Answer:
Shield volcanoes are built by many layers over time and the layers are usually of very similar composition. The low viscosity also means that shield eruptions are non-explosive. There are two types of lava flows, pahoehoe which is a ropy type of lava that flows easily (low viscosity).
To answer this item, we let x be the number that is not unknown in this item such that the situation in this problem can be expressed as follows,
x - 9.3 = 68.91
Adding 9.3 to both sides of the equation,
x - 9.3 + 9.3 = 68.91 + 9.3
Simplifying,
x = 78.21
The answer to this item is 78.21, this I think is the first choice except that it is mistakenly written as 7.21 only.
Human evolution and development is the process by which a human is beings developed on Earth from a now-extinct primates. Viewed from zoologically, we as humans are a Homo sapiens, a culture-bearing the upright-walking species that do lives on the ground and very likely have first evolved in Africa about 315,000 years ago. We are also now the only living members that what many zoologists are refer to as the human tribe, Hominini, but that there is abundant fossil as evidence to indicate that we were also preceded for millions of years by other hominins,
such as Ardipithecus, Australopithecus, and also other species of Homo, and that in our species also lived for a much time contemporaneously with at least one of other member of our present genus, H. neanderthalensis (the Neanderthals). In addition, to we and our predecessors have to always shared the Earth with other apelike primates, from the modern-day gorilla have the long-extinct Dryopithecus. That we can and the extinct of hominins are somehow related to and also that we and the apes, both living and also extinct, are also have somehow the related is accepted by the anthropologists and biologists in everywhere.
