Question 1. What two things do nodes represent on phylogenies? 
Nodes represent the most recent common ancestor of two or more descendant 
lineages and represent a speciation event. 
Question 2. Compare the branching patterns of phylogenies 1-3 above. Which 
statement below correctly describes the patterns among trees 1-3? 
Tree 1 = Tree 2 
Question 3. Which node represents the MRCA for taxa F and G? 
3 
Question 4. Which taxon or taxa is/are the sister group to E + F? 
D, G, H 
Question 5. If y...
1. Based on what you learned in lab 1, and assuming the relationships shown in figure 2.1 are 
correct, do ‘prokaryotes’ form a monophyletic group? 
No 
2. Based on figure 2.2, are the groups labeled “Archaea” monophyletic in the “two-domain” 
hypothesis? 
Yes 
3. Bacillus anthracis - d 
Vibrio cholerae - f 
Chlamydia trachomatis - e 
Lokiarchaeota - c 
Yersinia pestis - b

Pre-lab 6: Botanical Conservatory and Fungal Diversity (Score: 4.75/5) 
Question 1. Identify two reasons why maintaining a large, living plant collection is an 
important public and scientific resource. 
It lets us study different types of plants without having to travel all over the world and it teaches 
us better methods of conservation. 
Question 2. In figure 6.2 above, which season (X or Y) would correspond to winter at point 
A? 
Season X 
Question 3. On which side (left or right) of figure...
Pre-lab 4: Introduction to Plant Diversity I 
#1 Based on the figure is it correct to state that we understand deep relationships about 
Eukaryotes? How do we represent ambiguity in branching pattern on phylogenetic trees 
No because there is no first node, just several species that branch out as possible base taxa. The 
ambiguity is represented through the polytomy. 
#2 Do a little internet research and provide t
Pre-Lab 7: Introduction to Metazoa (Score: 
Question 1. Study the phylogeny of animals in figure 7.3. Where are humans on this 
phylogeny? What are the defining features of the phylum to which humans belong? 
Humans are on the chordata. The defining features are notochord, dorsal hollow nerve chord, and 
post-anal tail. 
Question 2. Study the phylogeny of animals in figure 7.3. What feature of the phylogeny 
supports the fact that deep relationships among animals remain unresolved? 
Polytomy:sho...

In the world of data structures, arrays play a crucial role in storing and organizing data. An array is a fundamental and versatile data structure that allows elements of the same type to be stored together. It serves as a foundation for more complex data structures and provides efficient access to elements. In this article, we will explore the concept of an array as an abstract data type (ADT) and its significance in data structures.
In this article, we will delve into the coding implementation of the insertion operation in arrays using the C language. Arrays are an essential data structure that allows us to store a collection of elements of the same type in contiguous memory locations. Understanding how to perform insertion operations on arrays is crucial for building efficient algorithms. We will explore the process step by step, discussing the logic and code required for successful array insertion in C.
Arrays are fundamental data structures that store a collection of elements in a contiguous block of memory. They provide efficient access to elements based on their indices and offer various operations for manipulating the data they hold. In this article, we will explore the common operations performed on arrays, including traversal, insertion, deletion, and searching. By understanding these operations, you will gain valuable insights into effectively working with arrays in data structures.
