Answer the following question given this paragraph: How metalloids behave in chemical interactions with other elements depends mainly on the number of electrons in the outer energy level of their atoms. Metalloids may act either like metals or nonmetals in chemical reactions. Q: In chemical reactions, what substances can act like metals or nonmetals, depending on their number of electrons? Choices: - diacritics - minerals - synthetics - metalloids A:
metalloids
Answer the following question given this paragraph: Ethers are good solvents for other organic compounds because of their low reactivity. They readily dissolve non-polar molecules. Diethyl ether is perhaps the best known ether. It is widely used as a solvent and has been used as an inhalable anesthetic. Q: Ethers readily dissolve what type of molecules? Choices: - proteins - lipids - polar - non-polar A:
non-polar

A: temperature
Question: Answer the following question given this paragraph: A chloroplast consists of thylakoid membranes surrounded by stroma. The thylakoid membranes contain molecules of the green pigment chlorophyll. Q: What consists of thylakoid membranes surrounded by stroma? Choices: - a photon - a nucleus - a stem - a chloroplast A:
Answer: a chloroplast

Answer the following question given this paragraph: Amines generally have rather pungent or noxious odors. Ammonia can be considered the simplest amine and has a very distinctive odor. Methylamine has an unpleasant odor associated with dead fish. Amines are often formed biologically during the breakdown of proteins in animal cells, and so many have the smell of death and decay. Putrescine and cadaverine are two such amines and are aptly named for their foul odors. The toxins which many animals use as a form of defense are frequently amines. Amines are used industrially as dyes and in many drugs. Q: What are often formed biologically during the breakdown of proteins in animal cells, having the smell of death and decay?. Choices: - ketones - acids - enzymes - amines A:
**Answer**
amines
(Q).
Answer the following question given this paragraph: Maturation of the ovum. Notice only 1 mature ovum, or egg, forms during meiosis from the primary oocyte. Three polar bodies may form during oogenesis. These polar bodies will not form mature gametes. Conversely, four haploid spermatids form during meiosis from the primary spermatocyte. Q: Four haploid spermatids form during meiosis from what? Choices: - the zygote - the sister chromatic - the ova - the primary spermatocyte A:
(A).
the primary spermatocyte
