Diffusion and osmosis homework powerpointclairebloom
Diffusion is the movement of molecules from an area of high concentration to low concentration until evenly spread. All living cells rely on diffusion to obtain raw materials and remove waste through cell membranes. Osmosis is a type of diffusion where water specifically moves across a selectively permeable membrane from high to low concentration to balance water levels on both sides of the membrane. This movement can cause cells to shrink or burst depending on their environment.
The document discusses the parts of a plant and how plants grow from seeds. It notes that roots take in water and nutrients from the soil, stems hold up the plant and move water and nutrients, and leaves use sunlight, air, water and nutrients to make food. Flowers make fruits containing seeds. Seeds are scattered by planting, animals, water and wind and can germinate into seedlings when they have sunlight, air, water and nutrients.
The document discusses astronomy and the scientific study of celestial objects. It provides information on stars, galaxies, and the formation and components of the solar system. Specifically, it notes that astronomy is the study of matter in outer space, including the positions, dimensions, distribution, motion, composition, energy, and evolution of celestial bodies.

The document discusses the motion of the Earth and how it causes day and night as well as apparent motion of the sun. It explains that the Earth rotates on its axis every 24 hours, which causes one side of the Earth to face the sun while the other side faces away, creating day and night. It also discusses how the Earth revolves around the sun over the course of 365 days.
All living things go through life cycles that involve different stages of development. The butterfly's life cycle has four main stages: egg, caterpillar, pupa, and adult butterfly. As a caterpillar, it eats leaves and grows quickly before forming a pupa and undergoing transformation inside until emerging as a young butterfly and finally a mature adult butterfly that can lay new eggs.

Simple machines make work easier by changing the amount or direction of force needed. There are six basic types of simple machines: the lever, pulley, wheel and axle, inclined plane, screw, and wedge. Compound machines combine two or more simple machines; examples include scissors, bicycles, and wheelbarrows.
This document discusses how forces like pushes and pulls cause motion by either moving things away (push) or bringing them closer (pull). It defines any push or pull that moves an object as a force. The document encourages the reader to have a wonderful day.
The document discusses the formation and composition of soil. It explains that soil is formed over long periods of time through the weathering and breakdown of rocks and the decomposition of dead plants and animals. The soil is made up of weathered rocks, humus from decomposed materials, and minerals. It has distinct layers with varying properties including the topsoil, subsoil, and bedrock below. Different types of soil like sand, silt, and clay are determined by the size of particles. Loam is an ideal soil made of a mixture of these. The document emphasizes the importance of protecting soil as a vital natural resource.
This document discusses different types of water resources and how water is treated and distributed for human use. It explains that there are two main types of water - fresh water found in rivers, lakes, glaciers etc. and salt water found in oceans. It then outlines several key steps in treating water from rivers and lakes, such as allowing solids to settle, filtering through layers of sand and gravel, adding chemicals to kill harmful organisms, and pumping the clean water for distribution.
Natural disasters and diseases can change environments and affect living organisms. Floods occur when heavy rain falls in a short period, covering land with water, while droughts are long periods without rain that can dry up rivers and lakes, increasing wildfire risks that damage plant and animal habitats. Diseases from mold, bacteria, and mildew also easily spread in environments and harm living things, with one infected tree having the potential to destroy an entire forest.
Plants need five things to survive and grow: oxygen from the air, water, nutrients found in soil, space to grow freely, and sunlight. Fruits were once living parts of plants but become non-living when picked after ripening.
Organisms adapt traits that help them survive in their environments. Some examples of adaptations include camouflage, mimicry, nocturnal behavior, hibernation, and migration. Camouflage allows animals to blend into their surroundings and hide from predators or to ambush prey. Mimicry enables some animals to resemble other organisms for protection. Nocturnal habits, hibernation, and migration are ways animals adapt to changes or shortages in their environments like weather changes or lack of food sources. Plants also exhibit adaptations like deep roots that help them survive in difficult conditions.
Liquids and gases take the shape of their container, unlike solids which do not. Volume is defined as the space occupied by matter, and can be measured using tools like measuring cups. Common units for measuring volume include liters and milliliters.
The document compares different ecosystems by describing their climates and key characteristics. Tropical rainforests have hot, wet climates all year and contain the greatest diversity of plants and animals. Temperate forests' climates change with warm summers and cold winters, and they receive less rain than rainforests. Wetlands are covered in water most of the year, found along rivers and coasts, and help absorb flood waters and cleanse dirty water. Oceans are the largest ecosystem and most living things inhabit the sunlit, shallow areas near the surface.
Food chains and food webs show how energy passes from one organism to another as they eat each other. A food chain tracks the flow of energy starting with a plant that gets its energy from the sun, then to an animal that eats the plant, then another animal that eats the first animal. A food web is more complex, showing that organisms can be part of multiple food chains as some animals eat different plants and other animals.
This document discusses three categories of animals based on their diets: herbivores, which eat only plants; carnivores, which eat only meat; and omnivores, which eat both plants and meat. Herbivores include deer, rabbits, elephants, turtles, monkeys and giraffes. Carnivores include lions, crocodiles, snakes and eagles. Omnivores include bears, raccoons, pigs, and humans.
An ecosystem is a place where living and non-living things interact, and can exist in various environments from wet to dry and small to large. In an ecosystem, living things depend on each other and non-living things like water, soil and sunlight. Producers like plants make their own food through photosynthesis, while consumers like animals obtain food by eating other organisms, and decomposers like worms break down dead plants and animals and return nutrients to the soil.
This document discusses habitats and the different animals that live in each one. It explains that a habitat provides all the needs for animals to survive, including food, water and shelter. It then identifies the five main habitats as ocean, forest, desert, grasslands, and Antarctica, and provides some example animals for each one. The habitats differ in their characteristics such as being wet or dry, hot or cold, containing trees, grass or snow.

