Some of the wave's energy stays in the medium itself. This is because the energy of a wave depends on its amplitude and frequency of it.
Where does the energy of a wave go?The amount of heat that is constructed or produced by the breaking wave is so imperceptibly small that I never could have imagined that that was what was happening, but it does make perfect sense. The energy goes from wind to water to sound and heat.
The components of the energy are Kinetic and Potential. The total mechanical energy of the wave is the sum of its kinetic energy and potential energy. The energy of the wave correspondingly absorbed via the medium in which is significant travels a specific distance.
Therefore, some of the wave's energy stays in the medium itself. This is because the energy of a wave depends on its amplitude and frequency of it.

Which geographic features are associated with a divergent boundary?
Answer:
Tectonic plates.
Explanation:
At the divergent boundaries, two plates move away from each other and the space produced by this spacing is filled by a new magmatic crust material. Thus, the divergent limit is constructive, since it allows the expansion of the ocean floor and the consequent formation of a new lithosphere.
According to this concept, we can say that the geographical features that are associated with a divergent boundary are the tectonic plates.

Which of the following is the best description of the fluid mosaic model? A stationary triglyceride bilayer with fluid proteins. A stationary phospholipid bilayer with proteins that change positions. A fluid triglyceride bilayer with embedded proteins. A fluid phospholipid bilayer with embedded proteins.
The fluid mosaic model is a description of the cell membrane structure, which includes a fluid phospholipid bilayer with embedded proteins that can move and change positions.
Explanation:The best description of the fluid mosaic model is a fluid phospholipid bilayer with embedded proteins. The model describes the structure of the cell membrane, which is composed of a double layer of phospholipids with proteins embedded within it. The phospholipids can move laterally within the bilayer, hence the term "fluid", while the proteins can also move and change positions. This model helps to explain the dynamic nature of the cell membrane and its role in regulating the movement of substances in and out of the cell.
According to this model, the cell membrane is composed of a dynamic and flexible phospholipid bilayer in which various proteins are embedded. The phospholipid molecules have hydrophilic (water-loving) heads and hydrophobic (water-repelling) tails, arranging themselves in a bilayer with the heads facing outward and the tails facing inward.
The embedded proteins in the membrane can move laterally within the bilayer, and they have diverse functions, including transport, signaling, and structural support. This dynamic nature of the cell membrane allows it to adapt to changing conditions and perform its essential roles in cellular processes.

A family has two male children one brother has a straight thumb a straight thumb while the other brother has a bent thumb what causes this difference
Answer: Due to different alleles.
Explanation:
Every trait is encoded by a particular gene and each gene has various alternative forms. These alternative forms of a given gene are known as alleles.The alleles that encode the shape of the thumb are of two types - one is the S allele which encodes a straight thumb and is dominant in nature whereas the second allele is the h allele which encodes for the bent thumb and is recessive in nature.Thus, the two children have different thumbs as they have received different alleles from their parents.8. If you were given a slide containing living cell from an unknown organism, how would you identify the cells as either plant or animal?
Answer:
The cell can be identify by looking at their shape.
Explanation:
Plant cells have cell walls outside the cell membrane. Animals cells doesn't have any cell wall.
The shape of plant cells are generally square or rectangle. The slide contains cells with square shape cells, that means the cells are plant cells. If the slide has oval or round shape cells , the cells are animal cells. Large vacuoles are visible only under the slides of plant cells.
Thus, the difference on the basis of cell shape and vacuoles can be used to identify plant and animal cells.
Cells are the living entities, which are the structural, basic, and functional units of all living beings. The eukaryotic cell can be divided into plant cells and animal cells.
The difference between the plant cell and animal cell are:
An animal cell is a eukaryotic cell, with membrane-bound organelles and an eccentric nucleus. The animal cell consists of the cell organelles centrosomes, lysosomes, ribosomes, Golgi apparatus, mitochondria, cytoplasm, and cell membrane. The plant cell is a eukaryotic cell with an eccentric nucleus and comprising the organelles like cell walls, chloroplasts, vacuoles, and other membrane-bound organelles.

