Answer the following question given this paragraph: We can see two general types of effects when humans are exposed to radiation. Low-level exposure can lead to development of cancer. The regulatory processes regulating cell growth are disrupted, leading to uncontrolled growth of abnormal cells. Acute exposure can produce nausea, weakness, skin burns, and internal tissue damage. Cancer patients receiving radiation therapy experience these symptoms, but the radiation is targeted to a specific site in the body so that the damage is primarily to the cancer cells and the patient is able to recover from the exposure. Q: Low-level exposure of humans to radiation can cause what? Choices: - illness - coughing - bleeding - cancer A:
cancer
Q: Answer the following question given this paragraph: The only light that people can see is called visible light . This light consists of a very narrow range of wavelengths that falls between infrared light and ultraviolet light. Within the visible range, we see light of different wavelengths as different colors of light, from red light, which has the longest wavelength, to violet light, which has the shortest wavelength (see Figure below ). When all of the wavelengths of visible light are combined, as they are in sunlight, visible light appears white. You can learn more about visible light at this URL: http://www. youtube. com/watch?v=PMtC34pzKGc . Q: What do we call the only light that people can see? Choices: - wave light - spectral light - natural light - visible light A:
A: visible light

Answer the following question given this paragraph: Protists and Fungi are two types of eukaryotic organisms. What do they have in common? Protists are the earliest eukaryotes, and this kingdom contains some of the simplest eukaryotes. Many are single-celled organisms. Protists consist of animal-like, plant-like, and fungus-like species. Protists evolved into the other three types of eukaryotes, including fungi. Other than that, these two types of eukaryotes are very different. Fungi are eukaryotic organisms that cannot make their own food and do not "eat. " They must absorb their nutrients, usually from decaying organisms. Q: What eukaryotic organisms cannot make their own food and do not technically eat? Choices: - cells - plankton - proteins - fungi A:
**Answer**
fungi
