Biology
1 answer:
Evgen [1.6K]3 years ago
3 0

An action potential is caused by either threshold or suprathreshold stimuli upon a neuron. It consists of four phases; hypopolarization, depolarization, overshoot, and repolarization. An action potential propagates along the cell membrane of an axon until it reaches the terminal button.

Because global temperatures are ________[1], some species are seeking out ______[2] elevations in the Himalayas to colonize. Sci
Vsevolod [243]

Answer:

increasing[1], higher[2], space[3], food[4], climate change[5].

Explanation:

Because global temperatures are <u>increasing[1]</u>, some species are seeking out <u>higher[2]</u> elevations in the Himalayas to colonize.  Scientists were worried that these organisms would not have enough <u>space[3]</u> to live, but they have found that there is adequate <u>food[4]</u> at higher elevations. This movement may help these organisms survive the effects of <u>climate change[5].</u>

(Although am positive about 1, 2 and 5, you will need to double check 3 and 4.  What I can tell you is that I don't think lifespan has to do with 3 or 4.  I chose space and food simply due to the thought that more species moving to higher elevations allows for less space to live, but more prey to be hunted easier.)
