Biodiversity 12
Biodiversity refers to the variety of life on Earth at all levels, from genes to ecosystems. It can be measured in five levels: genetic diversity within species; species diversity within communities; community diversity within ecosystems; ecosystem diversity within biomes; and biome diversity across the planet. Species diversity has two components - species richness, which is the number of different species, and relative species abundance, which is the number of individuals of each species. Tropical rainforests generally have higher biodiversity than temperate regions due to factors like climate stability, habitat structure, competition and disturbance regimes.
5.05 classification and scientific names
Carolus Linnaeus developed a system of classification in the 18th century that is still used today called binomial nomenclature. It assigns every living thing a two-part scientific name - the first part being the genus, a broader group, and the second being the specific epithet or species, a more precise classification. Some examples given are Canis familiaris for the domestic dog and Panthera leo for the lion. This system provides a standardized Latin naming convention that is universally understood for living organisms.

Taxonomy
Taxonomy is the science of classifying organisms into groups based on their characteristics. Scientists have developed a hierarchical classification system with seven main categories - kingdom, phylum, class, order, family, genus, and species. This system allows organisms to be grouped from the broad kingdom level down to the specific species level. DNA analysis has furthered taxonomy by revealing evolutionary relationships between organisms that may not appear closely related physically.

Taxonomy
Taxonomy is the branch of biology that groups and names organisms. Biologists called taxonomists study taxonomy. Carolus Linnaeus developed a seven-level taxonomy system including kingdom, phylum, class, order, family, genus, and species to classify and organize organisms based on their similarities. This binomial nomenclature system uses the genus and species names to uniquely identify each organism, allowing scientists worldwide to communicate unambiguously about different species.
Invertebrates
This document summarizes the key characteristics of invertebrate animals. It describes that invertebrates lack a backbone or skeleton and have external shells or coverings. The main groups of invertebrates are described as mollusks, jellyfish, sponges, annelids, and arthropods. Arthropods are further broken down into insects, arachnids, crustaceans, and myriapods, all of which have jointed exoskeletons and legs. Mollusks are separated into bivalves, gastropods, and cephalopods. Sponges and echinoderms are also briefly characterized.

Reptiles
Reptiles are cold-blooded animals that first evolved around 330 million years ago. They are covered in scales or scutes and lay amniotic eggs, allowing them to reproduce on land. Reptiles are classified based on characteristics of their skin, skeleton, respiration and other features. There are three major subclasses - Anapsida which includes modern turtles, Synapsida which are mammal-like reptiles, and Diapsida which is the largest group and includes lizards, snakes and crocodilians. Orders within these subclasses differ in traits like teeth, limbs and diet. Reptiles inhabit diverse habitats globally except Antarctica, with some limitations due to their inability to regulate body temperature.

Insects, spiders, crabs, shrimp, millipedes, and centipedes are all arthropods. Arthropods have jointed feet, a segmented body, and an exoskeleton, a cuticle on the outside of their body. Arthropods have by far the greatest number of species of any animal group, at around 900,000 species
Vertebrata
This document summarizes the key characteristics of vertebrates. It discusses that vertebrates have an internal skeleton and true vertebral column, allowing for different muscle attachment points. They are bilaterally symmetrical and have features like a notochord, dorsal nerve cord, and paired gill pouches. Vertebrates are grouped into five classes - Agnatha, Chondrichthyes, Osteichthyes, Amphibia, Reptilia, Aves, and Mammalia. Each class possesses distinct skeletal structures and anatomical features that define their phylum and allow for different habitats and behaviors.

1) Descriptions of plant and animal cell structures and comparisons between eukaryotic and prokaryotic cells.
2) Explanations of three transport processes - diffusion, osmosis, and active transport - and examples of each in cells and organisms.
3) An overview of cell division through mitosis and its role in growth and repair of cells.
6 Inh Variation and Evolution.pptx
Here are the key steps in cloning plants:
1) Plants can reproduce asexually through processes like producing runners or stolons, which will grow into clones that are genetically identical to the parent plant.
2) For example, a spider plant grows a rooting side branch called a stolon that will become a clone of the parent plant. A gardener may also take cuttings from a desirable plant to grow into clones.
3) The clones are genetically identical to the original parent plant and are called clones. The only variation between clones will come from environmental factors, not genetic differences. Asexual reproduction produces clones while sexual reproduction produces offspring with genetic variation.

