How are atoms and molecules related?
Answer:
Explanation:
Molecule is the general term used to describe any atoms that are connected by chemical bonds. Every combination of atoms is a molecule. A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds.
Atoms are the building blocks of molecules. A molecule is formed when two or more atoms chemically bond together.
What are they made up of?Atoms consist of a nucleus containing protons and neutrons, surrounded by electrons in energy levels or orbitals. When atoms combine, they share, donate, or accept electrons to achieve a stable electron configuration, forming chemical bonds.
These bonds can be covalent, where atoms share electrons, or ionic, where electrons are transferred between atoms. The arrangement and types of atoms in a molecule determine its chemical properties and behavior. Thus, molecules are composed of specific combinations of atoms held together by chemical bonds.

New forms of drug-resistant bacteria can evolve quickly because
A
when a drug kills most of the bacteria, the ones left to breed are those that have a natural resistance to the drug.
B
when scientists genetically engineer bacteria they use natural selection.
C
scientists use extinction to selectively breed bacteria.
D
a drug causes mutations in the bacteria, leaving only mutated bacteria left to breed.
Misuse, abuse, and inadequate infection control and preventive practices all speed up the development of antibiotic resistance. At all societal levels, actions can be made to lessen the effects and contain the spread of resistance. Thus, option A is correct.
What drug-resistant bacteria can evolve quickly?The experiment demonstrates how simple and rapid it is for bacteria to develop resistance. Resistance levels rose more than 1000-fold in just 11 days, according to Professor Kishony.
Antibiotic usage is the primary contributor to antibiotic resistance. When people take antibiotics, some bacteria are killed, but resistant germs can survive and even multiply.
The incidence of resistant bacteria rises with antibiotic use. The more frequently we take antibiotics, the more likely bacteria are to evolve resistance to them.
Therefore, Within two to three years, new antimicrobial resistance can spread widely. For bacteria that can be selected as both benign commensals and harmful hospital acquired illnesses, resistance issues are particularly serious.

Which environment will experience the LEAST amount of change over time?
A. an ecosystem with a climax community
B. an ecosystem that is in secondary succession
C. an ecosystem that is in primary succession
D. an ecosystem with only pioneer species
Answer: D
Explanation: the pioneer species is the first species to live in an environment
An ecosystem with a climax community will experience the least amount of change over time. Therefore, option A is correct.
Why climax community ecosystem experience the least amount of change?A climax community is a stable community of plants and animals that has reached a state of equilibrium with its environment. In such a community, the number of species and their relative abundance tend to remain relatively constant over time, barring any major disturbances such as fire or human intervention.
In contrast, ecosystems in primary and secondary succession are undergoing significant changes as they transition from bare rock or disturbed land to a stable, self-sustaining community. Ecosystems with only pioneer species may also experience significant changes over time as more complex plant and animal communities develop.
Therefore, option A is correct.

Choose one region on the world map. How does the climate their differ during El Niño and La Niña?
Answer:What are El Niño and La Niña?
El Niño and La Niña are opposite phases of a natural climate pattern across the tropical Pacific Ocean that swings back and forth every 3-7 years on average. Together, they are called ENSO (pronounced “en-so”), which is short for El Niño-Southern Oscillation.
The ENSO pattern in the tropical Pacific can be in one of three states: El Niño, Neutral, or La Niña. El Niño (the warm phase) and La Niña (the cool phase) lead to significant differences from the average ocean temperatures, winds, surface pressure, and rainfall across parts of the tropical Pacific. Neutral indicates that conditions are near their long-term average.
Maps of sea surface temperature anomaly in the Pacific Ocean during a strong La Niña (top, December 1988) and El Niño (bottom, December 1997). Maps by NOAA Climate.gov, based on data provided by NOAA View. large versions La Niña | El Niño
What happens during El Niño and La Niña?
During El Niño, the surface winds across the entire tropical Pacific are weaker than usual. Ocean temperatures in the central and eastern tropical Pacific Ocean are warmer than average, and rainfall is below average over Indonesia and above average over the central or eastern Pacific.
Rising air motion (which is linked to storms and rainfall) increases over the central or eastern Pacific, and surface pressure there tends to be lower than average. Meanwhile, an increase in sinking air motion over Indonesia leads to higher surface pressure and dryness.

Anomalous ocean warming in the central and eastern Pacific (orange) help to shift a rising branch of the Walker Circulation to east of 180°, while sinking branches shift to over the Maritime continent and northern South America. NOAA Climate.gov drawing by Fiona Martin.
During La Niña, it’s the opposite. The surface winds across the entire tropical Pacific are stronger than usual, and most of the tropical Pacific Ocean is cooler than average. Rainfall increases over Indonesia (where waters remain warm) and decreases over the central tropical Pacific (which is cool). Over Indonesia, there is more rising air motion and lower surface pressure. There is more sinking air motion over the cooler waters of the central and eastern Pacific.

Generalized Walker Circulation (December-February) anomaly during La Niña events, overlaid on map of average sea surface temperature anomalies. Anomalous ocean cooling (blue-green) in the central and eastern Pacific Ocean and warming over the western Pacific Ocean enhance the rising branch of the Walker circulation over the Maritime Continent and the sinking branch over the eastern Pacific Ocean. Enhanced rising motion is also observed over northern South America, while anomalous sinking motion is found over eastern Africa. NOAA Climate.gov drawing by Fiona Martin.
Between the warm phase (El Niño) and cool phase (La Niña), scientists describe conditions as “ENSO-neutral.” Neutral means that the temperatures, winds, convection (rising air), and rainfall across the tropical Pacific are near their long-term averages.

Explanation:
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! :)
