Answer:
ATP
Explanation:
Adenosine triphosphate, commonly known as ATP, is the chemical molecule that stores and provides/releases energy in cells. ATP is needed by the cells of every living organism and is obtained via a process called CELLULAR RESPIRATION.
Cellular respiration is the process whereby cells breakdown food molecules (sugar) to synthesize energy storing molecules called ATP. Hence, in every tube where cellular respiration is occuring, ATP is the produced molecule that provides energy.
Answer:
A molecule of mRNA is formed.
Explanation:
Translation is the second process that occurs in gene expression. It is the process by which the information encoded in the mRNA transcript is used to synthesize a protein.
The mRNA nucleotide sequence is read in a group of three nucleotides called CODON. Each codon specifies an amino acid. Translation, which occurs in the ribosomes (cytoplasm), reads the codon with an anticodon using the complementary base pairing rule i.e. A-U, G-C. This means that a CODON-ANTICODON pairs.
The anticodon carries a corresponding amino acid to the polypeptide sequence. A peptide bond is formed when two amino acids joins together in a condensation reaction.
Note: A molecule of mRNA is formed during transcription

Answer: A: Its fertile oases enabled farmers to grow enough food for themselves and for sale.
Explanation: The Arabia region is a region located within the Arabian desert. A desert is an area of extreme heat, often dry weather condition with barren lands that cannot support agriculture and food production. An oases on the other hand is a region of luscious, cultivate-able land within a desert.
Food is one of the most important basic needs of man and hardly can anyone survive without food for more than twenty days. Hence, the presence of oases within the otherwise dry environment of the Arabia region is a major protection against death from hunger.
Taking a closer look at other options, none of them guarantees food supply and income to the Arabia region unlike food production in oases. Hence, the fertile oases is really the most important factor that serves as protection in the region's history.
Correct option: A
