**Transcription of Educational Text:****Question 7:**The same basic internal organs (kidneys, stomach, heart, and lungs) are found in frogs, birds, snakes, and rodents. This is primarily an example of _________.- A) Structural homology- B) Developmental homology- C) Genetic correlation- D) Inheritance of acquired characteristics**Question 8:**A farmer uses triazine herbicide to control pigweed in his field. For the first few years, the triazine works well and almost all the pigweed dies; but after several years, the farmer sees more and more pigweed. Which of these explanations best explains what happened?- A) The herbicide company lost its triazine formula and started selling poor-quality triazine.- B) Natural selection caused the pigweed to mutate, creating a new triazine-resistant species.- C) Triazine-resistant pigweed has less efficient photosynthesis metabolism.- D) Triazine-resistant weeds were more likely to survive and reproduce.**Question 9:**After the drought of 1977, researchers hypothesized that on the Galápagos island Daphne Major, medium ground finches with large, deep beaks survived better than those with smaller beaks because they could more easily crack and eat the tough *T. cistoides* fruits. A tourist company sets up reliable feeding stations with a variety of bird seeds (different types and sizes) so that tourists can get a better look at the finches. Which of these events is now most likely to occur to finch beaks on this island?- A) Evolution of yet larger, deeper beaks over time, until all birds have relatively large, deep beaks- B) Evolution of smaller, pointier beaks over time, until all birds have relatively small, pointy beaks- C) Increased variation in beak size and shape over time- D) No change in beak size and shape over time(No graphs or diagrams are present in this text.)

Introduction : Homologous organs are ones that have different functions while having similar architecture and a common ancestry. Analogous organs are those that share similar functions but have difference in the anatomical structures. Their origins are diverse.Q7. Option (A) is correct i.e Structural homology Explanation : The given case is of structural homology. It is because the basic structure of all these organ in the given organisms is similar. Hence, these are homologous organs. But, these organs have different functions in different organisms. Homologous organs may not necessarily perform the same function. Even, these structures do not have to look exactly the same in all these organisms. Developmental homology is the term used to describe anatomical resemblance resulting from a common embryological basis. The genetic correlation explains how two characteristics are related genetically. The traits that return in one or more people in the following or following generations is known as the phenomenon of acquired characteristic inheritance.
