In the metric system, the prefix 'mega-' denotes a factor of 10^6, which is one million.

Sulphur shower : In the month of May, on hills the  yellow Pollen grains of Pinus Plants are Produced in lot of number and are scattered in air.

Acclimatization is the development of a favourable morphological and physiological response to a change In environment.

The organisms that use external heat to maintain their body temperature are termed as ectotherms while those maintaining their body temperature using the metabolic heat are termed as endotherms (mammals and aves). Among the given options, Blue jay (aves) is endotherms. 

At the molecular level even living things are fundamentally made up of all the elements that make non-living matter. There have been attempts to make these molecules and their integration to create life by scientists but none of them has been successful yet. Hence, it is often believed that there is a vital force that can not be created by us that gives organisms characteristics of life. 

Biotic potential refers to the maximum reproductive capacity of an organism under optimal environmental conditions. It works in opposition to environmental resistance, which limits population growth based on resource availability and environmental constraints.

An object appears red because it reflects (scatters) red wavelengths of light and absorbs the other wavelengths in the visible spectrum.

Environmental education is inherently interdisciplinary because it integrates concepts from biology, chemistry, geography, sociology, and economics to address complex environmental issues.

UNCED refers to the United Nations Conference on Environment and Development, also known as the Earth Summit held in Rio de Janeiro in 1992.

Animals with constant body temperature are called homoootherms. They have insulating coat to check the loss of body heat. This coat consists of hair in most mammals, blubber (subcutaneous fat) in whales and perspiration cools down the body of these animals when required.These are also termed endothermic as they regulate their body temperature by physio;logical means and maintain more or less constant internal temperature. Poililotherms are cold-blooded animals which are unable to regulate their body temperature which changes with change in temperature of environment e.g. fish, frog, lizard. They are also called as ectothems.
