Cells are the fundamental unit of life.
All living things are cells or composed of cells.
The interior contents of cells in the cytoplasm.
Cell, in biology, the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed.
A single cell is often a complete organism in itself, such as a bacterium or yeast.
Other cells acquire specialized functions as they mature.
These cells cooperate with other specialized cells and become the building blocks of large multicellular organisms, such as humans and other animals.
The smallest known cells are a group of tiny bacteria called mycoplasmas; some of these single-celled organisms are spheres as small as 0.2 μm in diameter.
Largest cell ….
The largest single-celled organism is an animal
called Syringammina fragilissima, which can grow to a width of 4 inches.
– are highly folded, forming a complex network of tubes.
The biological science which deals with the study of structure, function, molecular organization, growth, reproduction, and genetics of the cells, is called cytology or cell biology
(Gr., kytos = hollow vessel or cell; logos = to discourse).
Much of cell biology is devoted to the study of structures and functions of specialized cells.
Individual cells that form our bodies can grow, reproduce, process information, respond to stimuli, and carry out an amazing array of chemical reactions.
Of all the living things, the human body in particular has been a source of curiosity by most of us. No doubt, the field of biology, anatomy and physiology provide us a clear venue to explore and understand it.

TITLE: Discuss the properties of life, basic chemical terminology, and molecules and compounds of a cell necessary for life.
Biology is the scientific study of life. It’s a subject that enormous scope and increases all the time. Which leads to many questions like: What is life? Or, let me put it to you this way, what distinguishes living things from non-living? Properties of Life: All living organisms share several key characteristics and/or function. Here you will find seven properties of life: order, response to the environment, reproduction, growth and development, regulation, homeostasis, and energyprocessing. If we analyze these seven characteristics we realize that it serves to define life. I’m going to start off by showing you what each property represents and the important role it plays in life.
(1).Order. Organisms are highly organized, coordinated structures that consist of one or more cells. Even very simple, single-celled organisms are remarkably complex: inside each cell, atoms make up molecules; these in turn make up cell organelles and other cellular inclusions. In multicellular organisms, similar cells form tissues. Tissues, in turn, collaborate to create organs (body structures with a distinct function). Organs work together to form organ systems. (2).
Response to the environment. Organisms can respond to diverse stimuli. For example, plants can grow toward a source of light, climb on fences and walls, or respond to touch. Even tiny bacteria can move toward or away from chemicals (a process called chemo taxis) or light (photo taxis). Movement toward a stimulus is considered a positive response, while movement away from a stimulus is considered a negative response. (3). Reproduction. Single-celled organisms reproduce by first duplicating their DNA. They then divide it equally as the cell prepares to divide to form two new cells. Multicellular organisms often produce specialized reproductive germ line cells that will form new individuals. When reproduction occurs, genes containing DNA are passed along to an organism's offspring. These genes ensure that the offspring will belong to the same species and will have similar characteristics, such as size and shape. (4). Growth and Development. All organisms grow and develop following specific instructions coded for by their genes. These genes provide instructions that will direct cellular growth and development, ensuring that a species' young will grow up to exhibit many of the same characteristics as its parents. (5).Regulation. Even the smallest organisms are complex and require multiple regulatory mechanisms to coordinate internal functions, respond to stimuli, and cope with environmental stresses. Two examples of internal functions regulated in an organism are nutrient transport and blood flow. Organs (groups of tissues working together) perform specific functions, such as carrying oxygen ...

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

THINK ABOUT IT
Think about important news stories you’ve heard. Bird flu spreads
around the world, killing birds and threatening a human epidemic. Users
of certain illegal drugs experience permanent damage to their brains
and nervous systems. Reports surface about efforts to clone human
cells.
These and many other stories involve biology—the science that
employs scientific methodology to study living things. The Greek word
bios means “life,” and -logy means “study of.”

