Snails can live in gardens, under water, or underground depending on temperature, with optimal temperatures between 69-80 degrees Fahrenheit. They have a variety of internal organs and feelers to help them navigate, and move using muscles in their foot. Additionally, sea snails are a type of snail, there are over 30,000 known species of snails worldwide, and snails have existed for over 600 million years, making them one of the earliest known animal life forms.
Frogs are amphibians with webbed toes that make them great swimmers, strong hind legs for jumping, and long sticky tongues for catching insects. They also have smooth moist skin and bulging eyes.
Animals have different features that help them survive - reptiles shed scales, mammals produce milk to feed babies, birds have wings to fly, fish have fins to swim, snakes have forked tongues and frogs have sticky tongues to catch prey.
Bats are mammals that give birth to live young, have fur and nurse their young. While they have wings like birds, bats are distinguished in that they are warm-blooded and use echolocation to navigate and hunt. Bats use echolocation by emitting sounds and listening to the echoes to identify objects, determine their size, shape and texture.
The document discusses the lifecycle of frogs. It begins in the water, with female frogs laying eggs protected by jelly. The eggs hatch into tadpoles that breathe with gills and eat as they grow. Tadpoles eventually grow legs and lose their tails, becoming froglets that can breathe on land. Finally, the froglets mature into adult frogs that live on land and have fully developed lungs and limbs.

Snakes are reptiles found on every continent except Antarctica. They have no legs and no eyelids. There are over 3,400 snake species that vary greatly in size, from 10 cm to 9 meters long. Snakes use their forked tongue to smell and track prey. Some snakes can see infrared radiation to detect warm-blooded animals. Snakes are covered in scales and shed their skin periodically. They are carnivorous, eating small animals, birds, eggs or insects. Venomous snakes use venom to paralyze prey, while constrictors kill by coiling around their victim. In colder climates, snakes brumate or become inactive during winter instead of hibernating.

this ppt is about super senses of animals, birds and insects. Like five senses of humans, many other animals do have different senses. these special senses are called super senses.
The document discusses animals' super senses like smell, sight, hearing, and sleep patterns. It provides examples of how ants, silkworms, dogs, and mosquitoes use their enhanced sense of smell. Birds like eagles have excellent eyesight to spot prey from far away. Snakes use vibrations through the ground to detect objects. Some animals use different sounds to warn of dangers or communicate. The document also lists sleep times of various animals and mentions national parks in India that protect endangered animals like tigers, lions, and rhinos.
This document discusses the unique physical characteristics of various animal and plant species that help them survive in their environments. It provides examples of six animal species - bats, geckos, monitor lizards, camels, owls, and archerfish - and their special adaptations such as echolocation in bats, sticky pads on geckos' feet, humps for fat storage in camels, and water shooting in archerfish. It also briefly describes the simple body structure of coral as a stationary sea animal.
Despite their growing urban populations, seagulls are considered endangered in the UK. Seagulls are monogamous and mate for life, returning to the same nesting sites every year. They have several adaptations that help them thrive, including the ability to excrete salt via glands above their eyes after drinking seawater, sharing incubation duties, and possessing superior night vision compared to humans.
The platypus uses its sensitive snout to detect tiny movements of prey in rivers and streams, as its skin covers its eyes and ears when it dives. It is one of few mammals that lays eggs. Wallabies are marsupials where tiny babies live in their mother's pouch to feed and grow until around 10 months old. Dolphins are powerful swimmers that can reach speeds over 20 mph with their streamlined shape, strong tail flukes, and steering flippers, though they usually swim at 5 mph. Bats have built-in radar called echolocation that helps them fly and hunt in darkness by emitting high-pitched noises.
The coolest new species of the 21st centuryJulianne Cox
The document discusses 13 of the coolest new species discovered in the 21st century. These include:
1. A cockroach-zombifying wasp named the Ampulex dementor after the soul-sucking creatures in Harry Potter.
2. A small spider from Morocco named the cartwheeling spider that can jump 6.6 feet per second to escape predators.
3. A fish discovered off the coast of Indonesia that resembles the Star Wars character Greedo, leading to it being named Peckoltia greedoi.
4. Two new species of colorful freshwater crabs from Indonesia called Geosesarma dennerle and Geosesarma hagen.
Lizards make up 60% of reptiles and occur on all continents except Antarctica. They are typically identified by their elongated body and four limbs with a long tail. Lizards vary tremendously in size, from the smallest gecko at 1.5 inches to the largest Komodo dragon at 10 feet. Lizards tails serve different purposes depending on the species, such as providing extra grip for chameleons or breaking off as a defense mechanism to escape predators for other species. Monitor lizards are considered the most advanced lizards as the direct ancestors of snakes, shown through traits like their long, serpentine body and forked tongue.
Animals are fascinating creatures that have captivated humans since the dawn of time. While we know a lot about some species, others remain elusive and mysterious
The document describes 24 unusual animal species from around the world, including the blanket octopus that can spread its tentacles like a blanket, the blobfish that floats lazily in the deep sea, and the hairy crab that filters pollution from water using its setae "hairs." It also mentions the leafy sea dragon that camouflages itself to look like seaweed, the axolotl salamander that never undergoes metamorphosis, and the tarsier, the lone surviving member of its primate family.
The document lists 10 exotic animals and provides 1-2 sentences describing each one. It includes: 1) The Etruscan pygmy shrew, the smallest known mammal. 2) The squirrel monkey, the most nervous and cuddly primate. 3) The tamandua, a lesser anteater found in South America. 4) The white lion, a vulnerable subspecies found in Africa. 5) The aye-aye, a nocturnal primate from Madagascar considered one of the ugliest animals. 6) The fennec fox, the smallest and cutest fox known for its large ears. 7) The wallaby, a miniature kangaroo found in Australia.

