Components of food Class-6th Chapter 2 Sciencekannupriya19
In this chapter we have discussed about components of food.different nutrients and their sources. We have also discussed about deficiency and diseases.
The document discusses locomotion and the skeletal and muscular systems that enable movement. It describes the three main types of joints - fixed, slightly movable, and freely movable - and provides examples like the ball and socket hip joint. The skeletal system is made up of bones and cartilage that protect organs and allow movement. Key bones include the skull, spine, ribs, limbs, and girdles. Muscles help movement by contracting and connecting to bones via tendons. Different animals like earthworms, snails, birds and fish have adapted skeletal/muscular systems suited to their environments and modes of locomotion.
The document discusses habitats and adaptations. It defines habitat as the surroundings where an organism lives, including biotic components (living things like plants and animals) and abiotic components (non-living things like air, water, soil, and temperature). Adaptations are specific features or behaviors that allow organisms to adjust to their habitat. Examples of adaptations in desert, mountain, grassland, and aquatic habitats are provided, such as a camel's humps for fat storage or long eyelashes to protect from sand. The document also discusses plant adaptations like creeping stems in grasslands and floating leaves in aquatic plants.
An atom is the smallest particle of an element that can exist. Atoms combine to form molecules, which are the basic units of compounds and some elements. Molecules can be represented by chemical formulas that show the number and type of atoms in the molecule, such as H2O for a water molecule containing two hydrogen atoms and one oxygen atom. Circles and spheres are also used to model atoms and molecules to aid in the study of their structures.
There are three main states of matter: solids, liquids, and gases. Solids have a fixed shape and volume, liquids have a fixed volume but take the shape of their container, and gases fill their container evenly. Matter can change between these three states through processes like melting, freezing, evaporation, and condensation. When a solute dissolves in a solvent, it forms a solution, and soluble and insoluble substances can be separated from solutions through methods like filtration, sedimentation, and decantation.
Matter exists in three states: solids, liquids, and gases. Solids have a definite shape and volume, while liquids take the shape of their container but have a definite volume. Gases fill their container completely and do not have a definite shape or volume. The particles that make up solids, liquids and gases, called molecules, behave differently in each state - in solids they are close together and don't move much, in liquids they are loosely tied and flow freely, and in gases they are far apart and move freely.

Muscles are connected to bones and help with movement. Examples are provided of common joints like the elbow, wrist, and knee.
The document discusses respiration in different animals. Mammals breathe in oxygen through their lungs which passes into their bloodstream, while fishes breathe through gills that absorb oxygen from water. Insects have a simple system of tracheae that transport gases, and amphibians breathe through gills as young but develop lungs when they mature on land. Respiration allows all animals to take in oxygen and release carbon dioxide through different specialized structures.
This document outlines the importance of a balanced diet and identifies the main nutrients found in different food groups. It discusses that a balanced diet contains the right amounts of energy sources like sugars and starches, proteins for growth and repair, vitamins, minerals, water, and roughage/fiber. Maintaining a balanced diet is important for overall health and preventing deficiency diseases.
This document discusses the classification and properties of pure substances and mixtures. It defines pure substances as elements or compounds that consist of a single type of matter, while mixtures contain two or more pure substances mixed together. Mixtures are classified as either homogeneous, containing substances mixed uniformly, or heterogeneous, containing visible particles that can be separated. The document also discusses various techniques for separating components of mixtures like evaporation, centrifugation, distillation and crystallization.
The document describes the structure and organization of the human body from cells to organ systems. It provides examples of each level of organization including cells forming tissues like muscle tissue, tissues forming organs like the heart, organs forming organ systems like the circulatory system, and organ systems coming together to form a complete organism.

Karl Marx was a German philosopher who lived from 1818 to 1883. He studied philosophy and economics in Berlin and married Jenny von Westphalen. Marx was a communist who co-wrote The Communist Manifesto with Friedrich Engels in 1848. Marx believed that society is divided between the wealthy owners and the working class, and that communism is a way for workers to gain equal rights and wealth. Though he predicted a communist revolution, one did not occur in Britain as he expected. Marx's ideas formed the basis of Marxism, which underlies the thinking of many political parties today.
Culturally Responsive Teaching & Critical PedagogyJay Henry
This document outlines an agenda for a summit on culturally responsive teaching and critical pedagogy. It includes an opening discussion on a poem and definition of culturally responsive teaching. Later sections discuss identity borderlands, dispositions of culturally responsive teachers, a pedagogy of opposition, and implications of culturally responsive teaching. The goal is for participants to leave with a conceptual map of these topics to analyze classrooms, staff, and trainings.
Asperger's syndrome is a developmental disability defined by impairments in social relationships, communication, and restrictive or repetitive behaviors. It is classified as an autism spectrum disorder. Treatment focuses on improving communication skills, obsessive behaviors, and physical clumsiness through therapies like social skills training, cognitive behavioral therapy, and language therapy. Parent education is also important. While its causes are unclear, Asperger's appears to have a genetic component and is not caused by parenting or emotional deprivation.
The document discusses the basic needs that all animals require to survive - food, air, water, and shelter. It explains that animals obtain these needs in different ways depending on whether they live on land, in water, or both. Food is obtained through eating plants, other animals, or both plants and animals. Air is breathed through lungs, gills, or skin. Water is obtained through drinking, the skin, or food. Shelter provides protection from predators, weather, and allows for resting and raising young. When animals are cared for by humans, their needs must still be met through proper housing, feeding, and care.
Scope Creep - Damned if I Do, Damned if I Don'tJustin Grammens
While everyone likes to share successes, let’s discuss the reality of software development. Projects are messy with lots of competing interests and challenges. One of these challenges that comes up often is scope creep. As software developers, we can be pulled in many different directions to not only help make the best product that we can but stay focused on the scope of what’s expected. Sometimes your job feels like: “Damned If I Do, Damned If I Don’t”. Let’s discuss the reality of the situation and some techniques and tools to help.
Session Outline:
Introduction: Some projects & experiences with scope creep I’ve had as a developer
Scope Creep: who are the guilty parties, what are the signs, why it happens, and when is it's most likely

The debris of the ‘last major merger’ is dynamically youngSérgio Sacani
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.
The binding of cosmological structures by massless topological defectsSérgio Sacani
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

Immersive Learning That Works: Research Grounding and Paths ForwardLeonel Morgado
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

The technology uses reclaimed CO₂ as the dyeing medium in a closed loop process. When pressurized, CO₂ becomes supercritical (SC-CO₂). In this state CO₂ has a very high solvent power, allowing the dye to dissolve easily.
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.
