tree growing in complacency? 19. This mature black spruce tree was growing to the west of
Hudson Bay, and it was cut in 1975. The rings of the northern boreal forest are too narrow to see

typically have 6 pairs of homologous chromosomes, 5 pairs of autosomes and 1
pair of sex chromosomes. C. elegans exist as two different sexes . About 99.98%
of C. elegans are self-fertilizing hermaphrodites and the other 0.02% are non-

During fertilization, these two cell types are brought together to produce a

C++ Deviation from Average (Recursion) Instructions Step 1- Write a.pdfNIRMALJAI08
C++
Deviation from Average (Recursion)
Instructions
Step 1:
Write a recursive function called Deviation which passes array A and Dev as arrays with size n
and average, a floating point, as two other parameters. The function calculates the deviation (not
standard deviation), that is the difference between an element and average, for each element and
stores the deviation in array Dev[]. Both negative and positive differences are acceptable. Use
the average function below in (Step 2) to calculate average and pass it as input for the last
parameter. The function declaration (or signature) is:
void Deviation(int A[], double Dev[], int n, double average)
Step 2:
To help the function Deviation function use or pass the average value, write a function called
average which passes an array A, the size n, the size which is constant and the accumulating sum
which is already set to 0 to begin with. The function uses tail recursion approach to calculate the
average as floating-point and returns it. You must typecast the calculation into floating-point
when calculating. The function declaration is:
double average(int A[], int n, const int size, int sum = 0)
For this algorithm, you are required to implement it recursively.
Step 3:
In the main function, use two arrays where A stores integers and B stores floating-point numbers.
Using the functions, determine the deviations of each element from the mean, then display the
differences from array B..

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
