Ques: Answer the following question given this paragraph: New species arise in the process of speciation. Allopatric speciation occurs when some members of a species become geographically separated. They then evolve genetic differences. If the differences prevent them from interbreeding with the original species, a new species has evolved. Sympatric speciation occurs without geographic separation. Q: What occurs when some members of a species become geographically separated? Choices: - divergent speciation - symbiotic speciation - reflective speciation - allopatric speciation A:
Ans: allopatric speciation

Ques: 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:
Ans: atoms

Ques: Answer the following question given this paragraph: Pluto was different in other ways. The outer planets are all gas giants. Pluto is small, icy, and rocky. Pluto has a diameter of about 2,400 km. It has only about one-fifth the mass of Earth's Moon. Pluto's orbit is tilted relative to the other planets. It's orbit is shaped like a long, narrow ellipse. Pluto's orbit sometimes even passes inside Neptune's orbit. Q: What, now former, planet is small, icy, and rocky? Choices: - mercury - jupiter - neptune - pluto A:
Ans: pluto

Ques: Answer the following question given this paragraph: Life science may be basic or applied science. The aim of basic science is to gain new knowledge and a better understanding of the natural world. The aim of applied science is to find solutions to practical problems. Q: What do you call a science that aims to find solutions to practical problems? Choices: - applied experience - experimental science - evolved science - applied science A:
Ans:
applied science
