Explanation:
In a lake with three trophic levels (non-native fish, zooplankton, algae), an algal bloom occurs when the small population of zooplankton declines due to the predation of the invasive fish. Which of the following describes why zooplankton are the keystone species in this scenario?
Zooplankton are the smallest of all the herbivorous marine mammals in their communities.
The small population of zooplankton have an unequal effect on the marine community.
Marine mammals depend upon the work of zooplankton to convert sunlight into food.
Zooplankton help other populations survive by keeping out other herbivores.
Answer:
The small population of zooplankton have an unequal effect on the marine community.
Explanation:
According to this question, there are three trophic levels of organism in a lake as follows: non-native fish, zooplankton, and algae. However, due to the declination in the number of zooplanktons in the lake as they were fed on by the non-native fish, the algal population increased to form a BLOOM.
This bloom of algal species can be attributed to the lack of zooplanktons, which represented the only herbivorous (plant eaters) organism in that community. Hence, their relatively small population have an unequal effect on the marine community. This means that the small population of zooplanktons caused an imbalance in the community and this is why ZOOPLANKTON is the keystone species in this scenario.

If birth rate of a population is high, what would happen to the population overtime?
Answer:
the population would increase
Explanation:
lets say your population is x,
if you keep increasing it,
x+++++,
it gets larger.
(eventually it may run out of resources and decrease in size, and then increase in size, which we know from observing the population of species in the world around us [and by logically assessing what available resources indicate])
What kinds of anthropogenic activities produce acid rain?
1 the use of refrigerants and aerosols
2 burning of fossil and plant fuels that produce carbon dioxide
3 agricultural fertilizers and methane from animal wastes
4 coal and oil power plants and automobiles
Coal and oil power plants and automobiles produce acid rain. Therefore, option D is correct.
What are acid rain and its harmful effects?Acid rain results from a chemical reaction that begins when gases in the atmosphere, such as sulfur dioxide and nitrogen oxides, are released. These molecules can go very high into the atmosphere, where they interact with oxygen, water, and other chemicals to make acid rain, another type of acidic pollution.
Calcium and magnesium, two elements that trees need for optimal health, can be destroyed by acid rain that seeps into the earth. Acid rain also releases aluminum into the soil, which reduces trees' capacity to absorb water.
Thus, coal and oil power plants and automobiles cause acid rain. Therefore, option D is correct.

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.
Answer:
Great relationship.
Explanation:
There is a great relationship between music and studying because music can increase our learning power which is very important for study. Many studies shown that music produces positive effects on a human mind and refresh the mood of the listener. Music activates both the left and right brain and the activation of both parts of the brain can increase learning power and improve memory of the student that helps in studying. Listening to music activates regions of the brain which are associated with memory, reasoning, speech, emotion, and reward.

Which of the following most correctly represents biomanipulation through the top-down model?
Addition of quaternary consumers, so that tertiary consumers can decrease
Removal of tertiary consumers, so that secondary consumers can increase
Addition of primary producers, so that secondary consumers can increase
Removal of secondary consumers, so that tertiary consumers can increase
Answer:
B. Removal of tertiary consumers, so that secondary consumers can increase.
Explanation:
Removal of tertiary consumers leads to the increase in the population of secondary consumers because tertiary consumers feeds on the secondary consumers. If the population of predators decreases, the population of prey ultimately increases in that ecosystem. Biomanipulation is the change of an ecosystem by adding or removing species, that feeds on other animals such as predators so we can say that removal of tertiary consumers leads to the increase in the population of secondary consumers.

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.
