Next generation science standards science and science education are central to the lives of all americans and that when comprehending current events, choosing and using technology, or making informed decisions about one’s healthcare, understanding science is key

Research is the process by which you look for the solution to a problem or the answer to something that we don't know systematically. In this sense, research is the fruit of the curiosity of the human being, of the need to know and explain nature.

The importance of research is that this has been a key instrument for the progress of humanity.

We need to keep in mind that research is not limited to science, all areas of knowledge are subject to constant research. In this way progress is achieved. Thus we have that in economics, education, law, and even in art, research stimulating the development of the professional heritage.

Knowledge expansion

We investigate to know more. The greatest usefulness of research can be said to be the production of new knowledge about the existing one. Knowledge, then, is dynamic and growing.

Imagine that since 1900 no research had been conducted, how would we live in the 21st century? We would still ride carts, infant mortality would be huge, we would die from tuberculosis and measles, we wouldn't have television, much less the Internet.

Know the truth

Doubt and disagreement are the great promoters of many investigations. The knowledge of the truth, of how nature works, of how to explain our reality is largely a product of researchers dedicated to satisfying their questions.

From the investigations of Lynn Margullis (1938-2011) the endosymbiotic theory could be established as the origin of eukaryotic cells. She showed evidence that prokaryotic organisms established symbiotic relationships and from there arose eukaryotic algae and plants.

Hydrogen is the most abundant element of the sun and other stars. This fact was discovered by Cecilia Payne-Gaposchkin (1900-1979) in her astronomical investigations.

Improve Life Quality

Electricity is essential in our daily routines. Less than 300 years ago it was a phenomenon unknown to the majority of the population. Starting with Benjamin Franklin's famous lightning and comet experience, through the invention of Thomas Edison's focus and the creation of electric generators, it is unthinkable to be able to live in our modern societies without electricity.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

question: which statement best describes the different properties of metals?

answer: they are shiny and bend without breaking.

since metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. so therefore, metals are not dull and they are not non-flexible as listed. instead, they are shiny and flexible.

hope this , have a good day. c;
