Answer the following question given this paragraph: Anaerobic exercises involve the muscles working against resistance. In this case the resistance is the weight of a barbell. Q: When performing anaerobic exercise, your muscles work against what? Choices: - gravity - momentum - inertia - resistance A:
resistance
Answer the following question given this paragraph: Mollusks live in most terrestrial, freshwater, and marine habitats. However, the majority of species live in the ocean. They can be found in both shallow and deep water and from tropical to polar latitudes. Mollusks are a major food source for other organisms, including humans. You may have eaten mollusks such as clams, oysters, scallops, or mussels. Q: Clams, oysters, scallops, and mussels are examples of what type of species? Choices: - mammals - invertebrates - tortoises - mollusks A:
mollusks
Q: Answer the following question given this paragraph: Horner's syndrome is a condition that presents with changes in one eye, such as pupillary constriction and dropping of eyelids, as well as decreased sweating in the face. Why could a tumor in the thoracic cavity have an effect on these autonomic functions? 32. The cardiovascular center is responsible for regulating the heart and blood vessels through homeostatic mechanisms. What tone does each component of the cardiovascular system have? What connections does the cardiovascular center invoke to keep these two systems in their resting tone? 33. Why does smoking increase the risk of heart disease? Provide two reasons based on autonomic function. Why might topical, cosmetic application of atropine or scopolamine from the belladonna plant not cause fatal poisoning, as would occur with ingestion of the plant?. Q: Which part of the body shows does horner's syndrome affect? Choices: - the nose - the tongue - the mouth - one eye A:
A: one eye
Question: Answer the following question given this paragraph: Stratum Corneum The stratum corneum is the most superficial layer of the epidermis and is the layer exposed to the outside environment (see Figure 5.5). The increased keratinization (also called cornification) of the cells in this layer gives it its name. There are usually 15 to 30 layers of cells in the stratum corneum. This dry, dead layer helps prevent the penetration of microbes and the dehydration of underlying tissues, and provides a mechanical protection against abrasion for the more delicate, underlying layers. Cells in this layer are shed periodically and are replaced by cells pushed up from the stratum granulosum (or stratum lucidum in the case of the palms and soles of feet). The entire layer is replaced during a period of about 4 weeks. Cosmetic procedures, such as microdermabrasion, help remove some of the dry, upper layer and aim to keep the skin looking "fresh" and healthy. Q: The dead, dry stratum corneum is the most superficial layer of what and is the layer exposed to the outside environment? Choices: - intestinal - lungs - dermis - epidermis A:
Answer: epidermis

Answer the following question given this paragraph: Convex lenses are thicker in the middle than at the edges. They cause rays of light to converge, or meet, at a point called the focus (F). Convex lenses form either real or virtual images. It depends on how close an object is to the lens relative to the focus. Figure below shows how a convex lens works. You can also interact with an animated convex lens at the URL below. An example of a convex lens is a hand lens. Q: Convex lenses are thicker in the middle than at the edges so they cause rays of light to converge, or meet, at a point called what? Choices: - the center - the base - the apex - focus A:
**Answer**
focus
Answer the following question given this paragraph: One of the simplest ways of detecting radioactivity is by using a piece of photographic film embedded in a badge or a pen. On a regular basis, the film is developed and checked for exposure. Comparing the exposure level of the film with a set of standard exposures indicates the amount of radiation a person was exposed to. Another means of detecting radioactivity is an electrical device called a Geiger counter (Figure 15.2 "Detecting Radioactivity"). It contains a gas-filled chamber with a thin membrane on one end that allows radiation emitted from radioactive nuclei to enter the chamber and knock electrons off atoms of gas (usually argon). The presence of electrons and positively charged ions causes a small current, which is detected by the Geiger counter and converted to a signal on a meter or, commonly, an audio circuit to produce an audible "click. Q: A geiger counter is used for detecting what? Choices: - mutation - pressure - convection - radiation A:
radiation
