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.

Explain at least one way in which the quantity and quality of water resources have been affected by human population growth. Predict how you think the water supply will be affected by continued human population growth in the future. Support your response with evidence and scientific reasoning.
water has been polluted and many organisms living in the water will die and will affect the food chain
Explanation:
.
Water resources are getting affected by human activities as the increasing population decreases water supply and also deteriorates the water quality by decreasing the minerals.
What is the effect of overpopulation?Overpopulation is the increasing number of the population habiting the planet. It has a major negative effect on the resources as the increased population decreases the availability of the resources.
Increasing population has decreased the water resource quantity and has also decreased the quality as the pollution from overpopulation has increased the climate variation and overexploitation of the water resource.
Therefore, overpopulation has decreased the quality and the quantity of water resources.

If  you had a strand of DNA 100 base pairs long with 38 Adenine bases, how many Guanine nitrogenous bases would you have? Explain.
Answer:If a DNA double helix is 100 nucleotide pairs long and contains 25 adenine bases, how many guanine bases does it contain? Well, we have to know the base pairs for DNA first. Adenine only bonds with thymine with two hydrogen bonds, while guanine only bonds with cytosine with three hydrogen bonds. Bonding pairs can also happen vice-versa.

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

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.

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 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.

A choices:
carbon dioxide dissolves in the oceans
the shells fall to the ocean floor and become sediment
over millions of years carbonate rock limestone forms
marine organisms make calcium carbonate shells
Answer:
A
Explanation:
The carbonic acid AKA (H2C03) Decreases since the ocean water molecules start to decreased because The co2 mini carbons start to dissolve the corbon dioxide and this also happens when preasurre is maintained.
Hope This Helps!!
Carbon dioxide is the major part of the biogeochemical cycle that gets stored as carbonate rocks and gets dissolved in the oceans. It takes millions of years for a carbonate limestone rock to be formed.
What is the carbon cycle?The carbon cycle is the flow and recycling of carbon in the atmosphere, lithosphere, and hydrosphere. It takes millions of years for a carbonate limestone to be formed. The shells fall on the ocean floor and disintegrate to become sediments.
The sediments then are used by the marine organisms to make calcium carbonate. This calcium carbonate gets dissolved as carbon dioxide in the oceans and hence the cycle of the carbon goes on.
Therefore, the carbon is recycled through the atmosphere, lands, and ocean.

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?

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.
