AP Bio Ch. 6.3 - 6.4 organelles
The document summarizes key organelles in eukaryotic cells, including the nucleus, ribosomes, and components of the endomembrane system. The nucleus houses DNA and directs gene expression. There are two types of ribosomes - bound to the ER to produce membrane-bound proteins, and free-floating to make other proteins. The endomembrane system, including the ER, Golgi apparatus, lysosomes, and vacuoles, works together to modify and transport molecules like proteins throughout the cell.
The organization of living things
Multicellular organisms have several advantages over unicellular organisms including larger size allowing them to avoid more predators, longer lifespans not limited by single cells, and specialization where each cell type performs a specific job making the organism more efficient. The structure of organisms is organized into hierarchical levels from cells to tissues to organs to organ systems with each level working together to carry out life processes. Structure and function are also related in organisms, where the arrangement of parts enables them to perform their necessary jobs.

Active transport
Cell membranes use pumps and transport proteins to actively move molecules against their concentration gradient, requiring energy in the form of ATP. Endocytosis and exocytosis allow cells to transport larger particles and molecules into and out of the cell, respectively. Endocytosis involves invagination of the cell membrane to form vesicles that deliver their contents within the cell, while exocytosis uses vesicles to export cellular contents outside the cell. Both processes are energy-requiring forms of active transport.

Habitat changes by animals
Beavers change habitats by cutting down trees with their teeth to build dams and houses, which form ponds. Their dams help forests during floods and drought by regulating water levels. People also change habitats by building structures and cutting down trees, and by hunting animals for their fur, which can endanger some species. If endangered animals like rhinoceros, pandas and turtles are not protected, they may go extinct, meaning their kind will disappear from Earth forever, as happened to creatures like saber-tooth tigers, mammoths and dinosaurs.
Habitat changes by nature activity
Habitat changes occur naturally over time. Human activity can also impact habitats and alter them from their natural state. Both natural changes and human impacts need to be considered for protecting wildlife and biodiversity.
How do you know if something is a
Living things need to survive and have certain needs to stay alive, such as animals needing food, water, shelter and space while plants need sunlight, water and nutrients from the soil to survive and grow. Non-living things do not have needs for survival.
Habitat
Habitat is the natural home or environment where animals live. Grassland is a type of habitat that is warm and covered in grass, providing a home for various animal species. Different habitats include grasslands and other places where animals find shelter, food, and meet other needs.
Fossils
Fossils are remains of living things from the past that can tell us about changes to habitats over time. They provide evidence that habitats like deserts were once underwater, showing that droughts or other events transformed water environments into deserts. Fossils thus help reveal how habitats have changed since ancient times.
Fossils activity
Fossils are the preserved remains or traces of ancient organisms. Students will learn about fossils by examining real examples and discussing how and why organisms from the past can become fossilized. They will also think about how fossils provide evidence about past life on Earth and how organisms have changed over time.

Little Andy wanted to make lemon juice for her family but couldn't find any sugar. She went through the scientific method to solve this problem. First, she observed there was no sugar and asked what could make the juice sweet instead. Andy then gathered alternatives like honey, jam, and chocolate. She hypothesized that honey might work and tested this in an experiment. The lemon juice with honey tasted good, so Andy recorded her results and concluded that honey can be used when sugar is unavailable.

Ch.12.less.12.how does light travel and interact with matter
This document discusses how light travels and interacts with matter. It explains that light travels from the sun to earth at a distance of 90 million miles. Light is made up of electric and magnetic waves, and travels faster in a vacuum than in other materials. The document defines transparent, translucent, and opaque materials and how they interact with light. It describes the formation of shadows and the law of reflection. Refraction of light is explained when light passes from one medium to another. The document also discusses the visible spectrum and how different colors of light have different wavelengths.
How does light travel and interact
Light is made up of electromagnetic waves that can travel through vacuum at high speeds without a medium. When light hits an object, it can be absorbed, reflected, or pass through. Transparent materials allow most light to pass through, translucent materials allow some light, and opaque materials do not allow any light to pass through. Light travels in a straight line and forms shadows when it hits opaque objects, with the shadow position depending on the light source position.
Dichotomous key
Classification systems are important because they organize items into groups based on common characteristics. This makes it easier to find and identify things. For example, music stores organize their CDs by music type and artist. Shoe stores also classify shoes into groups like boys, girls, men and women to make shopping easier. Scientists use classification to group organisms based on shared traits. A dichotomous key is a classification tool that uses yes/no questions to identify organisms by separating them into increasingly specific groups. The document provides examples of how a dichotomous key can be used to classify insects and animals into groups based on characteristics like number of legs, wings, and tails.
How do the parts of an ecosystem interact

