Answer: 23 hrs 56 min

Explanation: Because the earth rotates a full rotation in 24 hrs so the star will be in the same spot just before the full rotation is done.

one can measure time by the fractional distance a star has gone in its full circle around the sky. This is best done for stars that never set, stars near the north celestial pole.

Que signifie ADN et comment on le prouve?
irakobra [83]

Answer:

<h3>Qu'est-ce que l'ADN ?</h3>

L'ADN (acide désoxyribonucléique) est un type d'acide nucléique qui se distingue par le stockage de l'information génétique de la grande majorité des êtres vivants. Cette molécule est formée de nucléotides et a généralement la forme d'une double hélice.

Il est nécessaire de prélever des échantillons de certains fluides corporels qui peuvent être du sang, de la salive, des ongles, des cheveux ou du sperme. À l'aide de techniques de laboratoire sophistiquées, l'ADN des échantillons est isolé, puis une cartographie est effectuée, ce qui est fait par des équipements appelés "Séquenceurs d'ADN".

Pour le prouver, normalement le rapport d'un examen ADN apporte quels gènes et chromosomes ont été étudiés et l'analyse du généticien à leur sujet. Les résultats sont présentés dans des rapports simples et clairs. Dans les examens de paternité, le résultat est toujours comparatif.

J'espère t'avoir aidé, bonnes études !

  • Possession of a Boating Safety Education Identification Card issued by the FWC.
