Answer:
The answer is Option C: Index fossils.
Explanation:
Index fossils are used to identify geologic periods or faunal stages in rock layers. These fossils must have a wide geographic distribution and manifest obvious evolutionary trends to help geologists and others who need this geological data to better understand the time scale and to pinpoint a time period. For example, ammonites were common during the Mesozoic Era, but they were extinct by the Cretaceous period. Geologists would use ammonites to help determine this time frame if present.
Answer:
There is a higher concentration of people who live in the northern hemisphere than the southern hemisphere.
Explanation:
A is not correct because the equatorial region is not densely populated, but it is actually sparsely populated.
B is not correct because the southern hemisphere doesn't have a higher concetration of people than the northern hemisphere.
C is not correct because if that was the case the population density would have been the highest either on the Equator or the poles, and that is not the case at all.
D is not correct because the population density is related to the concept of agricultural production.
E is correct because the northern hemisphere has a higher concentration of population than the southern hemisphere, and this is largely due to the fact that there is much more land on the northern hemisphere, thus a much larger area where there are suitable conditions for living.

Answer:
subsistence agriculture, is a mode of agriculture in which a plot of land produces only enough food to feed the family or small community working it. All produce grown is intended for consumption purposes as opposed to market sale or trade. Historically and currently a difficult way of life, subsistence farming is considered by many a backward lifestyle that should be transformed into industrialized communities and commercial farming throughout the world in order to overcome problems of poverty and famine. The numerous obstacles that have prevented this to date suggest that a complex array of factors, not only technological but also economic, political, educational, and social, are involved. An alternative perspective, primarily from the feminist voice, maintains that the subsistence lifestyle holds the key to sustainability as human relationships and harmony with the environment have priority over material measures of wealth. Although the poverty suffered by many of those who have never developed beyond subsistence levels of production in farming is something that needs to be overcome, it does appear that the ideas inherent in much of subsistence farming—cooperation, local, ecologically appropriate—are positive attributes that must be preserved in our efforts to improve the lives of all people throughout the world.
