| Producing the first transgenic plant.
Which of the following best demonstrates evolution? | Your pet walks to the door when it hears your car in the driveway. | | A crop has a higher yield after fertilizer is added. | | Over time, a gene for disease resistance becomes more frequent in a population of plants. | | A giraffe with a longer neck survives a drought year, while one with a shorter neck does not. | | A houseplant is moved to a sunnier location and it starts to grow more vigorously.
What is the difference between genetically-modified and transgenic crops? | Genetically-modified crops are produced using modern techniques, while transgenic crops are produced through classical breeding. | | Transgenic crops are illegal, while genetically-modified crops are not. | | Genetically-modified crops are a type of transgenic crop specifically bred for high yield. | | Transgenic crops are a type of genetically-modified crops, in which scientists have inserted genes from another species. | | The repeated domestication of grasses (i.e., cereals) and legumes across the globe is likely because: | Human populations were often starving, and needed an additional food source | | Only grasses, not legumes, were repeatedly domesticated | | Early technologies allowed early agriculturalists the ability to communicate with each other over long distances to discuss what plants were best for domestication. | | Both already possessed all of the traits needed for domestication | | Both contain almost all of the amino acids our bodies need to build proteins. | What is one type of information that can be gathered by archeologists who are studying dental caries (cavities) of ancient populations? | The time of year the person died | | How many children the person had | | The type of plants they may have been consuming | | The types of tools used for planting/harvesting grains | | How many conflicts they have been part of
Which of the following types of agriculture can be practiced in an urban setting? | Alternative farms (crickets, caterpillars, other arthropods) | | All of these types of agriculture can be practiced in an urban setting | | In discussing the origin of agriculture, the term demographic stress refers to: | That the stresses on pre-domesticated plant species led to the development of traits that result in the "domestication syndrome” | | Lower productivity of un-cultivated plants due to late-Pleistocene cooling. | | Hobbes's assertion that hunter-gatherer groups did not posses the knowledge or skills to develop agriculture. | | The situation where human populations are greater than the carrying capacity of the environment. | | A higher incidence of religious practice in societies following the transition from hunting and gathering to agriculture. | In what way did Harlan’s theory give rise to Diamond’s theory? | It recognized that agricultural societies were healthier and better fed than hunter-gatherer societies. | | It recognized agriculture might have developed by different mechanisms in different parts of the world. | | It recognized the reason agriculture did not develop in certain parts of the world was because people lacked the intelligence or skill. | | Both make the assumption that hunter-gatherers were (and still are) superior to agriculturists. | | It is a basic case of scientific plagiarism - Diamonds theory is identical to Harlans theory.
Plant species that rely on _______ pollination produce much more pollen than those using other methods. | Brussel sprouts, cabbage, broccoli and cauliflower are all different varieties of the same species, Brassica oleracea. This group of plants demonstrates that crop breeding can lead to: | Low within variety and high between variety diversity | | High between variety diversity | | Low within variety diversity | | High within variety and high between variety diversity | | High within variety and low between variety diversity | If a plant can grow well all by itself in the wild, yet still retains desirable agronomic traits, the plant is ____________________. Choose the single best answer The inability of plants to move makes it difficult for them to: | Disperse seeds and defend themselves. | | Disperse seeds, defend themselves, and create oxygen. | |
