Explanation:
A plate breaking when falling to the floor would be a physical change, not chemical, as what the plate is created from would not change.
An icicle melting in the sun would be a physical change, as an icicle is frozen water, and after melting it would be normal water.
A can being crushed is still just a physical change, as the material making the can(typically aluminum) has not changed.
When a jet airplane starts its engines, fuel is combusted, creating energy for the engines to start. This would create the loud noise. As fuel is combusted, it turns into different things, henceforth the sound would imply a chemical change has occurred.

Rewrite the sentences:
1. all matter is made up of tiny particles calles atoms and molecules
2. right
3. right
4. compounds are chemically joined together
task 2:
1. i know this is element
2. i know this is compound
3. i know this is mixture
task 3:
In this lesson i have learned that Atoms are in everything and are what makes up most of the stuff on earth. They are tiny molecules that make up me and everything around me. I have also learned that atoms are made up of Elements. Elements are chemical molecules that make up things like the air we breathe. However, when more than one element joins together a compound is formed. Compounds make up more physical things around me such as drinking water and salt for cooking. When many different compounds are joined together a mixture is formed. An example of a mixture can be sand and water.
Explanation:
Along the inferior surface of the liver are several structures that collectively resemble the letter H. The gallbladder and the round ligament of the liver form the vertical superior parts of the H; the inferior vena cava and the <em>ligamentum </em><em>venosum</em> form the vertical inferior parts.
- The gallbladder is a pear-shaped organ localized on the right side of the body, directly under the liver. This organ functions to store a digestive fluid called bile until it's needed for digestion.
- The round ligament of the liver (also called <em>ligamentum teres hepatis</em>) is a remnant of the fetal umbilical vein. This ligament is part of the coronary ligament of the liver.
- The <em>ligamentum venosum</em> (also called the hepatogastric ligament) is a deep cleft on the posterior surface of the liver. It is a fetal remnant ligament attached to the left branch of the portal vein within the porta <em>hepatis</em>.
