Do you think there’s sufficient evidence in the article to conclude that bright red leaves in the fall help protect the trees in the winter? Explain your answer.
Article:
Every autumn, traffic creeps along New England’s roads as visitors look everywhere but at the road. These tourists flock to the region as soon as leaves begin to change color from a summery green to spectacular shades of red, orange, yellow, and purple.
“Being in the Northeast during autumn is just about as good as it gets in this country,” says David Lee. He’s a botanist at Florida International University in Miami.
Lee studies leaf color, so he’s biased. But plenty of other people share his admiration. Areas of the United States with especially colorful fall displays attract thousands of leaf peepers.
Even as they “ooh” and “aah,” few people know what makes many plants blush in the autumn. Research has shown that leaves change color when their food-making processes shut off. The chemical chlorophyll, which gives leaves their green color, breaks down. This allows other leaf pigments—yellow and orange—to become visible
But “there’s still a lot we don’t know about this,” Lee says.
It isn’t clear, for example, why different species of plants turn different colors. Or why some trees become redder than others, even when they’re standing right next to each other. And no one knows exactly how global warming will alter forests and affect leaf-peeping season.
Food factory
In summer, when a plant is green, its leaves contain the pigment chlorophyll, which absorbs all colors of sunlight except green. We see the reflected green light.
The plant uses the energy it absorbs from the sun to turn carbon dioxide and water into sugars (food) and oxygen (waste). The process is called photosynthesis.
As days get shorter and colder in the autumn, chlorophyll molecules break down. Leaves quickly lose their green color. Some leaves begin to look yellow or orange because they still contain pigments called carotenoids. One such pigment, carotene, gives carrots their bright-orange color.
But red is special. This brilliant color appears only because the leaves of some plants, including maples, actually produce new pigments, called anthocyanins.
That’s a strange thing for a plant to do without a reason, says Bill Hoch of the University of Wisconsin in Madison. Why? Because it takes a lot of energy to make anthocyanins.
Why red?
To figure out the purpose of the red pigment, Hoch and his coworkers bred mutant plants that can’t make anthocyanins and compared them with plants that do make anthocyanins. They found that plants that can make red pigments continue to absorb nutrients from their leaves long after the mutant plants have stopped.
This study and others suggest that anthocyanins work like a sunscreen. When chlorophyll breaks down, a plant’s leaves become vulnerable to the sun’s harsh rays. By turning red, plants protect themselves from sun damage. They can continue to take nutrients out of their dying leaves. These reserves help the plants stay healthy through the winter.
The more anthocyanins a plant produces, the redder its leaves become. This explains why colors vary from year to year, and even from tree to tree. Stressful conditions, such as drought and disease, often make a season redder.
Now, Hoch is breeding plants for a new set of experiments. He wants to find out whether turning red helps plants survive cold weather.
“There’s a clear correlation between environments that get colder in the fall and the amount of red produced,” he says. “Red maples turn bright red in Wisconsin. In Florida, they don’t turn nearly as bright.”
More protection
Elsewhere, scientists are looking at anthocyanins in other ways. A recent study in Greece, for instance, found that as leaves grow redder, insects eat them less. On the basis of this observation, some scientists argue that red pigments defend a plant against bugs.
Leaves may turn red in the autumn to protect themselves from the sun’s ultraviolet rays.
J. Miller
Hoch rejects that theory, but Lee thinks that it might make sense. He points out that red leaves contain less nitrogen than green ones do. “It may actually be that insects avoid red leaves because they’re less nutritious,” Lee says.
However, “it’s pretty confusing at this point,” Lee admits. “People debate back and forth.”
To settle the debate, scientists will need to look at more species under more conditions, Lee says. So, he’s now researching leafy plants rather than trees. He’s especially interested in tropical plants, whose leaves turn red when they’re young rather than old.
You can do your own leafy experiments. Observe the trees in your neighborhood and keep track of weather conditions. When autumn begins, write down when the leaves change, which species change first, and how rich the colors are. You can even see anthocyanins under a simple microscope. After several years, you might start to notice some patterns.
Answer:
where the hell u gut this from
Explanation:
There’s some evidence, but not a definitive conclusion. One study focused on trees that don’t produce anthocyanins. Anthocyanins are pigments that make leaves turn red. The study said that these trees don’t absorb as many nutrients as trees with red leaves.
Another study found that insects are generally not inclined to eat red leaves on trees. There seems to be a trend that suggests that red leaves are important for the trees’ survival in the fall. This trend needs to be validated by conducting more tests.
This is the exact answer so you might wanna put in your own words. good luck! :)
How is an analogy different from a simile and a metaphor?