JAMES WEBB STUDY THE MASSIVE BLACK HOLE SEEDSSérgio Sacani
The pathway(s) to seeding the massive black holes (MBHs) that exist at the heart of galaxies in the present and distant Universe remains an unsolved problem. Here we categorise, describe and quantitatively discuss the formation pathways of both light and heavy seeds. We emphasise that the most recent computational models suggest that rather than a bimodal-like mass spectrum between light and heavy seeds with light at one end and heavy at the other that instead a continuum exists. Light seeds being more ubiquitous and the heavier seeds becoming less and less abundant due the rarer environmental conditions required for their formation. We therefore examine the different mechanisms that give rise to different seed mass spectrums. We show how and why the mechanisms that produce the heaviest seeds are also among the rarest events in the Universe and are hence extremely unlikely to be the seeds for the vast majority of the MBH population. We quantify, within the limits of the current large uncertainties in the seeding processes, the expected number densities of the seed mass spectrum. We argue that light seeds must be at least 103 to 105 times more numerous than heavy seeds to explain the MBH population as a whole. Based on our current understanding of the seed population this makes heavy seeds (Mseed > 103 M⊙) a significantly more likely pathway given that heavy seeds have an abundance pattern than is close to and likely in excess of 10−4 compared to light seeds. Finally, we examine the current state-of-the-art in numerical calculations and recent observations and plot a path forward for near-future advances in both domains.

In this talk I will describe some recent ideas to find gravitational waves from supermassive black holes or of primordial origin by studying their secular effect on the orbital motion of the Moon or satellites that are laser ranged.
Anti-Universe And Emergent Gravity and the Dark UniverseSérgio Sacani
Recent theoretical progress indicates that spacetime and gravity emerge together from the entanglement structure of an underlying microscopic theory. These ideas are best understood in Anti-de Sitter space, where they rely on the area law for entanglement entropy. The extension to de Sitter space requires taking into account the entropy and temperature associated with the cosmological horizon. Using insights from string theory, black hole physics and quantum information theory we argue that the positive dark energy leads to a thermal volume law contribution to the entropy that overtakes the area law precisely at the cosmological horizon. Due to the competition between area and volume law entanglement the microscopic de Sitter states do not thermalise at sub-Hubble scales: they exhibit memory effects in the form of an entropy displacement caused by matter. The emergent laws of gravity contain an additional ‘dark’ gravitational force describing the ‘elastic’ response due to the entropy displacement. We derive an estimate of the strength of this extra force in terms of the baryonic mass, Newton’s constant and the Hubble acceleration scale a0 = cH0, and provide evidence for the fact that this additional ‘dark gravity force’ explains the observed phenomena in galaxies and clusters currently attributed to dark matter.

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.
TOPIC OF DISCUSSION: CENTRIFUGATION SLIDESHARE.pptxshubhijain836
Centrifugation is a powerful technique used in laboratories to separate components of a heterogeneous mixture based on their density. This process utilizes centrifugal force to rapidly spin samples, causing denser particles to migrate outward more quickly than lighter ones. As a result, distinct layers form within the sample tube, allowing for easy isolation and purification of target substances.
Discovery of An Apparent Red, High-Velocity Type Ia Supernova at 𝐳 = 2.9 wi...Sérgio Sacani

. The transient was identified in deep James Webb Space Telescope (JWST)/NIRCam imaging from the JWST Advanced Deep Extragalactic Survey (JADES) program. Photometric and spectroscopic followup with NIRCam and NIRSpec, respectively, confirm the redshift and yield UV-NIR light-curve, NIR color, and spectroscopic information all consistent with a Type Ia classification. Despite its classification as a likely SN Ia, SN 2023adsy is both fairly red (

Ca-rich population. Although such an object is too red for any low-

cosmological sample, we apply a fiducial standardization approach to SN 2023adsy and find that the SN 2023adsy luminosity distance measurement is in excellent agreement (

Ca-rich SNe Ia, SN 2023adsy is standardizable and gives no indication that SN Ia standardized luminosities change significantly with redshift. A larger sample of distant SNe Ia is required to determine if SN Ia population characteristics at high-

truly diverge from their low-

counterparts, and to confirm that standardized luminosities nevertheless remain constant with redshift.

OH ! WHAT A SENSE
Like us the animals also require a battery of senses
for various purposes including tracking down food
but some rely more on one more highly developed
sense than another and it makes all the difference :
The Starfish , Kiwis , dogs ,wolves, and many others
rely mainly on their power of smelling through ‘nose’
but ‘nose’ of Kiwi is in its beak , of starfish in its arms !
and of Indonesia’s Komodo dragon is in its tongue, hence
it can ‘taste’ the slightest trace of smell-even single molecules .
Kiwis can smell worms 3 cms underground
and Grey wolves their prey 2.5 kms away .
Eagles, hawks, kites and scavenger birds
have a very keen eyesight but frogs can’t
‘see’ well, even though they have large eyes
and detect prey’s moves using special receptors
in the retina at the back of their eyes .
2. Strange events 19
Antelopes and foxes rely on highly sensitive ears ;
In fact bat-eared foxes of Africa listen for insects
under the ground-even termites moving inside tunnels .
But hexapoda Pond skaters ,although they have no ‘ears’
find their prey by detecting ripples in water ;In fact they are
natural mathematicians catching insects trapped in water’s
surface film by calculating the direction of origin of ripples .
The Pipistrelle bat of North America has
a built in barometer –the Vitali organ in its ears
with which this cave dweller can sense whether or
not weather outside is favourable for hunting insects .
