1. The diagram shows the population curve (y-axis) vs time (x-axis). Which line/curve best describes the theory of natural selection of Charles Darwin? 2. The diagram shows the population curve (y-axis) vs time (x-axis). Which curve represents the scenario described by Thomas Malthus "the populations with unlimited natural resources grow very rapidly, after which population growth decreases as resources become depleted". 3. The diagram shows the population curve (y-axis) vs time (x-axis). Which curve best represents the growth of bacteria? 4. The diagram shows the population curve (y-axis) vs time (x-axis). Which line/curve acts as a moderating force in the growth rate by slowing it when resources become limited and stopping growth once it has been reached.
1.) 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. Which among the following is NOT a principle of natural selection? a. The DNA sequence of the organism will change. b. The characteristics of organisms are inherited or passed from parent to offspring. c. Offspring vary among each other about their characteristics, and those variations are inherited. d. More offspring are produced than can survive. 2. Tawilis is a freshwater sardine endemic only in the Taal Lake in Batangas province. After several eruptions of the Taal volcano in the 21st century, the sardine population mentioned above rapidly dropped up to 82%. What best describe this scenario? a. mutation b. migration c. natural selection d. genetic drift
11. A small group of finches from the mainland United States get blown off course during a hurricane and are focused to settle on an island off the coast of Georgia. Most of these birds have a recessive trait for yellow spots on their wings which is not a common trait among this speciet. Over several generations the entire population of these finches on the island have this expressive trait. This is an example of ____. A. cacogenesis B. anagenesis C. reproductive isolation D. the founder effect
Place the following elements in the strategy to control mosquito populations in the correct order from earliest to latest by numbering them from 1 to 5. a. Scientists genetically modify male mosquitoes in the lab. b. Mosquito offspring produced by the matings do not survive to adulthood. c. GM male mosquitoes mate with normal wild females. d. The mosquito population decreases dramatically. e. Scientists release GM male mosquitoes into the wild.
In Question 10p of Chapter 4, the genotype of parents of litters with the following phenotypes was determined as "Bbdd x bbDd." How was this phenotype determined based on the genotype: a. ) 4 brown, 4 black, 4 yellow and 4 cream 4 brown (4 B_D_) , 4 black (4 B_dd), 4 yellow (4 bbD_), 4 cream (4 bbdd) Hoping to get feedback in the shortest possible time.
Which of these statements about the virulence of rabbit myxoma virus is TRUE?A. Rabbit myxoma virus needed to become less virulent so it could coexist with its rabbit hosts.B. Directional selection favored a coevolutionary escalation where resistance evolved in rabbits and less virulence evolved in the virus.C. Rabbit myxoma virus became less virulent over time because natural selection favored strains that did not immediately kill the rabbit hosts, enhancing the likelihood of spreading and infecting other rabbits.D. None of the above is a true statement.
Which of the following is not a component of Darwins theory as he understood it? a. Some individuals in a population survive longer than others. b. Some individuals in a population reproduce more thanothers. c. Heritable variations allow some individuals to compete moresuccessfully for resources. d. Mutations in genes produce new variations in a population. e. Some new variations are passed to the next generation.

Use the terms: insecticide resistance/resistant, natural selection, favorable trait, reproduce, mutation/sexual reproduction Use this sentence starter: At the beginning the daily mosquito count (increased/decreased) until month _, then it started to (increase/decrease). This occurred because.. Use NUMBERS FROM THE GRAPH
Maria has a sore throat. Her father takes her to the doctor and she is given an antibiotic. After ten days, Maria is still sick. Use the model seen here and describe what has happened to Maria in terms of natural selection. A) The medicine causes some bacteria to become resistant to antibiotics. They survive and reproduce. B) Some of the bacteria are resistant to the antibiotic. They survive and reproduce, keeping Maria sick. C) After being subjected to the antibiotics, some bacteria change and they can survive the medicine. Maria remains sick. D) In a population of bacteria, variation exists. The bacteria that have increased resistance to medicine outcompete the non-resistant bacteria for food. Not Graded
1. Which of these populations has all the characteristics needed to evolve by natural selection? A. a population of lizards may be brown or red. The temperature of the eggs determines the color of the baby lizards, and a brown parent lizard is equally likely to give birth to either color of offspring. B. a population of spiders includes individuals that build their webs in triangle shapes and others that build their webs in round shapes. They inherit their web-building strategies from their parents and all shapes are equally successful at catching insects. C. some gazelles are capable of running faster than others, a skill that is partially genetic Faster gazelles tend to live longer and have more offspring. A. Population A B. Population B C. Population C 2. Your friend asks you "If evolution is real, why aren't humans perfectly adapted by now! why do people still get heart disease and cancer and die?" Which of these would be an accurate response you could give? A. Evolution only…
1.) Suppose that the frequency of a recessive allele is found to be 0.30. When the same population is sampled five years later, the frequency of the recessive allele is found to be 0.20. Do these findings indicate that the Hardy-Weinberg principle is false? Justify your response. 2.) Cystic fibrosis is an inherited recessive disorder that causes especially thick mucus to build up in the lungs and digestive tract. The mucus makes it difficult to clear micro-organisms from the airways, so people with cystic fibrosis are prone to dangerous respiratory infections. Among Caucasians, about one in every 3000 newborns is affected by this condition. Determine the frequency of the cystic fibrosis allele among Caucasians. What proportion of this population would you expect to be heterozygous carriers of the cystic fibrosis allele? Express your answers as decimals.
