Answer: Im sorry i dont kno
Explanation:
Based on the observations of the sand dune model with a fan, the conclusions provided in the chart are incorrect. In reality, each statement's opposite is true.
What is Sand dune?A sand dune formed by wind or water flow is known as a sand dune. When there is a lot of loose sand present and the wind or water is powerful enough to shift the sand grains, sand dunes emerge. Beaches, deserts, and some riverbeds all contain sand dunes.
Based on the observations in the provided example, the following inferences are correct:
Landforms can be eroded by wind.Sand can be moved by wind and dumped elsewhere, altering the size and shape of landforms.Sand and other materials are transported from one location to another by wind, which is a significant agent of sediment transport.Materials can weather and degrade in the wind through abrasion and deflation.Therefore, the conclusions given in the chart are false based on the observations of the sand dune model.

The cell walls of a plant consist mostly of cellulose, a carbohydrate, which provides a strong structure. The cell membrane gets its structure primarily from lipids, and embedded proteins allow for material transport.
Which of the following elements would be found in the LOWEST amounts in both the cell wall and cell membrane?
Answer:
The answer is Sodium (Na+)
Explanation: The cell wall of the plant cells is composed mostly of cellulose, which is a polysaccharide composed mostly of carbon, hydrogen and oxygen, and it has a linear and complex configuration. On the other hand, the cell membrane is composed of phospholipids, in the configuration of lipid bilayer. Phospholipids are molecules that have a polar head (where phosphorus is found) and a hydrophobic (lipid) tail. Carbon and hydrogen are also found in non-polar or hydrophobic tails. Sodium on the other hand is an Ion (Na +) that is mainly dissolved in water, so it is expected to find it mostly in the lumen or outside the cell. Sodium plays an important role in the transport of some substances through the cell membrane, but their amounts cannot be very high, because of being very concentrated, this can cause plasmolysis or cell destruction

Explanation:
How would the loss of predators contribute to deforestation in the
jungle?
Answer:
Predators eat prey. When they do so, they are keeping the population or number of prey in check. Now, a lot of prey are either herbivores or omnivore, meaning plants are in their diet. If there were to be no predators, an absurd overpopulation of prey would arise. This would cripple the growth of young trees by the prey feeding on them, and overall would over-run their habitat, making the food sources scarce. When the food source gets so low they will die out or continue to move on to other surrounding areas and create the same problems.

How do catalysts affect a chemical reaction?
lower activation energy
provide activation energy
increase activation energy
lose activation energy
Answer:
lower activation energy
brainliest is appreciated
Explanation:
Catalysts make such a breaking and rebuilding happen more efficiently. They do this by lowering the activation energy for the chemical reaction. Activation energy is the amount of energy needed to allow the chemical reaction to occur. The catalyst just changes the path to the new chemical partnership.2

What is the function of the cytoplasm?
Answer:
Thay are:
1. The cytoplasm function to support and suspend arganelles and cellular molecules.
2. The cytoplasm helps to move materials,such as hormones, around the cell and also dissolves cellular waste.
Answer:
Cytoplasm FunctionOne of the major functions of cytoplasm is to enable cells to maintain their turgidity, which enables the cells to hold their shape. Other functions of cytoplasm are as follows:
The jelly-like fluid of the cytoplasm is composed of salt and water and is present within the membrane of the cells and embeds all of the parts of the cells and organelles.The cytoplasm is home to many activities of the cell as it contains molecules, enzymes that are crucial in the break down of the waste.The cytoplasm also assists in metabolic activities.Cytoplasm provides shape to the cell. It fills up the cells thus enabling the organelles to remain in their position. The cells, without cytoplasm, would deflate and substances will not permeate easily from one to the other organelle.A part of the cytoplasm, the cytosol has no organelles. Rather, the cytosol is enclosed by matrix boundaries that fill up the cell section which does not hold the organelles.The whole cellular content of a living cell is called protoplasm. The cytoplasm, nucleus and all other living components of the cell together make up the protoplasm of a cell.

Light that Moves and Molds Gels
Pitt research team demonstrates gels that can be moved, controlled by light
PITTSBURGH—Some animals—like the octopus and cuttlefish—transform their shape based on environment, fending off attackers or threats in the wild. For decades, researchers have worked toward mimicking similar biological responses in non-living organisms, as it would have significant implications in the medical arena.
Now, researchers at the University of Pittsburgh have demonstrated such a biomimetic response using hydrogels—a material that constitutes most contact lenses and microfluidic or fluid-controlled technologies. Their study, published in Advanced Functional Materials, is the first to show that these gels can be both reconfigured and controlled by light, undergoing self-sustained motion—a uniquely biomimetic behavior.
Together with Olga Kuksenok, research associate professor in the Swanson School, Balazs experimented with a newer type of hydrogel containing spirobenzopyran molecules. Such materials had been previously shown to form distinct 2-D patterns on initially flat surfaces when introduced to varying displays of light and are hydrophilic in the dark but become hydrophobic under blue light illumination. Therefore, Balazs and Kuksenok anticipated that light could be a useful stimulus for tailoring the gel’s shape.
Using computer modeling, the Pitt team demonstrated that the gels “ran away” when exposed to the light, exhibiting direct, sustained motion. The team also factored in heat—combining the light and local variations in temperature to further control the samples’ motions. Controlling a material with light and temperature could be applicable, Balazs said, in terms of regulating the movement of a microscopic “conveyor belt” or “elevator” in a microfluidic device.

“Imagine an apartment with a particular arrangement of rooms all in one location,” said lead author Anna Balazs, Pitt Distinguished Professor of Chemical and Petroleum Engineering in the Swanson School of Engineering. “Now, consider the possibility of being able to shine a particular configuration of lights on this structure and thereby completely changing not only the entire layout, but also the location of the apartment. This is what we’ve demonstrated with hydrogels.”

describes lipids in water
Answer:
Ok
Explanation:
Molecules such as proteins, nucleic acids, and carbohydrates have an affinity for water and are called hydrophilic (“water-loving”). Lipids, however, are hydrophobic (“water-fearing”). Some lipids are amphipathic—part of their structure is hydrophilic and another part, usually a larger section, is hydrophobic. Hope this helped

And if u move the decimal to the right is it positive(or when u move it to the right its negative?)?
Answer:
oh I can try my best to help you so it depends on the whole number you can move the decimal to the left or to the right but if the whole number is positive then it would still be positive just have less value when doing it to the left and it would have more value when moving it to the right .so think of it as moving it to the left as dividing/subtracting and moving it to the right as multiplying/adding hope I helped!! :'))
