Animal are multicellular, heterotrophic eukaryotes that exhibit several key characteristics. They are heterotrophs, undergo sexual reproduction with diploid dominance, are multicellular eukaryotes that lack cell walls, and possess unique tissues like nervous and muscle. Their bodies are made of cells grouped into tissues that carry out specialized functions. Early development involves cleavage of the zygote followed by formation of a blastula and then gastrulation to form germ layers.

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).

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Epistemic Interaction - tuning interfaces to provide information for AI support
Intoranimal lecture 8
1. Animal are multicellular, heterotrophic eukaryotes with tissues that
develop from embryonic layers (with some exceptions)
• Several characteristics, taken together, sufficiently
define the group
– Heterotrophs
– Reproduce sexually, with the diploid stage usually
dominating the life cycle
– multicellular eukaryotes
– lack cell walls
– Their bodies are held together by structural proteins such as
collagen
– Nervous tissue and muscle tissue are unique, defining
characteristics of animals
– Tissues are group of cells that have a common structure,
function or both
2. Figure 32.2-1
Reproduction and Development
Zygote
Cleavage
Eight-cell
stage
After a sperm fertilizes an egg, the zygote undergoes rapid cell division called
cleavage
Cleavage leads to formation of a multicellular, hollow blastula
The blastula undergoes gastrulation, forming a gastrula with different layers of
embryonic tissues
5. More Animal Characteristics
• Many animals have at least one larval stage
i. A larva is sexually immature and morphologically
distinct from the adults
ii. A juvenile resembles an adult, but is not yet sexually
mature
• Most animals, and only animals, have Hox genes that
regulate the development of body form
i. Although the Hox family of genes has been highly
conserved, it can produce a wide diversity of animal
morphology
7. Animals can be characterized by
“body plans”
• Symmetry
– radial symmetry, with no front and back, or left or right
• Radial animals are often sessile or planktonic
– Two-sided symmetry is called bilateral symmetry
• Bilaterally symmetrical animals have
a dorsal (top) and a vental (bottom) side
A right and left side
Anterior (head) and posterior (tail) ends
Cephalization, the development of a head
9. Tissues
• Animal body plans also vary according to the
organization of the animal’s tissues
• Tissues are collections of specialized cells isolated
from other tissues by membranous layers
• During development, three germ layers give rise to
the tissues and organs of the animal embryo
1. Ectotherm is the germ layer covering the embryo’s surface
2. Endoderm is the innermost germ layer and lines the developing
digestive tube, called the archenteron
3. Mesoderm lies between the ectoderm and endoderm
10.
11. Body Cavities
• Sponges and a few other groups lack true tissues
• Diploblastic animals have ectoderm and endoderm
These include cnidarians and comb jellies
• Triploblastic animals also mesoderm; these include
all bilaterians
Most triploblastic animals possess a body cavity
A true body cavity is called a coelom and is derived
from mesoderm
– Coelomates are animals that possess a true coelom
• These include flatworms, arthropods, vertebrates and others

13. Coeloms
• The coelom is a cavity entirely surrounded
by mesoderm.
• A coelom provides a tube-within-a-tube
arrangement which has many advantages:
Allows visceral organs to grow independently
of the body wall
Fluid-filled coelom acts as a hydrostatic
skeleton in some animals (e.g. earthworms)
In mammals, the pericardial, peritoneal, and
pleural cavities are formed from the coelom
14. Protostome and Deuterostome Development
• Based on early development, many animals can
be categorized as having protostome
development or deuterostome development
– In protostome development, cleavage is spiral and
determinate
– In deuterostome development, cleavage is radial and
indeterminate
– With indeterminate cleavage, each cell in the early
stages of cleavage retains the capacity to develop into a
complete embryo
– Indeterminate cleavage makes possible identical twins,
and embryonic stem cells
15. In some embryos, the daughter blastomeres are either above or to
the side of each other. This is said to be radial-type symmetry.
In some embryos, the daughter blastomeres are not direclty over
or beside each other. They are tilted to the left or right 45 degrees.
This latter cleavage symmetry is said to be spiral.

