Mammals are classified into several groups based on how their young develop. Marsupials carry their young in pouches after they are born. Monotremes lay eggs that hatch outside the body. Placental mammals exchange nutrients between the mother and embryo through the placenta. There are many types of placental mammals including those that live on land or in water, fly, have hooves or trunks. Convergent evolution has led to similar structures developing in different mammals living in similar climates.

Diversity Of Mammals Monotremes
Monotremes are a special group of mammals that share characteristics with reptiles. They lay soft-shelled eggs and incubate them for 10 days like reptiles. Monotremes also have a cloaca, a single bodily opening, like reptiles. There are only two monotreme species - echidnas, which are spiny anteaters found in Australia and New Guinea, and have either short or long beaks, and platypuses, which are one of the few poisonous mammals and live in water hunting for food.
Major orders of placental mammals
This document outlines the major orders of placental mammals, including their defining characteristics and examples. It discusses 12 orders: Artiodactyla which have an even number of toes and include pigs and cattle; Perissodactyla which have an odd number of toes and include horses and rhinos; Cetacea which are aquatic and include whales and dolphins; Primates which are tree-dwellers and include humans, apes and monkeys; Rodentia which make up over 40% of mammals and include mice and beavers; Chiroptera which can fly and are represented by bats; Xenartha which have few teeth and include anteaters and sloths; Sirenia which are aquatic herbivores
Diversity Of Mammals Marsupials
Marsupials are mammals whose young develop in pouches. Examples include kangaroos, koalas, wombats, and Tasmanian devils. Kangaroos have strong tails and legs to jump long distances. Koalas mainly eat eucalyptus leaves and sleep 16-18 hours a day due to low metabolism. Wombats dig burrows with claws and teeth. Tasmanian devils are the largest carnivorous marsupials and get their name from loud fighting noises. While Australians may joke about dangerous "drop bears," these do not actually exist.
Diversity Of Mammals Placental Mammals
Placental mammals exchange nutrients and gases between the mother and embryo through the placenta. This includes humans and most other mammals. Mammals are divided into groups based on traits like number of toes and diet. Carnivores like bears eat meat but can also consume plants. Cetaceans like whales are carnivorous marine mammals. Bats are the only mammals that can truly fly and feed on insects, fruit, and nectar. Rodents have sharp front teeth and eat plants and wood. Primates like lemurs have complex behaviors and brains unlike other animals. Proboscideans like elephants have trunks.
Evolution of mammals by Łukasz O
The earliest mammals appeared around 210 million years ago at the end of the Triassic period. During the Jurassic period, these small mammal-like creatures did not change much in their evolution. Synapsids were mammal-shaped reptiles that occurred from the Carboniferous to the early Jurassic and gave rise to modern mammals. Most modern mammals are placental and develop inside the mother's uterus, receiving nutrients from the placenta. Mammals have diverse diets ranging from carnivores, herbivores, insectivores to omnivores. They are divided into three main groups: monotremes, marsupials, and placentals.
Mammals
Mammals are named after their mammary glands, which produce milk to feed their young. They are classified into three main groups: monotremes, which lay eggs; marsupials, which carry their young in pouches; and placentals, which carry young in the womb. Placental mammals are further divided into 11 orders based on characteristics like diet, habitat, locomotion and teeth. Some key orders include insectivores, bats, rodents, rabbits, armadillos, whales, dugongs, elephants, carnivores like dogs, hoofed animals, and primates.
Animalia
The document discusses the Kingdom Animalia. It defines Animalia as the kingdom that comprises all multicellular animals and notes there are over 9 million animal species found on Earth, ranging from single-celled to the polar bear and blue whale. All animal kingdom organisms are multicellular, eukaryotic, heterotrophic organisms that rely on other organisms for food. General characteristics of the kingdom include being multicellular, eukaryotic organisms that have multiple cells with mitochondria and depend on other organisms for nutrition.