Characteristics of Living Things
What characteristics do all living things share?
Living things are made up of basic units called cells, are based on a
universal genetic code, obtain and use materials and energy, grow and
develop, reproduce, respond to their environment, maintain a stable
internal environment, and change over time.
5. Lesson OverviewLesson Overview Studying LifeStudying Life
Characteristics of Living Things
Biology is the study of life. But what is life?
No single characteristic is enough to describe a living thing. Also,
some nonliving things share one or more traits with organisms.
Some things, such as viruses, exist at the border between organisms
and nonliving things.
6. Lesson OverviewLesson Overview Studying LifeStudying Life
Characteristics of Living Things
Despite these difficulties, we can list characteristics that most living things
have in common. Both fish and coral, for example, show all the
characteristics common to living things.
7. Lesson OverviewLesson Overview Studying LifeStudying Life
Characteristics of Living Things
Living things are based on a universal genetic code.
All organisms store the complex information they need to live, grow, and
reproduce in a genetic code written in a molecule called DNA.
That information is copied and passed from parent to offspring and is
almost identical in every organism on Earth.
8. Lesson OverviewLesson Overview Studying LifeStudying Life
Characteristics of Living Things
Living things grow and develop.
During development, a single fertilized egg divides again and again.
As these cells divide, they differentiate, which means they begin to
look different from one another and to perform different functions.
9. Lesson OverviewLesson Overview Studying LifeStudying Life
Characteristics of Living Things
Living things respond to their environment.
A stimulus is a signal to which an organism responds.
For example, some plants can produce unsavory chemicals to ward
off caterpillars that feed on their leaves.
10. Lesson OverviewLesson Overview Studying LifeStudying Life
Characteristics of Living Things
Living things reproduce, which means that they produce new similar
organisms.
Most plants and animals engage in sexual reproduction, in which cells
from two parents unite to form the first cell of a new organism.
11. Lesson OverviewLesson Overview Studying LifeStudying Life
Characteristics of Living Things
Other organisms reproduce through asexual reproduction, in which
a single organism produces offspring identical to itself.
Beautiful blossoms are part of an apple tree’s cycle of sexual
reproduction.
12. Lesson OverviewLesson Overview Studying LifeStudying Life
Characteristics of Living Things
Living things maintain a relatively stable internal environment, even
when external conditions change dramatically.
All living organisms expend energy to keep conditions inside their
cells within certain limits. This conditionprocess is called
homeostasis.
For example, specialized cells help leaves regulate gases that
enter and leave the plant.
13. Lesson OverviewLesson Overview Studying LifeStudying Life
Characteristics of Living Things
Living things obtain and use material and energy to grow, develop,
and reproduce.
The combination of chemical reactions through which an organism
builds up or breaks down materials is called metabolism.
For example, leaves obtain energy from the sun and gases from the
air. These materials then take part in various metabolic reactions
within the leaves.

Characteristics of Living Things
Living things are made up of one or more cells—the smallest units
considered fully alive.
Cells can grow, respond to their surroundings, and reproduce.
Despite their small size, cells are complex and highly organized.
For example, a single branch of a tree contains millions of cells.
15. Lesson OverviewLesson Overview Studying LifeStudying Life
Characteristics of Living Things
Over generations, groups of organisms evolve, or change over time.
Evolutionary change links all forms of life to a common origin more
than 3.5 billion years ago.
16. Lesson OverviewLesson Overview Studying LifeStudying Life

Evidence of this shared history is found in all aspects of living and fossil
organisms, from physical features to structures of proteins to sequences
of information in DNA.
For example, signs of one of the first land plants, Cooksonia, are
preserved in rock over 400 million years old.

