| Answer» <p>How does the water get into the atmosphere?Only a tiny fraction of Earth’s water is in the atmosphere at any one time. It doesn’t stay up there for long and there are several different ways that it can get up there!</p><p>Heat from the Sun causes water to evaporate from the surface of lakes and oceans. This turns the liquid water into water vapor in the atmosphere.</p><p>Plants, too, help water get into the atmosphere through a process called transpiration! After absorbing water from the ground, plants “sweat” water vapor through their leaves to stay cool.</p><p>Water can also get into the atmosphere from snow and ice. Instead of melting, some frozen water changes into water vapor gas and goes into the atmosphere through a process called sublimation.</p> | |

SECTION-Csex of a new born individual in some species is largely determined genetically while in others itis otherwise." Give three different examples to justify this statement. |
| Answer» <p>(i) In some of the animals, sex determination is controlled by the environmental factors.(ii) In some reptiles, the temperature at which the fertilised egg is incubated before hatching, plays a role in sex determination of the offspring.For example: In a turtle, high incubation temperature leads to the development of female offsprings. Whereas in case of a lizard (Agama agama), high incubation temperature leads to the development of male offsprings.(iii) In case of some animals like snails, sex can be changed by individuals. It is not determined genetically.</p> | |
