Compare and contrast the structure and function of arteries and veins throughout the cardiovascular system.
Answer:
Arteries carry blood away from the heart, and veins carry blood towards the heart. With the exception of pulmonary blood vessels, arteries carry oxygenated blood and veins carry deoxygenated blood. Arteries have thick walls with muscle tissue. Veins have thinner walls and use valves to keep your blood flowing.

Which fossil fuel is the most widely consumed in the United States?
petroleum
natural gas
coal
peat
Answer:
Answer choice:Petroleum
Explanation:
Petroleum (crude oil and natural gas plant liquids): 28% Coal: 17.8%
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)

Venus Fly Trap
How could this special structure affect the plant’s probability of survival and/or reproduction?
Answer:
Cool Adaptation
They live in nitrogen poor environments so they have adapted to gathering additional nutrients from insects. The leaves of the Venus flytrap are wide with short, stiff trigger hairs. Once an object bends these hairs the trap will close.
Explanation:
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.
A student observes a cell under a microscope. The cell contains chromosomes that show up inside of a nucleus surrounded by an envelope. Based on the information here, the student was able to determine whether the cell was prokaryotic or eukaryotic. After making the distinction, the student could assume the cell came from certain cell types. From which potential organism was this cell-derived?
Answer:
Q.
A student observes a cell through a light microscope and correctly decides that it is a plant cell. What observation would lead to that conclusion?
It has a large, central vacuole.
The nucleus is in the center of the cell.
Ribosomes are visible.
A cell membrane is present.
Explanation:
The answer is A: I used something and it helps me if I use it I hope it helped lets be friends if you want.
The potential organism through which this cell has been derived may include plant cells, animal cells, and fungal cells.
What is a microscope?A microscope may be defined as a type of laboratory instrument that is significantly utilized in order to determine and recognize objects that are too small to be visualized by the unaided eye. The image of an object is magnified through at least one lens in the microscope.
The nucleus of the cell is the largest organelle found in the cytoplasm and it is present only in eukaryotic cells. It is in the nucleus that the chromosomes carrying the genes responsible for controlling cellular activities are found.
With the help of this information, you can conclude that the potential organism through which this specific cell was derived are known as plant cells, animal cells, and fungal cells. As they all have a eukaryotic origin.

Answer:
Differences between the Kutchicetus and the Saber-toothed cat:
The Kutchicetus had a large tail for propelling in the water, and thick blubber to stay warm.
The Saber-toothed cat had a short tail, lived in social groups, and weighed twice as much as the lion.
(They both had proportionally small hind legs compared to the rest of its body.)
Explanation:
I know the Kutchicetus had a large tail and the Saber-toothed cat didn't becuase of anatomy and reasoning (the Kutchicetus dwells in water).
I know the Kutchicetus had thick blubber and the Saber-toothed cat didn't because of anatomy and reasoning (the Kutchicetus dwells in water).
I know the Saber-toothed cat lived in social groups and the Kutchicetus didn't because the Saber-toothed cat is related to lions (lions have social groups).
I know the Saber-toothed cat weighed twice as much as the lion because of research.
I know they both have proportionally small hind legs because of anatomy. (Images)

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?
