Answer the following question given this paragraph: Molecular geometry is the three-dimensional arrangement of atoms in a molecule. The molecular geometry, or shape, of a molecule is an important factor that affects the physical and chemical properties of a compound. Those properties include melting and boiling points, solubility, density, and the types of chemical reactions that a compound undergoes. In this lesson, you will learn a technique to predict molecular geometry based on a molecule's Lewis electron dot structure. Q: Molecular geometry is the three-dimensional arrangement of atoms in a what? Choices: - genes - DNA - nucleus - molecule A:
molecule

Answer the following question given this paragraph: Current Situation : Currently the heating effect of extra greenhouse gases (since the start of the industrial revolution) is equal to about . Thus the recent period has recorded parallel increases in concentration of carbon dioxide and average global temperature. As more greenhouse gases are put into the atmosphere the temperature will increase further. There are certain effects of a warmer Earth (discussed more in optional section), which could accelerate the process, even if no more greenhouse gases are put into the atmosphere (an unlikely prospect for the foreseeable future). Q: Earth's temperature will increase further as more of what colorfully nicknamed gases are put into the atmosphere? Choices: - bluehouse gases - blue dioxide gases - green dioxide gases - greenhouse gases A:
(Answer)
greenhouse gases
Ques: Answer the following question given this paragraph: 25.10 The Urinary System and Homeostasis The effects of failure of parts of the urinary system may range from inconvenient (incontinence) to fatal (loss of filtration and many others). The kidneys catalyze the final reaction in the synthesis of active vitamin D that in turn helps regulate Ca++. The kidney hormone EPO stimulates erythrocyte development and promotes adequate O2 transport. The kidneys help regulate blood pressure through Na+ and water retention and loss. The kidneys work with the adrenal cortex, lungs, and liver in the reninangiotensinaldosterone system to regulate blood pressure. They regulate osmolarity of the blood by regulating both solutes and water. Three electrolytes are more closely regulated than others: Na+, Ca++, and K+. The kidneys share pH regulation with the lungs and plasma buffers, so that proteins can preserve their three-dimensional conformation and thus their function. Q: What paired organs help regulate blood pressure through sodium ion and water retention and loss? Choices: - lungs - tissues - lymph nodes - kidneys A:
Ans: kidneys

Answer the following question given this paragraph: According to the kinetic theory, particles of matter are in constant motion. The energy of motion is called kinetic energy. Q: What is the energy of motion called? Choices: - inertia - harmonic energy - stasis - kinetic energy A:
(A).
kinetic energy
Ques:Answer the following question given this paragraph: Scientific method is a process consisting of making observations, developing a hypothesis, and testing that hypothesis. Q: What takes place directly after developing a hypothesis in the scientific method process? Choices: - gathering materials - making a conclusion - independent variables - testing the hypothesis A:

Ans:testing the hypothesis
Question: Answer the following question given this paragraph: Color is probably the easiest property to observe. Unfortunately, you can rarely identify a mineral only by its color. Sometimes, different minerals are the same color. For example, you might find a mineral that is a golden color and think it is gold. But it might actually be pyrite, or "fool's gold," which is made of iron and sulfide. It contains no gold atoms. Q: Although it is the easiest to observe, what property is not ideal as a sole way to identify minerals? Choices: - temperature - density - composition - color A:
Answer:
color