Mammals
The document discusses the characteristics of mammals. It notes that mammals are vertebrates that have fur or hair, are warm-blooded, nourish their young with milk, breathe air, and have four limbs or fins with a four-chambered heart. It divides mammals into three main groups: monotremes that are egg-laying, marsupials that give birth to underdeveloped young that develop in the mother's pouch, and placental mammals that give birth to more developed young and have a longer gestation period than marsupials. Finally, it notes that mammal diets can include carnivores that eat meat, herbivores that eat plants, omnivores that eat both plants and meat
Amphibians and reptiles
Amphibians live both on land and in water, having thin skin that allows absorption of water and oxygen. They go through a metamorphosis where larvae with gills transform into adults with lungs on land. While amphibians were the first to move onto land, reptiles later evolved with thicker scaly skin and shells for their eggs, allowing full adaptation to life on land.
CLASSIFICATION OF MAMMALS
Mammals are classified into 5420 species within 152 families and 29 orders. The two subclasses are Prototheria and Theria. Prototheria contains monotremes like platypuses and echidnas that lay eggs. Theria contains marsupials in the infraclass Metatheria that give birth to immature young developing further in pouches, and placentals in Eutheria that give live birth to mature young. Marsupials include opossums and kangaroos, while placentals make up the majority of mammal species and include humans, whales, bats and more. Classification systems continue to evolve as new genetic and fossil evidence is discovered.

final monkey frog project
The Giant Waxy Monkey Frog is a species of frog found in tropical South American rainforests from Brazil to Peru. It lives on land but returns to water to breed during the rainy season. Males attract females by croaking, and eggs are laid in nests above water that hatch into aquatic larvae. Larvae develop lungs and legs through metamorphosis before becoming terrestrial frogs. However, the Giant Waxy Monkey Frog is threatened by habitat loss, pollution, disease, and climate change.

Reptiles Juju
Reptiles are vertebrates with scaly skin, lungs, and terrestrial eggs that allow them to live fully on land. They evolved from amphibian ancestors and came to dominate during the Triassic period, though most dinosaurs went extinct at the end of the Cretaceous period due to volcanic eruptions and an asteroid impact. Modern reptiles include snakes, lizards, crocodilians, turtles, and the tuatara; they regulate their body temperature through environmental interactions, have two-chambered hearts, and reproduce through internal fertilization or ovoviviparity. Many reptile species are endangered due to habitat destruction and overhunting.
Reptiles Life Science 15 4
Reptiles first appeared nearly 280 million years ago and include turtles, crocodiles, and lizards and snakes. They have dry scaly skin, lay amniotic eggs with membranes to protect embryos, and show little maternal care once eggs are laid. Modern reptiles descended from early reptiles and vary widely in size, shape, color, habitat, diet, and behavior.

For example, it notes that mammals are warm-blooded and their babies drink milk, while fish have inhabited Earth for over 450 million years. The document also explains characteristics of invertebrate groups such as arthropods, which make up 80% of known animal species.
Amphibians 10-8 miryana bedros yuliya
Amphibians are a class of vertebrate animals that live both on land and in water. They have moist skin, four limbs, undergo metamorphosis from an aquatic larval stage to a terrestrial adult stage, and include frogs, salamanders and caecilians. The largest orders are Anura (frogs), Urodela (salamanders), and Gymnophiona (legless caecilians). Amphibians play an important role in ecosystems and some species are used in medical research.
Classificationofanimals
This document provides a classification of animals, dividing them into vertebrates and invertebrates. Vertebrates include mammals, fish, reptiles, birds and amphibians, which are further defined by their key characteristics such as how they reproduce, regulate body temperature, breathe and move. Invertebrates make up 97% of the animal kingdom and lack backbones, including sponges, corals, jellyfish, worms, starfish, mollusks, arthropods and insects. They are grouped according to their physical traits and structures.
Kingdom Animalia Phylum Chordata Class Reptalia
In order for us to understand how all living organisms are related, they are arranged into different groups. The more features that a group of animals share, the more specific the group is. Animals are given scientific names so that people all around the world can communicate about animals, no matter what language they speak (these names are traditionally Latin words). Animals belong to a number of different groups, starting with the animal kingdom.
Kingdom
All living organisms are first placed into different kingdoms. There are five different kingdoms to classify life on Earth, which are Animals, Plants, Fungi, Bacteria, and Protists (single-celled organisms).
Phylum
The animal kingdom is divided into 40 smaller groups, known as phylum. Here, animals are grouped by their main features. Animals usually fall into one of five different phylum which are Cnidaria (invertebrates), Chordata (vertebrates), Arthropods, Molluscs and Echinoderms.
Class
The phylum group is then divided into even smaller groups, known as classes. The Chordata (vertebrates) phylum splits up into Mammalia (Mammals), Actinopterygii (Bony Fish), Chondrichthyes (Cartilaginous Fish) , Aves (Birds), Amphibia (Amphibians) and Reptilia (Reptiles).
Order
Each class is divided into small groups again, known as orders. The class Mammalia (Mammals), splits into different groups including Carnivora, Primate, Artiodactyla and Rodentia.
Family
In every order, there are different families of animals which all have very similar features. The Carnivora order breaks into families that include Felidae (Cats), Canidae (Dogs), Ursidae (Bears), and Mustelidae (Weasels).
Genus
Every animal family is then divided into small groups known as genus. Each genus contains animals that have very similar features and are closely related. For example, the Felidae (Cat) family contains genus including Felis (small Cats and domestic Cats), Panthera (Tigers, Leopards, Jaguars and Lions) and Puma (Panthers and Cougars).
Species
Each individual species within the genus is named after it's individual features and characteristics. The names of animals are in Latin so that they can be understood worldwide, and consist of two words. The first word in the name of an animal will be the genus, and the second name indicates the specific species.

