Biology 28 1 introduction to the arthropods
Arthropods have an exoskeleton made of chitin that protects their body and supports their appendages. They breathe through tracheal tubes or book lungs and release waste through malpighian tubules. As they grow, arthropods molt and shed their exoskeletons.
Arthropods and insect worksheets (answers)
This document defines arthropods and discusses their characteristics and major groups. Arthropods have jointed appendages and include insects, arachnids, and crustaceans. Insects have three body segments and six legs attached to their thorax. They undergo either complete metamorphosis with stages of egg, larva, pupa, and adult, or incomplete metamorphosis with stages of egg, nymph, and adult. The larva is also called a caterpillar and eats heavily to store energy for metamorphosis.

Their feeding process involves using a muscular gizzard to break down food and a crop to store and moisten it.
Insect respiratory system
1. Insects have respiratory systems that allow oxygen to enter their bodies through spiracles and move through tracheae to cells, while carbon dioxide is removed.
2. Air enters through spiracles and moves through elastic tracheal tubes to smaller tracheoles near cells, facilitating gas exchange. Some insects also have air sacs that act as reservoirs.
3. The number and placement of spiracles varies and classifies insects into different respiratory system types, from holopneustic to apneustic systems. Aquatic insects can take oxygen from the water surface using siphons or air bubbles.
Birds
Birds are a diverse class of vertebrates with over 10,500 species worldwide. They are distinguished by their feathers, though many dinosaurs were also feathered. Bird anatomy is highly adapted for flight, with light skeletons, powerful muscles, and specialized respiratory, circulatory, and digestive systems. Their reproduction varies but generally involves laying eggs in clutches and caring for offspring.

External genitalia like the ovipositor are also discussed, which can take different forms like needle-like, sword-like, or modified for stinging.
Introduction To The Arthropods
Anthropods have an exoskeleton made of chitin that protects and supports their body, and they have appendages like legs and antennae that extend from their body. They breathe through a tracheal tube system with openings called spiracles, and some land arthropods use book lungs for respiration, while malpighian tubules extract waste from their blood into feces. Arthropods grow by molting and replacing their exoskeleton.

- Insects have small bodies, typically under 2.5 cm, but range in size from under 1 mm to over 25 cm. They are found in nearly all habitats on Earth.
Chordata
1) The phylum Chordata is defined by five key characteristics present during some life stage: a notochord, pharyngeal slits, an endostyle or thyroid gland, a post-anal tail, and a dorsal tubular nerve cord.
2) The phylum contains three subphyla: Urochordata (tunicates), Cephalochordata (lancelets), and Vertebrata (vertebrates).
3) Vertebrates are the most complex group and possess an internal skeleton, segmented muscles, complex skin, and more advanced digestive, respiratory, circulatory, nervous and excretory systems compared to other chordates.
Terminologies related to insect Morphology
1. The document discusses insect morphology and provides terminology related to the external structures of insects.
2. It describes the three main body regions of insects - the head, thorax, and abdomen. For each region, it lists the major external structures like eyes, antennae, legs, wings.
3. Terminology for wings, legs, and life stages including different types of metamorphosis are also defined. The document serves as a glossary of important morphological terms for describing the external anatomy of insects.
Entomology (Insect Parts)
The thorax is the middle body region of insects and contains three segments - the prothorax, mesothorax, and metathorax. Each segment contains a pair of legs and, in many adult insects, one or two pairs of wings. The thorax houses muscles that power the legs and wings. It is composed of rigid exoskeleton plates on the dorsal, ventral, and lateral sides of each segment. The thorax contains three pairs of legs and, in most adult insects, one or two pairs of wings that are adapted for functions like flight, protection, and sensory roles.
Class insecta
1. Insects are a diverse class of arthropods that possess three pairs of jointed legs, a three-part body plan consisting of head, thorax, and abdomen, and usually a pair of antennae and compound eyes.
2. They represent over half of all known living organisms, with an estimated 6-10 million species, and dominate nearly all land and freshwater environments.
3. Insects breathe through a tracheal system and have an exoskeleton instead of an internal skeleton, and most undergo either complete or incomplete metamorphosis from egg to larva to pupa to adult.
Aves
1) Birds are endothermic vertebrates with feathers that descended from bipedal dinosaurs.
2) They have several adaptations for flight including lightweight bones filled with air sacs, loss of teeth replaced by beaks, and reduced wrist, palm, and digit bones.
3) The earliest known bird is Archaeopteryx from the Jurassic period, which had both reptilian and avian features like teeth, a long tail, and feathers.
Gas exchange
The respiratory system of birds consists of external nares, pharynx, trachea, air sacs, and lungs. Air flows through the nasal passages and pharynx into the trachea, which divides into bronchi that lead to air sacs throughout the body and lungs. The lungs contain small tubes called parabronchi that divide into air capillaries for gas exchange. During respiration, the volume of the thorax changes and the air sacs alternately expand and contract, driving continuous airflow through the lungs during both inhalation and exhalation for highly efficient oxygen uptake to support birds' high metabolic rates and ability to fly at high altitudes.

