- The age structure diagrams for two hypothetical populations are shown below. Describe the growth rate of each population and discuss the current and future social and economic problems that each is likely to face.9) This chart shows the beak length of a population of finches in the Galapagos. The island was faced with a five year drought that made it difficult for birds to get water. If natural selection occurs, how would you predict the bird beak lengths to change? A) Only those with shorter beaks would survive. B) The population would not really change much. C) Only those with the longest beaks would survive. D) Those with medium-long beaks would increase most. Not GradedWhat is a cline? A. Discrete changes in genetic or phenotypic characteristics of a population over geographic space. B. Similar genetic or phenotypic characteristics of a population within the same geographic space. C. A gradual change in genetic or phenotypic characteristics of a population over geographic space. D. A gradual change in genetic or phenotypic characteristics of a population within a set geographic space.
- What is a cline? A. A gradual change in genetic or phenotypic characteristics of a population within a set geographic space. B. A gradual change in genetic or phenotypic characteristics of a population over geographic space. C. Similar genetic or phenotypic characteristics of a population within the same geographic space. D. Discrete changes in genetic or phenotypic characteristics of a population over geographic space.2)Which of the following best describes the difference between population size and population density? a)Population size measures the abundance of an organism, whereas population density measures the distribution b)Both variables measure abundance, but population density takes the into account the size of individuals, not just the number of individuals in the population c)Population size measures abundance, but population density measures how rapidly the size changes d)Population density measures the abundance of an organism, whereas population size measures the distribution e)None of these descriptions are correct1.) Which statement below is not consistent with a population in Hardy-Weinberg equilibrium? A.) Genetic drift is occuring. B.) Random mating is occuring. C.) Population size is large. D.) Migration is not occuring. 2.) Sickel cell anemia is an autosomal recessive genetic disorder. Because individuals affected by sickle cell anemia have defective hemoglobin proteins, their blood cannot transport oxygen properly. There appears to be a relationship between the incidence of malaria and sickle cell anemia. Individuals with sickle cell anemia are carriers of the sickle cell allele have some resistance to malaria. Malaria is caused by the parasite Plasmodium and is transmitted between humans by mosquitoes.” If scientists are successful in significantly reducing or eliminating malaria, the best prediction for what will happen to the allele for sickel cell anemia in the population is that it will: A.)not be affected by the elimination by malaria. B.) increase as its selective advantage…
- 1.In wildlife management, population numbers must be sustainable in that populations cannot exceed the environment’s ability to support them. Using the ∆N formula, consider the following: Coyotes are members of the Canis family, or dog family, that wanders natural or agricultural grasslands and temperate forest in search of rodents and small prey. Occasionally they will form packs to bring down a larger animal – perhaps a young, sick, or old deer. In this scenario, assume population numbers of coyotes have increased dramatically. a.Using your knowledge of the ∆N formula, provide four possible causes for this dramatic increase in population. b.Assume you are a wildlife manager and that the high coyote population is resulting in more human/coyote interactions. Steps need to be taken to correct the imbalance in coyotes. Provide two ecologically sound solutions to the problem.3.1 Answer this question, well detailed with a lot of information filled in. It is important to answer with more than 700 words please!!. 1.Create a table or graph of your choice to illustrate the difference in the size of the beluga population over a period of your choice. Explains the reasons why the size of the population is affected.1. In an attempt to save a rare endangered species, a number of zoos agree to begin a breeding program. A single pair of endangered species is expected to successfully rear an average of nine offspring per year, all of which survive to maturity (i.e., 4.5 per parent per generation). (A) Use the appropriate equation to calculate the number of individuals in the population after eight years.
- One concept of conservation biology is known as minimum viablepopulation. Some species’ populations are so fragmented andsmall that they may have very little genetic variability left. Withminimal genetic variation in the population, there is little likelihoodthat a population can adapt to an environmental threat, such as anew disease. Florida panthers are at or below the minimum viablepopulation level (estimated population less than 80). 1)Do you think that it is practical to use limited resources toconserve a population like the Florida panther? 2)Why?4.) Mang Berto breeds white mice in a cage. After a few generations, the breeder observes that the white mice are more aggressive towards each other, the young are less healthy, and more young white mice die. What do you think will happen to the population of white mice? a.) The population is not affected. b.) The population will remain the same. c.) The population will decrease. d.) The population will increase 5.) South Cotabato is known for its wide variety of fruits and other plant species that makes it really attractive to tourists. Which of the following classification of biodiversity value is described? a.) Direct economic value b.) Indirect economic value c.) Ethical/ cultural d.) both B and C 9.) If the number of births in a population is the same as the number of deaths in a population, what will happen to the growth of the population? a.) It will fluctuate. d.) It will increase. c.) It will stay the same. d.) It will decrease. 10.) Refers to the number of…6 The following question has two parts. First, answer Part A. Then, answer Part B. Part A: Which statement is a valid analysis about bison movement and the carrying capacity of Yellowstone National Park? A. The decrease in the northern herd's population is explained by its inability to migrate and the park's decreasing carrying capacity. B. The fact that bison only migrate in years of deep snow indicates that they have exceeded the park's carrying capacity. C. The carrying capacity for other animals found in Yellowstone has increased due to the bison's migration outside of the park. D. The movement of bison beyond park boundaries is not due to the bison population being too large for the park's carrying capacity. Part B: Which selection from the text provides evidence that directly supports this analysis? A. They move to lower elevation ranges during the winter months in response to snow accumulation and snowpack…
