If those are the optional answers, it's most likely sodium.
Well,
By the word "deletion" we can deduce that information is lost. Therefore, when a chromosome undergoes a deletion mutation, information is lost. This can have disastrous effects if it is a human chromosome.
Answer: B
Explanation:
Ammonia is so toxic that it can be transported and excreted only in large volumes of very dilute solution. As a result most terrestrial animals simply don't have access to sufficient water to routine excrete ammonia.
The main advantage of urea is its very low toxicity. Animals can transport urea in the circulatory system and store it safely in high concentrations. Also much less water is loss when a given quantity of nitrogen is excreted in a concentrated solution of urea than would be in a dilute solution of ammonia.
Answer:
<h2>Genotype, sequence, mRNA, cytoplasm, proteins, phenotype</h2>
Explanation:
The allele combination at a gene locus is known as an organism's genotype, which after expression define the phenotype of that organism.
Th sequence of nucleotide in the DNA then transcribed to produce mRNA by RNA polymerase. Then mRNA exported into the cytoplasm and works as template for the synthesis of protein. This protein defines the phenotype of that organism.
