Adn-ul |
|
Acidul deoxiribonucleic (adn pe scurt) este materialul genetic al organismelor celulare si al celor mai multi virusi. adn-ul poarta informatiile necesare sintetizarii directe a proteinelor si pentru replicare. Sinteza proteinelor este producerea de proteine necesare celulei sau virusilor pentru activitatiile acestora sau pentru dezvoltare.
Replicarea este procesul prin care adn-ul se copiaza pe sine insusi pentru fiecare celula descendenta sau virus, pasadn informatii despre sinteza proteinelor. In cele mai multe organisme celulare adn-ul este organizat ca si cromozomi localizati in nucleul celulei. .

Maddness |
|
In order for one to fully understand the term “madness”, we first need to show what the word really means. After looking through numerous definitions and asking others on their views, the definition from the oxford dictionary seemed to sum up the general thoughts of my family and friends.
“…a departure from what is normal or accepted, a moral or mental lapse.” These views might differ from person to person as morals and ideas change and societies accept different behaviors. Thus I believe “madness” generally changes it’s true meaning according to different societies perceptions. . Maddness |

Importanta proteinelor |
|
Proteinele reprezinta un numar mare de compusi organici constituiti din aminoacizi uniti prin legaturi peptidice, ce formeaza organisme vi si sunt esentiale pentru functionarea lor. Descoperite in 1838, proteinele sunt acum recunoscute ca fiind principala componenta a celulelor vii, insemnand mai mult de 50 la suta din greutatea “uscata” a animalelor. Cuvantul proteina vine din grecescul proteinos care inseamna principal..........................

Celula |
| Celulele – baza chimica a vietii – sunt “caramizile” din care este construit organismul pluricelular. Materialele chimice care alcatuiesc celule au drept unitati moleculele. Moleculele sunt grupari de atomi. Atomii sunt legati prin forte chimice. Dintre elementele chimice, carbonul este nelipsit din substantele organice. Compusii carbonului sunt numerosi si cu proprietati chimice foarte variate. Pentru viata sunt importante legaturile C-H ce pot constitui adevarate rezerve de energie. Energia este pusa in libertate prin procese de oxidare si reducere............. Celula, carbon, molecule, bacteriana, bacteriile, vegetala, animala, membrana, citoplasma, adn, amiba, parameci |

Cleopatra |
|
Cleopatra Vll was born in 69 BC, in Alexandria, Egypt. Despite what people say today, that she was glamorous and beautiful, she was far from it.
She is shown on ancient coins with a long hooked nose and masculine features. Although she was not beautiful she was clearly a very seductive woman, and she used this to further Egypt politically. She had a beautiful musical voice. It is also said that she was highly intelligent. She spoke nine different languages, and she was the first Ptolemy pharaoh who could actually spoke Egyptian. She ascended the Egyptian throne after her father, Ptolemy Xll Auletes died in 51 BC. Cleopatra which was seventeen at the time and her brother Ptolemy Xlll, which was twelve, were married because of the terms of her fathers will. They then ruled Egypt together. In the third year of their reign Ptolemy’s advisers told him that he should rule Egypt by himself. So, because of this he drove Cleopatra into exile. Cleopatra then escaped to Syria. She then returned with an army. Ptolemy sent an army to meet with her. At this point, Julius Caesar of Rome arrived in pursuit of an enemy, who was seeking help from Ptolemy. Cleopatra had to roll herself up in a rug so that she wouldn’t get killed while entering Egypt. If she hadn’t hidden herself she would have been killed. When she unrolled herself in front of Caesar he fell in love with her right away.Caesar had to choose which of the Egyptian rulers to help keep the throne. Of course he chose Cleopatra. He then became Cleopatra’s lover. In 47 BC Ptolemy Xlll drowned in the Nile while trying to escape, and Caesar then restored Cleopatra to her throne. . Cleopatra |