2 Organisation KnowIT.pdf
The document discusses the human digestive system as an organ system where organs like the mouth, esophagus, stomach, and intestines work together to digest and absorb food using enzymes. It explains that digestion breaks down large insoluble molecules into smaller soluble ones that can be absorbed, and this process relies on enzymes released by organs like the salivary glands, pancreas, and stomach. Key enzymes and their roles in breaking down carbohydrates, proteins, and lipids are identified.
3 Infection and Resp KnowIT.pdf
The document discusses different types of infectious diseases caused by pathogens such as viruses, bacteria, fungi and protists. It provides examples of viral diseases like measles and HIV, bacterial diseases including salmonella and gonorrhoea, and the fungal disease rose black spot and the protist disease malaria. The document explains how these diseases are transmitted and potential treatments or methods of control.
4 Bioenergetics KnowIT.pdf
Photosynthesis is the process by which plants produce glucose from carbon dioxide and water using energy from sunlight. The rate of photosynthesis is affected by several factors including carbon dioxide concentration, temperature, and light intensity, with each factor limiting the rate once a certain threshold is reached. Experiments can measure the rate of photosynthesis by counting oxygen bubbles produced over time as light intensity or other factors are varied.
6 inh variation evol knowit.pptx
Here are the key advantages summarized:
- Sexual reproduction leads to variation in offspring through meiosis and mixing of genes from two parents. This variation provides a survival advantage if the environment changes.
- Asexual reproduction requires only one parent so it is more efficient in terms of time, energy and resources as no mate needs to be found. However, offspring are identical clones with no genetic variation.
- Both types of reproduction have advantages depending on circumstances. Sexual reproduction promotes variation for changing environments while asexual is more efficient for stable conditions.
7 ecology knowit.pptx
The document discusses adaptations, interdependence and competition within ecological communities. It describes the different levels of ecological organization, including organisms, populations, communities, and ecosystems. Communities consist of many interacting populations that depend on each other through relationships like pollination, seed dispersal, and predator-prey interactions. Both biotic factors (living things) and abiotic factors (non-living things) influence communities. Organisms within communities compete for resources and adapt in ways that allow them to survive and reproduce under the prevailing environmental conditions. Competition and adaptations both help maintain a balanced community structure.
6.6 Hormones Homeo and Repro (Chris Paine)
Thyroxin is a hormone produced by the thyroid gland that controls metabolism and affects growth and physiological processes. It regulates the metabolic rate and helps control body temperature. Most hormones affect multiple target tissues and have more than one effect. The document discusses thyroid hormones and their roles, as well as hormones involved in the menstrual cycle and their feedback mechanisms.
6.5 neurons and synapses (chris paine)
The document discusses neurons and synapses in the human brain. It begins by showing an image of a small segment of the human brain, with lines representing neurons and dots representing synapses. It notes that synapses are crucial for neural communication and thought. While the number of brain cells does not increase much after birth, the connections between neurons through synapses continue developing. The document then provides explanations of key concepts regarding neurons, synapses, and neural signaling. It explains how neurons transmit electrical signals, how synapses allow signals to be transmitted between neurons, and how signals propagate along axons through action potentials.
6.4 Gas Exchange (Chris Paine)
The document discusses gas exchange in the lungs. It explains that two processes maintain concentration gradients of oxygen and carbon dioxide between the alveoli and blood: 1) circulation brings deoxygenated blood to the alveoli, and 2) ventilation increases and decreases lung volume through muscle contractions, ensuring a supply of oxygenated air reaches the alveoli. The diaphragm and intercostal muscles contract during inhalation to inflate the lungs, allowing for gas exchange by diffusion across the alveoli.
6.3 defence (chris paine)
The human body has structures and processes that resist the continuous threat of invasion by pathogens. These include leukocytes that ingest and destroy pathogens, as well as physical barriers like the skin and mucous membranes. The body also has mechanisms for blood clotting to prevent the entry of pathogens through cuts in the skin. Lymphocytes produce antibodies that provide specific immunity against particular pathogens. While antibiotics can treat bacterial infections by blocking bacterial processes, they are ineffective against viruses which lack metabolism and cannot be treated in the same way.
6.2 Blood System (Chris Paine)
The blood system continuously transports substances to cells and collects waste through three main types of blood vessels. Arteries carry blood away from the heart to tissues and have muscle and elastic fibers to maintain blood pressure. Capillaries have thin walls that penetrate tissues and allow for exchange. Veins collect blood from tissues and return it to the heart, using valves to prevent backflow. William Harvey discovered the circulation of blood in the early 1600s, overturning earlier theories, and the heart acts as a pump initiated by the sinoatrial node to circulate blood continuously through this system.
6.1 Digestion and Absorption (Chris Paine)
The small intestine has a structure that allows for both digestion and absorption of food. It has a folded inner wall and muscular outer layers that help move food along. The inner wall contains villi and microvilli that greatly increase the surface area for digestion and absorption. Enzymes in the small intestine digest macromolecules in food into smaller monomers. Absorption then occurs as these smaller molecules like glucose, amino acids, and fatty acids pass through the epithelial cells lining the villi into the bloodstream using various membrane transport processes. The liver plays an important role in processing absorbed glucose from the small intestine.
C ecology & conservation syllabus statements
The document discusses various topics relating to ecology and conservation, including species and communities, ecosystems, impacts of humans, conservation of biodiversity, population ecology, and nitrogen and phosphorus cycles. It provides essential ideas, understandings, applications, and skills for each topic. For example, for species and communities the essential idea is that community structure emerges from ecosystem properties, and understandings include how limiting factors affect species distribution and the unique role each species plays.
Academic honesty in ib
The document discusses academic honesty and misconduct in the International Baccalaureate (IB) program. It defines key terms like plagiarism, collusion, and exam misconduct. It notes that over half of investigated cases involve plagiarism while a quarter involve collusion. The document warns students about the consequences of getting caught cheating, like being banned from future exams or failing their diploma. It emphasizes that students are responsible for knowing what constitutes academic dishonesty and how to properly cite sources to avoid plagiarism.
Cas an introduction
This document provides information about CAS (Creativity, Activity, Service) which is an important component of the International Baccalaureate Diploma Programme. It explains that CAS involves learning through experience, personal development, and making a difference to others. Students must be involved in a variety of CAS experiences over 18 months including activities in creativity, activity, and service, as well as a CAS project and ongoing reflection. The document outlines examples of acceptable CAS experiences and provides guidance on documenting CAS in a portfolio using the learning outcomes framework.
11.2 muscle contraction
There are three main types of muscle tissue - skeletal, smooth, and cardiac. Muscle fibers are multinucleated cells formed from the fusion of individual embryonic muscle cells. Within each fiber are many parallel myofibrils composed of repeating sarcomere units. A sarcomere contains overlapping actin and myosin filaments. When an action potential reaches the neuromuscular junction, acetylcholine is released causing calcium ions to enter the fiber and allow the myosin heads to bind to actin, pulling the filaments together and contracting the muscle fiber. ATP provides energy to break the binding and reset the muscle for the next contraction.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