Kingdom: Animalia (Animal)
Phylum: Chordata (Vertebrate)
Class: Mammalia (Mammal)
Order: Carnivora (Carnivore)

(1) Sponges are simple aquatic animals that live in water and have pores that intake and output water. They come in different shapes and have skeletons made of either silicon or lime. Sponges reproduce both sexually and asexually.
(2) Cnidarians are a phylum of aquatic animals that include jellyfish, corals, sea anemones and hydra. They have radial symmetry and live in bodies of water. Cnidarians reproduce both sexually, going through polyp and medusa stages, and asexually by splitting their bodies. They feed through passive predation using stinging cells.
Classification of animals
This document classifies and describes the key characteristics of vertebrates and invertebrates. Vertebrates include mammals, fish, reptiles, birds and amphibians, and can be found around the world. They are divided into groups based on traits like whether they lay eggs, have feathers or fur, breathe through lungs or gills, and how they regulate their body temperature. Invertebrates make up 97% of animal species and lack backbones, including insects, worms, sponges, jellyfish, starfish, mollusks and arthropods. They are grouped by their exoskeleton, body structure and environment.

Science fungi p.point
The document discusses the classification of fungi in the kingdom, describing how they are classified based on their structure and reproduction methods. It identifies some common types of fungi, including molds, zygomycetes, sac fungi known for their reproductive sacs, club fungi named for their club-shaped reproductive structures, and imperfect fungi whose reproductive phases are not observable. It provides links to additional information and sources.
Amazing Sperm Plants
Flowering plants first appeared around 135 million years ago and have since diversified greatly. They have flowers that attract pollinators like bees, helping the plants reproduce. There are over 500 ways to classify flowers based on their many variations from crossed genes between species. Angiosperms can be divided into two main classes - monocots and dicots - based on their seeds and seedling structure. Monocots have one seed and dicots have two. Angiosperms can also be classified as woody, herbaceous, annual, perennial, or biennial based on characteristics like their stem structure and lifespan.
Cnidarians
Cnidarians are a phylum of aquatic animals that include jellyfish, corals, sea anemones and hydroids. They live in oceans around the world, from the surface waters to the deep sea. Cnidarians have two life stages - a free-swimming medusa stage and a stationary polyp stage, where they are attached to a surface. Their life cycle often involves both a medusa and polyp form.
Stems
Stems perform several functions like producing leaves, branches, and flowers. They transport substances between roots and leaves and hold leaves up towards sunlight. Monocots have vascular bundles arranged in the stem, while dicots and gymnosperms have vascular bundles arranged in cylinders with xylem and phloem tissue. Primary growth occurs through cell division at the stem tip in all seed plants, resulting in increased length. Secondary growth occurs through thickness, with cork cambium forming the outer covering and vascular cambium between vascular tissues producing new layers of xylem wood.
Gretchen Harrigan
Fungi are living organisms that are more closely related to animals than plants. They absorb nutrients from decaying matter in the soil rather than producing their own food through photosynthesis. Fungi are made up of fine threads called hyphae that intertwine to form a tangled web-like structure called a mycelium. Hyphae may contain cross walls that divide them into separate cells. Fungi play an essential role in the environment by aiding plant root function and breaking down dead organic material.
Chordates
Seedless vascular plants reproduce without seeds and have structures that transport water and nutrients throughout the plant. They include club mosses, horsetails and ferns, which have roots, leaves and stems. The dominant stage in a fern's life cycle is the sporophyte, which is diploid.
Leaves, Roots, And Stems
Sponges are multicellular animals that live attached to surfaces in marine environments. They filter feed by drawing water through their bodies to absorb nutrients while releasing waste. Sponges can reproduce both sexually through internal fertilization or asexually. There are over 5,000 known sponge species. Sponges were some of the earliest forms of animal life on Earth.
This Is My Power Point
Leaves are the main organs for photosynthesis in plants. They are made up of a thin flattened blade connected by a petiole stalk to the stem. The blade is covered by an epidermis layer and vascular tissues which transport water and nutrients. Mesophyll tissue inside the leaf contains chloroplasts that perform photosynthesis, producing carbohydrates that move through phloem vessels to the rest of the plant. Sunlight is absorbed by palisade mesophyll cells at the top and travels through spongy mesophyll cells at the bottom. Stomata pores allow gases like oxygen and carbon dioxide to diffuse in and out for photosynthesis. Water lost through transpiration is replaced through xylem vessels in the vascular tissue
Powerpoint
Archaebacteria differ from eubacteria in that they lack peptidoglycan and have distinct membrane lipids, and their DNA sequences are more similar to eukaryotes. Archaebacteria thrive in harsh environments like digestive tracts, salty lakes, and oxygen-depleted mud. Prokaryotes use flagella for movement and undergo cellular respiration for energy. They can also exchange genes between cells through conjugation. Prokaryotes reproduce through binary fission, doubling in size before dividing into two daughter cells.

