How does an earthworm move explain briefly
  • 2 answers

Yogita Ingle 2 hours ago

Earthworms are small worms which can move easily on hard and slippery surfaces. Earthworms move with help of tiny, stiff hair-like projections called bristles. Earthworms move forward by repeated contractions and relaxations of their muscles in the skin. A slimy substance secreted by the earthworm helps in its movement.

Characteristics of living things
  • 2 answers

Gaurav Seth 2 days ago

Living' means a thing which can grow, reproduce and has the cellular organisation. A living thing is also aware of its surrounding. These unique characteristics make a living thing different from non-living things.

Four defining features of life forms are:

(a) Growth: It is the permanent increase in cell number and size of the organism. It involves cell division. Dead organisms do not grow.

(b) Reproduction: The ability of an organism to produce progeny, more or less similar to itself, is called reproduction. Two main modes of reproduction found in organisms are the asexual reproduction and sexual reproduction.

(c) Metabolism : The sum total of all the chemical reactions occurring in the body of an organism is metabolism. No non-living object exhibits metabolism.

(d) Cellular organisation: The body of all living beings consists of one or many cells, therefore cell is known as the fundamental unit of life.

Explain how air helps water-cycle.
  • 1 answers

Yogita Ingle 5 days, 3 hours ago

The cyclic movement of water from the atmosphere to the Earth and back to the atmosphere through various processes is called as water cycle.

Different steps of water cycle include evaporation, transpiration, condensation, precipitation and surface run-off.

Evaporation - The water present on the surface of oceans evaporates by the sun’s heat. This process of conversion of water from liquid state to vapour state is called evaporation. Evaporation also takes place from wet clothes, fields, ponds, lakes and rivers.

Transpiration - Plants take in water from the soil to prepare their own food and also for other life processes. They release excess water into air in the form of water vapour by the process of transpiration.

Condensation - The evaporated water is carried away by warm air. As the warm air moves higher from the surface of the Earth, it starts to cool down. This water vapour condenses to form tiny water droplets which float in air to form clouds or fog.

Precipitation - All these droplets collect to form bigger drops of water. Bigger water drops come down ads rain by the process of precipitation. If the air is too cold, the water drops can become snow or hail and may settle on the top of a mountain. When these snow or hail melts, they can become part of a river or a stream.

Surface run-off – Some amount of rain water is absorbed by the soil and settles down as ground water. Most of the rain water flows down the hills and mountains to collect into rivers, lakes or streams. Rain also washes away the topmost layer of the soil into water bodies.
