Fossils fuels produce waste that exposes humans to dangerous levels of radiation.

When fossil fuels are burned, they release toxic gases into the air that cause pollution and increase global warming.


Fossil fuels release carbon dioxide which plants use to make food.


Why is soil considered a vital resource?(1 point)

It is less expensive than fossil fuels.


It produces less pollutants than fossil fuels.

It consists of carbon and hydrogen molecules.

Use the scenario to answer the question.

Your class goes on a field trip to observe drilling machinery. The geologists at the drill site show you displays of drilled rocks to compare different types of drills and methods. The drilled holes in one rock display are significantly larger than the holes drilled in the display next to it. Given this information, which statement is correct? (1 point)

The rock display with larger holes shows petroleum drilling, which is deep underground.


The rock display with smaller holes shows petroleum drilling, which is closer to the surface.


The rock display with smaller holes shows copper drilling, which is deep underground.


The rock display with larger holes shows copper drilling, which is closer to the surface.

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.

Stem cells are used to treat some human diseases.
Stem cells can be collected from early embryos. These stem cells have not begun to
differentiate, so they could be used to produce any kind of cell, tissue or organ. The
use of embryonic stem cells to treat human diseases is new and for some diseases,
trials on patients are happening now.
Stem cells can also be collected from adult bone marrow. The operation is simple
but may be painful. Stem cells in bone marrow mainly differentiate to form blood
cells. These stem cells have been used successfully for many years to treat some
kinds of blood disease. Recently there have been trials of other types of stem cell
from bone marrow. These stem cells are used to treat diseases such as heart
disease
Evaluate the use of stem cells from embryos or from adult bone marrow for treating
human diseases
You should give a conclusion to your evaluation.