Which of the following is critical in developing a science question?
Developing a science question requires prioritizing testability and reliance on observable phenomena, ensuring meaningful contributions to scientific inquiry and knowledge generation. The correct answer is C. Ensuring it is testable and based on observable phenomena.
In developing a science question, the critical aspect lies in its ability to contribute to scientific inquiry and understanding. It should not merely conform to popular trends or aim for complexity to impress.
Instead, the question should prioritize testability and reliance on observable phenomena.
Firstly, a scientifically rigorous question must be testable. This means that it should be possible to design experiments or gather data that can provide evidence to support or refute hypotheses related to the question.
Testability ensures that the question leads to empirical investigation, which is fundamental to the scientific method.
Without the ability to test a question, it remains speculative and cannot contribute meaningfully to scientific knowledge.
Moreover, a science question should be based on observable phenomena.
This means that it should be grounded in real-world observations or measurable phenomena that can be studied systematically. By focusing on observable phenomena, scientists can gather empirical evidence to support their hypotheses and conclusions.
Observable phenomena provide the basis for constructing scientific models and theories that accurately describe and predict natural phenomena.
Contrary to the options presented, aligning with current popular trends or emphasizing complexity and technical jargon may detract from the scientific validity of a question.
Popular trends may be fleeting and not necessarily grounded in scientific inquiry, while complexity for the sake of impressiveness may obscure the clarity and coherence of the question.
Additionally, inundating a question with technical terms can alienate audiences and obscure the underlying concepts.
In summary, the critical aspect in developing a science question is ensuring it is testable and based on observable phenomena. This ensures that the question contributes meaningfully to scientific inquiry and facilitates the generation of reliable knowledge.
The correct answer is C. Ensuring it is testable and based on observable phenomena.

If you were to examine the profile of a typical stream, you would probably find that the gradient is _____.
If you were to examine the profile of a typical stream, you would probably find that the gradient is steeper at the headwaters (the upper part of the stream).
What is the gradient of a stream?The gradient of a stream refers to the rate at which the stream bed slopes or descends over a given distance, usually measured in feet per mile or meters per kilometer. It represents the change in elevation of the stream over a horizontal distance and is an important factor that influences the flow and behavior of the stream.
If you were to examine the profile of a typical stream, you would probably find that the gradient is steeper at the headwaters (upper part of the stream) and gradually decreases as the stream approaches its mouth (lower part of the stream).
This is because the water at the headwaters has a higher potential energy due to gravity and is able to flow more quickly downhill, while the water at the mouth has a lower potential energy and flows more slowly.

Why do biologists assign each organisms a universally accepted name?
Scientific names are more useful because they refer to the same, identical organism regardless of place.
What organisms are a universally accepted name?In theory, every recognized species on Earth have a two-part scientific name. This system is known as “binomial nomenclature”.
These names are important because they make it possible for people all around the world to communicate clearly about different animal species.
Scientists give each organism a name that is well known because the use of common names can be confusing (also known as a scientific name).
Common names differ throughout languages and even between areas of the same country. Additionally, various species could use the same common name.

A plant dying after being exposed to poison represents a physical change true or false???
The statement is false because a plant dying from exposure to poison is an example of a chemical change, as it involves a change in the plant's chemical composition, not just a physical alteration.
Explanation:The question: A plant dying after being exposed to poison represents a physical change, true or false?. False. This statement is false because a plant dying from poison represents a chemical change, not a physical one. This is due to the alteration of the chemical structure within the plant as a result of the poison, which causes damage or death to the plant. For instance, when a toxic agent like poison interacts with a plant's biological systems, it can lead to a series of biochemical reactions that ultimately cause the plant cells to die, a process that involves a change in the chemical composition of the plant.
Additionally, the terms chlorotic (yellowing of leaves due to lack of chlorophyll) and necrotic (dead tissue) refer to conditions that are symptomatic of underlying chemical changes within the plant tissues. Therefore, exposure to poison and the resulting damage is a clear example of a chemical change.
Can you die from drinking too much water? Explain using evidence about osmosis and cells.
Drinking too much water too quickly can lead to water intoxication. This causes the dilution of electrolytes, an osmotic imbalance in cells, and potentially fatal cell swelling. Osmosis drives water into or out of cells to balance solute concentrations, and severe disruption can be lethal.
Explanation:Yes, you can die from drinking too much water; this condition is known as water intoxication or hyponatremia. When you drink excessive amounts of water in a short period, it dilutes the sodium in your bloodstream. Cells must maintain a specific osmotic pressure to function correctly. Water intoxication occurs when the dilution of electrolytes in your blood causes an imbalance, leading to an influx of water into your cells. Cells swell as the water moves inward to balance the concentration of solutes on either side of the cell membrane due to osmosis. This swelling can lead to dangerous swelling of the brain, among other complications.
In the case of drinking a hypotonic solution like distilled water in vast amounts, you're introducing a fluid with lower osmotic pressure into your body. Our body cells, which have a higher solute concentration compared to the hypotonic solution, will draw water in to achieve equilibrium, potentially causing the cells to expand and rupture (hemolysis). Conversely, drinking a very salty solution like seawater, which is hypertonic, would cause your body cells to lose water and possibly shrink (crenation). Osmotic balance is critical for cells to function properly, and severe disruption can lead to cell and tissue damage, and ultimately death.
