Answer the following question given this paragraph: What do these two photos have in common? They both represent electromagnetic waves. These are waves that consist of vibrating electric and magnetic fields. They transmit energy through matter or across space. Some electromagnetic waves are generally harmless. The light we use to see is a good example. Other electromagnetic waves can be very harmful and care must be taken to avoid too much exposure to them. X rays are a familiar example. Why do electromagnetic waves vary in these ways? It depends on their properties. Like other waves, electromagnetic waves have properties of speed, wavelength, and frequency. Q: Vibrating electric and magnetic fields make up what kinds of waves? Choices: - seismic - eletrical - mechanical - electromagnetic A:
electromagnetic
Answer the following question given this paragraph: Which of the following is matter and not matter? 1. the moon 2. an idea for a new invention Answer 1. The moon is matter. The invention itself may be matter, but the idea for it is not. To understand matter and how it changes, we need to be able to describe matter. There are two basic ways to describe matter: physical properties and chemical properties. Physical properties are characteristics that describe matter as it exists. Some of many physical characteristics of matter are shape, color, size, and temperature. An important physical property. Q: Physical properties are characteristics that describe what as it exists? Choices: - imagination - antimatter - life - matter A:
matter
Q: Answer the following question given this paragraph: Sensorium Those parts of the brain involved in the reception and interpretation of sensory stimuli are referred to collectively as the sensorium. The cerebral cortex has several regions that are necessary for sensory perception. From the primary cortical areas of the somatosensory, visual, auditory, and gustatory senses to the association areas that process information in these modalities, the cerebral cortex is the seat of conscious sensory perception. In contrast, sensory information can also be processed by deeper brain regions, which we may vaguely describe as subconsciousfor instance, we are not constantly aware of the proprioceptive information that the cerebellum uses to maintain balance. Several of the subtests can reveal activity associated with these sensory modalities, such as being able to hear a question or see a picture. Two subtests assess specific functions of these cortical areas. The first is praxis, a practical exercise in which the patient performs a task completely on the basis of verbal description without any demonstration from the examiner. For example, the patient can be told to take their left hand and place it palm down on their left thigh, then flip it over so the palm is facing up, and then repeat this four times. The examiner describes the activity without any movements on their part to suggest how the movements are to be performed. The patient needs to understand the instructions, transform them into movements, and use sensory feedback, both visual and proprioceptive, to perform the movements correctly. Q: What term is used to describe the parts of the brain involved in the reception and interpretation of sensory stimuli collectively? Choices: - glial cells - neurons - medulla oblongata - sensorium A:
A: sensorium
Question: Answer the following question given this paragraph: Non-polar molecules can interact by way of London dispersion forces. Q: What type of force allows non-polar molecules to interact? Choices: - experienced dispersion - centrifigal dispersion - graviitational force - london dispersion A:
Answer: london dispersion

Answer the following question given this paragraph: Every plant and animal depends on its traits to survive. Survival may include getting food, building homes, and attracting mates. Traits that allow a plant, animal, or other organism to survive and reproduce in its environment are called adaptations . Q: What do you call the traits that allow a plant, animal, or other organism to survive and reproduce in its environment? Choices: - additions - advantages - settings - adaptations A:
**Answer**
adaptations
Q: Answer the following question given this paragraph: High-density materials are much more effective protection against gamma emissions than low-density ones. Gamma rays are usually blocked effectively by lead shielding. The thickness of the shielding will determine the effectiveness of the protection offered by the lead. Q: What element is typically used to shield things from gamma rays? Choices: - gold - silver - aluminum - lead A:
A: lead
