For example, two male deer may compete for mates by clashing their antlers together. Q: What type of competition occurs between members of the same species? Choices: - exospecies - interspecies - interspecific - intraspecific A:
intraspecific

Answer the following question given this paragraph: Plants aren't the only organisms that use the energy of the sun to make food. Some bacteria can also perform photosynthesis. In fact, the first photosynthetic organisms on Earth were bacteria. Photosynthesis is just one of many ways that bacteria can obtain energy. Q: What were the first photosynthetic organisms on earth? Choices: - mosses - trees - fungi - bacteria A:
(Answer)
bacteria

Answer the following question given this paragraph: Electronegativity Differences between Metals and Nonmetals An element's electronegativity provides us with a single value that we can use to characterize the chemistry of an element. Elements with a high electronegativity ( 2.2 in Figure 7.15 "Pauling Electronegativity Values of the ") have very negative affinities and large ionization potentials, so they are generally nonmetals and electrical insulators that tend to gain electrons in chemical reactions (i. , they are oxidants). In contrast, elements with a low electronegativity ( 1.8) have electron affinities that have either positive or small negative values and small ionization potentials, so they are generally metals and good electrical conductors that tend to lose their valence electrons in chemical reactions (i. , they are reductants). In between the metals and nonmetals, along the heavy diagonal line running from B to At in Figure 1.24 "The Periodic Table Showing the Elements in Order of Increasing ", is a group of elements with intermediate electronegativities ( ~ 2.0). These are the semimetals, elements that have some of the chemical properties of both nonmetals and metals. The distinction between metals and nonmetals is. Q: What are metals and good electrical conductors that tend to lose their valence electrons in chemical reactions called? Choices: - stable metals - conservants - precious metals - reductants A:
(A).
reductants
Ques:Answer the following question given this paragraph: The large intestine is a wide tube that connects the small intestine with the anus. In adults, the large intestine is about 1.5 meters (5 feet) long. It is larger in width but shorter in length than the small intestine. Q: Which organ is a wide tube connecting the small intestine with the anus? Choices: - rectum - stomach - jejunum - large intestine A:

Ans:large intestine
