(05.04 MC)In the early 1700s Linnaeus came up with a new system of classification of living things that eventually replaced the one that had been used since Aristotle developed it in ancient Greece about 2000 years earlier. Why was a change necessary?

(05.02 MC)Which of the following is correct about mutations and genetic variation?

(06.01 MC)In the classification of organisms by kingdom, all prokaryotes are grouped together in the kingdom Monera. Genetic research, however, led to the separation of prokaryotes into two domains, Archaea and Eubacteria. Which of the following best describes similarities between Archaea and Eubacteria?

(06.01 MC)In the five-kingdom classification system, all prokaryotes belong to the kingdom Monera. Which of the following best explains a reason why prokaryotes were separated into different domains, Eubacteria and Archaea?

(06.01 MC)The smallest of the single-celled organisms that assist with decomposition in the soil are most likely to have which of the following characteristics?

(06.01 MC)In the early classification system, all bacteria were classified in one kingdom. Bacteria was later broken up into two separate kingdoms, Eubacteria and Archaea. Which of the following best explains a reason for this change?

A simply supported beam with dimensions of b = 10 in., h = 28 in., d = 25.5 in., and L = 21 ft supports a uniform service (unfactored) dead load consisting of its own weight plus 1.3 kips/ft and a uniform service (unfactored) live load of 1.1 kips/ft. The concrete is normal-weight concrete. Determine the moment due to the factored loads, Mu.      

(05.02 MC)Woolly mammoths were grass-eating mammals that resembled elephants but with heavy coats, large tusks, and small ears that made them suited for extremely cold weather of the ice age. In addition to hunting by humans, which other conditions may have caused woolly mammoths to become less reproductively successful and eventually become extinct at the end of the last ice age?

(05.01 LC)If two different animal species are found to go through equivalent stages of embryonic development until the very last stage, which conclusion would this phenomenon support?

(05.01 MC)How might a comparison of the anatomy of two closely related animals, such as lizards and snakes, provide information about their evolutionary history?
