Answer the following question given this paragraph: Autoimmune diseases occur when the immune system fails to recognize the body's own molecules as "self," or belonging to the person. Instead, it attacks body cells as though they were dangerous pathogens. Some relatively common autoimmune diseases are listed in Table below . These diseases cannot be cured, although they can be treated to relieve symptoms and prevent some of the long-term damage they cause. Q: What kind of diseases involve the immune system accidentally attacking healthy body cells? Choices: - contagious diseases - metabolic - inflammation - autoimmune A:
autoimmune
Answer the following question given this paragraph: In the picture above, a thermal pack is applied to the back. Small packs can be used either for heating or cooling, depending on the material used. A heat pack contains a supersaturated solution of material such as sodium acetate. The solution is clear until a small metal trigger is activated. The sodium acetate then crystallizes out of solution and generates heat in the process. Q: Where can you find sodium acetate? Choices: - table salt - baking soda - a cold pack - a heat pack A:
a heat pack
Q: Answer the following question given this paragraph: Water droplets form when the air reaches 100% humidity. If the temperature is cold enough, frost will form. Q: Water droplets form when the air reaches 100-percent what? Choices: - density - chance of rain - heat - humidity A:
A: humidity
Question: Answer the following question given this paragraph: 9.5 | Types of Body Movements By the end of this section, you will be able to: Define the different types of body movements Identify the joints that allow for these motions Synovial joints allow the body a tremendous range of movements. Each movement at a synovial joint results from the contraction or relaxation of the muscles that are attached to the bones on either side of the articulation. The type of movement that can be produced at a synovial joint is determined by its structural type. While the ball-and-socket joint gives the greatest range of movement at an individual joint, in other regions of the body, several joints may work together to produce a particular movement. Overall, each type of synovial joint is necessary to provide the body with its great flexibility and mobility. There are many types of movement that can occur at synovial joints (Table 9.1). Movement types are generally paired, with one being the opposite of the other. Body movements are always described in relation to the anatomical position of the body: upright stance, with upper limbs to the side of body and palms facing forward. Refer to Figure 9.12 as you go through this section. Q: Synovial and ball-and-socket are both types of what? Choices: - bonds - cells - muscles - joints A:
Answer: joints

Answer the following question given this paragraph: Most invertebrates reproduce sexually. Diploid adults produce haploid gametes (sperm and eggs). In some species, the same individuals produce both sperm and eggs. In other species, sperm and eggs are produced by separate male and female individuals. Fertilization occurs when a sperm and an egg fuse to form a diploid zygote. The zygote develops into an embryo and eventually into a new adult organism. On the way, it may pass through one or more larval stages. A larva (plural, larvae) is a juvenile, or immature, stage of an animal. It is generally quite different in form and function from the adult form of the species. For example, the larva may be able to swim freely, whereas the adult must remain permanently attached to a solid surface. Q: How do invertebrates reproduce? Choices: - randomly - constantly - asexually - sexually A:
**Answer**
sexually

Answer the following question given this paragraph: Scientists collect evidence to test a hypothesis. The evidence may refute the hypothesis. In that case, it will be thrown out. The evidence may support the hypothesis. The scientists will then gather more evidence. The scientists will accept the hypothesis if: (1) There is no significant evidence to refute the hypothesis. (2) There is an enormous amount of evidence to support the hypothesis. The hypothesis may then become a theory. Q: What do scientists collect to test a hypothesis? Choices: - arguements - beilefs - books - evidence A:
(Answer)
evidence
