Abstract Constructing a cladogram to determine the related species and the evolutionary history. Five mammalian species, which are dog, cat, horse, opossum, and deer, are distributed into cladogram based on morphological character and molecular data. This allows identifying the relatedness of these species. By their appearances of structures and behaviors, the dog and cat eat meet while deer and horse eat plants. This prediction leads to the hypothesis that car and dog are close whereas deer and horse are related.
A1. Quantitative genetic analyses (e.g., adoption studies, twin studies, family studies) Q2. The astonishing differences among dog breeds may indicate that they are many different species. Is this so? Explain.
Which category has more biological meaning—all brown birds or all birds descended from a hawklike ancestor? Why? Answer- “All birds descended from a hawklike ancestor” has more biological meaning, because not all brown birds are closely related based on evolutionary relationships. 18.2 Modern Evolutionary Classification Assessment 1a.How does evolutionary classification differ from traditional classification? Answer-Traditional classification grouped organisms according to overall similarities and differences.
In other words, rainbow trout and steelhead trout are the same species. The fish is sometimes called a salmon trout. Several other fish in the salmonid family are called trout, some are anadromous like salmon, whereas others are resident in freshwater only. Rainbow trout are predators with a varied diet, and will eat nearly anything they can grab. Their image as a selective eater is only a legend.
What kinds of clinical specimens may yield a mixed flora in bacterial cultures? Oral, Skin, or GI specimens 5. When more than one colony type appears in pure culture, what are the most likely sources of extraneous contamination? Individual colonies can be picked up on the inoculating loop, or straight wire and inoculated in to the fresh agar or brother media References Cowan, M. K. (2012).

5. Distinguish between animal and plant cells – structures in common/ structures unique to each. 6. Where is DNA located in a prokaryote cell? In a eukaryote cell?
Chapter 14 and 15 Study Guide Answers Section 14-1 VOCABULARY REVIEW 1. Biogenesis is the principle that all living things come from other living things. 2. Spontaneous generation is the supposed origin of living things from nonliving things. 3.
Causes and spread of infection 1. Understand the causes of infection 1. Identify the differences between bacteria, viruses, fungi and parasites Bacteria is living things that are neither animals or plants but a group that belongs to themselves. Bacteria are prokaryotic microorganism, which is a single cell that doesn’t contain nucleus. Viruses are a small infectious agent that can multiply only inside living cells of organisms.
From those that did survive this epic Ice Age, and from evolution of closely related animals, descended the cheetah that we recognize today. The cheetah has its own genus, however, it shares the same subfamily Felinae with numerous other animals, such as the cougar, lynx, jaguar, and bobcat. Currently, there are six subspecies of cheetahs, which include the Acinonyx jubatus hecki from West Africa, the Acinonyx jubatus jubatus from Southern Africa, the Acinonyx jubatus raineyii from East Africa, the Acinonyx jubatus soemmeringii from Central Asia, the Acinonyx jubatus velox, and the Acinonyx jubatus venaticus. Each of these subspecies can be distinguished by the subtle differences in their coats. Throughout history, cheetahs have been held in captivity and easily tamed.
Endangered Species One of the endangered species that has a rank as “Least Concern (LC)” on the IUCN Red List or Red Data List which the headquarters is in the United Kingdom. I would like to describe and tell where its habitat and distribution is. The animal that I want to talk about has a small body structure, is an omnivorous animal, and has an arboreal gliding possum that belong to the marsupial infraclass. This animal is a native to eastern and northern at the mainland Australia and it is also a native to New Guinea and the Bismarck Archipelago. Its scientific name is Petaurus breviceps and if we translate from this Latin word, it is called as “short-headed rope-dancer”, a reference to their canopy acrobatics.
