Answer the following question given this paragraph: This odd-looking creature is a fish called a puffer fish. Like all fish, puffer fish are vertebrates. The puffer fish puffs up by rapidly filling its stretchy stomach with water. The reason? Getting bigger makes the fish seem larger to potential predators. Just to be on the safe side, the puffer fish also produces venom. In fact, it's the second-most-poisonous vertebrate in the world after the poison dart frog. In this chapter, you'll learn more about vertebrates such as these. You'll find out that vertebrates are a diverse and fascinating group of animals. Q: What do puffer fish produce to protect itself? Choices: - teeth - enzymes - hormones - venom A:
(Answer)
venom
Ques: Answer the following question given this paragraph: Summary Bond order is the number of electron pairs that hold two atoms together. Single bonds have a bond order of one, and multiple bonds with bond orders of two (a double bond) and three (a triple bond) are quite common. In closely related compounds with bonds between the same kinds of atoms, the bond with the highest bond order is both the shortest and the strongest. In bonds with the same bond order between different atoms, trends are observed that, with few exceptions, result in the strongest single bonds being formed between the smallest atoms. Tabulated values of average bond energies can be used to calculate the enthalpy change of many chemical reactions. If the bonds in the products are stronger than those in the reactants, the reaction is exothermic and vice versa. Saylor URL: http://www. saylor. org/books.

Answer the following question given this paragraph: Fungi are simple eukaryotic organisms that consist of one or more cells. They include mushrooms and yeasts. Human diseases caused by fungi include ringworm and athlete's foot. Both are skin diseases that are not usually serious. A ringworm infection is pictured below ( Figure below ). A more serious fungus disease is histoplasmosis. It is a lung infection. Though fungal infections can be annoying, they are rarely as serious or deadly as bacterial or viral infections. Q: Ringworm and athlete's foot are human diseases caused by what simple organisms? Choices: - bacteria - insects - viruses - fungi A:
(A).
fungi
Ques:Answer the following question given this paragraph: Images in a plane mirror are reversed left and right but not reversed top and bottom. Q: Images in what type of mirror are reversed left and right but not reversed top and bottom? Choices: - concave - virtual - convex - plane mirror A:

Ans:plane mirror
Answer the following question given this paragraph: During a nuclear decay process that occurs by positron emission, a proton is converted into a neutron and a positron. The neutron remains in the nucleus, and the positron is expelled. Overall, the atomic number of the parent nucleus increases by one, and the mass number is unchanged. For example, carbon-11 emits a positron to become boron-11:. Q: What happens to the mass number during a nuclear decay process by positron emission? Choices: - it rises - it decreases - it increases - remains unchanged A:
remains unchanged
