Types of cells
Types of cellsExpertsmind IT Education Pvt Ltd. There are two main types of cells - prokaryotic cells that lack a nucleus and eukaryotic cells that have a nucleus. Kingdoms are divided based on whether cells are prokaryotic like Monera or eukaryotic like Protista, Fungi, Plantae, and Animalia. Unicellular organisms are in the kingdoms of Monera and Protista while multicellular organisms are in Fungi, Plantae, and Animalia.
Taxonomy
TaxonomyExpertsmind IT Education Pvt Ltd. The document discusses taxonomy and classification systems. It explains that binomial nomenclature is the scientific naming system developed by Carolus Linnaeus, using a two-part Latin name of genus and species. An example is provided of the full taxonomic classification of humans from the broadest kingdom to the specific species. Key terms like genus, species, and DNA are defined. A brief history of classification systems mentions Ernst Haeckel's original three kingdom system.
Osmosis
OsmosisExpertsmind IT Education Pvt Ltd. Osmosis is the diffusion of water across a selectively permeable membrane according to concentration gradients. Cells placed in hypotonic solutions will swell as water enters, while hypertonic solutions cause water to leave cells, shrinking them. Transport across the cell membrane is facilitated by carrier proteins that bind specific molecules and change shape to transport them either passively down gradients or actively against gradients using ATP. Cells take material in through endocytosis and release it through exocytosis using membrane-bound vesicles.
Nitrogen fixations 
Nitrogen fixations Expertsmind IT Education Pvt Ltd. The document discusses nitrogen fixation, which is the process by which nitrogen in the atmosphere is converted into a form that can be used by living things. It then provides details about the general characteristics of bacteria, including that they are single-celled organisms without organelles, have a cell wall composed of peptidoglycan, can reproduce through binary fission, and can perform both aerobic and anaerobic respiration. Finally, it lists 13 biological importance of bacteria, such as their role in producing antibiotics, decomposing waste, and processing foods like cheese and yogurt.
Mitosis 
Mitosis Expertsmind IT Education Pvt Ltd. 1. Mitosis involves cell division for growth, healing, and asexual reproduction where one diploid cell divides into two identical diploid daughter cells.
2. The main stages of mitosis are prophase, metaphase, anaphase and telophase where chromosomes condense and align before separating and distributing into two new daughter cells.
3. Meiosis involves two cell divisions that result in four haploid cells from one original diploid cell. The main stages are similar to mitosis but with additional processes like independent assortment and crossing over during prophase I and a second division to separate sister chromatids.
Membrane biology
Membrane biologyExpertsmind IT Education Pvt Ltd. The plasma membrane separates the interior of the cell from the outside environment. It is a phospholipid bilayer with embedded proteins. The fluid mosaic model describes the plasma membrane structure, with hydrophobic lipid tails facing the interior and hydrophilic heads facing the exterior. Membrane proteins have various functions like transport, receiving signals, and acting as enzymes. The plasma membrane is selectively permeable, allowing small uncharged molecules to pass through by passive or active transport mechanisms.
Kingdom monera
Kingdom moneraExpertsmind IT Education Pvt Ltd. Monera is a kingdom composed solely of prokaryotic organisms like bacteria and cyanobacteria. Bacteria can exist as single cells, filaments, or colonies, and can be aerobic or anaerobic, autotrophic or heterotrophic. Other groups in the kingdom include cyanobacteria, which can perform photosynthesis, and eubacteria, which rely on organic carbon sources. Archaebacteria are the most ancient group and differ so greatly from other Monera that they may constitute their own kingdom.
Introduction to cell
Introduction to cellExpertsmind IT Education Pvt Ltd. The document discusses the structure and function of prokaryotic cells. Prokaryotic cells are much smaller and simpler than eukaryotic cells, lacking organelles like the nucleus and mitochondria. The basic structure of a prokaryotic cell includes an outer cell wall and cytoplasmic membrane, cytoplasm containing ribosomes and other inclusions, and sometimes additional structures like flagella, pili, or plasmids. The cell wall provides shape and rigidity while the membrane is semipermeable and controls movement of molecules in and out. Ribosomes perform protein synthesis and mesosomes are involved in respiration.
Homeostasis
HomeostasisExpertsmind IT Education Pvt Ltd. Homeostasis refers to the maintenance of a stable internal environment in an organism. Most homeostatic mechanisms operate through negative feedback loops. A negative feedback loop has components that sense a deviation from the optimal range and trigger responses that act to reverse the deviation and restore homeostasis. An example is the regulation of body temperature through sweating or shivering in response to temperature changes.
Growth & development
Growth & developmentExpertsmind IT Education Pvt Ltd. In multi-celled organisms, growth occurs through the production of new cells, which increases the total number of cells and total surface area to volume ratio. Metamorphosis in animal development allows for different forms adapted to different environments and food sources over an organism's lifespan. This provides advantages like access to new resources and habitats as the organism matures.
General biology
General biologyExpertsmind IT Education Pvt Ltd. Biology is the science of life and living organisms, including their structure, function, growth, origin, and distribution. It includes subdisciplines like microbiology, botany, zoology, anatomy, physiology, cell biology, biochemistry, genetics, and molecular biology. Biology seeks to understand life at different scales, from molecules to cells to tissues to whole organisms, and examines the chemistry and physics underlying living things. Key concepts that guide biologists include different levels of biological organization and the idea that the difference between living and non-living things is one of degree rather than kind.

Physics Problem | Sample Assignment | www.expertsmind.com Question: A game that friends and I try to play to guess how long it takes a ball to fall to the bottom of a cone and how many revolutions around the cone it will take. I do not have a lot of physics experience, but I was under the impression that if we knew certain constants such as: the diameter and height of the cone, the mass of the ball, the velocity of the ball as it falls into the cone, the angle of the side of the cone, and the usual constants for gravity and surface friction - that we should be able to know the exact time the ball will fall to the bottom. We should also be able to know the distance the ball travelled going around the cone before hitting the bottom. Sadly, I am not quite able to work out how to guess either the time or distance. What are the formulas to calculate such things? Any suggestions? Since ball is falling from circumference of Cone at poison M (RED BALL) with initial velocity v’. It is given that h is the height of the Cone and q is the angle between surface and slant height of the cone. Its look like as
- 2. Thus Height sin q = Hypotensis h => sin q = slant height => slant height = h cos ec q At any point in the path
- 3. Thus we throw a ball from point M with initial velocity v. then v ' = vx i + v 'y j ' Where v x and v 'y are velocities along x and y- direction both. ' Thus v ' = v 'cos(f - q )i + v 'sin(f - q ) j Since motion starts at M point which is h height from the base, therefore position of the Ball after t time x = v 'cos(f - q )t 1 2 y - h = v 'sin(f - q )t - gt 2 Eliminating t from these two equations g y - h = x tan(f - q ) - x2 2v ' cos (f - q ) 2 2 This is the path of the ball. Now we will estimate the time travel by ball from M to P via N. 2v 'y 2v 'sin(f - q ) Thus total time travel T = Time travel by ball from M to P = = g g
- 4. And using this time, maximum travel by ball 2v 'cos(f - q ).v 'sin(f - q ) R = v 'cos(f - q )T = g 2v '2 cos(f - q ).sin(f - q ) v '2 sin 2(f - q ) = = g g