17. New views of animal phylogeny are emerging
from molecular data
• Zoologists recognize about three dozen animal
phyla
• Phylogenies now combine morphological,
molecular, and fossil data
• Current debate in animal systematics has led to
the development of multiple hypotheses about the
relationships among animal groups
22. Points of Agreement
1. All animals share a common ancestor
2. Sponges are basal animals
3. Eumetazoa is a clade of animals
(eumetazoans) with true tissues
4. Most animal phyla belong to the clade Bilateria,
and some are bilarians
5. Chordates and some other phyla belong to the
clade Deuterostomia
23. Progress in Resolving Bilaterian
Relationships
• The morphology-based tree divides bilaterians into
two clades: deuterostomes and protostomes
• In contrast, recent molecular studies indicate three
bilaterian clades: Deuterostomia, Ecdysozoa, and
Lophotrochozoa
• Ecdysozoans shed their exoskeletons through a
process called ecdysis

28. • 12.1. Advent of
Multicellularity
• A. Advantages
• 1. Nature’s experiments with
larger organisms without
cellular differentiation are
limited.
• 2. Increasing the size of a cell
causes problems of exchange;
multicellularity avoids
surface-to-mass problems.
• 3.cell assemblages in sponges
are distinct from other
metazoans, but molecular
evidence shows common
ancestry
29. •B. Form and Function
•1. Body openings consist of
small incurrent pores or ostia
and a few excurrent oscula.
•2. Openings are connected by
a system of canals; water
passes from ostia to osculum.
•3. Choanocytes or
flagellated collar cells line
some of the canals.
–a. They keep the current
flowing by beating of
flagella.
–b. They trap and
phagocytize food particles
passing by.
•4. The framework of the sponge is
composed of needle-like calcareous or
siliceous spicules or organic spongin
fibers.
30. Phylum Porifera
A.
General Features
•
Porifera means "pore-bearing"; their sac-like bodies
are perforated by many pores.
•
They are sessile and depend on water currents to
bring in food and oxygen and carry away wastes.
•
Their body is a mass of cells embedded in gelatinous
matrix and stiffened by spicules of calcium carbonate
or silica and collagen.
•
They have no organs or tissues; cells are somewhat
independent.
•
Being sessile, they have no nervous or sense organs
and have simplest of contractile elements
•
They are aside from the mainstream of animal
evolution and thus they are often called Parazoa
•
Most of the 5000 species are marine, about 150 are
freshwater
•
Morphology changes with substratum, calmness of
water etc…
•
Sponges are ancient (fossils extend to Cambrian
Period
31. Lophotochozoa
• The clade Lophotrochozoa was identified by
molecular data
• Some develop a lophophore for feeding,
others pass through a trochopore larval stage
and a few have neither feature
• Ex: flatworms, rotifers, ectopracts,
brachiopods, molluscs, annelids
32. Phylum Cnidaria
• Two forms – Polyp and medussa
Polyps = sessile
Medusa = free swimming
• Cnidocytes = stinging cells on tentacles carnivores
• Gastrovascular cavity = central body cavity
33. Phylum Platyhelminthes
• Flatworms
• Diffusion replaces body system
Gas exchange takes place across the
surface, and protonephridia regulate the
osmotic balance
• Reproduce asexually
by fission
• Reproduce sexually
by cross fertilization
• flukes and tapeworms
34. Phylum Nematoda
• Roundworms
• Some are parasitic
Hookworms = drink blood of GI tract
Trichirella found in pig muscle
Filarial roundworms infect lymphatic
system
35. Phylum Annelida
• Segmented worms
Closed circulatory system
Five pair of hearts
Pharynx draws in food
Crops store food
Gizzard grinds food
Intestine absorbs nutrients
Rest is passed through the anus
36. Phylum Arthropoda
• Dominant animals wrt numbers
– exoskeleton made of chitin
– efficient gas exchange
– Well developed sensory system
– Well developed nervous system
– Well developed circulatory system
37.
38. Phylum Mollusca
• Shells of calcium carbonate
– mantle lays down the shell
• Open circulatory system( except for
cephalopods)
• Radula tongue made of chitin used to
scrape for food
• Bivalve named for number of shells
• About three-quarters of all living
species of molluscs are gastropods
39.
40. Phylum Echinodermata
• Water-vascular system for locomotion,
respiration and food acquisition
• Lack circulatory system
• Have regenerative capabilities
