Answer:
The answer is the purpose of the purchase.
Explanation:
A marketing company is a business record and leading standard proposal published by a customer to a merchant, showing varieties, sizes, and allowed charges for commodities or stints. It is employed to constrain the acquiring of commodities and militarizes from obvious suppliers. In extension, the consumer should forever acutely and explicitly state their requests to the agent so there is no trouble when the buying order is initiated.
Answer:
D

The atmosphere is not an eycosystem
Answer:
The main difference between sieve tubes and companion cells is that sieve tubes are the long, narrow, pointed tubes present in the phloem of angiosperms whereas companion cells are attached to the sieve tubes, regulating the activity of sieve tubes.
Answer:
The correct answer is: C. third nucleotide position.
Explanation:
- Genes located on the chromosomes encodes for proteins.
- A Gene is made up of a Deoxyribonucleotide (DNA) sequence which is transcribed into the messenger Ribonucleotide (mRNA) sequence by the help of RNA polymerase.
- This mRNA sequence is further translated into the amino acid sequence, that folds to form the functional protein, by the help of the Ribosome.
- The Ribosome reads the mRNA sequence in the form of triplets (three nucleotide together) and each such triplet nucleotide codes for an amino acid.
- Each such triplet nucleotide is known as a Codon.
- The Genetic Code is a table which represents the amino acid encoded by each codon.
- However, the Genetic Code is degenerate in nature. This means that one amino acid can be coded by more than one codon.
- This is because, among the the three nucleotide positions in a codon only the first two determine the specificity of the amino acid while the third nucleotide, also called the wobble nucleotide, is not specific. Presence of any nucleotide in the third position of the codon will not alter the amino acid encoded by the codon.
- In the given question, organisms producing homologous protein have similar amino acid sequence but they vary in the corresponding nucleotide sequence of the gene which codes for the homologous protein.
- This is because at the nucleotide level the variation lies in the wobble nucleotide position that occupies the third position in the codon.
<span>The grasslands typically lie in the middle of large lanmasses, or the interior of continents, where rivers are most likely to flow far away from seawater sources. Here the ever
present value of water can be seen, as it supplies the source of life to all the plants and animals in the ecosystem in a lush and relatively cushy environment when compared to
the biomes like the desert or savannah.</span>
