Answer:1).A nonrenewable resource is a natural substance that is not replenished with the speed at which it is consumed. It is a finite resource.
2)Rocks are made of minerals, like quartz, calcite, feldspars, and micas. Most rocks are made from more than one mineral, but there are quite a few kinds that are made from only one mineral. Minerals are not rocks, rocks are made of minerals.
3)Coal is a very useful rock that formed over millions of years from the ... No, coal is not a mineral because coal is made of dead plants.
4)The relatively cheap cost of fossil fuels is a major positive aspect. They are in abundant supply, which makes them inexpensive to drill or mine for. In particular, coal is one of the most widely available fossil fuels.
5)High initial costs for material and installation and long ROI (however, with the reduction in the cost of solar over the last 10 years, solar is becoming more cost feasible every day) Needs lots of space as efficiency is not 100% yet. No solar power at night so there is a need for a large battery bank.
6)Asphalt, also known as bitumen is a sticky, black, highly viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or it may not.
7)When fossil fuels are burned, they release toxic gases into the air that cause pollution and increase global warming.
8)The soil considered an important resources because : It provides food through agriculture. It is the source of nutrients for many forms of life. Many valuable minerals are explored from the soil.
9)Renewable resources are an energy source that cannot be depleted and are able to supply a continuous source of clean energy.
10)the cost of processing the bottle after it was no longer used
11)The rock display with smaller holes shows copper drilling, which is deep underground.
Explanation:
Those resources which can not be made again is called nonrenewable resource.
According to the question,
A resource that is in limited supply is nonrenewable resources.A resource that is used for energy is a renewable resource. For example - sunlight.A resource that harms the environment when it is used, might be both renewable and nonrenewable resources.A resource that can replace itself quickly is renewable resources.

With support for cases such as Brown v. Board of Education, the National Association for the Advancement of Colored People (NA
its attention during the early days of the civil rights movement on doing which of the following?
Answer:
Although the Declaration of Independence stated that "All men are created equal," due to the institution of slavery, this statement was not to be grounded in law in the United States until after the Civil War (and, arguably, not completely fulfilled for many years thereafter). In 1865, the Thirteenth Amendment was ratified and finally put an end to slavery. Moreover, the Fourteenth Amendment (1868) strengthened the legal rights of newly freed slaves by stating, among other things, that no state shall deprive anyone of either "due process of law" or of the "equal protection of the law." Finally, the Fifteenth Amendment (1870) further strengthened the legal rights of newly freed slaves by prohibiting states from denying anyone the right to vote due to race.
Despite these Amendments, African Americans were often treated differently than whites in many parts of the country, especially in the South. In fact, many state legislatures enacted laws that led to the legally mandated segregation of the races. In other words, the laws of many states decreed that blacks and whites could not use the same public facilities, ride the same buses, attend the same schools, etc. These laws came to be known as Jim Crow laws. Although many people felt that these laws were unjust, it was not until the 1890s that they were directly challenged in court. In 1892, an African-American man named Homer Plessy refused to give up his seat to a white man on a train in New Orleans, as he was required to do by Louisiana state law. For this action he was arrested. Plessy, contending that the Louisiana law separating blacks from whites on trains violated the "equal protection clause" of the Fourteenth Amendment to the U.S. Constitution, decided to fight his arrest in court. By 1896, his case had made it all the way to the United States Supreme Court. By a vote of 8-1, the Supreme Court ruled against Plessy. In the case of Plessy v. Ferguson, Justice Henry Billings Brown, writing the majority opinion, stated that:

Is GMO is good or bad? And why? Can you please explain to me your answer so that i can understand, thanks!
Answer:
There is no data to indicate that consumption of GMOs is bad for human health. ... In addition, over the two decades that GMOs have been on the market, there have been no occurrences of health issues due to genetically modified organism
Explanation:
but its your own opinion
Answer: GMOs are generally though of as bad
Explanation: GMO stands for Genetically Modified Organism.
People take genes from one plant, lets say from a plant that can withstand cold temperatures, and puts it into another plant. This can give the gene of withstanding cold temperatures to the new plant.
A long time ago people would breed plants until they got traits that they like. This takes a very long time. Now with GMOs, you can get the traits you want much faster.
People are concerned with GMOs for allergies, cancer, and environmental harm. Current research hasn't outlined too many risks of GMOs yet as long-term research is still needed.

Extra water makes plants shiny, increasing the likelihood that consumers
will purchase the plants.
Extra water creates a hypotonic solution around plant cells, which causes
water to diffuse into the cell creating turgor pressure.
Extra water creates a hypertonic solution around plant cells, which causes
water to diffuse out of the cell plasmolysing the cells.

This is the equation for the thermite reaction:
Fe2O3 + 2Al = Al2O3 + 2Fe
You know the charge on the Al and O ions because you know how many electrons each atoms "wants" to give or take by looking at their position on the periodic table (and because it was listed on the cards). Fe is element 26, iron, in the middle of the periodic table. Since it forms Fe2

O3
3
, what charge does the Fe ion have?
The charge of Fe in Fe₂O₃ is +3.
Let's consider the equation for the thermite reaction:
Fe₂O₃ + 2 Al ⇒ Al₂O₃ + 2 Fe
One of the reactants is ferric oxide, we can calculate the charge of Fe in Fe₂O₃ considering that:
The sum of the charges of the atoms is equal to the charge of the compound.The charge of a neutral compound is 0.The charge of O in oxides is -2.The charge of Fe in Fe₂O₃ is:

The charge of Fe in Fe₂O₃ is +3.