Phylum Chordata
- Chordates evolved from invertebrates and display traits like bilateral symmetry, segmentation, and a gut tube. Chordates are distinguished by having a notochord, dorsal nerve cord, pharyngeal slits, post-anal tail, and myotomes (blocks of muscle) at some stage of their life.
- Vertebrates are chordates that have evolved additional traits like a skull, vertebral column, and endoskeleton. They have undergone further diversification into groups like fish, amphibians, reptiles, birds, and mammals which have specialized for various environments.
Chordata - Bio 11
- Chordates evolved from invertebrates and display traits like bilateral symmetry, segmentation, and a gut tube. Chordate evolution led to specializations like variations in limb structure in mammals.
- The four defining chordate features present in embryos and sometimes adults are a notochord, dorsal nerve cord, pharyngeal slits, and a post-anal tail.
- Vertebrates are chordates that evolved a cartilage or bone skull, vertebral column, and other adaptations to land like lungs and efficient kidneys. Major vertebrate groups include fish, amphibians, reptiles, birds, and mammals.

The document provides an overview of invertebrate animal classification, describing key characteristics of major phyla. It discusses porifera, cnidarians, flatworms, nematodes, annelids, molluscs, arthropods, and echinoderms. For each group, it describes anatomy, examples of types of animals in the group, and sometimes life cycles or additional details.
Echinoderms
Echinoderms have a spiny skin and bone plates just below it that form an endoskeleton. Fish are cold-blooded vertebrates that live in water and breathe through gills. They have scales, fins, and well-developed circulatory, digestive and nervous systems. Invertebrates lack a backbone and have less developed nutrition and sensory systems compared to vertebrates. They may have exoskeletons, endoskeletons, or no skeleton.

Biology 26.1
This document defines key terms related to the animal kingdom, including invertebrates, vertebrates, feedback inhibition, blastula, protostomes, deuterostomes, radial symmetry, bilateral symmetry, and more. It describes animals as multicellular, eukaryotic heterotrophs and outlines their essential functions of feeding, respiration, circulation, excretion, response, movement, and reproduction. Complex animals are noted to have high cell specialization, internal organization, bilateral symmetry, a head with sense organs, and a body cavity.
Biology 26.2
Sponges contain specialized cells like choanocytes that use flagella to move water through the sponge for feeding, respiration, circulation, and excretion. They have structures like spicules made of calcium carbonate or silica that form their skeleton, and archaeocytes that produce these spicules. Sponges reproduce through internal fertilization and larval stages, and some can form protective gemmules during unfavorable conditions.
Biology 22.5
Angiosperms are flowering plants that reproduce sexually through flowers. Flowers contain ovaries that surround and protect seeds. Angiosperms are divided into monocots and dicots based on whether their seeds have one cotyledon (monocot) or two cotyledons (dicot). Flowering plants can also be annuals, biennials, or perennials depending on whether their life cycle is one, two, or more than two years.
Earth science 13.1
The document discusses Precambrian time from 4.56 billion years ago until the Cambrian period over 4 billion years later. It describes shields as flat expanses of ancient metamorphic rock within continental interiors. Stromatolites are layered mounds formed from algae trapping sediment and calcium carbonate. Earth's original atmosphere lacked oxygen but primitive organisms evolved photosynthesis which began releasing oxygen into the atmosphere around 2.5 billion years ago.
Earth science 13.4
The Cenozoic Era saw the rise of mammals as the dominant land animal, replacing reptiles. Flowering plants known as angiosperms also became the dominant land plant over gymnosperms. Major geological events like mountain building, volcanism, and earthquakes occurred in western regions due to plate tectonics during this era. Mammals were better adapted than reptiles for more active lifestyles through bearing live young and maintaining steady body temperatures.
Earth science 13.2
The Paleozoic Era saw an explosion of life, as the continents of Gondwana and Laurasia formed most of the southern and northern portions of the supercontinent Pangea. During the Cambrian, Ordovician, and Silurian periods, life was restricted to the seas surrounding Gondwana, which contained the continents of present-day South America, Africa, Australia, Antarctica, and parts of Asia. By the end of the Paleozoic Era, around 400 million years ago, all continents had fused into the single landmass of Pangea, and plants first began moving from waterside habitats onto land.
Earth science 13.3
The Mesozoic era was the Age of Reptiles, where reptiles like dinosaurs quickly became the dominant land animals due to developing shelled eggs. Gymnosperms also dominated as the prominent plant during this time. A major geological event was the breakup of the supercontinent Pangea. Many reptile groups went extinct at the end of the Mesozoic era.
Earth science 9.1
Continental drift is the hypothesis that the continents were once joined together and have since drifted apart. Originally proposed by Wegener, it suggests the continents were part of a supercontinent called Pangaea approximately 200 million years ago that has since broken apart, moving the landmasses into their current positions. Fossil and rock evidence support this idea, including matching fossil organisms and mountain ranges found on separate continents today that indicate the continents were once joined.
Earth science 8.2
This document discusses seismograms and the different types of seismic waves that are recorded, including P waves, S waves, and surface waves. It explains that seismograms amplify and electronically record ground motion from earthquakes, allowing scientists to determine the epicenter location using travel time graphs from multiple seismographs. The document also covers historical intensity and magnitude scales used to describe earthquake size and introduces moment magnitude as the most widely used scale today because it estimates the energy released.
Biology 2.4
Chemical reactions involve reactants being converted into products through breaking and forming chemical bonds, requiring a minimum amount of energy called the activation energy. Catalysts like enzymes speed up reactions by lowering this activation energy, with enzymes being protein catalysts that facilitate substrate reactions within cells.
Earth science 12.3
This document discusses radiometric dating and how it is used to determine the absolute ages of rocks and minerals. It explains key concepts such as radioactivity, half-life, and how comparing ratios of radioactive isotopes like carbon-14 and carbon-12 can be used to calculate radiocarbon dates for samples. Radiometric dating relies on the fact that radioactive isotopes decay at a constant rate and comparing the amounts of parent and daughter isotopes allows the age of a sample to be estimated.

