Answer:
A microscopic organism, especially a bacterium, virus or fungus
Explanation:
High-altitude environments present a number of physiological challenges for endothermic animals, as they are characterized by a lower partial pressure of oxygen (<span>) and lower ambient temperatures compared to low-altitude environments at similar latitudes. The reduced </span><span> at high altitude results in reduced oxygen loading in the lungs such that the blood may not carry a sufficient supply of oxygen to the cells of respiring tissues (</span>Bencowitz et al. 1982<span>; </span>Bouverot 1985<span>; </span>Turek et al. 1973<span>). This reduced level of tissue oxygenation can impose severe constraints on aerobic metabolism and may therefore influence an animal's food requirements, water requirements, the capacity for sustained locomotor activity, and the capacity for internal heat production.

The answer is a)<span>
These regions are rich in plankton during summer

Answer:
1/ Climate change
2/ Asteroid impacts
3/ Massive volcanic eruptions
4/ Sun explodes
etc. (all the things above are most likely to happen but alien invasion or things like that is also a theory that you can add depends mostly if you like it or not)
Well banana spider can be referred to 3 different kinds of spiders
1, the golden silk orbweaver (not poisonous?)
2, the argiope appensa (not <span>poisonous)
</span>3, the brazilian wandering spider (is <span>poisonous)</span>
