Which animal is most likely to have an open circulatory system?
A. Crab
B. Bird
C. Dog
D. Lizard
Answer:
A. Crab
Explanation:
The animals which are most likely to have an open circulatory system belongs to the Arthropoda Phylum of the animal kingdom. Crab belongs to this phylum. Thus, the correct option is A.
What is Arthropoda?Arthropoda is the phylum of the animal kingdom. It consists of all the invertebrate animals which have an exoskeleton, a segmented body, and paired jointed appendages. It is the largest phylum of the animal kingdom.
The distinguishing characteristics of arthropods are their jointed limbs and cuticle made of chitin, and often mineralized with calcium carbonate.
Arthropods have an open circulatory system, it means the blood does not circulate in closed blood vessels however it is pumped into a cavity called a hemocoel. The blood is also known as hemolymph as it mixes with the other interstitial fluids.
Therefore, the correct option is A.

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.

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.

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.

The Water Cycle What would most likely happen if it didn’t rain in a certain area for a long period of time?
Answer:
The air is full of water, as water vapor, even if you can't see it. Condensation is the process of water vapor turning back into liquid water, with the best example being those big, fluffy clouds floating over your head. And when the water droplets in clouds combine, they become heavy enough to form raindrops to rain down onto your head.