Earth science 7.3
Wind shapes landscapes through processes like deflation, desert pavement formation, and loess and dune deposition. Deflation is the lifting and removal of loose material by wind. Desert pavement is a layer of coarse pebbles created when wind removes finer material. Loess deposits are windblown silt deposits that form blanket-like layers, while dunes are ridges of wind-deposited sand that can vary in shape depending on wind and vegetation factors.
Earth science 7.2
Much of the weathered debris in deserts comes from mechanical weathering like alluvial fans formed where stream slopes abruptly decrease. While chemical weathering is less common, over long periods clays and thin soils can form. Desert streams are ephemeral, only flowing after rain, and often drying up before reaching oceans due to evaporation and soil infiltration. Most desert erosion comes from running water, though wind also erodes deserts, water does the most erosional work.
Earth science 7.1
Glaciers are large masses of ice that originate on land from compacted snow and move due to gravity. During an ice age, large ice sheets form on continents and flow outward, carving U-shaped valleys and depositing unsorted sediment called till. Valley glaciers are smaller glaciers confined to mountain valleys that flow due to plastic deformation and basal sliding between the ice and bedrock.
Earth science 6.3
Groundwater exists below the surface in the saturated zone where all spaces between rock and sediment are filled with water. The water table marks the top of this zone, and groundwater moves slowly through porous and permeable materials. Springs form where the water table intersects the surface, and overuse or contamination can threaten groundwater supplies in some areas. Karst regions have irregular terrain with sinkholes caused by erosion of soluble rock by groundwater in caverns below the water table.
Earth science 6.2
This document defines key terms related to streams and their processes, including bed load, capacity, alluvium, delta, natural levee, floodplain, flood, drainage basin, divide. It also describes concepts such as how streams erode and deposit sediment according to flow velocities, and how flooding occurs and can be mitigated. The overall work of streams is to shape the landscape through erosion, transportation, and deposition of sediment within drainage basins.
Earth science 6.1
The document discusses key concepts about running water and the water cycle. It defines terms like infiltration, transpiration, gradient, stream channel, discharge, tributary, base level, and meander. It explains that water constantly circulates among the oceans, atmosphere, geosphere, and biosphere in the water cycle. Balance in the cycle means annual precipitation equals evaporation globally. A stream's ability to erode and transport materials depends on its velocity, while gradient decreases and discharge increases from headwaters to the mouth.
Earth science 5.2
Soil is formed from weathered rock and organic matter and varies in composition with depth, forming distinct horizons. It consists of minerals, organic matter, water, and air. The type of soil depends on the parent material and climate, with pedalfer soils found in humid regions, pedocal soils in drier areas, and laterite soils in the tropics. However, human activities like agriculture and construction can accelerate erosion and damage soil formation.
