Answer:
They consist mainly of iron-nickel metal with small amounts of sulphide and carbide minerals. During the decay of radioactive elements in the early history of the solar system, many asteroids melted and the iron they contained, being dense, sank to the centre to form a metallic core.

Answer:
UGGCUCCAA
Explanation:
Basically when you transcribe DNA into mRNA, you find the complementing base pair, for example if G is written in the DNA, the mRNA would show C, and if an A was in the DNA, a U would be shown. It is NOT THYMINE in RNA!! This changes to Uracil in RNA, and that is VERY important. The reason why it is flipped is because of the tRNA. So 3 mRNA nucleotides make a codon, and the tRNA are also in sets of 3, but are called anticodons. The tRNA is complementary to the mRNA strand, AKA the same as the DNA strand except with Uracil instead of Thymine. This is because Thymine breaks down in the presence of Oxygen and so is replaced by Uracil.
Answer:
The correct answer is - Protein hormones are synthesized on free ribosomes (false).
Explanation:
The majority of the hormones that are produced from endocrine glands are produced are steroids however some of the hormones are made up of peptide or proteins.
Protein hormone synthesis uses RNA, is a copy of the gene for this hormone, this is packaged into vesicles with the help of ER and Golgi bodies for movement through the cell and reaches to its target cell by traveling through the bloodstream. mRNA is transcribed from DNA in order to produce protein. These hormones are produced according to the mRNA coding from amino acids in the cell.
