GaryK [48]

The answer here is D, and it's kind of obvious. But you probably already knew the answer and are just doing this for piece of mind.

Explanation: Just the fact that we don't know whether or not there even is extraterrestrial life rules out every other answer, without even needing to go in depth.

(Okay, I read your question completely wrong, it's asking for which one of these has been solved isn't it?)

This is tough because all of these other than D have been figured out. Go with the methane atmosphere then.

How does the sun power the carbon cycle

hoa [83]

Answer:

The sun takes an integral role in the photosynthesis stage of the Carbon Cycle. Photosynthesis refers to the process by which plants take in carbon dioxide and water (the products of respiration), and convert it to oxygen, powered by the energy of the sun.

Nady [450]

Answer:

Valine-Leucine-Proline-Lysine-Histidine

Explanation:

The central dogma of biology is the process by which DNA is used to synthesize RNA and subsequently amino acid sequence (PROTEIN). The processes of transcription and translation is used in gene expression. Transcription is the process whereby the information encoded in a DNA molecule is used to synthesize a mRNA molecule. Transcription is catalyzed by RNA polymerase enzyme, which uses complementary base pairing rule i.e Adenine(A)-Thymine(T), Guanine(G)-Cytosine(C) pairing.

N.B: Thymine is replaced by Uracil in the mRNA

For the above DNA sequence: CAC GAC GGA TTC GTA, the mRNA sequence will be: GUG CUG CCU AAG CAU

Translation is the second process of gene expression which involves the synthesis of an amino acid sequence from an mRNA molecule. The mRNA is read in a group of three nucleotides called CODON. Each codon specifies an amino acid (see attached image for genetic code)

Based on the attached genetic code, an mRNA sequence: GUG CUG CCU AAG CAU will encode an amino acid sequence: Valine(Val) - Leucine (Leu) -Proline (Pro) -Lysine (Lys) - Histidine (His).

GUG specifies Valine amino acid

CUG specifies Leucine amino acid

CCU specifies Proline amino acid

AAG specifies Lysine amino acid

CAU specifies Histidine amino acid
