Mitosis is one of the process which differentiate living organisms from non living things. this process consists of this phases Interphase, Prophase, Metaphase, Anaphase and Telophase. The results of the cell division is two identical daughter cells. mitosis takes place in every somatic cell except in the sex cells such as egg cell and sperm cell. the process of mitosis is a cycle meaning that it is continuous from each cell. Rudolf Virchow described mitosis with a simple statement "every cell from a cell".

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

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.
4. There are two types of cells. They are :
1)Vegetative cells
2)Reproductive cells
The cells which help in growth are called vegetative
cells.
The cells that help in reproduction are called
reproductive cells.
5. In every cell, there are a few microscopic
structures in the cytoplasm. They are called
organelles.
In cell division, centrioles and nucleus play
an important role.
9. PROPHASE
Centrioles
have changed to star shaped
structures called asters.
In between the asters, spindle fibers are
formed.
Chromatin network has changed to
chromosomes.
Nucleolus has disappeared, nuclear
membrane has disappeared.
10.
11. METAPHASE
0 The chromosome has two parallel
strands called chromatids.
0 The chromatids are held together
by centromere.
12.
13. ANAPHASE
Chromatids of chromosomes have divided.
Thus daughter chromosomes are formed.
Daughter chromosomes are pulled equally to both
poles.
This results in equal cells.
The mother cell has same number of chromosomes
as daughter cells.
14.
15. Two
daughter nuclei are formed.
Chromosomes have changed to chromatin
network.
Nucleolus has reappeared.
Nuclear membrane has reappeared.
Thus the cell divides into two new daughter
cells.
16.
17. SEXUAL REPRODUCTION
In sexual reproduction, the cell division process is known as
meiosis.
MEIOSIS
MEIO
SIS I
MEIO
SIS II
19. PROPHASE I
Centrioles have changed to star shaped
structures called ASTERS. In between the asters,
spindle fibers are formed.
Chromatin network has changed to
chromosomes.
Paternal and maternal chromosomes have
pared with each other. The inner chromatids
have exchanged their segments with each other.
Nucleolus and nuclear membrane have
disappeared.
20.
21.
Chromosomes are arranged at the center of
the cell.
Asters have moved to both poles of the cell.
Spindle fibers are attached to the centromere
of the chromosome.
22.
23. Homologous
chromosomes are pulled to
opposite poles of the cell.
In between the two sets of chromosomes
interzonal fibers are formed.
24.
25. TELOPHASE I
Two daughter nuclei are formed.
Chromosomes have changed to chromatin network.
Nucleolus reappears.
Nuclear membrane reappears.
28. PROPHASE II
Centrioles have changed to star shaped structures
called asters.
In between the asters, spindle fibers are formed.
Chromatin network has changed to chromosomes.
Nucleolus has disappeared, nuclear membrane has
disappeared.
29.
30. METAPHASE II
Asters have moved to all four corners
of the cell.
Chromosomes are arranged at the
center of the cell.
Aster fibers are holding the
centromere of the chromosomes.
31.
32. » Centromere of the chromosomes divides.
» Daughter chromosomes are pulled equally to all
four corners of the cell.
33.
34. TELOPHASE II
Four daughter nuclei are formed.
Chromosomes have changed to chromatin network.
Nucleolus has reappeared.
Nuclear membrane has reappeared.
35.
36. These
cells have only half the number of
chromosomes as that of their mother cell.
These
cells are the reproductive cells that
take part in sexual reproduction.
In
humans, the male reproductive cell is
called the SPERM and the female
reproductive cell is called the OVUM.
37. Thus cell division plays an important role in
growth, repair and healing of wounds and also
reproduction.
