What are the different worm phylums? Describe the differences between the three and give examples for each.

Answers

Answer 1
The three main worm phyla are flatworms, roundworms, and segmented worms. Roundworms have a digestive tube that has two openings. Segmented worms have a closed circulatory system in which blood is enclosed in blood vessels. These are important steps in the evolutionary development of animals.

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?

Answers

The right answer is 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?

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?

Different parts of the sun lit moon become visible as the moon revolves around earth

This happens because as the moon orbits earth the sun will project light towards it and the reason it seems to glow is because of the reflected light since the moon is white it reflects more light. Think of it as a day and night cycle except it’s on the moon when it becomes night on earth the part of earth facing towards the sun will be lit aka day/morning/afternoon etc
The part of the earth facing away will be dark aka night/midnight/etc.

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.

Answers

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.
