A student is trying to model an ocean environment. What is the MOST important factor the student should add to the aquarium in order to make sure that the model is accurate?
A.starfish
B.seaweed
C.salt water
D.coral reef
Answer:
C: salt water
Explanation:
everything would be dead if there was no water
The most important factor while preparing a model of an ocean environment is Salt water. Marine ecosystems show high salinity. Thus, the correct option is C.
What is Ocean environment?Ocean ecosystems or environments are characterized by the important factors which include the availability of light, food and nutrients. Oceans have some unique properties which include high salinity, the freezing point which is slightly lower than that of fresh water, density which is slightly higher than other waterbodies, electrical conductivity which is much higher, and the slightly basic nature.
Oceans are important as they feed us, regulates the climate, and generate most of the oxygen which we use for breathing. They also serve as the foundation for much of the world's economy, supports important sectors from tourism to fisheries to the international markets.
Therefore, the correct option is C.

heyyy can someone pleasee fill in the blankss
Answer:
the moon is one-fourth the size in earth diameter (write fraction in the blank.) the distance from the moon to the earth is 385,000 earth diameters. one of the limitations of this model is that it does not describe the movement of the earth and the moon in each of their orbits. complete the sentences below to add that information to the model it takes 27 days to orbit around the earth. the moon orbits earth in a Circle

Write a hypothesis about the effects of magnetic and electric fields. Use the format of "if . . . then . . . because . . ." and be sure to answer the lesson question: "How can magnetic and electric fields be demonstrated?" Please halp me without the sample response!!!!
Well, I was taught about hypotheses differently but I'll try.
Answer: "If magnetic fields can repel and attract electric charges, then electric fields can exert a force on a positive charge because the electric field is radially outward from a positive charge and radially in toward a negative point charge."
I hope I don't mess up your grade and if I do then I'm extremely sorry.
Electric and magnetic fields can be demonstrated using electromagnets such as transformers.
What are electric fand magnetic fields?Electric fields are regions where electric force van be felt.
Magnetic fields are regions where magnetic force can be field.
If electric fields are force fields, then they can be felt from a distance by charges because force fields are felt from a distance.
If magnetic fields are directional, then north poles will repel north poles because like poles repel each other.
Therefore, electric and magnetic fields can be demonstrated using electromagnets such as transformers.

The Ring of Fire is the result of tectonic plates, huge slabs of Earth's crust that fit together like
pieces of a puzzle. The plates are constantly moving atop a layer of solid and molten rock called
the mantle. Sometimes these plates collide, move apart or slide next to each other.
How does the analogy to a puzzle help the reader to understand tectonic plates?
(A) It helps the reader to imagine how large and heavy they are.
(B) It helps the reader to consider their exact shapes and curves.
(C) It helps the reader to visualize how their edges meet and align.
(D) It helps the reader to understand that they can be lifted.
Answer:
the answers is C) It helps the reader to visualize how their edges meet and align
Plate movement results in three types of tectonic boundaries: convergent boundaries, where plates move into one another.
It helps the reader to visualize how their edges meet and align.
How can you describe the movement of plates?Plate movement results in three types of tectonic boundaries: convergent boundaries, where plates move into one another, divergent boundaries, where plates move apart, and transform boundaries, where plates move sideways in relation to one another. They move at a one to two inch (three to five centimeter) per year rate.The numerous tectonic plates constantly shift and interact. This motion changes the shape of the Earth's outer layer. This process produces earthquakes, volcanoes, and mountains.According to plate tectonics theory, pieces of the Earth's lithosphere are in slow, constant motion as a result of mantle convection currents.To learn more about : plate tectonics theory

Which of the following is an example of ecological succession?
A
New trees are now providing constant shade, and plants around them that needed sun to survive are being overgrown by shade-dependent shrubbery.
B
Marigolds and sunflowers are planted every year in a flower bed. Both flourish for a few months and then die off at the end of the season.
C
Every spring buds appear on the trees, then they turn into leaves. In the fall, these leaves change colors and die and eventually fall off the trees.
D
Tomato plants growing in a pot are replanted into the ground next to basil and other herbs. All of the plants flourish.
Ecological succession is demonstrated by the fact that nearby plants that need sunlight to flourish are now being supplanted by vegetation that requires shade. So, the correct option is A.
What is an Ecological succession?Ecological succession is the process of change in an ecological community's species composition over time. The time frame can be many decades or less or more. The cycling of nutrients like carbon, nitrogen, and sulphur is made possible by bacteria.
Ecological succession is the progressive change that occurs in a species through time as a result of the environment. Given that all biotic elements must adapt to changes in our environment, this change is both predictable and unavoidable.
The completion of this process will bring the ecosystem to equilibrium. A climax community is the one that succeeds in achieving this goal. Some species multiply in an effort to reach this balance, while others decline.
Therefore, the correct option is A.

What change in Earth's atmosphere alowed life to form?
a
Solar radiation split molecules
b
A meteor strike
c
The formation of the oceans
d
The development of an ozone layer
Answer:
D
Explanation:
the ozone layer formed and began to shield the surface of the Earth from the harmful ultraviolet light. This allowed life forms to evolve to survive on the surface of the oceans and on land and also allowed organisms who metabolize oxygen (like us!) to develop.
The change in the Earth's atmosphere which allowed life to form is the development of an ozone layer. Thus, the correct option is D.
What is the Ozone layer?The ozone layer is a region of the Earth's stratosphere which absorbs most of the Sun's ultraviolet radiations. Earth's stratosphere contains a high concentration of ozone in relation to other parts of the atmosphere, although it is still present in small amount in relation to other gases in the stratosphere.
The ozone layer in the stratosphere absorbs a big portion of the radiations from the sun, preventing it from reaching the planet's surface. Most importantly, ozone absorbs the portion of UV light called UVB. UVB is a kind of ultraviolet light which comes from the sun that has several harmful effects.
Therefore, the correct option is D.
