Answer the following question given this paragraph: Discussions of colors can sometimes become confusing because of the difference between light emitters and light absorbers. Light absorbers, such as dyes and pigments, absorb frequencies from those that you see, while light emitters add frequencies to what you see. If I were to shine red light, green light, and blue light into your eye all at the same time, you would likely see some variation of white. If I were to mix red paint, green paint, and blue paint together, you would likely see black or some very dark color. Q: What do light emitters do to what you see? A:
OPTIONS:
- divide frequencies
- subtract frequencies
- block frequencies
- add frequencies
add frequencies

Answer the following question given this paragraph: As plant cells grow, they also become specialized into different cell types. Once cells become specialized, they can no longer divide. So how do plants grow after that? The key to continued growth is meristem. Meristem is a type of plant tissue consisting of undifferentiated cells that can continue to divide. Q: Once a plant cell becomes specialized, what can they no longer do? A:
OPTIONS:
- photosynthesis
- cellular respiration
- osmosis
- divide

Answer: divide

Question: Answer the following question given this paragraph: Humans and apes have five fingers they can use to grasp objects. Do you think these are analogous or homologous structures? Explain. Q: How many fingers do apes have on each hand? A:
OPTIONS:
- seven
- six
- four
- five
Answer: five

input with options: Answer the following question given this paragraph: Mercury(II) oxide is a red solid. When it is heated to a temperature above 500C, it easily decomposes into mercury and oxygen gas. The red color of the mercury oxide reactant becomes the silver color of mercury. The color change is the sign that the reaction is occurring. Q: What is the color of mercury(ii) oxide? A:
OPTIONS:
- copper
- blue
- green
- red
output: red

Q: Answer the following question given this paragraph: Active transport requires energy from the cell. It occurs when substances move from areas of lower to higher concentration or when very large molecules are transported. Types of active transport include ion pumps, such as the sodium-potassium pump, and vesicle transport, which includes endocytosis and exocytosis. Q: What occurs when substances move from areas of lower to higher concentration or when very large molecules are transported? A:

OPTIONS:
- migration
- diffusion
- passive transport
- active transport

A: active transport

Answer the following question given this paragraph: Overcoming Density-Dependent Regulation Humans are unique in their ability to alter their environment with the conscious purpose of increasing its carrying capacity. This ability is a major factor responsible for human population growth and a way of overcoming density-dependent growth regulation. Much of this ability is related to human intelligence, society, and communication. Humans can construct shelter to protect them from the elements and have developed agriculture and domesticated animals to increase their food supplies. In addition, humans use language to communicate this technology to new generations, allowing them to improve upon previous accomplishments. Other factors in human population growth are migration and public health. Humans originated in Africa, but have since migrated to nearly all inhabitable land on the Earth. Public health, sanitation, and the use of antibiotics and vaccines have decreased the ability of infectious disease to limit human population growth. In the past, diseases such as the bubonic plaque of the fourteenth century killed between 30 and 60 percent of Europe's population and reduced the overall world population by as many as 100 million people. Today, the threat of infectious disease, while not gone, is certainly less severe. According to the World Health Organization, global death from infectious disease declined from 16.4 million in 1993 to 14.7 million in 1992. To compare to some of the epidemics of the past, the percentage of the world's population killed between 1993 and 2002 decreased from 0.30 percent of the world's population to 0.24 percent. Thus, it appears that the influence of infectious disease on human population growth is becoming less significant. Q: Humans are unique in their ability to alter their environment with the conscious purpose of increasing what, which acts as a limiting factor on populations in general? A:
OPTIONS:
- density dependent limitation
- containing capacity
- niche
- carrying capacity
carrying capacity
