Answer the following question given this paragraph: Our lives are filled with light. Through vision, the most valued of our senses, light can evoke spiritual emotions, such as when we view a magnificent sunset or glimpse a rainbow breaking through the clouds. Light can also simply amuse us in a theater, or warn us to stop at an intersection. It has innumerable uses beyond vision. Light can carry telephone signals through glass fibers or cook a meal in a solar oven. Life itself could not exist without light's energy. From photosynthesis in plants to the sun warming a cold-blooded animal, its supply of energy is vital. Q: Life itself could not exist without what energy, which plays a vital role in photosynthesis? A:
OPTIONS:
- time energy
- spin energy
- magnetic energy
- light energy
light energy

Answer the following question given this paragraph: Q: Karyotyping shows whether what structures, which contain genetic information, are normal in number and appearance? A:
OPTIONS:
- neutrons
- ribosomes
- nucleoids
- chromosomes

Answer: chromosomes

Question: Answer the following question given this paragraph: Over 90% of the energy we use comes originally from the sun. Every day, the sun provides the earth with almost 10,000 times the amount of energy necessary to meet all of the world's energy needs for that day. Our challenge is to find ways to convert and store incoming solar energy so that it can be used in reactions or chemical processes that are both convenient and nonpolluting. Plants and many bacteria capture solar energy through photosynthesis. We release the energy stored in plants when we burn wood or plant products such as ethanol. We also use this energy to fuel our bodies by eating food that comes directly from plants or from animals that got their energy by eating plants. Burning coal and petroleum also releases stored solar energy: These fuels are fossilized plant and animal matter. This chapter will introduce the basic ideas of an important area of science concerned with the amount of heat absorbed or released during chemical and physical changesan area called thermochemistry. The concepts introduced in this chapter are widely used in almost all scientific and technical fields. Food scientists use them to determine the energy content of foods. Biologists study the energetics of living organisms, such as the metabolic combustion of sugar into carbon dioxide and water. The oil, gas, and transportation industries, renewable energy providers, and many others endeavor to find better methods to produce energy for our commercial and personal needs. Engineers strive to improve energy efficiency, find better ways to heat and cool our homes, refrigerate our food and drinks, and meet the energy and cooling needs of computers and electronics, among other applications. Understanding thermochemical. Q: Over 90% of the energy we use comes originally from what? A:
OPTIONS:
- earth
- water
- horizon
- sun
Answer: sun

input with options: Answer the following question given this paragraph: An element is the simplest form of matter that has a unique set of properties. Examples of well-known elements include oxygen, iron, and gold (see the figure below). Elements cannot be broken down into a simpler substance. Likewise, one element cannot be chemically converted into a different element. Q: What is the term for the simplest form of matter that has a unique set of properties? A:
OPTIONS:
- an electron
- an atom
- a neutron
- an element
output: an element

Q: Answer the following question given this paragraph: Lipids are nutrients, such as fats that store energy. Lipids also have several other roles in the body. For example, lipids protect nerves and make up the membranes that surround cells. Q: What are lipids' function in relation to nerves? A:

OPTIONS:
- transportation
- reproduction
- conservation
- protection

A: protection

Answer the following question given this paragraph: Cartilage: There are three cartilage types: 1. hyaline cartilage 2. fibrocartilage (fibrous cartilage) 3. elastic cartilage Hyaline cartilage: most widespread cartilage type, in adults forms articular surfaces of long bones, rib tips, rings of trachea, and parts of skull. Mostly collagen, name refers to glassy appearance. In embryo, bones form first as hyaline cartilage, later ossifies. Found in tracheal rings. Few collagen fibers. Fibrous cartilage: have lots of collagen fibers. Found in intervertebral discs, pubic symphesis. Grades into dense tendon and ligament tissue. Elastic cartilage: springy and elastic. Found in internal support of external ear and in epiglottis, yellow when fresh. Chondrocites (cartilage cells) rely on diffusion for nutrients, as cartilage has no direct blood supply, and no enervation (nerves). Can be loaded with calcium salts. Q: Comprised mainly of collagen and associated with long bones and the skull, hyaline is the most widespread type of what? A:
OPTIONS:
- enzymes
- tissue
- cytoplasm
- collagen
collagen
