Answer the following question given this paragraph: Electron configuration notation eliminates the boxes and arrows of orbital filling diagrams. Each occupied sublevel designation is written followed by a superscript that is the number of electrons in that sublevel. For example, the hydrogen configuration is 1 s 1 , while the helium configuration is 1 s 2 . Multiple occupied sublevels are written one after another. The electron configuration of lithium is 1 s 2 2 s 1 . The sum of the superscripts in an electron configuration is equal to the number of electrons in that atom, which is in turn equal to its atomic number. Q: The sum of the superscripts in an electron configuration is equal to the number of electrons in that atom, which is in turn equal to what number? Choices: - metallic number - shell number - orbital number - atomic number A:
atomic number
Answer the following question given this paragraph: Q: What type of tissue runs the length of a stem in vascular bundles? Choices: - thermal tissue - muscle tissue - cardiac tissue - vascular tissue A:
vascular tissue
Q: Answer the following question given this paragraph: Much of the weather occurs at fronts, where air masses meet. Q: What occurs when air masses meet? Choices: - earthquakes - currents - tides - fronts A:
A: fronts
Question: Answer the following question given this paragraph: When a soluble compound dissolves, its constituent atoms, molecules, or ions disperse throughout the solvent. In contrast, the constituents of an insoluble compound remain associated with one another in the solid. A soluble compound is a strong electrolyte if it dissociates completely into ions, a weak electrolyte if it dissociates only slightly into ions, and a nonelectrolyte if it dissolves to produce only neutral molecules. Q: When a soluble compound dissolves, its constituent atoms, molecules, or ions disperse throughout what? Choices: - gel - pigment - liquid - solvent A:
Answer: solvent

Answer the following question given this paragraph: Scars and Keloids Most cuts or wounds, with the exception of ones that only scratch the surface (the epidermis), lead to scar formation. A scar is collagen-rich skin formed after the process of wound healing that differs from normal skin. Scarring occurs in cases in which there is repair of skin damage, but the skin fails to regenerate the original skin structure. Fibroblasts generate scar tissue in the form of collagen, and the bulk of repair is due to the basket-weave pattern generated by collagen fibers and does not result in regeneration of the typical cellular structure of skin. Instead, the tissue is fibrous in nature and does not allow for the regeneration of accessory structures, such as hair follicles, sweat glands, or sebaceous glands. Sometimes, there is an overproduction of scar tissue, because the process of collagen formation does not stop when the wound is healed; this results in the formation of a raised or hypertrophic scar called a keloid. In contrast, scars that result from acne and chickenpox have a sunken appearance and are called atrophic scars. Scarring of skin after wound healing is a natural process and does not need to be treated further. Application of mineral oil and lotions may reduce the formation of scar tissue. However, modern cosmetic procedures, such as dermabrasion, laser treatments, and filler injections have been invented as remedies for severe scarring. All of these procedures try to reorganize the structure of the epidermis and underlying collagen tissue to make it look more natural. Q: What is name for a piece of collagen-rich skin formed after the process of wound healing that differs from normal skin? Choices: - tissue - Sore - size - scar A:
**Answer**
scar