1) Different types of algae, called protists, are described including euglenophytes, dinoflagellates, and chrysophytes.
2) Euglenophytes are plantlike protists that reproduce through binary fission and have two flagella but no cell wall.
3) Dinoflagellates can be photosynthetic or heterotrophic, reproduce through binary fission, and store DNA but not histones like other organisms.
Fishes
This document discusses the characteristics, evolution, feeding, and respiration of fish. It notes that fish generally have paired fins, scales, and gills. Originally fish were armored and jawless, but in the Devonian Period fish evolved paired fins and jaws. Fish can feed in different ways depending on their environment, including herbivores, carnivores, parasites, filter feeders, and detritus feeders. Gas exchange occurs through gill filaments and blood circulates through fish in one loop.
Primates And Human Origins Powerpoint
The document discusses primates and human origins. It defines hominids and primates, noting that hominids evolved to walk upright and have opposable thumbs, while primates have binocular vision and well-developed brains and limbs. It outlines the two hypotheses for modern human evolution - the multi-regional model suggesting independent evolution in several places, and the out-of-Africa model where Homo sapiens first evolved in Africa from earlier species like Homo habilis, Homo ergaster, and Homo erectus. It also discusses Homo neanderthalensis and evidence that Homo sapiens lived alongside them around 50,000-40,000 years ago.
Viruses Final Presentation!
There are three main types of bryophytes: mosses, which commonly grow in moist areas; liverworts, which resemble flat leaves attached to the ground and get their name from resembling a liver; and hornworts, which are found in soil damp year-round. Bryophytes are non-vascular plants that are typically found in damp, moist environments like evergreen forests and go through a life cycle of growth, reproduction, and dispersal.
Roots, Stems, and Leaves Power Point
Viruses are particles that can only reproduce by infecting living cells and contain nucleic acid, protein, and sometimes lipids. They do not have fossils but may have impacted life's history. Viruses use capsids made of protein to enter host cells. Some viruses infect bacteria while others contain RNA as their genetic material or are made solely of protein. Viral infections can be lytic, causing the cell to burst, or lysogenic where the virus embeds its DNA into the host cell DNA. Many human diseases are caused by viruses such as polio, measles, AIDS, influenza, and rabies.
Amphibians
Amphibians are vertebrates that typically live both on land and in water. They evolved adaptations like stronger bones and limbs that allowed them to move on land while still having lungs and gills. There are three main groups of amphibians - salamanders, frogs and toads, and caecilians. Amphibians have defenses like poisonous skin secretions and camouflage to protect themselves from predators.

Ecology Of Fungi
Fungi are heterotrophs that obtain nutrients by breaking down and absorbing organic matter using digestive enzymes and thread-like mycelium. As decomposers, fungi recycle nutrients by breaking down dead organisms and waste. Some fungi are also parasites that can cause diseases in plants, animals, and humans. Fungi also form symbiotic relationships with photosynthetic organisms like lichens and plant roots through mycorrhizae.

Birds have wings and feathers that allow them to fly. They maintain a constant internal body temperature and have specialized features like bills and digestive systems that help them survive. There are many groups of birds including songbirds, raptors, and flightless birds. Birds play important ecological roles like seed dispersal and pest control. They have been around for over 150 million years.
Reptiles Sigrid Ryan
Reptiles are scaly animals that live in warm areas and eat plants or small animals. There are several types of reptiles including lizards, snakes, crocodilians, turtles, and tortoises. Reptiles are ectothermic, meaning they rely on external heat sources like sunlight to regulate their body temperature. While dinosaurs were the largest reptiles to ever live, modern reptiles have diversified to fill ecological niches through evolution from a common ancestor.
