Water footprint: (noun) the amount of fresh water utilized in the production or supply of the goods and services used by a particular person or group.
Basically, it's a measure of humanity's appropriation of fresh water in volumes of water consumed and/or polluted.
Yes, the capital of a state or country is that state/country's capital city. Santiago is Chile's capital city. For example, the capital of the United States is Washington D.C., which is a city.
Genetic modification is a special set of gene technology that alters the genetic machinery of such living organisms as animals, plants or microorganisms. Combining genes from different organisms is known as recombinant DNA technology and the resulting organism is said to be ‘Genetically modified (GM)’, ‘Genetically engineered’ or ‘Transgenic’. The principal transgenic crops grown commercially in field are herbicide and insecticide resistant soybeans, corn, cotton and canola. Other crops grown commercially and/or field-tested are sweet potato resistant to a virus that could destroy most of the African harvest, rice with increased iron and vitamins that may alleviate chronic malnutrition in Asian countries and a variety of plants that are able to survive weather extremes. There are bananas that produce human vaccines against infectious diseases such as hepatitis B, fish that mature more quickly, fruit and nut trees that yield years earlier and plants that produce new plastics with unique properties. But here is one thing I learned. GMO Is a very bad issue since basically people are spraying chemicals on the plants which we eat. There are these 2 things I want you to know whne your in a store picking out your food. Organic vegetables? Good! it doesn't say organic or anything? that means it's not organic it's usually 98% GM in my opinion. GMO can affect your body and how it functions. I Hope this helps! it took so long to write!

Answer:
- the first direct detection of gravitational waves came in 2015
- gravitational waves are predicted to travel through space at the speed of light
- the existence of gravitational waves is predicted by Einstein's general theory of relativity
Explanation:
The gravitational waves are waves that are produced by the objects, and depending on the mass of the object they can be stronger or weaker in their influence.
These waves have been in the minds of the scientists for more than a century now, with Einstein predicting them in his theory of relativity. The only problem with these waves was that there was no proof of them. The proof finally came in 2015 when these waves were detected from the first time, with two black holes to be thanked for that as they were the source of them.
These waves are predicted to be able to travel with the speed of light through space when they have small amplitudes.
