Ques:Answer the following question given this paragraph: This diagram represents the cell cycle in eukaryotes. The cell cycle depicts the life of an eukaryotic cell. The cell cycle has four phases: the first growth or gap (G 1 ) phase, the synthesis (S) phase, the second growth or gap (G 2 ) phase and the mitotic (M) phase. The M phase includes mitosis and cytokinesis. The cell spends the majority of the cycle in the first three phases (G 1 , S, G 2 ) of the cycle, collectively known as interphase. After cytokinesis, two genetically identical daughter cells are formed. Q: How many cycles do cells have? Choices: - six - two - seven - four A:

Ans:four

Ques:Answer the following question given this paragraph: Excretion is the process of removing wastes and excess water from the body. It is one of the major ways the body maintains homeostasis. Q: What term is used to describe the process of removing wastes and excess water from the body? Choices: - diffusion - digestion - aeration - excretion A:

Ans:excretion

Ques:Answer the following question given this paragraph: As we saw in the previous chapter, ions are formed when atoms gain or lose electrons. If an atom loses one or more electrons, the resulting ion has a positive charge (more protons are present than electrons). If the atom gains one or more electrons, the resulting ion has a negative charge (more electrons are present than protons). Positive ions are called cations, and negative ions are called anions. Because opposite charges attract one another, cations and anions are held together by strong electromagnetic forces. An ionic compound consists of a large three-dimensional array of alternating cations and anions. For example, sodium chloride (NaCl) is composed of Na + and Cl - ions arranged into a structure like the one shown in Figure below . Q: When atoms gain or lose electrons, what is formed? Choices: - crystals - molecules - gas - ions A:

Ans:ions

The main way to keep your respiratory system healthy is to avoid smoking or breathing in the smoke of others. Q: Common disease of what system include asthma, pneumonia, and emphysema? Choices: - the fecal system - the digestive system - the glandular system - the respiratory system A:

Ans:
the respiratory system
