________ provides scientists a systematic easy way of studying organisms.

________ tissues provides mechanical support to organs.

Assertion : Classification is necessary to study all living organisms. Reason : In classification, individuals are grouped into categories.

The first systematic approach to the classification of living organisms was done by Carl Linnaeus.

Assertion : Systematics is defined as the science of diversity of organisms in evolutionary context. Reason : Systematics include interrelationship between organisms.

____is a natural science concerned with study of life and living organisms

Gravitational waves: Waves are created on the surface of water when we drop a stone into it. Similarly you must have seen the waves generated on a strintg when both its ends are held in hand and it is shaken. Light is also a type of wave called the electromagnetic wave. Gamma rays, X-rays, ultraviolet rays, infrared rays, microwave and radio waves are all different types of electromagnetic waves. Astronomical objects emit these waves and we receive them using our instruments. All our knowledge about the universe has been obtained through these waves. Gravitational waves are a very different type of waves. They have been called the waves on the fabric of space-time. Insteine predicted their existence in 1916. These waves are very weak and it is very difficult to detect them. Scientists have constructed extremely sensitive instruments to detect the gravitational waves emitted by astronomical sources. Among these, LIGO (Laser Interferometrc Gravitational Wave Observatory) is the prominent one. Exactly after hundred years of their prediction, scientists detected these waves coming from an astronomical source. Indian scientist have contributed significantly in this discovery. This discovery has opened a new path to obtain information about the Universe. Is it easy to detect Gravitational waves?

The branch of science which studies the ineractions among organisms and between organisms and physical environment is called as
