{I got this from online hope it helps}The earliest known mammals were the morganucodontids, tiny shrew-size creatures that lived in the shadows of the dinosaurs 210 million years ago. They were one of several different mammal lineages that emerged around that time. All living mammals today, including us, descend from the one line that survived. So yeah it’s true
The community should invest in the production of biomass energy as an alternative source of energy, given the large surplus of waste corn.
Explanation:
When a community has a considerable amount of organic waste, the combustion of such wastes can be used for energy production, which is considered to be obtaining energy by biomass.
For a community with this characteristics, biomass becomes the best option for alternative energy, whereas waste is being used -which is an adequate disposal of solid waste- in addition to the fact that the production of pollutants is lower, compared to the use of fossil fuels.
Other sources of alternative energy are not possible because:
The climatic conditions -frequent rains- do not allow to take advantage of solar energy.
The low wind speed is not useful for wind power.
The low flow of the rivers makes the installation of hydroelectric plants impossible.
For this community it is a fact that the best alternative energy option is to use waste corn as fuel.
Answer: An observation is something you sense: taste, touch, smell, see, or hear. An inference is something you decide or think about a thing or event after you observe it.
Examples: I observe that this shoe smells musty. (Observation) I infer that my teacher has a kid.
