Alexander Sergeyevich Pushkin (/'pUSkIn/; Russian: Aleksandr Sergeevich Pushkin, tr. Aleksandr Sergeyevich Pushkin; IPA: [aljI'ksandr sjI'rgjejIvjItc 'puskjIn]; 6 June [O.S. 26 May] 1799 - 10 February [O.S. 29 January] 1837) was a Russian author of the Romantic era who is considered by many to be the greatest Russian poet and the founder of modern Russian literature. Pushkin was born into Russian nobility in Moscow. His matrilineal great grandfather was Abram Gannibal, who was brought over as a slave from what is now Cameroon. Pushkin published his first poem at the age of fifteen, and was widely recognized by the literary establishment by the time of his graduation from the Tsarskoye Selo Lyceum. While under the strict surveillance of the Tsar's political police and unable to publish, Pushkin wrote his most famous play, the drama Boris Godunov. His novel in verse, Eugene Onegin, was serialized between 1825 and 1832. Notoriously touchy about his honour, Pushkin fought as many as twenty-nine duels, and was fatally wounded in such an encounter with Georges-Charles de Heeckeren d'Anthes. Pushkin had accused D'Anthes, a French officer serving with the Chevalier Guard Regiment of attempting to seduce the poet's wife, Natalya Pushkina.

Earth processes have not changed over time. The way things happen now is the same way things happened in the past. Mountains grow and mountains slowly wear away. The same process is at work the same as it was billions of years ago. As the environment changes, living creatures adapt. They change over time. Some organisms may not be able to adapt. They become extinct. Becoming extinct means they die out completely. Some geologists study the history of the Earth. They want to learn about Earths past. They use clues from rocks and fossils. They use these clues to make sense of events. The goal is to place things in the order they happened. They also want to know how long it took for those events to happen.

Question: "What happens when some living organism do not adapt to changes in the environment?"

Answer: "Extinction"

Response: yes

Plants also detect the daily cycle of light and darkness. Do you know how plants respond to these changes? Some plants open their leaves during the day. It is during these hours the plant can collect sunlight. At night, the plant closes its leaves to prevent water loss. Many plants respond to the change in the length of the day. As days grow shorter, some plants respond by going dormant. Dormant is when a plant suspends its growth. It does this in order to survive. Shorter days signal the coming of winter. Winter in most areas means extreme cold. It is also very dry in the winter months. As winter approaches, some plants respond by their leaves changing color. After the change in color, they fall off. This dormancy period helps trees. It allows them to survive the cold and dry winter. Plants only want to grow when conditions are right.

Question: "Does a plant suspend its growth when days get longer, or when days get shorter?"

Answer: "When days get shorter"

Response: yes

Density is also an important physical property of matter. The concept of density combines what we know about an objects mass and volume. Density reflects how closely packed the particles of matter are. When particles are packed together more tightly, matter is more dense. Differences in density of matter explain many phenomena. It explains why helium balloons rise. It explains why currents such as the Gulf Stream flow through the oceans. It explains why some things float in or sink. You can see this in action by pouring vegetable oil into water. You can see a colorful demonstration in this video.

Question: "What does density tell?"

Answer: "The area of subjects"

Response:
no
