Introduction: Over 80% of our energy comes from the burning of fossil fuels such as oil, gas, and coal. Fossil fuels are fairly cheap and plentiful, but there are several problems:
Fossil fuels are nonrenewable resources. That means there is a limited supply. Once the world runs out, there is no way to get more.
Burning fossil fuels adds carbon dioxide to the air. Most scientists agree that this causes the gradual warming of Earth’s climate, or global warming.
Question: What types of energy do not harm our environment?
Describe: Four examples of renewable resources are featured in the Energy Conversions Gizmo. These resources are produced all the time, so they will not run out. Read about each energy source, and then explain how each is produced in your own words.
A.
Wind power:
B.
Water power (also called hydroelectricity):
C.
Solar power:
D.
Ethanol:
On your own: Learn more about one of these renewable resources using the internet or by reading library books. Explain its advantages and disadvantages to your teacher and class.
Answer:
So your answers would be, A ( wind power) , B(water power), C ( solar power)
A ( wind power) is produce by blades to collect kinetic energy from the wind. The wind puts lift on the blades, causing them to whirl.The blades are connected to a drive shaft that spins an electric generator that generates electricity.
B ( water power) is produced by water power plants, water flowes through a pipe and pushes the blades causing a turbine to spin and to produce eletricity.
c ( solar power) is cause by " nuclear fusion" which takes place in the sun. Protons from hydrogen atoms fuse to generate helium atoms when they collide violently near the sun's core. This process, known as a PP (proton-proton) chain reaction, generates a tremendous amount of energy.
Explanation:
i hope this is what u were looking for :D
( also be careful with the water power, water can run out and we will have no more left so)
Explain how group behavior affects the survival and reproduction of Herring Gulls. Support your answer with evidence from the information above and your knowledge of science
Answer:
The tapping behavior is innate, or genetically preprogrammed. Herring gull chicks will peck at the red dots of their parents' beaks without any prior training. In fact, a baby herring gull can be tricked by a yellow stick adorned with a red dot—it will peck at the stick just as eagerly as it would at a parent's beak.^2
2
squared
This is just one example of an innate behavior, or behavior that's genetically hardwired in an organism. Given the right cues, an organism will perform an innate behavior without the need for prior experience or learning. Innate behaviors tend to be very predictable—like the herring gull tapping—and they are often performed in a very similar way by all members of a species.

Genes and Proteins in Hemophilia
Genetic researchers at Bay Medical Company are working to improve treatments for hemophilia. Currently, they are investigating the possibilities of gene therapy, which involves changing a person’s genes so that that person no longer has hemophilia. In order to help Bay Medical Company with their research, read the passage below and then answer the question.
Genes are instructions for proteins. Your traits are determined by the kinds of proteins your body makes. For example, when you get a cut, clotting factor proteins connect to form scabs. People with hemophilia do not have a version of the gene with the right instructions for making clotting factor VIII protein. Without the right instructions, their cells can’t make the proteins needed to form scabs. Healthy people have at least one copy of the gene that provides the right instructions for making all of the clotting factor proteins.
If genetic researchers found a way to change a person’s genes, would they be able to cure hemophilia? Why or why not?
Why do the principles of relative dating not indicate the absolute age of a rock unit?
Answer:
Remember that in relative dating, scientists do not determine the exact age of a fossil or rock. They look at a sequence of rocks to try to decipher when an event occurred relative to the other events represented in that sequence. The relative age of a rock, then, is its age in comparison with other rocks.
Explanation:
In relative dating, scientists do not determine the exact age of a fossil or rock.
What is Relative dating?They look at a sequence of rocks to try to decipher when an event occurred relative to the other events represented in that sequence. The relative age of a rock, then, is its age in comparison with other rocks.
Absolute dating and relative dating are the two types of dating techniques employed by archaeologists. Using the relationships between objects, we can tell which ones are older or younger.
Archaeologists can use this relationship to determine that artefacts discovered far below the surface are older than those discovered near to the surface.
Therefore, In relative dating, scientists do not determine the exact age of a fossil or rock.

What are the pros and cons of nuclear power?
Answer:
The pros and cons are simple.
Explanation:
First of all, the cost is fairly low. Generating electricity in a nuclear power plant is cost-competitive to fossil fuels and renewable environmentally-friendly resources. This is despite the fact that the initial construction costs are often several billion dollars and there are ongoing enrichment and waste disposal issues that must be managed. Because it is such an affordable energy resource, it allows most people to have access to the power they need for the modern life.
HOWEVER, it contains a negative impact to our precious enviorment. It destroys this whole Earth.

What does an organism typically use proteins for?
Check all that are true.
energy
to speed up cellular processes
structure
to store information for the cell
Answer:
to speed up cellular processes, structure
Explanation:
Typically proteins are not used for energy in organisms. Enzymes are proteins that speed up the cellular processes in our bodies. Proteins are also needed for the structure and function of body tissues and organs. Proteins do not store genetic information, that is DNA's job.
Answer:
Considered "the building blocks" of living organisms, proteins direct many of the most basic functions in organisms from the transport of oxygen, to the building of tissues to the replication of DNA. These large molecules are found in all of the cells in the human body.
Explanation:
Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body’s tissues and organs.
