Answer the following question given this paragraph: Biochemical compounds make up the cells and tissues of organisms. They are also involved in life processes, such as making and using food for energy. Given their diversity of functions, it's not surprising that there are millions of different biochemical compounds. However, they can be grouped into just four main classes: carbohydrates, proteins, lipids, and nucleic acids. The classes are summarized in Table below and described in the rest of this lesson. Q: What type of compounds make up the cells and tissues of organisms? A:
OPTIONS:
- hormonal compounds
- productive compounds
- organic compounds
- biochemical compounds

Answer: biochemical compounds

Question: Answer the following question given this paragraph: We see an opaque object, such as the apple in Figure below , because it reflects some wavelengths of visible light. The wavelengths that are reflected determine the color that the object appears. For example, the apple in the figure appears red because it reflects red light and absorbs light of other wavelengths. We see a transparent or translucent object, such as the bottle in Figure below , because it transmits light. The wavelength of the transmitted light determines the color that the object appears. For example, the bottle in the figure appears blue because it transmits blue light. Q: The color of an object is determined by the what of it's reflected light? A:
OPTIONS:
- luminosity
- variation
- absorption
- wavelength
Answer: wavelength

input with options: Answer the following question given this paragraph: Did you ever see a meteor shower, like the one in Figure below ? Meteors burn as they fall through the mesosphere. The space rocks experience friction with the gas molecules. The friction makes the meteors get very hot. Many meteors burn up completely in the mesosphere. Q: What happens to meteors as they fall through the mesosphere? A:
OPTIONS:
- they grow
- they bounce
- they stop suddenly
- they burn
output: they burn

Q: Answer the following question given this paragraph: The Linnaean system of classification consists of a hierarchy of groupings, called taxa (singular, taxon). Taxa range from the kingdom to the species (see Figure below ). The kingdom is the largest and most inclusive grouping. It consists of organisms that share just a few basic similarities. Examples are the plant and animal kingdoms. The species is the smallest and most exclusive grouping. It consists of organisms that are similar enough to produce fertile offspring together. Closely related species are grouped together in a genus. Q: What do we call the system of classification consisting of a hierarchy of groupings called taxa? A:

OPTIONS:
- lamarckian system
- linchpin system
- crocodilian system
- linnaean system

A: linnaean system

input: OPTIONS:
- convection
- activation
- radiation
- conduction Now, answer this question: Answer the following question given this paragraph: Conduction is the transfer of thermal energy between particles of matter that are touching. Thermal conductors are materials that are good conductors of thermal energy. Thermal insulators are materials that are poor conductors of thermal energy. Both conductors and insulators have important uses. Q: What is the transfer of thermal energy between particles of matter that are touching called? A:
A:
output: conduction

Question: Answer the following question given this paragraph: 42.3 | Antibodies By the end of this section, you will be able to: Explain cross-reactivity Describe the structure and function of antibodies Discuss antibody production An antibody, also known as an immunoglobulin (Ig), is a protein that is produced by plasma cells after stimulation by an antigen. Antibodies are the functional basis of humoral immunity. Antibodies occur in the blood, in gastric and mucus secretions, and in breast milk. Antibodies in these bodily fluids can bind pathogens and mark them for destruction by phagocytes before they can infect cells. Q: What protein is produced when a plasma cell is stimulated by antigens? A:
OPTIONS:
- collagen
- dystrophin
- keratin
- immunoglobulin
Answer:
immunoglobulin
