Answer the following question given this paragraph: All matter is made of tiny particles. Protons, neutrons, and electrons form atoms that bond together to create molecules. Atoms are the smallest units that have the properties of an element. Molecules are the smallest units of a compound. Chemical bonds hold molecules together. Molecules form the different types of minerals. The silicates make up most of Earth's crust. Minerals come together to create the three major rock types. They are igneous, sedimentary, and metamorphic. Igneous rocks form from cooled magma. Sedimentary rocks form from compacted or cemented sediments. Metamorphic rocks are those that have been altered by heat and pressure. These three rock types are the material part of the rock cycle. They are connected by different processes. Different processes convert any type of rock into any other type of rock. These processes are weathering and erosion, crystallization, and burial and pressure, among others. Each rock contains a story of how it formed. For most rocks it is possible to know what it formed from. Q: The smallest units of matter that retain the unique properties of an element are known as what? Choices: - protons - molecules - neutrons - atoms A:
atoms

(Answer)
kilogram (kg)
Ques: Answer the following question given this paragraph: Living species of chordates are classified into three major subphyla: Vertebrata, Urochordata, and Cephalochordata. Vertebrates are all chordates that have a backbone. The other two subphyla are invertebrate chordates that lack a backbone. Members of the subphylum Urochordata are tunicates (also called sea squirts). Members of the subphylum Cephalochordata are lancelets . Both tunicates and lancelets are small and primitive. They are probably similar to the earliest chordates that evolved more than 500 million years ago. Q: Vertebrates are all chordates that have a what? Choices: - circulatory system - fossil - brain - backbone A:
Ans: backbone
(Q).
Answer the following question given this paragraph: The other end of each phospholipid molecule is nonpolar and has no electric charge. This end of the phospholipid molecule repels polar water and is described as hydrophobic, or "water hating. ". Q: What word describes a molecule that repels polar water? Choices: - monophobic - hydrophonic - soluble - hydrophobic A:
(A).
hydrophobic
Ques:Answer the following question given this paragraph: Q: In most animals, what sense is related to balance or equilibrium? Choices: - vision - tasting - feeling - hearing A:

Ans:hearing
Answer the following question given this paragraph: There are two major types of seismic waves. Body waves travel through the Earth's interior. Surface waves travel along the ground surface. In an earthquake, body waves are responsible for sharp jolts. Surface waves are responsible for rolling motions that do most of the damage in an earthquake. Q: Body waves and surface waves are the two major types of what, which occur during earthquakes? Choices: - tidal waves - current waves - sound waves - seismic waves A:
seismic waves
