Yogita Ingle 6 years, 4 months ago

Vitro fertilization (IVF):

It is a method in which ovum collected from a female’s body is allowed to fuse with sperm collected from a male’s body in an external medium or outside the body of the female.
The zygote so developed is allowed to grow in vitro (i.e.in glass) for about a week and then implanted in the female’s uterus where it further develops as a normal embryo.
A baby born of this technique is often called a ‘test tube’ baby.

Why are forest fires more likely in the hot, dry season than in the rainy and cold season

Posted by K Sidharth 6 years, 4 months ago

Meghna Thapar 6 years, 1 month ago

Temperature affects the sparking of forest fires. The sticks, trees and underbrush on the ground receive radiant heat from the sun, which heats and dries potential fuels. Warmer temperatures allow for fuels to ignite and burn faster, adding to the rate at which a wildfire spreads. That is why, forest fires more likely in the hot, dry season than in the rainy and cold season

Why do we blink our eyes?

Posted by Shreya Kumari Gupta 6 years, 4 months ago

CBSE > Class 08 > Science

1 answers

Radhika Sharma✌️✌️ 6 years, 4 months ago

Every time you blink, your eyelids spread a cocktail of oils and mucous secretions across the surface of the eye to keep your globes from drying out. Blinking also keeps eyes safe from potentially damaging stimuli, such as bright lights and foreign bodies like dust.

Explain divide and rule policy

Posted by Shreya Kumari Gupta 6 years, 4 months ago

CBSE > Class 08 > Social Science

1 answers

Yogita Ingle 6 years, 4 months ago

"Divide and Rule" policy is the policy under which the rulers divide people in small groups, so they cannot rebel against the state. These policies were followed by many European states in order to colonize developing or underdeveloped countries. The British used the same policy in India.

The East India Company used the "Divide and Rule" in order to segregate the Indians on the basis of economic, religious, social and political differences. They knew that India was full of resources and they wanted to limit the benefit to themselves. Hence, they divided the kings/princes of states by imposing policies that only protected the rulers, not the people.

As a result, the kings/princes handed over the states to the British as gratitude. They signed policies by which the British gained power in their state. The British started by establishing the trading company in India but directly ruled over it from 1858-1947.

Human heart

Posted by Kavita Kavita 6 years, 4 months ago

CBSE > Class 08 > Science

1 answers

Meghna Thapar 6 years, 2 months ago

The heart is roughly triangular in shape. It has four compartments called chambers inside it. The upper two chambers of the heart are called atria and the lower two chambers are called ventricles. The atria receive blood from the two main veins. The left atrium is connected to the left ventricle through a valve V1 and the right atrium is connected to the right ventricle through another valve V2. These valves prevent the backflow of blood into atria when the ventricles contract to pump blood out of the heart to the rest of the body because when the ventricles contract, the valves V1 and V2 close automatically so that the blood may not go back into the atria. The job of heart is to pump blood around our body. All the atria and ventricles of the heart contract and relax at appropriate times and make the heart behave like a pump. A sheath of tissue called pericardium protects the muscular heart.

Dineshkumar Seenivasan 6 years, 4 months ago

shifting cultivation is also called as slash and burn culture. These type of cultivation mostly takes place on amazon river basin. It means that the farmer cuts the trees in a particular land and burns thus allowing the minerals to settle down in the soil to make the soil more fertile. few years later after the soil has lost its soil fertility the farmer moves to another plot if land does the same process there. Again when that soil loses its soil fertility he well come back to the plot or will go to another new plot and do the same process.

To be clear, the potato is not, in and of itself, an energy source. What the potato does is simply help conduct electricity by acting as what's called a salt-bridge between the the two metals, allowing the electron current to move freely across the wire to create electricity.
