Q: Answer the following question given this paragraph: Did you notice that none of these statements relates to the identity of the gas? This means that all gases should behave similarly. A gas that follows these statements perfectly is called an ideal gas. Most gases show slight deviations from these statements and are called real gases. However, the existence of real gases does not diminish the importance of the kinetic theory of gases. One of the statements of the kinetic theory mentions collisions. As gas particles are constantly moving, they are also constantly colliding with each other and with the walls of their container. There are forces involved as gas particles bounce off the container walls (Figure 8.9 "Gas Pressure"). The force generated by gas particles divided by the. Q: Gases can be classifed as real or what? A:

OPTIONS:
- noble
- shape
- dense
- ideal

A: ideal

input: OPTIONS:
- thermal
- light
- intrinsic
- electrical Now, answer this question: Answer the following question given this paragraph: Sources of voltage include electric generators and cells. Electric generators change kinetic energy to electrical energy. Chemical cells change chemical energy to electrical energy, and solar cells change solar energy to electrical energy. Q: Electric generators change kinetic energy to what type of energy? A:
A:
output: electrical

Answer the following question given this paragraph: Australopithecus afarensis is a human ancestor that lived about 3 million years ago. Q: Australopithecus afarensis is an ancestor of what primate? A:

OPTIONS:
- lemurs
- orangutans
- gorillas
- humans

Answer: humans

Problem: OPTIONS:
- uterus
- spinal cord
- vas deferens
- placenta
Q: Answer the following question given this paragraph: The majority of mammals are placental mammals. These are mammals in which the developing baby is fed through the mother's placenta. Female placental mammals develop a placenta after fertilization. A placenta is a spongy structure that passes oxygen, nutrients, and other useful substances from the mother to the fetus. It also passes carbon dioxide and other wastes from the fetus to the mother. The placenta allows the fetus to grow for a long time within the mother. Q: What structure passes oxygen and nutrients to a growing fetus in mammals? A:
Answer: placenta

Problem:OPTIONS:
- hormonal, repressive, activator,
- repressive, activator, spontaneous
- transparent , activator , inducible
- repressive, activator, inducible

Answer the following question given this paragraph: 16.2 Prokaryotic Gene Regulation The regulation of gene expression in prokaryotic cells occurs at the transcriptional level. There are three ways to control the transcription of an operon: repressive control, activator control, and inducible control. Repressive control, typified by the trp operon, uses proteins bound to the operator sequence to physically prevent the binding of RNA polymerase and the activation of transcription. Therefore, if tryptophan is not needed, the repressor is bound to the operator and transcription remains off. Activator control, typified by the action of CAP, increases the binding ability of RNA polymerase to the promoter when CAP is bound. In this case, low levels of glucose result in the binding of cAMP to CAP. CAP then binds the promoter, which allows RNA polymerase to bind to the promoter better. In the last examplethe lac operontwo conditions must be met to initiate transcription. Glucose must not be present, and lactose must be available for the lac operon to be transcribed. If glucose is absent, CAP binds to the operator. If lactose is present, the repressor protein does not bind to its operator. Only when both conditions are met will RNA polymerase bind to the promoter to induce transcription. Q: What are the three ways to control the transcription of an operon? A:
****
A: repressive, activator, inducible

Problem:OPTIONS:
- divide frequencies
- subtract frequencies
- block frequencies
- add frequencies

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:
****
A:
add frequencies
