Mine shows an activation requirement or else an expiration. Can anyone help?
If anyone has it. Upload it?
please provide if you have one
Subject is internet and intranet IOE. Any help you can provide? What to write? Code or about AJAX? If code, can you share simple code to make a web app using xml and js?

An ecosystem is a community of living organisms in conjunction with the non-living components of their environment (things like air, wider and mineral soil), interacting as a system. Ecosystem is a natural unit which consists of biotic communities and their abiotic environment. It is also Basic functional unit in ecology. Energy, water, nitrogen and soil minerals are other essential abiotic components of an ecosystem. Ecosystem are controlled both by external and internal factors. External factors such as climate, parent material that forms the soil, typography, etc. and internal factors include disturbance, succession and the types of species present.
Characteristics of Ecosystem:
i) Biotic component: producer (green plants), consumers (animals), decomposers (microorganisms)
ii) Abiotic component: Air, water, soil
iii) Energy flow: Sun is the main source of energy
iv) Matter
v) Interrelationship
vi) Biological integration
vii) Flexibility
viii) Ecological regulation
ix) Smallest unit of biosphere
x) An open system with a continuous, but variable influx and loss of materials and energy.

Water pollution is defined as the presence of various types of impurities that tends to degrade its quality and either constitutes a health hazardRead more
Accumulation of any substances in the air in the sufficient concentration to effect man, animals, vegetation or other materials is called air pollution.
Water pollution is defined as the presence of various types of impurities that tends to degrade its quality and either constitutes a health hazard or otherwise decrease the utility of water.
Sources of water pollution
Natural: Soil erosion, solutions of mineral in water, rain water, storms, earthquake. seawater intrusion, dust/dirt falling from atmosphere, deposition of animal wastes and fallen leaves, etc.
Man made: Due to agriculture, sewage, wastes, industry
Mitigation measures of water pollution

Emission of Green house gases is the main cause of climate change. Green house gases are carbon dioxide, methane, nitrous oxide, fluorinated gas, etc. These gases are produced primarily through the burning of fossil fuels (oil, natural gas, and coal), solid waste and trees and wood products but also deforestation and soil degradation add carbon dioxide to the atmosphere and re-growth of forest can be supplemented b y conserving them. Following points describe national parks and conservation area important in Nepal as an effective strategy to reduce green house gas emission:
The ability to perform work is said to be energy of a system. Alternatively, energy of a system can be defined as capacity of system to exert force for a certain interval. If a system has high energy content, it can provide higher magnitude of force for longer interval of time. Exchange of energy acRead more
The ability to perform work is said to be energy of a system. Alternatively, energy of a system can be defined as capacity of system to exert force for a certain interval. If a system has high energy content, it can provide higher magnitude of force for longer interval of time.
Exchange of energy across the boundary of a system due to the intensive property difference between system and surrounding is said to be energy transfer. Energy transfer occurs as heat transfer or work transfer.
A form of energy which constitutes total energy of a system, remains within the system boundary as inherent property of a system is said to be stored energy. Internal energy, potential energy, kinetic energy,etc., are examples of stored energy. Stored energy has unique value for each equilibrium state and is independent of path. Hence, it is a thermodynamic property.
A form of energy that can cross the boundary of a system during thermodynamic process is said to be transient energy. Heat transfer and work transfer are examples of transient energy. Transient energy is a a dynamic form of energy and do not have unique value for each equilibrium state. It depends on properties of system as well as properties of surrounding. It is dependent on path. Thus, it is not thermodynamic property.
