accumulations of genetic mutations over time.
Genetic and epigenetic changes compound over time to cause cancer. While aging and chronic inflammation are the major causes of epigenetic changes, carcinogenic substances, UV radiation, and other conditions can also cause genetic changes. Our prior exposure levels and life history are reflected in the accumulation and patterns of changes in normal cells. The majority of accumulated changes are regarded as passengers, although they are linked to cancer drivers as they accumulate. Although only hypothesized for genetic changes, this has been demonstrated for aberrant DNA methylation. However, modern technology has made it possible to assess uncommon point mutations, and research has revealed that the rates of their accumulation do actually correspond with cancer risk.

Answer:
The correct answer to the question, 'which of the following scenarios is representative of how agricultural practice can affect the environment' is A. Option A is chosen because it is the only option that refer to another environment which is different from that of the farm. When fertilizers are washed to nearby ponds as a result of erosion, it causes a lot of negative changes in the pond. For instance, the chemicals in the fertilizer can be poisonous to some of the smaller organisms in the pond, this will result in the death of these organisms. Fertilizer run off can also cause excessive growth of plants such as algae in the pond. This may block out the light necessary for the survival of the organisms in the ponds and may also reduce the amount of oxygen available to the organisms living in the pond.

The change in weather pattern caused forest to become sparse and hot weather caused the reduction of apes as they had less food and difficulty in surviving the climate.
Explanation:
In Miocene epoch volcanic mountain chains were created in Central Africa which abruptly changed the local weather.
The sea-level got drop due to global cooling of that time.
This resulted in continental drift making land connection of Africa with Eurasia.
The primates started migrating through this route.
The African forest become dry causing selective pressures in primates.
The cooler climate in Eurasia caused extinction and migration of primates to Africa in late Miocene epoch.
The hot and humid climate and less woodland caused a reduction in number of apes which were replaced by modern world monkeys.
