Phylum Mollusca
This document summarizes the characteristics of the phylum Mollusca. It describes their soft unsegmented bodies, bilaterally symmetrical structure, and hard calcareous shells. It divides the body into a head, mantle, visceral mass, and foot. It provides details on their digestive, respiratory, circulatory, excretory, and nervous systems. It lists the six major mollusc classes and provides one example for each: Monoplacophora, Amphineura, Scaphopoda, Gastropoda, Pelecypoda/Bivalvia, and Cephalopoda.
Protochordates
Protochordates have two subphyla: urochordates and cephalochordates. Urochordates include sea squirts and related invertebrate groups, while cephalochordates are represented by amphioxus. Amphioxus is considered the most basal chordate and shares several anatomical similarities with the larval stage of lampreys, including a dorsal nerve cord, brain, myomeres, and filter feeding behavior, though amphioxus lacks a heart and organized kidney.
Mollusca general characters
The document provides an introduction and overview of the general characteristics of molluscs. It states that molluscs are soft-bodied animals that inhabit all habitats except air, have existed since the early Cambrian period, and are the second largest phylum of animals. The general characteristics described include having a triploblastic, bilaterally symmetrical body divisible into head, mantle, foot, and visceral mass, with shells sometimes present either internally or externally. Digestion and respiration occur through various organs like the radula, gills, lungs, and the circulatory system utilizes haemocyanin.

Animal-Kingdom pptx for all grades and age
Animals are made of cells that form tissues and organs. They obtain food by eating other organisms as herbivores, carnivores, or omnivores. Most animals reproduce sexually but some can reproduce asexually. There are three main types of food eaters: carnivores which eat meat, herbivores which eat plants, and omnivores which eat both plants and meat. Animals have either bilateral or radial symmetry and are divided into several phyla based on their characteristics. Some of the main phyla discussed include porifera, cnidaria, ctenophora, and platyhelminthes.
Protozoan taxonomy Animal diversity
Amoebae belong to the supergroup Amoebozoa. They form temporary extensions called pseudopodia for movement and feeding. Pseudopodia exist in different forms like lobopodia, filopodia, reticulopodia, and axopodia which are used for locomotion and ingesting food. Many amoebae lack protective structures, are found in freshwater environments, feed through phagocytosis, and reproduce asexually through binary fission.
protists_ppt.pdf
Protists are a diverse group of mostly single-celled eukaryotic organisms. They can obtain energy through photosynthesis like plants (e.g. Euglena), consume other organisms like animals (e.g. Amoeba), or decompose organic matter like fungi. Amoebas use pseudopods to move and engulf bacteria and algae as food. Euglenas have flagella and chloroplasts to move and perform photosynthesis, but also consume other microbes. Paramecia use cilia to propel themselves and sweep bacteria into their mouths for food. All three reproduce asexually through cell division.

Identify major groupings within the Lophotrochozoa and Ecdy gg g sozoa ; describe
distinguishing features among groups, where on Earth these organisms are typically found, and
how they make a living
Solution
Lophotrochozoa are a group or taxon of protostome animals. The taxon consists of 2 groups-
trochozoans and lophophorata. Trochozoans are characterized by the development of mouth
before anus in the embryo.They are worm like and produce trochophore larvae - larvae that have
2 bands of cilia around their middle. Lophophorata, on the other hand, are grouped by the
presence of lophophore characterized by a fan of ciliated tentacles surrounding their mouths.
These animals exhibit radial cleavage.
Lophotrochophora includes the following phyla
1. Phylum Ectoprocta:
These are mostly marine coelomates that use lophophore for feesing. They secrete and live in
zoecium (chitinous chamber).
2. Phylum platyhelminthes
These are mostly parasitic acoelomates. Some may live as scavengers or commensals. The are
flat and ribbon-shaped. They have an incomplete gut, no circulatory system, and a simple
nervous system. Their excretory system has small tubules lined with ciliated flame cells. They
are hermaphrodites.
3. Phylum Rotifera
These are small aquatic pseudocoelomate animals. They are mostly free living and a few are
paraitic. They have a ciliated food gathering organ at the tip of the head known as corona. They
have jaws in the pharynx and their digestive system has separate mouth and anus. They have
rudimentary circulatory system and they have separate sexes.
4. Phylum Annelida
They are segmented coelomates with a closed circulatory system. Their excretory system
includes nephrida. They have a digestive system with separate mouth and anus. Gas exchange is
through skin.They have setae. They are found in both terrestrial and aquatic habitats. They can
be parasites, carnivores, predators or scavengers.
5. Phylum Nemertea
They are partially coelomate and partially acoelomate animals. They are free living and possess
proboscis - a long muscular tube covered by a sheath to capture prey. They have a complete
digestive system, a simple nervous system, and a closed circulatory system.
6. Phylum Phoronida:
They are coelomate and marine. They use lophophore for feeding. They have a U-shaped gut and
they secrete and live in a chitinous tube.
7. Phylum Brachipoda:
They are characterized by the presence of 2 calcified shells.
Ecdysozoa also belons to the group of protostome animals characterized by a three layered
cuticle which is periodically molted,a process known as ecdysis. They lack locomotary cilia.
They produce amoeboid sperm. Their embryos donot undergo spiral cleavage unlike other
protostomes.
The group includes
Phylum arthropoda
The phylum includes invertebrate animals with an exoskeleton. They have jointed limbs and
their cuticle is made of chitin. They are segmented with an open circulatory system and a ladder-
like nervous system They are found in both a.

The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

Deep Software Variability and Frictionless Reproducibility
Deep Software Variability and Frictionless ReproducibilityUniversity of Rennes, INSA Rennes, Inria/IRISA, CNRS
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.
