Answer:

The answer is C.

Explanation:

This is because for A, this statement says nothing about corundum being yellow which means that this doesn’t apply and is incorrect. For B is pretty much the same as A, this statement about corundum doesn’t say anything about it being able to flavor or being flavorful. Lastly for D, the fact that corundum is hard means it would be impractical and probably impossible to use it as pencil lead because, all lead it doing with a pencil is being crushes and ground into the paper as you write.

Hope this helps.

Express this sense sequence as a polypeptide. Use the three letter abbreviation and separate the amino acids with a dash - e.g.

jek_recluse [69]

Answer:

- Protein sequence: Met-Pro-Gly-Lys-Ile-Arg-Arg-Pro-Pro-Gly-Thr-Pro-Leu-Phe-Gly-Lys-*

- DNA 5' UTR: ATTTTAGCC

- RNA 3' UTR: UAAAAAUAAAAU

Explanation:

Transcription is the process in which a DNA sequence (e.g., a gene) is used as template (transcribed) in order to synthesize an RNA molecule, usually a messenger RNA molecule, which is then used as template to produce a polypeptide sequence (protein) in the ribosomes. In RNA, Thymine (T) bases are always replaced by Uracil (U) bases. An mRNA strand is formed in the 5′ to 3′ direction. Each triplet of nucleotides is referred to as a codon and the resulting mRNA strand is translated starting from codon AUG (Methionine), while there are three different stop codons or 'or termination codons' in the genetic code that terminate translation: UAG, UAA, and UGA.

In the kidneys, the countercurrent mechanism involves the interaction between the flow of filtrate through the loop of Henle of

Irina18 [472]

<em>Answer:</em>

<em>The answer for this statement is "True".</em>

<em>Explanation:</em>

<em>In the kidneys, the countercurrent mechanism involves the interaction between the flow of filtrate through the loop of Henle of the juxtamedullary nephrons (the countercurrent multiplier) and the flow of blood through the limbs of adjacent blood vessels (the countercurrent exchanger). This relationship establishes and maintains an osmotic gradient extending from the cortex through the depths of the medulla that allows the kidneys to vary urine concentration dramatically which is true.</em>

Population genetics is the study of _______.

Mrrafil [7]

According to the research, the correct option is A, population genetics is the study of how allele frequencies in a population change over time.

<h3>What is population genetics?</h3>

It studies the origin, amount and distribution of genetic variability present in populations.

It explains the variation between individuals, as well as the dynamics of alleles and genotypes within and between populations.

Therefore, we can conclude that according to the research, the correct option is A, population genetics is the study of how allele frequencies in a population change over time.