Subject: Nitrogen cycle
Answer: Free nitrogen comes from bacteria breaking down the nitrogen compounds which causes it to be released in the air. Fix nitrogen is from soil, plants and animals consuming it which causes it to recycle, nitrogen is cycled through: plants, soil, animals, bacteria and water and the atmosphere. I hope this helped!
Explanation:
Bacteria breaking down nitrogen compounds releases free nitrogen.Explanation:The nitrogen cycle is a process in which nitrogen is recycled through different components of the environment. Bacteria play an important role in this cycle by breaking down nitrogen compounds found in plants, animals, and soil. When bacteria break down these compounds, they release free nitrogen into the environment. This free nitrogen can then be used by other organisms like plants to create proteins and other essential molecules. So, bacteria breaking down nitrogen compounds is an important step in the nitrogen cycle.

C. Regions near the equator are highest in elevation.
D. Regions near the equator receive fewer hours of direct solar energy.
Answer: Hi! The correct answer for Question 1 is C, and for 2 is A. Brainliest?
Explanation:
Question 1: The correct answer is C. The Gulf Stream current brings warm water to the western coast of Europe, which helps to moderate the climate and keep temperatures warmer than other areas at the same latitude.
Question 2: The correct answer is A. Regions near the equator receive solar energy at a more direct angle, which results in more intense heating of the surface and warmer temperatures. This is why areas near the equator are generally hotter than areas at higher latitudes.
Answer:
Question 1: C.
Question 2: A.
Explanation:
Question 1:
Warm water is brought in by the Gulf Stream to western Europe, making the air and the climate warmer as well.
Question 2:
At the equator, the Earth is closer to the Sun, and so the energy released from the Sun is focused more on the equator than it is on other parts of the Earth.

Explanation:
1.) How does air move during sea breeze?
2.) From where does the wind blow during the land breeze?
3.) What time of the day does the sea breeze occur? (night time or day time)
4.) Which heats faster, land or sea?
5.) Compare the direction of air in sea breeze and land breeze.
PLS MARK ME AS BRAINLIEST
1.) As a result, warm air rises. Therefore, the warmer air over the land surface is rising. As the warm air over the land is rising, the cooler air over the ocean is flowing over the land surface to replace the rising warm air.
2.) a cool wind that blows from land to water. On clear, calm evenings, temperature differences between a body of water and neighboring land produce a cool wind that blows offshore. This wind is called a "land breeze".
3.) While sea breezes occur during the day, land breezes occur at night.
4.) Since land absorbs more solar radiation the land surface retains more heat as do the vegetation for energy. Thus, land surfaces warm more quickly than water.
5.) Sea breeze carries increased moisture, which it absorbs while blowing over a water body. A Land breeze is drier since it has no opportunity to absorb water from any source. Lastly, the sea breeze moves from the sea towards a land body. A Land breeze moves from land toward a water body, generally a sea or ocean.
Answer: 1.) During a sea breeze, the air moves from the sea towards the land. During the day, the land heats up faster than the sea. As a result, the air above the land becomes warmer, and it rises. The cooler air from the sea moves towards the land to replace the rising warm air, resulting in a sea breeze.
2.) During the land breeze, the wind blows from the land towards the sea. At night, the land cools faster than the sea. The air above the sea remains warmer and rises, and the cooler air from the land moves towards the sea, resulting in a land breeze.
3.) The sea breeze occurs during the daytime.
4.) Land heats up faster than water. This is because water has a higher specific heat capacity than land. Specific heat capacity refers to the amount of energy required to increase the temperature of a substance. Water requires more energy to heat up compared to land, which is why it heats up slower than land.
5.) During a sea breeze, the direction of air is from the sea towards the land. During a land breeze, the direction of air is from the land towards the sea.
