The appearance of the substance before the phase change can be described as Melting, Vaporization, Sublimation, Condensation.
Melting:
When a substance converts from the solid to the liquid.
Vaporization:
The substance changes from a liquid to a gas.
Condensation:
When a substance converts from a gas to a liquid.
Sublimation:
When a substance converts directly from a solid to a gas without going through the liquid phase.
Therefore, the appearance of the substance before the phase change can be described as Melting, Vaporization, Sublimation, Condensation.

After Michelle went on vacation for two weeks, she came home to find her potted plants had turned brown and died. The soil was very dry. While Michelle was away, she kept the curtains and windows closed and did not have a neighbor come by to water her plants.

How do you think the formation of fossils in sedimentary rock disrupts or alters the process of sedimentary rock formation? In other words, how does the formation of a fossil fit into the process of sedimentary rock formation? Defend your answer.
Answer:
I can't help sorry
Explanation:
Answer:
Sedimentary rocks are the product of 1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock. The latter two steps are called lithification.

1. write a sentence that describes how the food changes in the stomach.
2. write a sentence that describes how the food changes in the small intestine.
3. explain what happens to digested food in the small intestine
4. write a sentence that describes what happens to digested food in the cell.
Answer:1.Once filled with food, the stomach grinds and churns the food to break it down into small particles. It then pushes the small particles of food into the first part of the small intestine, called the duodenum. The small intestine is where most of the digestion and absorption of our food takes place.2.The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine and push the mixture forward to help with further digestion. The walls of the small intestine absorb the digested nutrients into the bloodstream. The blood delivers the nutrients to the rest of the body.3.The small intestine absorbs most of the nutrients in your food, and your circulatory system passes them on to other parts of your body to store or use. Special cells help absorbed nutrients cross the intestinal lining into your bloodstream.4.The small intestine absorbs most digested food molecules, as well as water and minerals, and passes them on to other parts of the body for storage or further chemical change. Specialized cells help absorbed materials cross the intestinal lining into the bloodstream.

Go around your house and hit (or tap) ten different objects. The objects should be different shapes and made of different material (choose things to hit that won’t break!). Each object is a different medium for sound. Try to hit each using the same amount of energy.
Describe each object that you hit and the sound it made.
Rank the ten objects from loudest to softest.
Make some conclusions based on your results from Steps 1 and 2. For example, are there a certain shapes or materials that are better or worse media for sound travel?
Stairs, wall, door, window, picture, floor, desk, backpack, paper, bed all of these produce different sound.
What is sound?Sound is defined as an acoustic wave is a vibration that travels through a gas, liquid, or solid transmission medium. In terms of human physiology and psychology, sound is the brain's receipt of these waves and perception of them. A mechanical disturbance that causes an equilibrium condition to be disturbed and propagates through an elastic material medium.
The vibration of items creates sound, which travels from one place to another through a medium. Vibration is the phrase used to describe an object's to-and-fro or back-and-forth motion. Vibrations are generated by objects in motion.
Thus, stairs, wall, door, window, picture, floor, desk, backpack, paper, bed all of these produce different sound.

Imaging playing a game of baseball on the moon, which has less gravity than Earth and no atmosphere. How would you want to change the game to make it play fairly and fun again?
A technique to change the game to make it play fairly and fun again is to deflate the ball in an attempt make it less bouncy.
Discussion:
A characteristic of the baseball game is that the baseball is less bouncy in comparison to other sports like football and basketball.
When the baseball game is played on the moon with a less gravity; the ball tends to ascend more as the force of gravity is lower compared to that of the earth.
Ultimately, lowering the air pressure in the baseball makes the ball less bouncy and the game may become fun to play again.
