ACTIVITY 9.2: Essay. Directions: Read the situation and identify the points of Darwin’s natural selection. There are 2 types of worms: worms that eat at night (nocturnal) and worms that eat during the day (diurnal). The birds eat during the day and seem to be eating ONLY the diurnal worms. The nocturnal worms are in their burrows during this time. Each spring when the worms reproduce, they have about 500 babies but only 100 of tthese 500 ever become old enough to reproduce.A.

Directions: Perform the task below based on your understanding on the topic " Mechanisms 'of Evolutionary Change" . There are four factors that can change the allele frequencies of a population namely Natural Selection, Mutations, Genetic Drift and Gene Flow. Make a creative outline summarizing the processes happened in these mechanisms of evolutionary change (use separate sheet if

TOPIC: The response of an HIV strain to antiviral drugs. Research your specific example of natural selection to better understand how and why the population has changed over time. Organize your information into the presentation format below. • Step by step explanation of how a population can change over time, using your example • Description of inherited variation within the population Explanation of why some individuals are better able to survive and produce offspring • A description of the adaptation that is being favored by natural selection • Data to support explanations
. Test Your Skills 1. Describe what is happening in figures 1-3. 1 3 b. Is the population of mice different in figure 3 than in figure 1? Explain why. c. Living things that are well adapted to their ervironment survive and reproduce. Those that are not well adapted don't survive and reproduce. An adaptation is any characteristic that increases fitness, which is defined as the ability to survive and reproduce. What characteristic of the mice is an adaptation that increased their Eitness?
Question:- Changes in environmental conditions can render previous adaptations as maladaptations. Describe an example of maladaptation in humans during the last 100,000 years. Your answer should include a discussion of the relevant environmental factors, fitness (in both environments), and specific variants (genotypes). Please explain and other useful info. Thanks

ACTIVITY 2 Patterns of Descent with Modification from Common Ancestors 1.Dog (Canis familiarizes) is a common pet at home. Using this species, create a diagram to show patterns of descent with modification of dog from its common ancestor. Answers can be in a form of drawing or word. Refer to the example (The descent of modification or evolution of cat)
Match the description with the correct term. • a common ancestor diversifies and the various species all have different adaptations • the idea that inherent variation in a population allows for certain traits to be selected for and carried on to future generations of the population experiencing an environmental pressure • a model suggesting the gradual change of a species in a linear fashion to form distinct species organisms that have a common ancestry but develop body parts that perform different functions • two populations become reproductively isolated (can no longer reproduce successfully) • the idea that different mating calls of birds used during mating season has led to different species of birds ✔ Choose... theory of natural selection. homologous structures gradualism biological barrier to reproduction speciation adaptive radiation Choose...

dictions: On Part II I The Rehpogs in the original population that stayed in the warm environment has maintained their original genetic diversity of 50% dominant alleles for thick purple fur and 50% recessive alleles for thin pink fur. Remember that the original population of Rehpogs lived on the ground in a relatively flat habitat. This group is called Population A. The population has increased to where there is not enough food for everyone. About half of this genetically diverse group of Rehpogs (Population B) was sent out by the leader to find a suitable new home in the uneven, rocky territory to the south. Population A stayed behind in the flat habitat. Unfortunately, an unexpected effect of the dominant allele for thick purple fur is vertigo. None of the Rehpogs noticed this associated trait before they moved to the uneven, rocky territory because these little creatures do not get hurt if they fall over on level ground. Sadly, when the thick purple furred Rehpogs walk on pathways…
