The interaction between the biosphere and hydrosphere is that the hydrosphere provides water for the biosphere to function, grow, and live. Animals (biosphere), fish (biosphere) need water (hydrosphere) to live and swim.
Answer:
Coal, natural gas, and petroleum are all fossil fuels that formed under similar conditions. Today, petroleum is found in vast underground reservoirs where ancient seas were located. Petroleum reservoirs can be found beneath land or the ocean floor. Their crude oil is extracted with giant drilling machines.

The sequence of amino acid in polypeptide is dictated by the codons in the messenger RNA molecules from which polypeptide was translated. The sequence of codons in the mRNA was in turn dictated by the sequence of codons in the DNA from which the mRNA was transcribed. The amino acids are linked covalently by peptide bonds.
Answer:
B. the action of microRNAs that block translation of specific mRNA molecule
C. the action of RNA–protein complexes that degrade the regulatory proteins responsible for initiating transcription.
Explanation:
RNA interference occurs what RNA prevent the translation of some gene this is done by neutralizing target mRNA molecule. It suppresses the effects of some desires genes through its action.
MicroRNA and small interfering RNA (miRNA and siRNA) are the major RNA that controls interference. siRNA and miRNA prevent translation by directing some enzmes complexes to denature the mRNA molecule needed for translation. They intiate post transcriptional splicing.
RNA interference is found in eukaryote and some animals and its initiated by enzyme Dicer that inhibits translation by degrading the enzymes action.
Substitution:
7y=1-10x
-5x-7(1-10x)=4
X=1
-5(1-7y)=4
Y=-9/7
Therefore, your answer would be {1,-9/7}
