What types of waves are sound and light? Explain how they would be classified based on the direction of their particle movement and whether they can move through a vacuum. Use details to support your answer.
Answer:
Longitudinal versus Transverse Waves versus Surface Waves
One way to categorize waves is on the basis of the direction of movement of the individual particles of the medium relative to the direction that the waves travel. Categorizing waves on this basis leads to three notable categories: transverse waves, longitudinal waves, and surface waves.
A transverse wave is a wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves. Suppose that a slinky is stretched out in a horizontal direction across the classroom and that a pulse is introduced into the slinky on the left end by vibrating the first coil up and down. Energy will begin to be transported through the slinky from left to right. As the energy is transported from left to right, the individual coils of the medium will be displaced upwards and downwards. In this case, the particles of the medium move perpendicular to the direction that the pulse moves. This type of wave is a transverse wave. Transverse waves are always characterized by particle motion being perpendicular to wave motion.
A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves. Suppose that a slinky is stretched out in a horizontal direction across the classroom and that a pulse is introduced into the slinky on the left end by vibrating the first coil left and right. Energy will begin to be transported through the slinky from left to right. As the energy is transported from left to right, the individual coils of the medium will be displaced leftwards and rightwards. In this case, the particles of the medium move parallel to the direction that the pulse moves. This type of wave is a longitudinal wave. Longitudinal waves are always characterized by particle motion being parallel to wave motion.
A sound wave traveling through air is a classic example of a longitudinal wave. As a sound wave moves from the lips of a speaker to the ear of a listener, particles of air vibrate back and forth in the same direction and the opposite direction of energy transport. Each individual particle pushes on its neighboring particle so as to push it forward. The collision of particle #1 with its neighbor serves to restore particle #1 to its original position and displace particle #2 in a forward direction. This back and forth motion of particles in the direction of energy transport creates regions within the medium where the particles are pressed together and other regions where the particles are spread apart. Longitudinal waves can always be quickly identified by the presence of such regions. This process continues along the chain of particles until the sound wave reaches the ear of the listener. A detailed discussion of sound is presented in another unit of The Physics Classroom Tutorial.

In the United States, there has been an increase in the number of people infected by mosquito-spread diseases that were previously found only in countries south of the United States. Scientists want to investigate the cause of the increase in mosquito-spread diseases. Scientists have predicted that the mosquitos carrying disease have moved further north as global temperatures have increased.
Which questions would help investigate how the new mosquitoes are affecting the ecosystems of the United States? ***Select all that apply***.
A. Have the natural predators to the mosquitoes also migrated north?
B. Are places in the United States using more pesticides to kill the new mosquitoes? If so, how are these pesticides impacting others in the ecosystems?
C. How have the food webs in the United States changed as a result of the new mosquitoes?
D. What types of organisms are preying on the mosquitoes in their new habitats?
E. How much money has been spent to fight the diseases caused by these mosquitoes across the globe?
GIVING BRAINLIEST
Answer:
#1: No
#2: Yes due to the fact that as more spread the more that they would want to prevent people from getting sick from being bitten.
#3: No, these mosquitoes would only be carrying a disease, not a different type a breed.
#4: Other bigger bugs or small animals who would normally eat bugs.
#5: Thousands if not millions of dollars across the world due to the fast spread of them moving to a new area.

I need help!
You're in a town called Watertown. You need to save it from water pollution. They don't have any money! SO, they need you to use stuff from your house (imagine). Make a design that shows how to stop it from happening. How could you clean the water in your model using the materials around the house?
PLEASE HELP ME! I NEED HELP!! IF YOU GOT ONE, MAKE A QUESTION AND ILL GIVE YOU ALL MY POINTS.
Answer: You can clean the water pollution by the water bottle activity.
Explanation:
You can do the water bottle filteration. From your house, you should find a large soda bottle or water bottle. YOu layer it with sand and gravel at the bottom. Line the top of the bottle with a coffee filter. This will allow for a natural filtration system.
You can find this on many science experiments websites because it is a common science fair project.
Search tool would be: homemade water filter

Answer:
Another factor can be photosynthesis.
Explanation:
During photosynthesis, plants would give off some oxygen as a waste product. The carbon dioxide would then move from the air into the leaves of the plants through tiny openings in the plant's leaves. Oxygen moves out of the plant's leaf through the same openings.

E. How much money has been spent to fight the diseases caused by these mosquitoes across the globe?
Are places in the United States using more pesticides to kill the new mosquitoes? If so, how are these pesticides impacting others in the ecosystems?
Thus, An ecosystem is a region where different species of plants, animals, and other organisms coexist in harmony with the environment, including the climate and geography.
An ecosystem is a place where several types of living things coexist to create a bubble of life, including plants, animals, and other species. Ecosystems are made up of both biotic (or alive) and abiotic (or nonliving) components. Plants, animals, and other living things are considered biotic factors. Rocks, temperature, and humidity are examples of abiotic variables.
In an ecosystem, every component is dependent on every other component, either directly or indirectly.
Thus, Are places in the United States using more pesticides to kill the new mosquitoes? If so, how are these pesticides impacting others in the ecosystems?

Mutaulism

Parasitism
Competition

Answer:
Another reason is that Zebras and Antelope love the open African savannas – in comparison to Kudus or other antelopes that prefer the thicker bush. Being out in the open obviously makes these two antelope species very vulnerable – therefore they are teaming up and are best buddies.

3. What is a PRO of asexual reproduction?
4.What kind of organisms are corals? What adaptations do they have to help them eat?
5.Why are adaptations important for a species?
Answer:
1. Bears are highly intelligent, wide-ranging animals and can therefore suffer particularly badly in captivity. Many bears kept in zoos, circuses and road-side “shows” display abnormal behaviours, including repetitive pacing, swaying from side to side or bar-biting.
Bear Conservtion campaigns to end the confinement of bears for ‘entertainment’. We aim to address five main areas; circuses and shows, zoos and collections, bear farms, dancing bears, and bear baiting. Follow the links below to find out more. See also our separate section on Sanctuaries.
