Constellations were important to people, like the Ancient Greeks. People who spent a lot of time outdoors at night, like shepherds, named the constellations. They told stories about them. Pictured below is one of the most easily recognized constellations ( Figure below ). The ancient Greeks thought this group of stars looked like a hunter. They named it Orion, after a great hunter in Greek mythology. Q: What do you call the patterns and groups of stars in the sky that ancient people observed and made stories about? Choices: - planets - meteors - asteroid fields - constellations A:
constellations

Ques:Answer the following question given this paragraph: Wallace and Darwin both observed similar patterns in other organisms and independently conceived a mechanism to explain how and why such changes could take place. Darwin called this mechanism natural selection. Natural selection, Darwin argued, was an inevitable outcome of three principles that operated in nature. First, the characteristics of organisms are inherited, or passed from parent to offspring. Second, more offspring are produced than are able to survive; in other words, resources for survival and reproduction are limited. The capacity for reproduction in all organisms outstrips the availability of resources to support their numbers. Thus, there is a competition for those resources in each generation. Both Darwin and Wallace's understanding of this principle came from reading an essay by the economist Thomas Malthus, who discussed this principle in relation to human populations. Third, offspring vary among each other in regard to their characteristics and those variations are inherited. Out of these three principles, Darwin and Wallace reasoned that offspring with inherited characteristics that allow them to best compete for limited resources will survive and have more offspring than those individuals with variations that are less able to compete. Because characteristics are inherited, these traits will be better represented in the next generation. This will lead to change in populations over generations in a process that Darwin called "descent with modification. " Papers by Darwin and Wallace (Figure 11.3) presenting the idea of natural selection were read together in 1858 before the Linnaean Society in London. The following year Darwin's book, On the Origin of Species, was published, which outlined in considerable detail his arguments for evolution by natural selection. Q: What did darwin call the evolutionary concept of change in populations over generations? Choices: - formation with modifications - reproduction with modifications - metabolism with modifications - descent with modifications A:

Ans:descent with modifications
