Answer:
Yes, there is no convincing scientific evidence that thimerosal causes harm by the low doses of thimerosal in vaccines, except for minor reactions like redness and swelling at the injection site
Explanation:
Thimerosal has been used safely as a vaccine additive, added to some vaccines to prevent germs like bacteria and fungi from growing in them dated since early 1930s. Though, Thimerosal contains mercury but the type of mercury doesn’t stays in the body, and is unlikely to make human fall sick.
Most people doesn't have any allergic reaction to it except for redness and swelling at the injection site as early mentioned and this is considered irrelevant when compared to effect of vaccine when contaminated by germ which could cause serious illness or death.
Answer:
<u>C) They may provide selective advantages.
</u>
<u>D) Slight differences in the genetic code may have significant results.</u>
Explanation:
The genetic code is universal, and present in most living beings . Generally, in most living organisms, the same codons are assigned to the same amino acids.
DNA sequences make up genes that may have multiple variants, called alleles. DNA deoxyribonucleic acid, is transcribed into mRNA and then translated into amino acids that form proteins.
Natural selection mainly acts on phenotypes, which are dependent on proteins and the organisms's environment. Phenotypes conferring advantageous traits are favored by the selection process- these help groups of organisms evolve over time.
Answer:
Are there any choices to choose from?
Explanation:
Answer:
If it is still maintained in the human population, hemoglobin Lepore must be selected for in evolution.
