General Science Questions

"Humidity" refers to the presence of water vapor in the atmosphere. It is measured in either relative terms (relative humidity) or absolute terms (dewpoint temperature).Humidity indicates the likelihood for precipitation, dew, or fog to be present.

Garbage burning is common in rural areas, but it poses health concerns and hazards to the environment. It especially affects people with sensitive respiratory systems, as well as children and the elderly.

Benefits ::

• It produces methane that can be used like natural gas.
• It partially addresses the solid waste disposal problem.
• It provides biomass energy.

Hence, it creates more space for farming is not the benefit of the burning garbage.

PTH - Parathyroid hormone which balances calcium levels if they are low.

It is the Interphase, which occurs after cytokinesis. And in interphase we have 3 stages likely G1, G2 and S phase. After cytokinesis we get G1 phase.

The ozone gas present in the atmosphere absorb ultraviolet radiation. It is spread as a ozone layer throughout the stratosphere.

Most stars are at main sequence point in their life cycles.

A chemical reaction in which involves the absorption of heat from the environment is called a Endothermic reaction. 

Examples : Dissolving ammonium chloride in water, photosynthesis, melting ice cubes, mixing of potassium chloride with water,...

In the contrast, chemical reactions involving release of heat are known as exothermic reactions.

Examples : Combustion, coal is burnt, mix of CaO with water,...