What are the building blocks of matter
This document defines key chemistry terms including atoms, molecules, elements, compounds, mixtures, and solutions. Atoms are the smallest unit of matter that cannot be divided further. Molecules are formed when two or more atoms combine chemically. Matter is made up of elements, compounds, mixtures, and solutions. Elements are made of the same type of atom, compounds contain two or more types of atoms bonded together with a specific chemical formula. Mixtures contain elements or compounds that are not chemically bonded. Solutions occur when a solute dissolves evenly throughout a solvent.
How do weathering and erosion shape the land 1
Weathering is the process by which rocks and other materials break down. There are two main types of weathering: physical and chemical. Physical weathering involves changes to the physical properties of rocks through processes like temperature changes, plant and animal activity, and abrasion by water or wind. Chemical weathering changes the chemical composition of rocks through reactions with substances like water, acid rain, and oxygen. Erosion is the process by which weathered materials are transported by forces like water, wind, ice, and gravity. Erosion and weathering work together over time to shape and change the Earth's surface landscape.
How does light travel and interact with matter
Light is made up of electric and magnetic waves that travel in a straight line at very high speeds, such as 90 million miles from the sun to earth. Light can pass through transparent materials like glass that allow most light through, is partially blocked by translucent materials like wax paper, and is completely blocked by opaque materials like metal that form shadows. The position of shadows depends on the position of the light source.
How does electricity affect our life
Electricity affects our lives in many ways. It is a form of energy resulting from the movement of electric charges like electrons. Electricity flows through conductors like metals in a closed circuit that includes a power source, wires, and a load. Common examples of circuits include those powering lights and appliances. Electricity is controlled through the use of switches, which open or close circuits to turn power flow on and off. Insulators like plastic are used to safely handle wires carrying electric current. Electromagnets demonstrate how electric currents can generate magnetic fields.
How does electricity affect our life
Electricity affects our lives in many ways. It is the flow of electric charges through materials. Electric charges can be positive or negative, and opposite charges attract while like charges repel. Static electricity builds up when charges accumulate on objects. Electric current flows through circuits that contain a power source, conductor, and load. Circuits can be open or closed, and materials are classified as conductors, which allow current to flow, or insulators, which do not.
What are the properties of minerals and rocks
This document discusses the rock cycle and the three main types of rocks: sedimentary, igneous, and metamorphic. Sedimentary rocks are formed through the compression of materials like sand and shells. Igneous rocks form when magma cools, either underground to form intrusive igneous rocks like granite or above ground to form extrusive igneous rocks like basalt. Metamorphic rocks are formed from existing rocks that undergo heat or pressure and are transformed, such as limestone becoming marble. The rock cycle shows how rocks continuously change between these three types through geological processes like weathering, erosion, deposition, and metamorphism.
How does electricity affect our life1
Electricity affects our lives in many ways. It is the flow of electric charges through a circuit. A circuit must be closed and contain a power source, such as a battery, connected to a load like a light bulb through a conducting material path. Circuits can be opened using a switch or by breaking the conducting path. Materials are classified as conductors, which allow electric current to flow, or insulators, which do not. Common conductors are metals, while plastics and rubber serve as insulators.
How are living things similar and different
This document provides information about classifying living things. It explains that classification involves grouping organisms based on similar characteristics. The modern 7-level classification system consists of Kingdom, Phylum, Class, Order, Family, Genus, and Species. The document then describes how the animal kingdom is divided into vertebrates and invertebrates. It provides examples of different types of vertebrates and invertebrates and explains some of their distinguishing characteristics.
Mammals and birds.ppt
The document describes the characteristics of different groups of vertebrates including mammals, birds, fish, reptiles and amphibians. It notes that mammals give birth to babies and feed them milk from their lungs. Birds have wings, feathers, lay eggs and have lungs. It then provides three puzzles asking to identify an animal from its description and which group it belongs to. The puzzles are identified as whales belonging to the mammal group, penguins belonging to the bird group, and bats belonging to the mammal group.
Vertebrates classification
The document describes five categories of animals - mammals, birds, amphibians, fish, and reptiles. It provides 3 key distinguishing characteristics for each category:
Mammals: give birth to live young, feed babies milk, have fur and lungs. Birds: have feathers and wings, have lungs, lay eggs. Amphibians: lay eggs in water, have moist skin, young live in water as adults live on land. Fish: have scales, gills to breathe, lay eggs and live entirely in water. Reptiles: have scales and dry skin, lungs, lay leathery eggs.
Vertebrates and invertebrates
Animals are grouped into two categories: vertebrates, which have a vertebral column or backbone, and include animals like camels, crocodiles, ducks, elephants, giraffes, frogs, lions, rats, snakes, and turtles. The second group is invertebrates, which do not have a backbone and includes animals such as bees, ants, cockroaches, house flies, prawns, jellyfish, crabs, butterflies, octopuses, snails, worms, and starfish.
Classification of living things
This document discusses classification of living things. It explains that classification is the grouping of organisms according to similar characteristics. The modern 7-level classification system was developed by Linnaeus and consists of kingdom, phylum, class, order, family, genus, and species, with species being the smallest group. An example of human classification using this system is provided.
The solar system
The document discusses the solar system and compares Earth to other objects within it. It explains that the solar system consists of the Sun and objects that orbit around it, including planets and moons. The planets are divided into rocky terrestrial planets like Earth and gas giants like Jupiter. Earth is the third planet from the Sun and is unique for hosting life and having 70% of its surface covered in water. The document provides details about each of the eight planets in our solar system, including their order from the Sun and distinguishing characteristics.

