Question
Chapter 12.3, Problem 1MC
Summary Introduction
To determine:
The term adaptation, and the reasons that make adaptations more common within a population.
Concept Introduction:
Adaptations include behaviors, structures or physiological processes which can transfer from one generation to the next and makes the reproduction successful. Adaptations in an evolutionary sense, are characteristics that modify an individual’s ability to reproduce and survive.

- If mutation introduces a new allele into a population, what will happen to the frequency of the original alleles over generations? (Assume all alleles are adaptive.) a) The mutant allele will eventually be lost from the population. O b) Frequency of the original alleles will remain the same. c) Frequency of the original alleles will decrease. d) Frequency of the original alleles will increase.arrow_forwardWhich of the following is correct concerning adaptations? (Choose one.) Group of answer choices a)They always increase an organism's ability to survive better than other individuals in the population. b)They can increase an organism's ability to survive better or reproduce better than other individuals, but not both at the same time. c)They increase an organism's ability to reproduce better than other individuals in the population, in a given environment. d)They result from any mechanism of evolution.arrow_forwardHow is variation different from adaptation? * Variations are physical or behavioral traits that make an organism better suited to its environment while adaptation comes from random mutations. no answer Variation is a difference within an individual organism from the rest of the population. An adaptation is a feature that helps an organism survive in its environment. Adaptation is a difference within an individual organism from the rest of the population. A variation is a feature that helps an organism survive in its environment. Variation is always caused by mutation while adaptation is a heritable trait. Which of the following BEST explains Darwin's observation on populations of various species that seemed well-suited to their environment? * Species had been introduced to particular areas by humans on purpose. no answer Species might be able to adapt to their surroundings over time. The species Darwin saw were all related to each other. Some environments rarely ever change.arrow_forward
- What types of gene changes are most associated with the evolution of new anatomical features in a population?arrow_forward, can evolution be influenced by the starting population?arrow_forwardNatural selection and artificial selection or selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. Changes in genetic traits have occurred over generations through both natural selection and selective breeding although the occur through different means. What characterizes only artificial selection? Choose all that apply. A) chickens that lay larger eggs are favored B) selection increases the chances of surviving C) selection make a species stronger and fit for survival D) selection favors the desired characters in the new organismsarrow_forward
- Why does the response to selection often level off after many generations of selection?arrow_forwardIn what ways does evolution depend on transfer of information? In what ways does transfer of information depend on evolution?arrow_forwardAlthough natural selection is sometimes called the survival of the fittest, it is ultimately a process of: a) differential reproduction b) differential consumption c) differential migration d) differential mutationarrow_forward
