Plants are regenerate energy sun heat carbon dioxide nature of photosynthesis
Synthesis of compounds with the aid of radiant energy
Answer:
The reason for this is that both moss and fern species are relatively primitive plants that are only Imperfectly adapted to a terrestrial environment. ferns have both roots and vascular tissue and therefore, can grow larger than moss species, but like the mosses, ferns require water for reproduction.
The human gene for insulin production is identified and removed using enzymes called restriction enzymes. The same restriction enzymes are used to cut open a plasmid (a small, circular section of DNA).
The correct answer is this one: "C) Nnew = Nold + 2." A student is studying a process in which a diploid cell becomes haploid. The CORRECT mathematical model for the process if Nnew is the number of chromosomes in the haploid cell and Nold is the number of chromosomes in the diploid cell is this: <span>new = Nold + 2
</span>
Here are the choices.
<span>A)
Nnew = 2·Nold
B)
Nnew =
Nold
2
C)
Nnew = Nold + 2
D)
Nnew = Nold × 2</span>
Answer:
B) protein synthesis
Explanation:
An RNA codes for protein synthesis. A triplet of nucleotides/bases in RNA helps in adding an amino acid into the protein strand. This triplet of nucleotides is knwon as codon and helps in adding amino acid which is specific to it. For example, AUG triplet codes for methionine while UGG codes for tryptophan. The amino acids get added in protein strand unless a stop codon is reached. Triplets UAA, UAG & UGA are stop codons. Here it may be noted that initially a polypeptide chain is synthesized by RNA but the ultimate goal of making that polypeptide chain is protein synthesis.