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.
Cytokines and their role in immune regulation.pptx
This presentation covers the content and information on "Cytokines " and their role in immune regulation .
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.
Phenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

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.

Ch.1.less.1. what are the structures of plant and animals cells
- 1. Chapter 1: Lesson 1: What are the structures of plant and animals cells? Grade 5
- 2. Any living thing is called Living Organism
- 4. What is our school made of?
- 5. Bricks (Are the smallest building unit that make up our school)
- 6. Also, Our bodies are made of: Systems Organs TissuesCells Which is made of Which is made of Which is made of (The smallest building unit of our body)
- 7. What do cells do? Cells help us: 1) Grow 2) Breathe 3) Move 4) Reproduce (make more of its kind) 5) Excrete (remove wastes from their bodies) 6) Respond to stimulus (feel the weather changes) 7) Feed
- 8. Smallest unit of living things that can carry out the basic processes of life. Cells
- 9. Cells Unicellular (Organisms made of only one cell) Multicellular (Organisms made of many cells)
- 10. Plant Cell organelle functions 1) Cell Wall - Stiff structure outside the cell membrane. - It provides the cell with strength and extra support.
- 11. 2) Cell membrane - Controls what materials enter the cell and what materials leave the cell. (It’s like the gate of the cell)
- 12. 3) Cytoplasm - Gel like liquid mostly made of water. - It fills the area between the cell membrane and nucleus (organelles float in it). (It’s clear, thick & jelly like substance)
- 13. 4) Nucleus - Controls all the cell functions (the brain of the cell). (It acts like our brain that control every job we do)
- 14. 5) Vacuole - 1 large central vacuole used for storing excess water and providing extra support to the plant. (It acts like store house that stores water, food & excess wastes of the cell) (i.e: It’s like our lunch box)
- 15. 6) Mitochondria - Oval, membrane covered organelle that breaks down food to give energy to the cell (power plant). (It acts like the power house or power factory that gives energy to the cell)
- 16. 7) Chloroplast - A green structure where energy from the sunlight is used to make the plants food. (Contains chlorophyll)
- 18. Animal Cell organelle functions 1) Cell membrane - Give the cell its shape. - Controls what materials enter the cell and what materials leave the cell.
- 19. 2) Cytoplasm - Gel like liquid mostly made of water. - It fills the area between the cell membrane and nucleus (organelles float in it). - Some of the life processes take place in it.
- 20. 3) Nucleus - Controls all the cell functions (the brain of the cell).
- 21. 4) Vacuole - A membrane covered structure used for storage (stores food, water and wastes). - Some animal cells have many small vacuoles and some do not have vacuoles.
- 22. 5) Mitochondria - Oval, membrane covered organelle that breaks down food to give energy to the cell (power plant). - Animal cells that need more energy (ex. muscle cells) have many mitochondria.
