Answer the following question given this paragraph: 2. Sedimentary rocks form when sediments are compacted and cemented together ( Figure below ). These sediments may be gravel, sand, silt or clay. Sedimentary rocks often have pieces of other rocks in them. Some sedimentary rocks form the solid minerals left behind after a liquid evaporates. Q: What kind of rock forms when material such as gravel, sand, silt or clay is compacted and cemented together? Choices: - ingenious - limestone - craters - sedimentary A:
sedimentary

Answer the following question given this paragraph: Absorptive protists absorb food molecules across their cell membranes. This occurs by diffusion. These protists are important decomposers. Q: Which process helps absorptive protists absorb food molecules across their cell membranes? Choices: - activation - secretion - metabolism - diffusion A:
(Answer)
diffusion

(Q).
Answer the following question given this paragraph: The density of matter can be calculated by dividing its mass by its volume. Q: How can you calculate the density of matter? Choices: - by subtracting mass from volume - by multiplying its mass by its volume - by dividing its volume by its mass - by dividing its mass by its volume A:
(A).
by dividing its mass by its volume
Ques:Answer the following question given this paragraph: Some behaviors seem to be controlled solely by genes. Others appear to be due to experiences in a given environment. Whether behaviors are controlled mainly by genes or by the environment is often a matter of debate. This is called the nature-nurture debate . Nature refers to the genes an animal inherits. Nurture refers to the environment that the animal experiences. Q: What two words describe the debate over whether behaviors are caused by genetics or by environment? Choices: - kinetic and potential - positive and negative - dominant and recessive - nature and nurture A:

Ans:nature and nurture
Answer the following question given this paragraph: The Formation of Ionic Compounds Binary ionic compounds are composed of just two elements: a metal (which forms the cations) and a nonmetal (which forms the anions). For example, NaCl is a binary ionic compound. We can think about the formation of such compounds in terms of the periodic properties of the elements. Many metallic elements have relatively low ionization potentials and lose electrons easily. These elements lie to the left in a period or near the bottom of a group on the periodic table. Nonmetal atoms have relatively high electron affinities and thus readily gain electrons lost by metal atoms, thereby filling their valence shells. Nonmetallic elements are found in the upper-right corner of the periodic table. Q: Compounds with metals and nonmetals sharing electrons are known as what kinds of compounds? Choices: - acids - atoms - eons - ions A:
ions
