The lungs deliver oxygen and remove carbon dioxide from your blood in a process called gas exchange. Gas exchange happens in the capillaries surrounding the alveoli, where the oxygen that is breathed in enters the circulatory system and carbon dioxide in the blood is released to the lungs and then breathed out.

The children hear the sound of wind blowing, the trees and a variety of animals, birds and insects while crossing a forest. At some places, the forest is so thick that even sunlight does not pass through. When it is very silent there, we can only hear the sounds of different birds and other creatures.

ANSWER

EX 1 :- Read the given passage and answer the questions that follow: 6 marks Small improvements can lead to big changes. A few flowers can change the look of a room. The efficiency of a factory, for instance, depends upon an infinite number of operations, performed properly from day to day. ( para 1) Abraham Maslow, the well known psychologist, mentioned with admiration the case of a young man who spent several years in Mexico digging deep wells to provide clean drinking water to the villages. He managed to dig only three wells, and had to spend enormous amount of time teaching the villagers to use pure water in place of contaminated water. There may have been only three wells but they gave the engineer a great feeling of achievement. ( para 2) Charles Darwin has shown that, given enough time, small and gradual causes can produce large and radical changes. His last book was in fact on earthworms. He was preoccupied with the theme for forty years. He had shown that on every acre of Chall, hills near Down, worms brought up eighteen tons of earth annually. What a stupendous achievement for the small and insignificant earthworm! ( para 3)

Who are maternal and paternal relatives

Posted by Manjima Jayakumar 5 years, 8 months ago

CBSE > Class 04 > EVS

Meghna Thapar 5 years, 7 months ago

A 'maternal relation', therefore, is a relation through the mother (for example, maternal grandmother means the grandmother who is the mother's mother). Likewise, a 'paternal relation' is a relation through the father (a paternal uncle is the father's brother). The definition of maternal is something related to or characteristic of a mother, such as motherly instincts or relatives from a mother's side of the family. An example of maternal is rocking a baby to sleep. An example of maternal is your grandmother on your mother's side.

Meghna Thapar 5 years, 7 months ago

A woman yearning for a child asks a witch for advice, and is presented with a barleycorn which she is told to go home and plant (in the first English translation of 1847 by Mary Howitt, the tale opens with a beggar woman giving a peasant's wife a barleycorn in exchange for food). After the barleycorn is planted and sprouts, a tiny girl, Thumbelina (Tommelise), emerges from its flower. One night, Thumbelina, asleep in her walnut-shell cradle, is carried off by a toad who wants her as a bride for her son.
