Q: What is the largest mammal on earth? Read this paragraph and choose the correct option from the provided answers: Biological organization exists at all levels in organisms. It can be seen at the smallest level, in the molecules that make up such compounds as DNA and proteins, to the largest level, in an organism such as a blue whale, the largest mammal on Earth. Similarly, single celled prokaryotes and eukaryotes show order in the way their cells are arranged. Single-celled organisms such as an amoeba are free-floating and independent-living. Their single-celled "bodies" are able to carry out all the processes of life such as metabolism and respiration without help from other cells. Choices: - tiger shark - water buffalo - giraffe - blue whale A:
blue whale

Q: Strangeness, charm, bottomness, and topness are properties of what subatomic particle? Read this paragraph and choose the correct option from the provided answers: symbols are the values for antiquarks. B is baryon number, S is strangeness, c is charm, b is bottomness, t is topness. Values are approximate, are not directly observable, and vary with model. Choices: - pion - dark matter - molecules - quarks A:
quarks

Q: Q: What serious sti can damage the heart, brain and other organs or even cause death, if untreated? Read this paragraph and choose the correct option from the provided answers: Syphilis is a very serious STI. Luckily, it is less common than chlamydia or gonorrhea. Syphilis usually begins with a small sore on the genitals. This is followed a few months later by a rash and flu-like symptoms. If syphilis is not treated, it may damage the heart, brain, and other organs. It can even cause death. Choices: - herpes - chlamydia - cirrhosis - syphilis A:
A: syphilis

Question: Q: Ionic compound atoms of various elements gain or lose electrons to? Read this paragraph and choose the correct option from the provided answers: So far we have looked at ionic compounds, in which atoms of various elements gain or lose electrons to produce ions. The resulting ions are held together by strong attractions between oppositely charged particles. However, this only works for bonds between atoms in which one partner (the metal) has a tendency to lose electrons, and the other (the nonmetal) has a tendency to gain them. Then how might two nonmetals, such as nitrogen and oxygen, form chemical bonds? Neither is likely to lose electrons and become a cation, but both require more electrons to reach a noble gas configuration. Instead of a complete transfer of electrons, these atoms can bond by sharing electrons, producing what is called a covalent bond . When a group of atoms are joined together by covalent bonds, the resulting structure is called a molecule . Molecules are generally much smaller than the extended three-dimensional networks of ions that are seen in ionic compounds. We will look much more at covalent bonding and molecules in future chapters, but for now, we will focus on the ways in which molecules are named. Choices: - become ions - expel ions - flatten ions - produce ions A:
Answer: produce ions

Q: Unlike other tetrapod vertebrates (reptiles, birds, and mammals), amphibians do not produce what type of eggs? Read this paragraph and choose the correct option from the provided answers: Unlike other tetrapod vertebrates (reptiles, birds, and mammals), amphibians do not produce amniotic eggs. Therefore, they must lay their eggs in water so they won't dry out. Their eggs are usually covered in a jelly-like substance, like the frog eggs shown in Figure below . The jelly helps keep the eggs moist and offers some protection from predators. Choices: - epithelial - prokaryotic - umbilical - amniotic A:
**Answer**
amniotic

These gases include carbon dioxide, methane, water vapor, and ozone. Choices: - fluorine and nitrogen - methane and helium - ozone - greenhouse A:
(Answer)
greenhouse
