Aerobic respiration<span>, a process that uses oxygen, and </span>anaerobic respiration, a process thatdoesn't<span> use oxygen, are two forms of cellular respiration. Although some cells may engage in just one type of respiration, most cells use both types, depending on an organism's needs. Cellular respiration also occurs outside of macro-organisms, as chemical processes — for example, in fermentation. In general, respiration is used to eliminate waste products and generate energy.</span>

The phase transition in which molecules directly move from a state involving vibration of particles in a fixed position to a state involving random movement of high -speed particles is called : Sublimation
Particles in a fixed position = solid particle
Random movement high speed particles = gas particles
The transition from solid to gas is called sublimation

There appears to still be a lot of debate within science over whether humans or climate change were primarily responsible for the extinction of many of the large mammals during this period. One hypothesis supporting the link to early human hunters is that large animals in sub-Saharan Africa co-evolved with humans as they learned how to use tools and developed ever more effective weapons. When early humans moved into Europe and Asia, taking with them their weapons and hunting skills, the populations of large animals in those areas were not accustomed to human hunting, and were therefore easy prey.
