input: OPTIONS:
- cardiovascular
- reproductive system
- nervous system
- immune system Now, answer this question: Answer the following question given this paragraph: Most allergies can be treated with medicines. Medicines used to treat allergies include antihistamines and corticosteroids. These medicines help control the immune system when it attacks an allergen. Sometimes, allergies cause severe symptoms, a condition known as anaphylaxis. For example, they may cause the throat to swell so it is hard to breathe. Severe allergies may be life threatening. They require emergency medical care. Q: Prescribed to treat allergies, antihistamines and corticosteroids help control what system that attacks allergens? A:
A:
output: immune system

Answer the following question given this paragraph: An electric motor is a device that uses an electromagnet to change electrical energy to kinetic energy. When current flows through the motor, the electromagnet rotates, causing a shaft to rotate as well. The rotating shaft moves other parts of the device. Q: What device uses an electromagnet to change electrical energy to kinetic energy? A:

OPTIONS:
- public motor
- melodic motor
- Magnetic motor.
- electric motor

Answer: electric motor

Q: Answer the following question given this paragraph: Solids have a fixed volume and a fixed shape. Liquids have a fixed volume but take the shape of their container. Gases take both the volume and the shape of their container. Q: What takes both the shape and the volume of their container? A:
Answer: gases

Problem:OPTIONS:
- condensation
- saturation

- dispersion

Answer the following question given this paragraph: 25.5 Dispersion: The Rainbow and Prisms The spreading of white light into its full spectrum of wavelengths is called dispersion. Rainbows are produced by a combination of refraction and reflection and involve the dispersion of sunlight into a continuous distribution of colors. Dispersion produces beautiful rainbows but also causes problems in certain optical systems. Q: What is the spreading of white light into its full spectrum of wavelengths called? A:
****
A: dispersion

Answer the following question given this paragraph: The cell starting meiosis is called a primary oocyte, as shown in Figure 43.13. This cell will start the first meiotic division and be arrested in its progress in the first prophase stage. At the time of birth, all future eggs are in the prophase stage. At adolescence, anterior pituitary hormones cause the development of a number of follicles in an ovary. This results in the primary oocyte finishing the first meiotic division. The cell divides unequally, with most of the cellular material and organelles going to one cell, called a secondary oocyte, and only one set of chromosomes and a small amount of cytoplasm. Q: The cell starting meiosis is called a what? A:
OPTIONS:
- secondary oocyte
- primary gamete
- zygote
- primary oocyte
primary oocyte

Answer the following question given this paragraph: The trp Operon: A Repressor Operon Bacteria such as E. coli need amino acids to survive. Tryptophan is one such amino acid that E. coli can ingest from the environment. coli can also synthesize tryptophan using enzymes that are encoded by five genes. These five genes are next to each other in what is called the tryptophan (trp) operon (Figure 16.3). If tryptophan is present in the environment, then E. coli does not need to synthesize it and the switch controlling the activation of the genes in the trp operon is switched off. However, when tryptophan availability is low, the switch controlling the operon is turned on, transcription is initiated, the genes are expressed, and tryptophan is synthesized. Q: E. coli need what kind of acids to survive? A:
OPTIONS:
- hydrochloric
- bacterial
- boric
- amino

Answer:
amino
