Answer #1

The different species of Pteranodon have been differentiated on the basis size and shape of their crests which is an example of species identification on the basis of morphological features and hence is called morphological species concept.

So option a is correct.

    1. A population of monkeys on an island in the Amazon river is preyed upon by margays (a type of small cat).  Within this population the largest monkeys are too big for the margays to catch and the smallest monkeys are too agile for the margays to catch. Thus the mid-size monkeys have the lowest fitness. Over time this population could potentially split into two populations and two separate species of large and small monkeys. What type of speciation would occur...

    How do biologists use the parsimony method when constructing a phylogenetic tree? If there is only one true evolutionary history for any group of species, discuss the possible reasons why the taxonomists analyzing genetic data (e.g., DNA sequence data) versus those analyzing morphological data may suggest different phylogenetic relationships among the same exact group of species? 4) Describe how the agnathans differ from other fish? Compare the morphology and natural history of hagfishes and lampreys. Your answer should include (at...

    QUESTION 56 The ecological impacts of warming are manifold. One response has been to reduce seed production my many plants. An example involving phonology and mutualism for this would be: A Warming accelerates the timing of flowering but not the time for arrival by polinators and thus reduces pollination and subsequent sood production An insect increases its metabolic rate from warming, requiring it to eat more plants, which reduces sood production Warming induces greater water stress in the summer and...
