Answer:
Allan Savory noticed that grasslands co-evolved with large numbers of migrating ruminants, and therefore are co-dependent on each other's survival. These animals grouped together and constantly bunched due to the predator-prey connection, eat the grasses following the seasons throughout their migration in arid regions (Brittleness scale, of Non-Brittle to Brittle environments).
As they move, they drop nutrient-rich dung and urine, while trampling organic litter (live or dead grasses, leaves, etc) and seeds into the soil. These actions break down materials into the surface, providing more covered soil and keeping materials from chemically decomposing (oxidation, as opposed to the fast biological decomposition that occurs in areas with consistent rainfall(Non-Brittle)). The true testament to his insights of Holistic Management re: grasslands is known as the 4th Key Insight: That time, rather than numbers governs over-grazing or over-trampling.
The important component here is that the time exposed to these animals plays the significant role in whether you have healthy grasslands, not the number of animals exposed to the area of consideration. The amount of "rest" (time) for grasses between eating or trampling is just as crucial as the time in an exposure.

<span>In order for a cell to become cancerous, oncogenes must be active and tumor suppressors inactive.
Oncogenes are genes which carry genetic material capable of inducing cancer. Tumor suppressors, on the other hand, function as a sort of "anti oncogene." In other words, tumor suppressors work to stop uncontrolled cellular growth and prevent cells from becoming cancerous. So if oncogenes are active and tumor suppressors are inactive, then there is nothing to prevent the cell from growing cancerous.</span>

Answer:
A. Species that remained after the extinction were able to radiate, new adaptations arose, and these adaptations produced the diversity seen today.
Explanation:
When species went extinct they also left niches that could be occupied by "new" species; new places to live, places to be filled in the food web and different relationships to be formed. The wide availability of resources made organisms to radiate leading to a "new" diversity of shapes, sizes, and lifestyles.
B. Species that have gone extinct were able to re-evolve from the ancestors that survived the extinction. If you are extinct you are gone forever.
C. Species that remained after the extinction were unable to speciate. Therefore, the number of species on Earth today is lower than the number of species present just before either extinction. The fossil record proves that species have changed over time and the diversity has changed over the history of Earth.
D. Species that remained after the extinction represented all of the lineages that were present before the extinction event. Therefore, extinction did not change the diversity of lineages. Again, the fossil record is evidence that lineages have changed over the history of the Earth.