Compositions of iron-meteorite parent bodies constrainthe structure of the pr...Sérgio Sacani
Magmatic iron-meteorite parent bodies are the earliest planetesimals in the Solar System,and they preserve information about conditions and planet-forming processes in thesolar nebula. In this study, we include comprehensive elemental compositions andfractional-crystallization modeling for iron meteorites from the cores of five differenti-ated asteroids from the inner Solar System. Together with previous results of metalliccores from the outer Solar System, we conclude that asteroidal cores from the outerSolar System have smaller sizes, elevated siderophile-element abundances, and simplercrystallization processes than those from the inner Solar System. These differences arerelated to the formation locations of the parent asteroids because the solar protoplane-tary disk varied in redox conditions, elemental distributions, and dynamics at differentheliocentric distances. Using highly siderophile-element data from iron meteorites, wereconstruct the distribution of calcium-aluminum-rich inclusions (CAIs) across theprotoplanetary disk within the first million years of Solar-System history. CAIs, the firstsolids to condense in the Solar System, formed close to the Sun. They were, however,concentrated within the outer disk and depleted within the inner disk. Future modelsof the structure and evolution of the protoplanetary disk should account for this dis-tribution pattern of CAIs.

Mechanics:- Simple and Compound PendulumPravinHudge1
a compound pendulum is a physical system with a more complex structure than a simple pendulum, incorporating its mass distribution and dimensions into its oscillatory motion around a fixed axis. Understanding its dynamics involves principles of rotational mechanics and the interplay between gravitational potential energy and kinetic energy. Compound pendulums are used in various scientific and engineering applications, such as seismology for measuring earthquakes, in clocks to maintain accurate timekeeping, and in mechanical systems to study oscillatory motion dynamics.
Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...Sérgio Sacani
Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement.

SDSS1335+0728: The awakening of a ∼ 106M⊙ black hole⋆Sérgio Sacani
Context. The early-type galaxy SDSS J133519.91+072807.4 (hereafter SDSS1335+0728), which had exhibited no prior optical variations during the preceding two decades, began showing significant nuclear variability in the Zwicky Transient Facility (ZTF) alert stream from December 2019 (as ZTF19acnskyy). This variability behaviour, coupled with the host-galaxy properties, suggests that SDSS1335+0728 hosts a ∼ 106M⊙ black hole (BH) that is currently in the process of ‘turning on’. Aims. We present a multi-wavelength photometric analysis and spectroscopic follow-up performed with the aim of better understanding the origin of the nuclear variations detected in SDSS1335+0728. Methods. We used archival photometry (from WISE, 2MASS, SDSS, GALEX, eROSITA) and spectroscopic data (from SDSS and LAMOST) to study the state of SDSS1335+0728 prior to December 2019, and new observations from Swift, SOAR/Goodman, VLT/X-shooter, and Keck/LRIS taken after its turn-on to characterise its current state. We analysed the variability of SDSS1335+0728 in the X-ray/UV/optical/mid-infrared range, modelled its spectral energy distribution prior to and after December 2019, and studied the evolution of its UV/optical spectra. Results. From our multi-wavelength photometric analysis, we find that: (a) since 2021, the UV flux (from Swift/UVOT observations) is four times brighter than the flux reported by GALEX in 2004; (b) since June 2022, the mid-infrared flux has risen more than two times, and the W1−W2 WISE colour has become redder; and (c) since February 2024, the source has begun showing X-ray emission. From our spectroscopic follow-up, we see that (i) the narrow emission line ratios are now consistent with a more energetic ionising continuum; (ii) broad emission lines are not detected; and (iii) the [OIII] line increased its flux ∼ 3.6 years after the first ZTF alert, which implies a relatively compact narrow-line-emitting region. Conclusions. We conclude that the variations observed in SDSS1335+0728 could be either explained by a ∼ 106M⊙ AGN that is just turning on or by an exotic tidal disruption event (TDE). If the former is true, SDSS1335+0728 is one of the strongest cases of an AGNobserved in the process of activating. If the latter were found to be the case, it would correspond to the longest and faintest TDE ever observed (or another class of still unknown nuclear transient). Future observations of SDSS1335+0728 are crucial to further understand its behaviour. Key words. galaxies: active– accretion, accretion discs– galaxies: individual: SDSS J133519.91+072807.4
Evidence of Jet Activity from the Secondary Black Hole in the OJ 287 Binary S...Sérgio Sacani
Wereport the study of a huge optical intraday flare on 2021 November 12 at 2 a.m. UT in the blazar OJ287. In the binary black hole model, it is associated with an impact of the secondary black hole on the accretion disk of the primary. Our multifrequency observing campaign was set up to search for such a signature of the impact based on a prediction made 8 yr earlier. The first I-band results of the flare have already been reported by Kishore et al. (2024). Here we combine these data with our monitoring in the R-band. There is a big change in the R–I spectral index by 1.0 ±0.1 between the normal background and the flare, suggesting a new component of radiation. The polarization variation during the rise of the flare suggests the same. The limits on the source size place it most reasonably in the jet of the secondary BH. We then ask why we have not seen this phenomenon before. We show that OJ287 was never before observed with sufficient sensitivity on the night when the flare should have happened according to the binary model. We also study the probability that this flare is just an oversized example of intraday variability using the Krakow data set of intense monitoring between 2015 and 2023. We find that the occurrence of a flare of this size and rapidity is unlikely. In machine-readable Tables 1 and 2, we give the full orbit-linked historical light curve of OJ287 as well as the dense monitoring sample of Krakow.
