What is virtual water? Why does it matter?<br><br> - How can you reduce your virtual water impact?
nika2105 [10]

Answer: What is virtual water?  

Virtual water is the volume of water used to produce consumer products. The total volume of water refers to all of the water used in the production of a product. For example, the total volume of water used in a food product would include the water used in the agricultural process, but also the water used in packaging and shipping. Virtual water is essentially all of the “hidden” water behind a product. Every product we consume contains virtual water.

Why should we care?

The majority of the public is unaware of just how much water we consume in our daily lives. It is easy to over-consume, especially when we don’t know just how much we are actually consuming. Without understanding our consumption, it is unlikely that we will succeed in reducing our virtual water footprint. Communities and countries around the world face water issues of scarcity, sustainability, sanitation and accessibility.

Food is the main source of virtual water consumption. In fact, the average American consumes about 33,000 glasses of virtual water every day. These numbers are only expected to increase with increasing populations. Understanding virtual water is a key consideration for sustainable water management.

Explanation: Water covers 70.9 percent of the planet’s surface.

97 per cent of the that water is salt water.

Around the world, 2.1 billion people still lack access to safe water.

Water use is growing at twice the rate of population growth. Unless this trend is reversed and we come up with a way to share water fairly and sustainably throughout the planet, two-thirds of the global population will face water “stress” by 2025

In the USA, the average water footprint per year per capita is as much as the water needed to fill an Olympic swimming pool, an average of 7,786 litres of water per person per day.

In China, the average water footprint is 2,934 litres of water per person per day.

In the Netherlands, 95 per cent of the water footprint of consumption lies somewhere else in the world (due to the amount of imported goods consumed), whereas in India and Paraguay only 3 per cent of the national water footprint of consumption is external.

It requires around 1500 litres of water to produce 1 kilogram of wheat, and a huge 10 times more to produce the same amount of beef.

The water footprint of a cup of coffee is around 140 litres, a cup of tea only around 34 litres.

Isabel's first car had a manual stick shift. After many years of driving an automatic car, she needs to use her sister's car, wh
ankoles [38]

Answer:

Procedural memory

Explanation:

Isabel has to recall the information about using a manual stick shift. For this reason, she is using long-term, explicit, declarative and episodic memory system.

Human memory system can be broadly classified as: sensory memory, short-term memory and long-term memory.

Long-term memory is used to recall information. If the information are about facts, events and experiences then explicit, declarative and episodic memory helps to recall all information. This will help Isabel to recall all information about driving a car with a manual stick shift and she will be able to drive her sister's car.

jeka57 [31]
The correct answer is A. More oxygen is produced during photosynthesis than the plant needs for cellular respiration, so the plant needs to release the extra oxygen.

Which statements are useful for explaining the ratio of black-coated to brown- coated mice in the F2 generation? Select all that
siniylev [52]

Complete question:

A geneticist crossed pure breeding black mice with pure breeding brown mice. All the 992 mice in F1 generation had black coats. When these mice were crossed, the yielded 961 black coated mice and 317 brown coated mice. How could you account for the ratio of black coated to brown coated mice in the F2 generation? Select all that apply

  1. The F1 male produced two kinds of sperm, half carrying an allele for black coat color, and half carrying an allele for brown coat color.
  2. The brown allele segregates together with the black allele and disappears in the F1 generation.  
  3. The F1 female produced two kinds of eggs, half carrying an allele for black coat color, and half carrying an allele for brown coat color.
  4. An approximately three-to-one ratio of black to brown coated mice in the F2 generation is accounted for by the black allele being dominant over the brown allele.

Answer:      

  1. The F1 male produced two kinds of sperm, half carrying an allele for black coat color, and half carrying an allele for brown coat color. APPLIES
  2. The brown allele segregates together with the black allele and disappears in the F1 generation.  DOES NOT APPLY
  3. The F1 female produced two kinds of eggs, half carrying an allele for black coat color, and half carrying an allele for brown coat color. APPLIES
  4. An approximately three-to-one ratio of black to brown coated mice in the F2 generation is accounted for by the black allele being dominant over the brown allele. APPLIES
