Carbohydrates and proteins are two types of macromolecules that play critical roles in living organisms.

How carbohydrates are made?

Carbohydrates are organic molecules made up of carbon, hydrogen, and oxygen atoms. They are primarily used as a source of energy for the body, but they also serve other functions such as structural support, cell signaling, and cell recognition. Some examples of carbohydrates include sugars, starches, and fibers.

Proteins, on the other hand, are organic molecules made up of amino acids. They have a wide range of functions, including structural support, enzyme catalysis, transport, storage, communication, and defense.

One way that carbohydrates and proteins are similar is that they are both macromolecules that are essential to life. They are both made up of smaller building blocks - monomers - that are linked together through chemical bonds to form more complex structures.

One way that carbohydrates and proteins are different is that their functions are distinct. While carbohydrates are primarily used as a source of energy, proteins have a wide range of functions that are critical to the structure and function of the body.

In summary, carbohydrates and proteins are both important macromolecules with distinct functions. Carbohydrates are primarily used as a source of energy, while proteins have a wide range of functions critical to the structure and function of the body. While they share similarities as macromolecules, their functions are distinct and serve different purposes in the body.

a plant leaf is 0.04mm long. calculate the length of the image after the cell has been magnified 500 times

Answers

*To figure the length of one cell, divide the number of cells that cross the diameter of the field of view into the diameter of the field of view. For example, if the diameter of the field is 5 mm and you estimate that 50 cells laid end to end would cross the diameter, then 5 mm/50 cells = 0.1mm/cell.

Length of leaf = 0.04

After 500 times magnitude

Length of image = 0.05*500

                            = 20.00

                            = 20mm

What are leaves?Leaf is any usually flattened green outgrowth from the stem of a vascular plant. As the primary sites of photosynthesis, leaves produce food for plants, which in turn ultimately nourish and sustain all land animals.

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.

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.

Answers

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

Answers

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.
