Q: Q: What term means the force of attraction that holds together oppositely charged ions? Read this paragraph and choose the correct option from the provided answers: An ionic bond is the force of attraction that holds together oppositely charged ions. Ionic bonds form crystals instead of molecules. Table salt contains ionic bonds. Choices: - electron bond - magnetic bond - solvent bond - ionic bond A:
A: ionic bond

Q: Q: What is a cluster of neuron cell bodies in the pns called? Read this paragraph and choose the correct option from the provided answers: Regardless of the appearance of stained or unstained tissue, the cell bodies of neurons or axons can be located in discrete anatomical structures that need to be named. Those names are specific to whether the structure is central or peripheral. A localized collection of neuron cell bodies in the CNS is referred to as a nucleus. In the PNS, a cluster of neuron cell bodies is referred to as a ganglion. Figure 12.4 indicates how the term nucleus has a few different meanings within anatomy and physiology. It is the center of an atom, where protons and neutrons are found; it is the center of a cell, where the DNA is found; and it is a center of some function in the CNS. There is also a potentially confusing use of the word ganglion (plural = ganglia) that has a historical explanation. In the central nervous system, there is a group of nuclei that are connected together and were once called the basal ganglia before "ganglion" became accepted as a description for a peripheral structure. Some sources refer to this group of nuclei as the "basal nuclei" to avoid confusion. Choices: - groupilion - gangnem - crystals - ganglion A:
A: ganglion

Q: Q: What system is designed to facilitate the transformation of food matter into the nutrient components that sustain organisms? Read this paragraph and choose the correct option from the provided answers: Parts of the Digestive System The vertebrate digestive system is designed to facilitate the transformation of food matter into the nutrient components that sustain organisms. Oral Cavity The oral cavity, or mouth, is the point of entry of food into the digestive system, illustrated in Figure 34.9. The food consumed is broken into smaller particles by mastication, the chewing action of the teeth. All mammals have teeth and can chew their food. The extensive chemical process of digestion begins in the mouth. As food is being chewed, saliva, produced by the salivary glands, mixes with the food. Saliva is a watery substance produced in the mouths of many animals. There are three major glands that secrete salivathe parotid, the submandibular, and the sublingual. Saliva contains mucus that moistens food and buffers the pH of the food. Saliva also contains immunoglobulins and lysozymes, which have antibacterial action to reduce tooth decay by inhibiting growth of some bacteria. Saliva also contains an enzyme called salivary amylase that begins the. Choices: - tissue - skeletal - respiratory - digestive A:
A: digestive

Q: Q: Lacking blood vessels, nerve endings, or glands, the epidermis is the outer layer of what? Read this paragraph and choose the correct option from the provided answers: The epidermis is the outer layer of skin. It consists almost entirely of epithelial cells. There are no blood vessels, nerve endings, or glands in this skin layer. Nonetheless, this layer of skin is very active. It is constantly being renewed. How does this happen?. Choices: - liver - brain - lungs - skin A:
A: skin
