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.
Answer:
UAC, and it encodes for the aminoacid Tyrosine.
Explanation:
Uracile pairs with Adenine via two hdrogen bonds, and Cytosine matches with Guanine with three hydrogen bonds in RNA molecules. In DNA molecules, there is not uracile, they contain Thymine instead, so Adenine pairs with Thymine by two hydrogen bonds.
The cell cycle is composed of interphase (G₁, S, and G₂ phases), followed by the mitotic phase (mitosis and cytokinesis), and G₀ phase.
the membrane receptors are activated when a certain chemical attaches itself to the receptor.
