Answer:
The fossil record shows that early species of horses were generally small in size, but many lineages since about 30 million years ago exhibit substantial change toward an increase in size.
Explanation:
It was demonstrated that variation in size as well as in diet during the last millions of years, were consequences of different climatic and geographic changes.
The fragmentation of horses´ populations was associated with habitat heterogeneity and to a new tendency for colonizing new areas that were not accessible before that time.
When great plains with grasslands appeared, horses moved to these new areas, reproduced, and got bigger and taller with time. The new species became even bigger. They evolved from small mammals that fed on shrubs in the forests, to the big current horses that graze on the open plains.
Answer:
A compound that is being oxidized loses at least one electron, while a compound that is reduced gains at least 1 electron. To remember the difference, a mnemonic device such as OIL (oxidation is lost), RIG (reduction is gained) is helpful. Oxidation-reduction reactions are illustrated in the figure below.

I do think Ancient Antarctica was situated in a different location from it's locations today because of continental drift, this is caused by the moving of the tectonic plates by the mantle which is under the Earth's crust due to the cooling and heating of magma (or lava, cant remember). this causes the plates to collide with each other, go in opposite ways or "swallow" one another (basically one plate goes under the other causing the one under to melt and reappear where two other plates are separating)