Big Ideas in Biology
What are the central themes of biology?
The study of biology revolves around several interlocking big ideas: The
cellular basis of life; information and heredity; matter and energy; growth,
development, and reproduction; homeostasis; evolution; structure and
function; unity and diversity of life; interdependence in nature; and science
as a way of knowing.
19. Lesson OverviewLesson Overview Studying LifeStudying Life
Big Ideas in Biology
All biological sciences are tied together by “big ideas” that overlap and
interlock with one another.
Several of these big ideas overlap with the characteristics of life or the
nature of science.
20. Lesson OverviewLesson Overview Studying LifeStudying Life
Cellular Basis of Life
Living things are made of cells.
Many living things consist of only a single cell and are called
unicellular organisms.
Plants and animals are multicellular. Cells in multicellular organisms
display many different sizes, shapes, and functions.
21. Lesson OverviewLesson Overview Studying LifeStudying Life
Information and Heredity
Living things are based on a universal genetic code.
The information coded in your DNA is similar to organisms that lived 3.5
billion years ago.
The DNA inside your cells right now can influence your future—your risk
of getting cancer, the amount of cholesterol in your blood, and the color
of your children’s hair.
22. Lesson OverviewLesson Overview Studying LifeStudying Life
Matter and Energy
Life requires matter that serves as nutrients to build body structures,
and energy that fuels life’s processes.
Some organisms, such as plants, obtain energy from sunlight and take
up nutrients from air, water, and soil.
Other organisms, including most animals, eat plants or other animals to
obtain both nutrients and energy.
The need for matter and energy link all living things on Earth in a web of
interdependent relationships.
23. Lesson OverviewLesson Overview Studying LifeStudying Life
Growth, Development, and Reproduction
All living things reproduce. Newly produced individuals grow and
develop as they mature.
During growth and development, generalized cells typically become
more different and specialized for particular functions.
Specialized cells build tissues, such as brains, muscles, and digestive
organs, that serve various functions.
24. Lesson OverviewLesson Overview Studying LifeStudying Life
Homeostasis
Living things maintain a relatively stable internal environment.
For most organisms, any breakdown of homeostasis may have
serious or even fatal consequences.
Specialized plant cells help leaves regulate gases that enter and

Evidence of this shared history is found in all aspects of living and
fossil organisms, from physical features to structures of proteins to
sequences of information in DNA.
Evolutionary theory is the central organizing principle of all
biological and biomedical sciences.
27. Lesson OverviewLesson Overview Studying LifeStudying Life
Structure and Function
Each major group of organisms has evolved its own collection of
structures that have evolved in ways that make particular functions
possible.
Organisms use structures that have evolved into different forms as
species have adapted to life in different environments.
28. Lesson OverviewLesson Overview Studying LifeStudying Life
Unity and Diversity of Life
Life takes a variety of forms. Yet, all living things are fundamentally
similar at the molecular level.
All organisms are composed of a common set of carbon-based
molecules, store information in a common genetic code, and use
proteins to build their structures and carry out their functions.
Evolutionary theory explains both this unity of life and its diversity.
29. Lesson OverviewLesson Overview Studying LifeStudying Life
Interdependence in Nature
All forms of life on Earth are connected into a biosphere, or “living
planet.”
Within the biosphere, organisms are linked to one another and to the
land, water, and air around them.
Relationships between organisms and their environments depend on
the cycling of matter and the flow of energy.

Science as a Way of Knowing
The job of science is to use
observations, questions, and
experiments to explain the natural
world in terms of natural forces and
events.
Successful scientific research
reveals rules and patterns that can
explain and predict at least some
events in nature.
31. Lesson OverviewLesson Overview Studying LifeStudying Life

Building the Tree of Life
Biologists have discovered and identified roughly 1.8 million different
kinds of living organisms, and researchers estimate that somewhere
between 2 and 100 million more forms of life are waiting to be
discovered around the globe. This paleontologist studies signs of
ancient life—fossilized dinosaur dung!
38. Lesson OverviewLesson Overview Studying LifeStudying Life
Building the Tree of Life
In addition to identifying and cataloguing all these life forms, biologists
aim to combine the latest genetic information with computer technology

Ecology and Evolution of Infectious
Diseases
The relationships between hosts and pathogens are dynamic and

Safety
Scientists working in a laboratory or in the field are trained to use safe
procedures when carrying out investigations.
Whenever you work in your biology laboratory, you must follow safe
practices as well.
Before you start each activity, read all the steps and make sure that you
understand the entire procedure, including any safety precautions.
The single most important safety rule is to always follow your teacher’s
instructions. Any time you are in doubt about any part of an activity, ask
your teacher for an explanation.
48. Lesson OverviewLesson Overview Studying LifeStudying Life
Safety
Because you may come in contact with organisms you cannot see, it
is essential that you wash your hands thoroughly after every scientific
activity. Wearing appropriate protective gear is also important while
working in a laboratory.
Remember that you are responsible for your own safety and that of
your teacher and classmates. If you are handling live animals, you are
responsible for their safety too.
