The key to protecting the oceans is
preventing or reducing pollution from the land and from streams.
O reducing population growth along the coastline,
O None of these are correct.
building desalination plants to maintain freshwater supplies for coastal populations
Answer:preventing or reducing pollution from the land and from streams
Explanation: This is true because these said streams and other bodies of water can flow into the ocean
The key to protecting the oceans is preventing or reducing pollution from the land and from streams is reducing population growth along the coastline. The correct option is A.
What is pollution?Pollution is the release of potentially harmful substances into the environment. These potentially damaging compounds are referred to as pollutants.
Despite the fact that metropolitan areas are often more polluted than the countryside, pollution can nonetheless migrate to isolated locations where no one lives.
For instance, it has been demonstrated that the Antarctic ice sheet contains chemicals and pesticides. The Northern Pacific Ocean's Great Pacific Garbage Patch is a vast collection of little plastic waste.
Therefore, the correct option is A, reducing population growth along the coastline.

Describe the transportation system in plants .
Answer:
Transportation System in PlantsTransportation Of Materials In PlantsAll living organism need some method of moving substances from one part of the body to other parts of the body. For example, in living organisms food and oxygen are moved in the body to all the cells and waste materials such as carbon dioxide is taken away from them. The system of moving substances in different parts of body is called transport system. In plants, food and water are transported by bundles of tubes present in stem called phloem and xylem. In animals, food, water and respiratory gases (oxygen and carbon dioxide) and other substances are transported by blood.
In plants, transport system is not complicated as in animals. The transport system in plants consists of bundles of tubes in the stem, branches and roots. These tubes are called xylem and phloem. The main function of xylem is to transport water and dissolved minerals from the roots to rest of the plant body. While, the phloem transports the food manufactured in the leaves to all parts of the plant.

What is an advantage and disadvantage of using 4.5-7.5 pH paper?
Answer:
The correct answer would be:
Advantage: helps in finding the exact ph value with a narrower range.
Disadvantage: You don't know the exact ph value on a regular scale.
Explanation:
The pH paper is a pH paper with a color indicator that helps in determining the pH value precisely between the 4.5 to 7.5 pH range. It is accurate in comparison to other pH papers such as 0-14 paper. One no need to guess the color between the different colors from various color mixtures as it has a more precise color reading that helps in finding accurate pH value in a narrow range.
On a regular scale, it is not as accurate and one can not find the exact value as it provides a narrow range value between 4.5 to 7.5.

How is a light element like helium is formed in stars and how is a heavier element like gold formed by stars? YALL HELP ME WITH THIS PLEASE
1. Elements are not formed in stars. All elements were formed during the Big Bang and no elements have been formed since then.
2. Both light and heavy elements are formed only under very high energy conditions, such as a supernova.
3. Only light elements like helium are formed by stars. They are formed from the fusion of hydrogen nuclei. A hydrogen nucleus is made of a single proton. When protons fuse together, a new atom of helium is formed. Heavier elements like gold cannot be formed under any condition.
4. A light element like helium is formed by the fusion of hydrogen nuclei. A hydrogen nucleus is made of a single proton. When protons fuse together, a new atom of helium is formed. Heavier elements like gold form under very high energy conditions, such as a supernova, when helium atoms combine under enough successive collisions to form very heavy elements.
Answer:
its d
Explanation:
lol im pretty sure im right but i could be wrong
The theory behind the formation of helium and gold is the fusing of hydrogen nuclei results in the formation of a light element like helium. One proton makes up the hydrogen nucleus. New helium atoms are created when protons combine. When helium atoms combine through enough consecutive collisions, as occurs during a supernova, they combine to generate heavier metals like gold. The correct option is 4.
What is fusion?
Fusion is a process in which two nuclei combine to form a large, heavier nucleus. This is a nuclear reaction. Nuclear reactions are of two types, fission, and fusion.
Smaller element or lighter elements like hydrogen and helium are formed by the process of nuclear fission, in which the division of element occur from smaller nuclei.
Heavier elements are formed by the process of nuclear fusion. Where lighter elements joined to create heavier elements.
Thus, the correct option is 4.

Which of these might result from the process of natural eutrophication?
A pond becomes a meadow.
B rock breaks down into soil.
C glacier retreats to expose new land.
D nonnative species takes resources from native species.
Answer:
AaaaaaaaaaaaAaaaaaaaaaaa
Pond becomes a meadow as a result from the process of natural eutrophication.
What is eutrophication?"Eutrophication is the gradual enrichment of a body of water, or parts of it, with minerals and nutrients, mainly nitrogen and phosphorus, resulting in abundant growth of simple plant life."Excessive plant production, damaging algae blooms, a rise in the frequency of anoxic occurrences, and fish fatalities are all consequences of eutrophication. What is a meadow?"It is a piece of low ground near a river."Layers of detritus accumulate when pond plants develop, die, and disintegrate and there is an increase in the level of nutrients. Over time, these layers of decaying debris rise the pond floor. The pond floor eventually gets near enough to the bottom that emergents can grow all the way across it. The ponds develop marsh meadows as a result of this.
Hence, the correct option is A. Pond becomes a meadow.

Explain how water can be a destructive and constructive force.
Answer:
Water as a constructive force: It is involved in the deposition of sediments. It transports rock fragments, soil, and other debris at a particular area. This process eventually causes them to accumulate and form land features. Water as a destructive force: It is involved in weathering and erosion.
Explanation:
(pls mark brainliest if u can)
:)
Water can be both a destructive and a constructive force.
• The forces, which form or create an existing landform are known as the constructive forces. While the force, which tears or lowers down the surface features of the Earth are known as the destructive forces.
• Water can be considered as the constructive force as it carries sediment down the river and with the river becoming shallow, the deposition of the sediments takes place giving rise to landforms called deltas.
• On the other hand, water can also be considered as a destructive force as it takes part in processes like erosion and weathering. It breaks down and wears away the rocks and land masses.
Thus, water can be both destructive and constructive.

what are the four layers that make up the earth?
Answer: The 4 layers that make up the earth is the crust, mantle, inner core and outer core.
Explanation: The crust, which is a main layer is where we live on. Without the crust, we'll be standing on the mantle! The temperate of the crust is 392 Fahrenheit! The crust is 30 km thick. The mantle is the second layer of the earth. It's below the crust and it's hot, dense and semi-solid. It's mostly made of iron, magnesium and silicon. It can reach as hot as 1000 Celsius (1832 Fahrenheit)! It's about 2900 km thick! Anyone who standing on it will melt! The inner core is the 3rd layer. It's below the mantle and made out of liquid iron (molten iron) and nickel. It is about 5,200 Celsius (9392 Fahrenheit). Now that is hot! Hotter than a fire even a heater! The last layer is the outer core. It's made out of liquid iron and nickel, like the inner core. The outer core can be as hot as 5500 Celsius (8132 to 9932 Fahrenheit!)
Describe the positions of high and low pressure and the temperature of the land and water to explain how land breezes form.
Answer:
The air over the ocean is now warmer than the air over the land. The land loses heat quickly after the sun goes down and the air above it cools too. ... This causes a small temperature gradient between the ocean surface and the nearby land at night and the wind will blow from the land to the ocean creating the land breeze.
