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.

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.

Why do darter species that produce larger eggs have lower gene flow among their subpopulations within a stream
Answers
Answer: There is a distinction between large and small darter species.
Explanation:
The large size darters can produce small eggs and the small size darter can produce some large eggs so the large sized larvae get hatched and emerged out from the large sized eggs and they get dispersed to the short distances in the stream. Hence, the population of large and small sized darters get genetically isolated from each others as they are incompatible for mating and producing offsprings.

The electron transporter chain is the sequence of redox reactions that occur in the mitochondrial membrane as electrons flow through different electron transporters resulting in energy production. In the attached files you will find the image with the colored structures.
What is the electron transporter chain and how does cyanid inhibit it?
The electron transporter chain is a series of molecules and proteins located in the internal mitochondrial membrane. It constitutes a series of enzymatic reactions to release and save energy for the organism’s correct functioning.
Along the chain, there are four proteinic complexes in the membrane that contain the electron transporters and the enzymes necessary to catalyze the electrons' transference from one complex to the other.
Different redox reactions occur to pass electrons from NADH along the chain.
Released energy creates a proton concentration gradient used to synthesize ATP.
Cytochrome oxidase (P450) is one of the enzymes involved in this electron transport, which ends in producing energy. It is the complex IV.
Ion cyanide is a powerful cellular poison that inhibits cellular respiration by binding to the ferric ion of cytochrome oxidase.
Cyanide-ferric binding inactivates the enzyme and blocks electron transference. The chain is interrupted, leading to no oxygen consumption and no ATP production.
Since muscles do not get to have ATP as a source of energy, they weaken.
The interruption of the electron transporter chain produces an anaerobic state that could be culminating.
In the attached files you will find the image with the colored structures. Complex IV is the one affected by cyanide.

Due to the decrease of energy at the higher levels of the pyramid, lesser organisms tend to appear at the top of the pyramid.
What is the energy pyramid?The energy pyramid shows the flow of energy in the ecosystem from one trophic level to another within an ecosystem. We know that from one trophic level to another, only about 10% of energy is transferred among biomass.
The energy that is not transferred is utilized for the metabolic activities of the organisms at that level and then lost as heat. Due to the decrease of energy at the higher levels of the pyramid, lesser organisms tend to appear at the top of the pyramid.

How do the layers of the atmosphere help to understand better the dynamics of the atmosphere and its relationship to the hydrosphere and lithosphere?
Answers
There are various layers that make up the atmosphere, and each has distinct properties and functions. Both weather generation and energy transmission take place in the troposphere, which is closest to the Earth's surface.
The stratosphere shields the Earth from damaging UV radiation along with the ozone layer. Most auroras happen in the mesosphere, where meteors burn up. Modern technology is dependent on the thermosphere, where the majority of the Earth's satellites orbit and where communication signals are sent.
The dynamics of the atmosphere and its interactions with the hydrosphere and lithosphere are better understood thanks to these layers. Foreseeing and minimising environmental problems like climate change and preserving our world, it is essential to understand the significance of each layer.

Which of the following statements BEST defines vestigial structures? :
-Structures that are different in different organisms
-Structures that are still present but currently serve little to no purpose
-Structures that are the same in different organisms
-Structures that are different between the infant and adult forms of an organism
Answers
Answer:
Structures that are still present but currently serve little to no purpose
Explanation:
Vestigial structures/organs are general defined as structures/organs that are present but poorly developed without any functional use in the present living organisms but thought to have been fully developed and functional in their ancestors.
Fully developed and functional organs gradually become less developed and non-functional across generations as the environment keeps changing and organisms found lesser use for the organs. An example includes the caudal vertebrae found in man which is kind of useless but thought to have been fully developed and functional in the ancestors of man - the monkeys.
Vestigial organs are often used as one of the morphological evidence of the evolution of living organisms.

how many moles of C atoms do you have if you have 1.23 x 10^24 atoms ?
Answers
Answer:
2.04 moles of C atoms
Explanation:
The number of moles of C atoms can be calculated using Avogadro's number, which is approximately 6.02 x 10^23 atoms per mole.
To find the number of moles of C atoms in 1.23 x 10^24 atoms, we need to divide the number of atoms by Avogadro's number:1.23 x 10^24 atoms / 6.02 x 10^23 atoms/mole = 2.04 moles
Therefore, if you have 1.23 x 10^24 atoms of C, you would have 2.04 moles of C atoms.

If 622 water molecules were removed during the synthesis of a specific polysaccharide, how many monomers were joined together to make this molecule? need help please and thank you
Answers
Answer:
623 monomers
Explanation:
In a dehydration synthesis reaction, one water molecule is removed for every bond that is created between 2 monomers.
Linking 3 monomers together would remove 2 water molecules.
Following this pattern, the number of water molecules removed will always be one less than the number of monomers that were joined together.
So, if 622 water molecules were removed, then 623 monomers were joined together.
The answer is 623 monomers.
