ecosystem increases from its limit, it makes the environment unfavourable for the organism so due to this change, the organism migrated to other location otherwise they will die due to unfavourable environment.
