why do cold-blooded animals, such as snakes and turtles, need to bask in sunshine before they can move as quickly as warm-bloode
saveliy_v [14]

The cold-blooded animals need to bask in sunshine before they can move as quickly as warm-blooded animals on a cold day because it increases their rate of metabolism.

<h3>What are cold-blooded animals?</h3>

Cold-blooded animals are those animals that are not able to regulate and maintain their internal body temperature when there is change in the external environment.

Example of cold-blooded animals are snakes and turtles. They expose themselves to sunlight to help them with their body metabolism.

Therefore, the cold-blooded animals need to bask in sunshine before they can move as quickly as warm-blooded animals on a cold day because it increases their rate of metabolism.

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.)
