Answer: A group that closet matches characteristics
Explanation:
A representative sample is a group that closely matches the characteristics of its population as a whole. In other words, the sample is a fairly accurate reflection of the population from which the sample is drawn.
the gases that kept different planta is A
Answer:
- compare and contrast
- DNA replication works
- process of transcription
Explanation:
COMPARE AND CONTRAST:
DNA is a double-stranded molecule while RNA is a single-stranded molecule. DNA is stable under alkaline conditions while RNA is not stable. ...DNA and RNA base pairing is slightly different since DNA uses the bases adenine, thymine, cytosine, and guanine; RNA uses adenine, uracil, cytosine, and guanine
HOW IT WORKS:
How is DNA replicated? Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.
PROCESS OF TRANSCRIPTION:
Transcription is the process in which a gene's DNA sequence is copied (transcribed) to make an RNA molecule. RNA polymerase is the maintranscription enzyme. Transcriptionbegins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins).

Answer: The frequency of the b allele is calculated as follows: since there are 2 alleles in each organism, total number of genes is 200. The number of white alleles is 10*2+30 (since there are 2 copies of the alleles in white organisms and 1 copy of the b allele in the white wings with blue blotches). So the total number of white alleles is 20+30=50 white alleles. The frequency of the white allele is then 0.25. So the frequency of the blue allele is 1-0.25=0.75. Since heterozygous term is 2*p*q, the frequency of the Bb genotype is 2*0.25*0.75=0.375. Hope that helped!
