Question
1. Echolocation is the ability to use sound waves that bounce of off objects to locate those objects. Bats and dolphins both have the ability ta echolocate. However, this is not a trait that they inherited from a common ancestor. Therefore, the ability of bats and dolphins to echolocate is an example of A. B. a homologous trait a homoplastic trait 2. You observe a single cell organism under the microscope and notice that it lacks a nuclear envelope. What other information would be useful in classifying this organism into one of the three domains? MULTIPLE ANSWERS CAN BE CHOSEN! A. It contains a circular chromosome. B. Its cell membrane contains fatty acid. C. Its cell wall lacks RRdAR D. It can exchange genetic information by transduction, transformation, and conjugation. Imagine a population of dragons with green and blue skin. Blue is dominant to green. There are 65 bepozexRuA dominant individuals, 25 heterozygous individuals, and 10 homozygous recessive individuals. Which of the following is the frequency of the recessive allele for this population of dragons? 3. A. 0.78 B. 0.65 C. 0.25 D. 0.23 4. Monarch flycatchers are birds. There are two different populations of Monarch flycatchers on the Solomon Islands. One population, called black flycatchers, has all black feathers. The other population, called chestnut-bellied flycatchers has black feathers with a chestnut colored belly. The phylogenetic tree of birds related to Monarch flycatchers is shown below. Each tip of the tree shows a male and female bird for that taxon. The location of chestnut-bellied flycatchers and black flycatchers on the tree are labeled. Chestnut-bellied flycatchers Black flycatcher Rennell shrikebill A. No B. Not enough informationExplanation / Answer
Answer 1. Option B
The given example is a type of convergent evolution and the cladistic term for the same phenomenon is homoplasy. The other two options, i.e. synapomorphy and homology is used for organisms which have evolved from a common ancestor.
