Each year, volunteers of the local WaVE (Waves are Very Exciting) group hold an annual meeting for new members. This year you have been asked to give the introductory speech at the meeting in which you will explain to members the importance of waves in the world. Your two-paragraph speech should include the following:
• general properties shared by all waves.
• how waves affect matter at the macroscopic and particle levels.
• the difference between the three types of mechanical waves.
The speech should be appropriate for a formal audience, and must include a topic statement, transition phrases, and the science vocabulary from the word bank.
WORD BANK
longitudinal wave
mechanical wave
medium
surface wave
transverse wave
wave
wave cycle
wave pulse
Speech on wave includes:
The pace at which an object's position changes as perceived from a particular point of view and as measured by a particular unit of time (for example, 60 km/h northbound) is defined as its velocity. Velocity is a fundamental concept in kinematics, the branch of classical mechanics that deals with the motion of bodies.In order to be defined, the physical vector quantity known as velocity needs to have both a magnitude and a direction. Speed is a coherent derived unit whose quantity is measured in meters per second (m/s or m/s1) in the SI. Speed is the scalar absolute value (magnitude) of velocity (metric system). "5 meters per second," for example, is a scalar as opposed to "5 meters per second east," which is a vector.
In a macroscopic object, each particle's wave is absorbed and combined with the waves of other particles to create a single wave that serves as a representation of the whole entity. The observation of this object causes the wave function to instantaneously collapse.When you know anything about the world around us, some wave somewhere experiences a collapse.
In other words, if an object can be seen, it does not have a wave function.
Visualize your thing as a long string for the transverse wave. You hold the other end while securing the other end to a tree to exert pressure on the string. Then, when you move the end of the string you are holding up and down, the thread is seen sliding down in the direction of the tree. As a result, the medium (the string) moves perpendicular to or transverse to the direction of motion. In other words, a transverse wave is being created by you!
Compression waves and pressure waves are additional terms for longitudinal waves. When a wave travels through space in a longitudinal direction, the medium also moves in that direction. To further understand this, picture a liquid in a tube with a piston or plunger at one end and a stiff wall at the other. The liquid (the medium) travelling down the tube experiences variations in pressure and displacement when the piston is compressed.
Surface waves cross the gap between two dissimilar media. Examples include seismic waves, which often result from earthquakes, or ocean waves. Because the molecules in the medium spin as a result of surface waves, neither transverse Transverse, which literally means "across," usually refers to a path or plane that is neither longitudinal nor perpendicular to a part's axis. They can be thought of as having both transverse and longitudinal components, though. Surface waves' electromagnetic equivalent, ground waves, is addressed in another section of this book.

The additional organelles would need to be shown on this diagram to demonstrate that the cell can produce proteins are: ribosomes, rough ER, Golgi apparatus and vacuoles.
How are proteins produced?Proteins are formed by ribosomes that are going to make them from amino acids, this is done from a copy of DNA that comes from the nucleus, which is going to contain the information of the protein, each protein has your own DNA copy. Then when the ribosome has already formed the protein, it will be expelled through vacuoles and will move towards the golgi apparatus where it will finish modifying the protein and then it will be released through vacuoles into the environment. Ribosomes are found in the thick endoplasmic reticulum.

Dendrites send information from other dendrites. The cell body _____ that information and sends a signål through the _______ to other dendrites. Then, when the signal is received by other neurons. Then, those neurons ______
A neuron's (nerve cell) dendrites are its outgrowths, which are where it receives signals (information) from other neurons. Electrochemical signals are used to transmit information from one neuron to another.
The portion of a neuron's body that houses the nucleus and regulates cell activity is referred to as the cell body or soma.
The axon, which transmits information to other neurons, and the dendrites, which carry information to the neuron, are connected by the cell body. The dendrites transmit signals to the cell body when a neuron receives information from another neuron. Depending on the signal's strength, the cell body may then deliver the information to the axon.

B. Taking a picture of Earth's interior is impossible.
C. Earth's interior is very hot and too dangerous to study directly.
D. Earth's interior layers formed too long ago to observe directly.
The geochemical and geodynamic models explain the Earth's interior and structure from different points of view. Both of them are equally valid and useful. Option B. Taking a picture of the Earth's interior is impossible.
What are the models of the Earth's interior?
Two models explain the interior structure of the Earth according to its chemical composition (mineral nature) and the physical behavior of the materials composing it (seismic wave propagation).
The first one is the geochemical model. It divides the Earth's interior into the core, the mantle, and the cortex.
The second one is the geodynamic model, which divides the Earth's interior into endosphere, mesosphere, and lithosphere.
Both of them are equally correct and closely related to each other. Using one or the other while carrying out research will depend on the goals of the research.
These models are a great way to interpret the Earth' interior and a solution to the fact that no real image can be taken as a whole to explain its structure.

B. Using tools or measurements to collect data
C. Asking questions and being curious about the natural world
OD. Analyzing data and observations to form conclusions
SUBMIT
Option D: An example of using scientific thinking to make inferences is analyzing data and observations to form conclusions.
Scientific thinking is a step included in a scientific investigation. Scientific investigation is a plan to observe different aspects of nature, ask questions, and draw possible answers. Steps to scientific investigation involve making observations, asking a question, forming hypotheses, testing hypotheses, and concluding. The last and most important step is communicating the conclusions with others. This allows others to test what was produced in a scientific investigation and whether the claims are true or not.
Conclusions are formed on the basis of data and observations made in a research. Any hypothesis that a scientist claims needs to provide evidence. None of the evidence can be true wholly. That's why, conclusions are made on the basis of their studies and evidence for those studies. Another scientist may find another result that may not support the previous hypotheses and thus the hypothesis may be proved wrong. The more evidences for a hypotheses are provided, the more chances the conclusion made was true.
