Answer:
RNA resembles a long chain with the links in the chain made up of individual nucleotide. RNA carries out the instructions encoded in DNA, most biological activities are carried out by proteins. The accurate synthesis of proteins thus is critical to the proper functioning of cells and organisms. The linear order of amino acids in each protein determines its three-dimensional structure and activity.For this reason, assembly of amino acids in their correct order, as encoded in DNA, is the key to production of functional proteins. Three kinds of RNA molecules perform different but cooperative functions in protein synthesis. Synthesis of all protein chains in prokaryotic and eukaryotic cells begins with the amino acid methionine. In most mRNAs, the start (initiator) codon specifying this amino-terminal methionine is AUG.In a few bacterial mRNAs, GUG is used as the initiator codon, and CUG occasionally is used as an initiator codon for methionine in eukaryotes. The three codons UAA, UGA, and UAG do not specify amino acids but constitute stop (terminator) signals that mark the carboxyl terminus of protein chains in almost all cells.The sequence of codons that runs from a specific start site to a terminating codon is called a reading frame. This precise linear array of ribonucleotides in groups of three in mRNA specifies the precise linear sequence of amino acids in a protein and also signals where synthesis of the protein chain starts and stops.

Explanation:
Tax cuts allow people to have more savings to invest or buy new things.
A) There are several factors that contribute to fast growth of economy. Tax cuts doesn't gurantee fast growth of economy
B) Tax cuts allow people to have more savings to invest or buy new things. So , tax cuts gives a relief to slowing economy. The slowdown becomes less rapid
C) impact of tax cuts can't be seen right away. It takes some time. Also, other measures like investments must be in place for economy to recoves. tax cuts eases slowdown first until people start investing for economy to recover.
D) Tax cuts do not slow down an economy.
Answer:
The Square Deal was Theodore Roosevelt's domestic program, which reflected his three major goals: conservation of natural resources, control of corporations, and consumer protection. These three demands are often referred to as the "three Cs" of Roosevelt's Square Deal.

Answer:
The Hacienda owners (Hacendados) in order to maintain constant exploit over their workers by maintaining a strict hierarchy in which the workers were practically feudal serfs. The way that they oppressed villagers and indigenous peoples was by forcing them off their land and leaving them with no other option but to work for them, whereafter they were exposed to harsh and underpaid hard labor.
Help I helped, either way, have a great day.
~ Those least likely to engage in physical activity were ages 65 and older (nearly 16 percent of exercisers). Not all was bleak, the CDC said. About 52 percent of surveyed adults said they met only the aerobic activity guidelines while 29 percent met only the muscle-strengthening components.
