Answer:
B. Solution
Explanation:
According to the question statement, Susan wrote in her notebook that it was a blue liquid. Therefore, from a chemistry point of view, it was a solution and not a heterogeneous mixture. Then, the solvent was evaporated after leaving the solution for 72 hours at the windowsill. The solute (blue color most likely) however was not able to evaporate with solvent and left behind.
Example: if you leave the KMnO4+water solution for a few days, water will evaporate thus leaving behind purple crystals of KMnO4.
The order in which the amino-acids are placed within the polypeptide determines the tertiary structure and therefore the function of the given protein. Amino acids have different functional groups like methyl(CH3), phenyl(C6H5). Those functional groups can interact with molecules like glucose determining reactions, the proteins that catalyze reactions are called enzymes. Other functional groups of amino acids can be the sulfate groups. For example, insulin has 2 polypeptide chains(Chain A has 21 amino acids, and chain B, 30). Between the two polypeptide chains, 2 disulfide bonds form altering its shape.
The following statement is false: MOST US STATES PROHIBIT THE IMPORTATION OF ANIMAL SPECIES LIKELY TO BECOME INVASIVE IF THEY ESCAPE INTO THE WILD.
Presently, most US states do not have any law, which prohibit people from bringing into the US animal species that are likely to become invasive.
Invasive plant and animals are a great source of problems in America. These species usually destroy habitats and native species, this usually throw the ecological communities out of balance. The government spend as much as $120 billions every year to control these invasive species.
Answer:
An insertion changes the number of DNA bases in a gene by adding a piece of DNA. As a result, the protein made by the gene may not function properly. Deletion. ... This type of mutation occurs when the addition or loss of DNA bases changes a gene's reading frame.
