Q1) Butterflies in Africa (species 1) pollinate just one species of flower with a short corolla reducing the variation in the length of the tongue of its pollinators. Butterflies in Europe (species 2) have variable lengths as they pollinate several different species of flowers. What is the mechanism shaping the length of the tongue in species 1?______ Q2) A variation on what morphological trait made the difference between life and death among all surviving finches in the draught of 1977?

Hello, I need help answering number 5 questions using the phylogeny below pls & thank you! 5.a) In the 1990s, when only mitochondrial DNA sequencing was available, geneticists claimed that there was no hybridization between humans (Homo sapiens) and Neanderthals (Homo neanderthalensis). Does the phylogeny shown above support the claim humans did not hybridize with Neanderthals in the past? How can you tell? b) Once nuclear DNA sequencing became fast and able to handle sequencing ancient DNA, living humans were found to have some Neanderthal genes. Is this finding clear evidence that some early modern humans did indeed hybridize with Neanderthals? Why? c) Did female H. sapiens hybridize with Neanderthal males to produce fertile offspring that then back-crossed with modern humans? What does the graph say about this? d) Did male H. sapiens hybridize with Neanderthal females that then back-crossed with modern humans? What does the graph say about this? Picture reference:…
17 The graph below represents the number of brown and green beetles collected in a particular ecosystem. Change in Coloration of Beetle Population Green beetles Brown beetles Time (years) The change observed in the number of green and brown beetles in the population is most likely due to (1) natural selection (2) selective breeding (3) gene manipulation (4) a common ancestor [4] Number of Individuals
which statement is false? 1)In the context of the evolution of senescence, the aphorism "live fast and die young" means that organisms with a more risky behavior will have a shorter life span. 2)Allopatric speciation is a type of speciation process that takes place in different geographic locations.

Please answer fast 1) Which if the following would NOT result in speciation? a. a male bird changed its mating dance, which changes which population of female birds he mates with b. an earthquake divides an area into two different geographical locations c. a volcano erupts producing a river of hot lava that cuts an island into halves d. a natural disaster kills off half the population, randomly altering the frequency of genes in the gene pool 2) which of the following is not true about mutations a. mutations from advantageous traits are more likely to be passes on to the next generation b. mutations are a change in an organisms DNA c. mutations are caused by changes in the environment d. natural selection favors some mutations over others, depending on the environment.
Aloes vs. Agaves Describe 3 general similarities (analogous structures) you observed between Aloes & Agaves. Now, identify a specific example -- 1 Aloe species and 1 Agave species -- that look especially similar. List their names and clearly describe how they are alike. What environmental pressures likely drove the development of these similar traits? Explain. Now, what makes these two families different? Fill in the table below based on the lab’s video lecture or your personal observations: Geographic origin Flowers (stalk length, color) # of reproductive events Leaf characteristics Aloes Agaves

Name: Date: Galapagos Finch Evolution (HHMI Biointeractive) - https://voutu be/mcM23M-CCog ~16 minutes 1. What is the "mystery of mysteries? 2. The Grants' study on the island of Daphne Major studied what organisms? 3. Where did the 13 species of finches on the islands come from? 4. How did the Grants catch the finches? 5. What features did they measure? 6. What happened in 1977 to the island? 7. What type of birds were more likely to survive after this event? 8. After the El Nino event in 1983, which birds were more likely to survive? 9. What keeps different species from mating on the Galapagos islands? 10. The most likely scenario explaining the different finches on the islands is that: a) different birds migrated to different islands b) one species evolved into many different species 11. Examine the graph below. Summarize what happened to the finch population between 1976 and 1978. 30 1976 Offspring 25- 20- 15- 10- 5- 7.3 7.8 8.3 8.8 9.3 9.8 10.3 10.8 11.3 40 1978 Offspring 30- 20-…
Choose correct option do explain. 1.Two closely-related finch species occasionally form hybrids. These hybrids tend to have beaks of an intermediate size to their parental species, which have large and small beaks respectively. What evidence would suggest there is extrinsic postmating isolation? Group of answer choices- a.The hybrids are not able to obtain enough food due to beak size b.The hybrids die early due to deleterious gene combinations c.The hybrids cannot reproduce with members of either parent species d.The hybrids cannot reproduce with other hybrids
