According to the fossil record, Australia has been home to unique wildlife like kangaroos, koalas, and the duck-billed platypus for thousands of years. Which answer choice below BEST describes the development of these animals that are not found anywhere else on Earth? A.
The unique plants and animals all inhabited in the southeastern region of Pangea. Eventually, Australia separated from the rest of Pangea, taking all of the unique wildlife with it.

B.
Australia separated from Pangea faster than other continents, isolating the plants and animals for a longer period of time. Wildlife on the Australian continent faced unique struggles to survive to which they slowly adapted to overcome over time.

C.
All of the "normal" wildlife in Australia went extinct.

D.
Over the past several generations, humans in Australia have carefully selected individuals of a specific species to create these new and unique modern-day species in order to help them with farming labor.

Oxidation-reduction reactions (often called "redox" for short) are reactions that involve the transfer of electrons from one species to another. oxidation states, or oxidation numbers, allow chemists to keep track of these electron transfers. in general, one element will lose electrons (oxidation), with the result that it will increase in oxidation number, and another element will gain electrons (reduction), thereby decreasing in oxidation number. the species that is oxidized is called the reducing agent or reductant. the species that is reduced is called the oxidizing agent or oxidant. to sum up: oxidation = increase in oxidation state = loss of electrons = reducing agent reduction = decrease in oxidation state = gain of electrons = oxidizing agent part a which element is oxidized in this reaction? fe2o3+3co→2fe+3co2 enter the elemental symbol. view available hint(s) is oxidized part b which element is reduced in this reaction? 2hcl+2kmno4+3h2c2o4→6co2+2mno2+2kcl+4h2o enter the elemental symbol. view available hint(s) is reduced
