Answer the following question given this paragraph: transient males. Since these loyal males already bond and cooperate with females, it may well be a simple matter for them to bond and cooperate with each other. In a semi-counter intuitive manner, the ability to bond with males could be selected for based on its effect on reproductive success with females. On the other hand, a male that commits himself to a cooperative (loyal and exclusive) arrangement with a female necessarily limits his interactions One of the most robust and reliable findings in with other females. This implies that he will attempt to insure the scientific literature on interpersonal that the offspring he is raising are genetically related to him. attraction is the overwhelming role played by physical attractiveness in defining the ideal Of course, another possibility is that a loyal male may be romantic partner (Hatfield & Sprecher, 1986; attractive to multiple females, who in turn compete for his Jackson, 1992). Both men and women express attention and loyalty. Clearly the outcome of such interactions marked preference for an attractive partner in a is influenced by how many females can the male effectively non- committed short-term (casual, one night stand) relationship (Buss & Schmitt, 1993). protect (that is, improve their reproductive success). The situation quickly gets complex and many competing strategies are possible. Different species make different choices depending upon their evolutionary history and environmental constraints. As we noted above, secondary sexual characteristics, that is, traits that vary dramatically between the two sexes, serve to advertise various traits, including heath, loyalty, robustness, and fertility. The size and symmetry of a beetle's or an elk's antlers or a grasshopper's song communicate rather clearly their state of health.192 The tail of the male peacock is a common example, a male either has large, colorful and symmetrical tail, all signs of a health or it does not there is little room for ambiguity. These predictions have been confirmed... Q: The size and symmetry of a beetle's or an elk's antlers or a grasshopper's song communicate rather clearly their state of what? Choices: - society - problem - need - health A:
health

Bacteria live in virtually all environments on Earth. Archaea live everywhere on Earth, including extreme environments. Q: Where on earth do bacteria live? Choices: - skin - water - blood - all environments A:
all environments

Answer the following question given this paragraph: There are other units in chemistry that are important, and we will cover others in the course of the entire book. One of the fundamental quantities in science is temperature. Temperature is a measure of the average amount of energy of motion, or kinetic energy, a system contains. Temperatures are expressed using scales that use units called degrees, and there are several temperature scales in use. In the United States, the commonly used temperature scale is the Fahrenheit scale (symbolized by F and spoken as "degrees Fahrenheit"). On this scale, the freezing point of liquid water (the temperature at which liquid water turns to solid ice) is 32F, and the boiling point of water (the temperature at which liquid water turns to steam) is 212F. Science also uses other scales to express temperature. The Celsius scale (symbolized by C and spoken as "degrees Celsius") is a temperature scale where 0C is the freezing point of water and 100C is the boiling point of water; the scale is divided into 100 divisions between these two landmarks and extended higher and lower. By comparing the Fahrenheit and Celsius scales, a conversion between the two scales can be determined: C=(F32)59 Saylor URL: http://www. saylor. org/books.
