Q: Answer the following question given this paragraph: Matter can be classified on the basis of its interactions with light. Matter may be transparent, translucent, or opaque. An example of each type of matter is pictured in the Figure below . Q: Transparent, translucent, or opaque are properties of matter based on an interaction with what? A:

OPTIONS:
- air
- electricity
- gravity
- light

A: light

input: OPTIONS:
- electrilizes it
- creates it
- heats it
- magnetizes it Now, answer this question: Answer the following question given this paragraph: As you can see in Figure above , a transformer consists of two wire coils wrapped around an iron core. When alternating primary current passes through coil P, it magnetizes the iron core. Because the current is alternating, the magnetic field of the iron core keeps reversing. This changing magnetic field induces alternating current in coil S, which is part of another circuit. In Figure above , coil P and coil S have the same number of turns of wire. In this case, the voltages of the primary and secondary currents are the same. However, when the two coils have different numbers of turns, the voltage of the secondary current is different than the voltage of the primary current. Both cases are illustrated in Figure below . Q: When alternating primary current passes through coil p, it does what to the iron core? A:
A:
output: magnetizes it

Answer the following question given this paragraph: Some extrusive igneous rocks cool so rapidly that crystals do not develop at all. These form a glass, such as obsidian. Others, such as pumice, contain holes where gas bubbles were trapped in the lava. The holes make pumice so light that it actually floats in water. The most common extrusive igneous rock is basalt. It is the rock that makes up the ocean floor. Shown below are three types of extrusive igneous rocks ( Figure below ). Q: What helps pumice float in water? A:

OPTIONS:
- high density
- large mass
- gravity
- gas bubble holes

Answer: gas bubble holes

Problem: OPTIONS:
- excessive
- nuclear
- kinetic
- potential
Q: Answer the following question given this paragraph: Q: The fact that water in a reservoir is elevated above the ground means that it has what kind of energy? A:
Answer: potential

Problem:OPTIONS:
- distillate
- condensation
- vapor
- ice

Answer the following question given this paragraph: The intermolecular structure of ice has spaces that are not present in liquid water. Q: The intermolecular structure of what has spaces that are not present in liquid water? A:
****
A: ice

Problem:OPTIONS:
- Mitosis
- internalization
- fermentation
- gastrulation

Answer the following question given this paragraph: Gastrulation The typical blastula is a ball of cells. The next stage in embryonic development is the formation of the body plan. The cells in the blastula rearrange themselves spatially to form three layers of cells. This process is called gastrulation. During gastrulation, the blastula folds upon itself to form the three layers of cells. Each of these layers is called a germ layer and each germ layer differentiates into different organ systems. The three germs layers, shown in Figure 43.26, are the endoderm, the ectoderm, and the mesoderm. The ectoderm gives rise to the nervous system and the epidermis. The mesoderm gives rise to the muscle cells and connective tissue in the body. The endoderm gives rise to columnar cells found in the digestive system and many internal organs. Q: What is the process of the blastula forming 3 layers of cells called? A:
****
A:
gastrulation
