Part A
Begin by selecting a freshwater or marine aquatic ecosystem as a model for your food web. Be specific. Choose a specific lake. Or, if you choose an ocean ecosystem, identify its geographical area and depth. Keep in mind that deep-sea organisms live in a completely different environment than surface aquatic organisms.

Next, conduct research on the following conditions in the ecosystem you chose. They influence the types of organisms that can live there.

geographical features
temperature
depth/light availability
salinity
pH
unique features that contribute to the ecosystem, such as other bodies of water that connect to it, unusual chemistry, and climate
Using the information you gathered, write a paragraph that describes conditions in the ecosystem.

Here is the article:

RED BANK, New Jersey (Achieve3000, March 22, 2021). Final exams loom and you've set up your study lair so you can bury your nose in the books and concentrate. Like a deejay seeking the exact track for the task, you thumb through your artists—Bach, Beatles, Beyoncé, Blake Shelton…your taste in music is nothing if not eclectic. So what is the perfect soundtrack for a zone of maximum mental focus and harmony? Drumroll please…

It depends.

Students from grade school to grad school love listening to tunes while hitting the books, and scientific research indicates music can have a significant impact on learning and retaining knowledge. But whether that impact helps or hinders cognitive acuity is contingent on the type of music as well as the subject being studied. In short, the best playlist for studying is highly individualized. So here's some of the science to help you cue up the best songs for the right purpose.

Music psychology—yes, it's a thing—is the study of how music influences behavior and brain function. There's little surprise that most people's brains love music and that listening to a fave song can boost and regulate mood. That's an important point when it comes to studying—research supports the idea that the more positive people feel, the better they learn and the more information they retain. In other words, music has the power to improve one's ability to concentrate and learn.

Here's where the science gets more complicated. Loud music with lyrics that make you want to lip sync interferes with the brain's "working memory." That's the neurological system that turns the text or equations you're studying into knowledge you can retrieve when needed—like during a final exam. While writing or delving into information-heavy subjects that require extensive memorization, the last thing we need are more words, ideas, or blaring beats competing for our brain's attention. For that reason, some diligent scholars swear by the soothing tones and steady mid-tempo rhythms of classical composers played at unobtrusive volumes. Favorites include Bach, Vivaldi, and Handel.

To every rule there are exceptions, though, and evidence suggests that school projects requiring brainstorming or abstract and creative thinking can benefit from music worthy of a dance party. So if you're painting for art class or coding for computer science, cranking up high-energy tunes can be a boon.

Of course, you might stick to old-school study habits, cracking the books in a quiet corner and working in silence. You can jazz up this routine with periodic "music breaks" as a reward after a quiet block of study time. But for some students—especially those stuck in noisy settings like the cafeteria, the school bus, or a room shared with a rowdy little sibling —peace and quiet is not always possible. Then, headphones providing gentle music, white noise, or nature sounds can serve as auditory shields against constant distraction.

In the end, science says that determining the best music for our study needs requires some trial and error. We should consider the subject being studied as well as such idiosyncrasies as personal learning style and individual taste. The latter is significant: Studies indicate that brain function falls flat when people are made to listen to music or sounds they don't like.

You might even devise an experiment with friends, like memorizing lists of 15 unfamiliar words while listening to music of different genres, with different tempos, at different volumes and then seeing how many you recall. You can compare your ability to activate that working memory under the influence of baroque Renaissance, pop, hip-hop, Spanish guitar, or heavy metal.

With a little investigation and a bit of science, you can reach your own conclusions. See what mix of books and beats primes your mind for optimal learning.

Is a plain the result of constructive forces, destructive forces, or both?
A plain is a result of both constructive and destructive forces.

A- Crustal deformation raises the land up, and weathering then flattens the raised area out.

B-A plain is a result of both constructive and destructive forces. Weathering keeps the plain flat over time, and deposition brings more soil and sediments in.

C- A plain is a result of constructive forces. Deposition brings in soil and sediments that spread out in a large flat area and build up large flat land.

D- A plain is a result of destructive forces. Weathering evenly wears the land down over time, which keeps the area wide and flat.
