Answer:
The importance of the AUG and UGA bases lies in the fact that the first one is a start codon and the second one is a stop codon, respectively (option a).
Explanation:
Codons or triplets are sequences of three nitrogenous bases, in the mRNA, that determine the synthesis of a specific amino acid.
- <em>AUG </em><em>is called the </em><em>initiation or start codon</em><em>, and is usually at the beginning of a peptide synthesis, in addition to encoding the amino acid methionine.
</em>
- <em>UGA</em><em> is a</em><em> termination or stop codon</em><em> found at the end of a petid chain when it is complete. UAA and UAG codons are also STOP or termination codons and, together with UGA, do not code for amino acids.</em>
The biological importance of start and stop codons is to initiate the synthesis of a protein and to stop the addition of amino acids when their size is adequate.
Given:
base edge - 8 ft
altitude or height - 75 ft
Surface area = [(3√3)/2] a² + 3a[√h² + (3a²/4)]
S.A = 2.6*8² + 3(8) * √75² + [(3*8²)/4]
S.A = 166.4 + 24 * √5625 + 48
S.A = 166.4 + 24 * √5674
S.A = 166.4 + 24 * 75.33
S.A = 166.4 + 1807.92
S.A = 1974.32 ft²
convert square feet to square yard.
1 sq ft = 0.1111 sq yd
1974.32 ft² * 0.1111 sq.yd/sq.ft = 219.35 sq yd.
22 per sq. yard
219.35 sq. yard * $22/sq.yd = $4,825.70
Total cost is $4,825.70
Answer:
The reason that there is no fruit even the plant produced healthy flowers maybe because
1. absences of pollinators due to declining poliinator population
2.weather conditions are preventing pollination
3. prevalence of flooding
Explanation:
1.Fruits are direct result of pollination. Due to the decrease in the number of pollinators especially orchid bees, some fruit bearing plants produce flowers but no fruit.
Bees decline their population because of parasites, diseases, exposure to chemicals and other environmental factors.
2.Unfavorable factors may prevent the agents of pollination to do their jobs. Bees and other insects may be hindered by wet or cold weather or some use of chemicals.
3.Brazil nut grow in lowland rainforest where there is no flooding.
