(Question)
Answer the following question given this paragraph: Butterfly fish like this one have "fake" eyespots. The eyespots may confuse larger predators long enough for the butterfly fish to escape. Q: Why do butterfly fish have fake eyespots? Choices: - aerodynamic purposes - mating purposes - random evolution - confuse predators A:
(Answer)
confuse predators
Ques: Answer the following question given this paragraph: No matter what the cell, all cells come from preexisting cells through the process of cell division. This is one of the core concepts of the Cell Theory. The cell may be the simplest bacterium or a complex muscle, bone, or blood cell. The cell may comprise the whole organism, or be just one cell of trillions. But whatever type of cell it is, it comes from a preexisting cell. And the new cell is genetically identical to its parent cell - that is, it has exactly the same DNA. Q: Where do cells come from? Choices: - sexual reproduction - mutations - nuclear fission - preexisting cells A:
Ans: preexisting cells
(Q).
Answer the following question given this paragraph: Carbohydrates, proteins, and lipids contain energy. When your body digests food, it breaks down the molecules of these nutrients. This releases the energy so your body can use it. Q: When your body digests food, it breaks down the molecules of nutrients and releases what? Choices: - waste materials - gas - calories - energy A:
(A).
energy
Ques:Answer the following question given this paragraph: A circuit that consists of one loop is called a series circuit . You can see a simple series circuit below. If a series circuit is interrupted at any point in its single loop, no current can flow through the circuit and no devices in the circuit will work. In the series circuit below, if one light bulb burns out, the other light bulb won't work because it won't receive any current. Series circuits are commonly used in flashlights. You can see an animation of a series circuit at this URL: http://regentsprep. org/regents/physics/phys03/bsercir/default. htm. Q: What do you call a circuit that consists of one loop, which if interrupted at any point, causes cessation of the whole circuit's electric current? Choices: - parallel circuit - constant circuit - dramatic circuit - series circuit A:

Ans:series circuit
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 have from three to six electrons in their outer energy level. Boron, pictured in the Figure below , is the only metalloid with just three electrons in its outer energy level. It tends to act like metals by giving up its electrons in chemical reactions. Metalloids with more than four electrons in their outer energy level (arsenic, antimony, and tellurium) tend to act like nonmetals by gaining electrons in chemical reactions. Those with exactly four electrons in their outer energy level (silicon and germanium) may act like either metals or nonmetals, depending on the other elements in the reaction. Q: How metalloids behave in chemical interactions with other elements depends mainly on the number of what, in the outer energy level of their atoms? Choices: - protons - positrons - neutrons - electrons A:
electrons
