In this activity, you will write a description of the terrarium model you created to represent the
different systems (spheres) of Earth. Make sure to include the words geosphere, biosphere,
hydrosphere, and atmosphere in your description
Answer:Both a terrarium and Earth are closed systems. They are closed because matter, such as soil or water, cannot enter or leave. However, energy can flow into or out of the system. Just as light and heat pass through the glass of the terrarium, sunlight and heat enter and leave the Earth system through the atmosphere.

I'm stuck on this problem
Answer:
Dear people in Westfield,
your pipes contain rust because of a chemical reaction on the iron you use.The problem could be fixed by using strong plastic pipes as that takes a long time to degrade.The rust is produced when water and air mix with the iron.it takes time for the pipe to rust but that is the problem
as I said before,try using plastic pipes that are resistant to pressure.you could get them at home Depot or other pipe production company's.

You are going to create your own model that shows the movement of matter among plants, animals,
decomposers, and the environment.
Part One
You will create a 3-D model (diorama) or a 2-D model (poster) showing the movement of matter. Your
model must include the following:
• labels of plants, animals, decomposers, and the environment
• descriptions of plants, animals, decomposers, and the environment
Brainstorm ideas about what you want to create. Think about the materials you would like to use and
what you need to gather or buy. Write your list in the space provided.
You can now choose to take a picture and write a description of your model, or record a video of
yourself explaining the movement of matter. If you are writing your answers, follow the next set of
instructions.
Write a detailed description of your model and how it describes that matter is moved from plants,
animals, decomposers, and the environment.

Breathing out occurs when the respiratory muscles _____.
relax
dilate
contract
Answer:Relax
Explanation:
In exhalation, the diaphragm moves upward and the chest wall muscles relax, causing the chest cavity to get smaller and push air out of respiratory system through the nose or mouth. Every few seconds, with each inhalation, air fills a large portion of the millions of alveoli.
Describe how the kidney and bladder work together to remove waste from the body.
Answer:
The kidneys make urine by filtering wastes and extra water from blood. Urine travels from the kidneys through two thin tubes called ureters and fills the bladder. When the bladder is full, a person urinates through the urethra to eliminate the waste.
Explanation:
hope it helps
Answer:
Your kidneys filter your blood, separating toxins from nutrients. Vitamins, minerals, nutrients, and proteins return to your bloodstream. Waste products and urine move through your ureters to your bladder. Your bladder stores urine until you use the toilet.

What are coronary arteries? What are their function? How are they involved in heart disease?
Answer:
Coronary arteries supply blood to the heart muscle. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function. Also, oxygen-depleted blood must be carried away. The coronary arteries wrap around the outside of the heart. Since coronary arteries deliver blood to the heart muscle, any coronary artery disorder or disease can have serious implications by reducing the flow of oxygen and nutrients to the heart muscle. This can lead to a heart attack and possibly death.

Identify two ways in which scientists know the physical characteristics of organisms change over time.
The two ways in which scientists know the physical characteristics of organisms change over time are by examining the fossil record and comparative anatomy of these organisms.
What is comparative anatomy?One way where scientists know the physical characteristics of organisms has changed with time is through examining the fossil record. Fossils are the remains of organisms preserved in sedimentary rock over time.
The studying of fossils helps scientists to compare the physical characteristics of the organisms with modern organisms by observing the differences between them and the changes that occurred over time.
Another way is to go through comparative anatomy which involves comparing the physical structures of different organisms and identifying the similarities or differences in their anatomy that helps scientists to identify the changes and how these changes have affected these organisms.
Therefore, by examining the fossil record and comparative anatomy of these organisms help scientists to know the physical characteristics of organisms that have changed over time.

Constructed Response: Identify & describe 2 ways removing trees from a forest can affect the organisms who live there. Using the vocabulary words: Organisms, populations, communities, ecosystems, abiotic factors, and biotic factors.
Answer:
are scale tree cutting can lead to deforestation, a transformation of an area from forest to terrain with little vegetation. A biosphere is the term used to describe the combination of every ecosystem on the planet. Our biosphere is Earth. The biosphere includes all living beings and their relationships. Changing temperatures can alter which organisms can survive in an ecosystem. Plants create oxygen and absorb greenhouse gases. The destruction of trees may, therefore, encourage global warming .Biotic factors pertain to living organisms and their relationships. Abiotic factors are the non-living components of the ecosystem, including sunlight, water, temperature, wind, and nutrients. Ecologists use biotic and abiotic factors to predict population changes and ecological events. A biome is the term used to describe organisms that occupy a certain area. Biomes are determined by the primary vegetation type, the climate of the area, and the geographic location. The plants and animals in a biome share common traits that are specific to the individual biome those plants and animals inhabit.
