Answer:
- bioremediation does not work well in areas where soils have a high day content, making them relatively impermeable
Explanation:
Answer:
False
Explanation:
Transfer RNA (tRNA) is a molecule synthesized from the process of transcribing DNA into segments located in specific regions of chromosomes. It is involved with protein synthesis in the mechanism of gene translation. This molecule is responsible for driving amino acids to form the polypeptide chains that make up proteins. While it is true that a cell has extensive regulatory systems to prevent the attachment of an incorrect amino acid to a tRNA, it is not true that the attachment of an incorrect amino acid is impossible, although rare, can happen.
So,
An atom is composed of a positively-charged nucleus and negatively-charged electrons. The protons and neutrons are packed very closely in the center, called the nucleus. The electrons are usually much further away from the center.
If we imagine a basic reaction, there are two atoms coming together. Since the protons and neutrons buried deep inside the atom, they cannot "react" with other atoms. Rather, the electrons, who are the most exposed, are the ones that change in a reaction.
