You’d think that a carrot is a carrot is a carrot, but that’s just not the case – some carrots are just carrots, and others are also intergalactic superheroes. And we’ve got a series of amazing fruits and vegetables here to prove it.In truth, there is quite a variety of reasons for which a fruit or vegetable can grow into weird shapes. The most common is damage/scar tissue. If some part of the fruit or vegetable is scarred, especially during its earliest growing stages, this can slow the growth in that area and cause it to deform the rest of the plant.
Plants have families with different parts that each have important jobs. Flowers attract insects and birds to help make seeds, stems carry water and nutrients, roots absorb water and nutrients from the soil, and leaves make food through photosynthesis. Photosynthesis uses carbon dioxide, sunlight, and water to make food and release oxygen. Plant leaves have structures like the cuticle, epidermis, chloroplasts, and stomata that help them survive. Plants can be classified by their structure, root type, stem type, whether they produce seeds or spores, and if they are edible.
Cako, a little monkey, wants to eat some nuts but can't reach them. He uses the scientific method to solve this problem. He observes the nuts in a cylinder, asks how to get them out, gathers information by looking in Anne's book, hypothesizes that water will make the nuts float, experiments by pouring water in the cylinder, records that his hypothesis was correct, and concludes that water makes nuts float like a boat. The story demonstrates the seven steps of the scientific method: observe a problem, ask a question, gather information, make a hypothesis, experiment, record results, and draw a conclusion.
This document outlines lab safety rules but provides no details about the specific rules. It lists numbers from 1 to 87 which seem to correspond to individual rules but the rules themselves are not stated. The document gives no context or explanation for the purpose of the lab safety rules.
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.

How do plants survive in the environment?safa-medaney
Plants survive in their environment through various adaptations and responses to stimuli. They respond to light by bending towards it using chemicals in their shoots. They respond to gravity by growing roots downward and stems upward. They respond to water by growing roots toward its source, like mangrove trees. Plants adapt to their environments through structures like cacti using thick waxy covers and spines to conserve water in dry deserts or trees growing large leaves to catch sunlight in shaded forests. They also go dormant during extreme weather, stopping growth and photosynthesis until conditions improve.
This document introduces various lab tools used in science class including safety goggles, test tubes, test tube brushes, test tube holders, test tube racks, spatulas, microscopes, beakers, funnels, droppers, graduated cylinders, digital balances, thermometers, stop watches, hand lenses, conical flasks, measuring tapes, and compasses. Each tool is described briefly in terms of its purpose or how it is used.
Plants need sunlight, air, water, and nutrients from the soil to grow. The main parts of a plant are the roots, stem, leaves, and flowers. The roots hold the plant in place and take in water and nutrients from the soil. The stem supports the plant and transports water and nutrients between the roots and leaves. Leaves use sunlight, air, water, and nutrients to photosynthesize and produce food for the plant.
Seed plants reproduce through seeds, which contain an embryo and stored food inside protective seed coats. Seeds come in many shapes and sizes depending on the plant. Pine trees reproduce through male cones that produce pollen and larger female cones that receive pollen and produce seeds. Flowers also help in reproduction, with male stamen producing pollen and female pistils receiving pollen. Pollination occurs when pollen is transferred, allowing fertilization and the production of seeds inside fruits. For seeds to germinate and grow into new plants, they need favorable conditions like water, warmth and light.

This document provides an overview of plant and animal cell structures and their functions. It explains that cells are the smallest and basic unit of living things that can carry out life processes. Plant cells have additional structures like cell walls, chloroplasts and central vacuoles that store water and food. Animal cells do not have cell walls or chloroplasts. Both plant and animal cells contain a cell membrane, cytoplasm, nucleus, mitochondria and vacuoles. The cell membrane controls what enters and exits the cell. The nucleus controls all cell functions. Mitochondria produce energy and vacuoles store waste and food.

The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise boosts blood flow and levels of serotonin and endorphins which elevate mood and may help prevent mental illness.
The document discusses conductors and insulators in electrical circuits. It states that materials fall into three categories: insulators, which do not allow electric current to pass through; conductors, which do allow current to pass through, such as metals like copper and aluminum; and circuits, which provide an unbroken path for electric current to flow through conductive materials. Insulators are used to cover electric wires to protect from electric shock. Switches are used to open and close circuits to control current flow.
Ch.12.less.2.what are the properties of sound -safa-medaney
This document discusses the properties of sound. It defines sound as a type of energy that moves through matter in longitudinal waves of vibration. It describes how sound travels faster through solids than gases due to the closer packing of particles. Frequency is defined as the number of times a particle vibrates per second and is measured in Hertz. Pitch and frequency are related, but not the same - pitch is how our ears perceive sound based on the number of peaks in the vibrations. Amplitude refers to the density of particles during compression and rarefaction and is measured in decibels.
Ch.12.less.12.how does light travel and interact with mattersafa-medaney
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.
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.
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.

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 1safa-medaney
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.

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.
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 rockssafa-medaney
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.
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 differentsafa-medaney
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.
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.
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.
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.
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.
Nucleophilic Addition of carbonyl compounds.pptxSSR02
Nucleophilic addition is the most important reaction of carbonyls. Not just aldehydes and ketones, but also carboxylic acid derivatives in general.
Carbonyls undergo addition reactions with a large range of nucleophiles.
Comparing the relative basicity of the nucleophile and the product is extremely helpful in determining how reversible the addition reaction is. Reactions with Grignards and hydrides are irreversible. Reactions with weak bases like halides and carboxylates generally don’t happen.
Electronic effects (inductive effects, electron donation) have a large impact on reactivity.
Large groups adjacent to the carbonyl will slow the rate of reaction.
Neutral nucleophiles can also add to carbonyls, although their additions are generally slower and more reversible. Acid catalysis is sometimes employed to increase the rate of addition.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...Sérgio Sacani
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.

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.

Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
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.
Current Ms word generated power point presentation covers major details about the micronuclei test. It's significance and assays to conduct it. It is used to detect the micronuclei formation inside the cells of nearly every multicellular organism. It's formation takes place during chromosomal sepration at metaphase.
