The outer layer of the onion cell, which is a plant cell, contains cellulose, however, the human skin cell (which is an animal cell) does not contain cellulose in it. The plant cells have a rigid cell wall present around the cell membrane, which protects the cell from the outer environment and keeps it rigid. This cell wall of the plant cells is composed of the cellulose. The animal cells have no cell wall present around them, and thus, contain no cellulose.
Hence, the correct answer is 'it contains cellulose'.
The unique characteristic of the outer layer of the onion cell compared to the skin cell is that it contains cellulose.
What is cellulose?Cellulose is a complex carbohydrate that forms the cell wall of plant cells, providing rigidity and structural support. In contrast, the outer layer of a human skin cell does not contain cellulose but is composed of keratin, a protein that gives skin its strength and durability.
While proteins, carbohydrates, and selective permeability are all important components of cellular membranes, the presence of cellulose specifically distinguishes the outer layer of the onion cell. Cellulose is a major component of plant cell walls and is responsible for their characteristic shape and structure. It provides a protective barrier and contributes to the overall integrity of the cell.

Tongue, ears, and nose a part of the nervous system because B) they are sense organs that are part of the peripheral nervous system.
The tongue, ears, and nose are essential sense organs in our perception of the world, all part of the peripheral nervous system (PNS), which connects the central nervous system (CNS) to the rest of the body.
Sense Organs:
Ears: The ears contain sensory receptors that respond to sound waves, allowing us to hear. They also help with balance.Tongue: The tongue is equipped with taste buds that are sensory receptors for different tastes, such as sweet, sour, salty, bitter, and umami.Nose: The nose holds olfactory receptors that detect airborne chemicals, enabling us to smell.Function of the Peripheral Nervous System:
The peripheral nervous system (PNS) transmits sensory information from various organs to the central nervous system (CNS), where the brain processes and interprets these signals, enabling us to respond to our environment.

A researcher determined the effect that the dosage of a certain pain medication has on headaches. How would the results best be displayed? A) pie chart. B) bar graph. C) line graph. D) data table.
Answer:
Option C, line graph
Explanation:
A line graph is the best graphical tool to represent any quantity that changes continuously with time.
Here, when certain dosage of a certain medicine (which is to be tested) is given to a patient then the impacts produced by the medicine on the patient will be changing continuously. Thus, in order to capture these continuous changing values, it would be best to use a line graph.
Hence, option C is correct.

Active transport must function continuously because __________.
Active transport must function continuously because it is the movement of molecules or ions against their concentration gradient, requiring energy input. It is essential for maintaining proper cell function and homeostasis.
Explanation:Active transport must function continuously because it is the movement of molecules or ions against their concentration gradient, requiring energy input. It is essential for maintaining proper cell function and homeostasis, particularly in processes like nutrient uptake, ion regulation, and nerve impulse transmission.
For example, in the process of sodium-potassium pump in animal cells, sodium ions are actively transported out of the cell and potassium ions are actively transported into the cell, against their respective concentration gradients. This helps in maintaining the intracellular and extracellular ion balance, which is crucial for various cellular activities.
Overall, active transport is necessary to overcome the natural tendency of molecules to move from areas of high concentration to low concentration and ensure the proper functioning of cells and organisms.

The presence of different sex hormones, like estrogen and testosterone, is the key factor that accounts for the differences in essential fat between men and women.
Explanation:One of the key factors that best accounts for the differences in essential fat between men and women is the presence of different sex hormones in each gender. Hormones like estrogen in women and testosterone in men play a role in regulating fat distribution and storage. Women tend to have higher levels of essential fat, particularly in the hips and thighs, due to the influence of estrogen. On the other hand, men typically have higher levels of lean body mass and lower levels of essential fat.

are Asian elephants more closely related to Mammuthus (mammoths) or Mammuts?
Plato Answer:
Asian elephants are more closely related to mammoths because they share more nodes and branches on the phylogenetic chart. This relationship suggests a closer evolutionary ancestry. Mastodons and Paleomastodons are not the same species. There are branches from Paleomastodon and Mammuts that suggest speciation occurred. Mammuts also have common evolutionary ancestors that Paleomastodons do not have.

The brain structure that first processes visual information before it is sent to the visual cortex is the lateral geni_culate nucleus (LGN).
Light enters the eyes and is converted into electrical signals by the photoreceptor cells in the retina.
From the optic nerve these electrical signals travel along the optic nerve to the brain. The LGN, located in the thalamus, receives the signals and performs preliminary processing, such as sharpening the image and enhancing edges.
The processed signals are then relayed to the primary visual cortex (V1) located in the occipital lobe, where more complex analysis and interpretation of the visual information occurs.
In conclusion, while the optic nerve transmits the initial signals, the LGN is the first structure to process the visual information before it reaches the visual cortex for higher-level processing.

How does natural selection lead to evolution apex?
Natural selection leads to evolution by favoring individuals with traits that are advantageous for survival and reproduction, leading to these traits becoming more common in successive generations within a population.
Natural selection leads to evolution through a process where individuals with traits better suited to their environment tend to survive and reproduce more successfully than others. The traits that confer a survival or reproductive advantage increase in frequency within the population, making the population more adapted to its environment over time. If the environment changes, or if different traits become advantageous, natural selection can lead to a shift in the population's characteristics, a process known as directional selection. Conversely, when natural selection favors an intermediate phenotype, leading to a decrease in variation within a population, it is known as stabilizing selection. Variation within a population is critical for natural selection to occur; therefore, mechanisms such as genetic drift, gene flow, and mutation are also important in shaping a population's genetic diversity. Evolution is the result of the combined effects of these forces acting on a population's genetic makeup over time.
What is the major advantage of an orbiting telescope
Answer:
The answer is Orbiting telescopes can make observations to their full potential.
Explanation:
The space telescope is an artificial satellite that is used for the observation of planets, galaxies, stars, among other celestial bodies.
A telescope in space has advantages such as that it does not suffer the light pollution produced by cities, in addition to that it does not observe through the atmosphere (Earth's atmosphere adds an important distortion in the images), so its capacity always yields close of the theoretical maximum.

Why do areas north of the Arctic Circle in the Northern Hemisphere experience a polar day lasting for several months during summer?
Earth tilts 23.5 degrees above its axis from May to July. This causes the Arctic area at the North Pole of Earth to travel very close to the Sun and during this period the duration of the day increases.
What is a polar day?A natural phenomena known as the midnight sun takes place during the summer months in locations that are either north of the Arctic Circle or south of the Antarctic Circle. This occurs when the sun continues to be visible at the local midnight time.
From May through July, the Earth tilts at an angle of 23.5 degrees above its own axis in its orbit around the sun. This time of the Earth's rotation occurs when it is closest to the sun. This results in the Arctic region at the North Pole of the Earth moving very close to the Sun, which causes the length of the day to rise during this time period.
