C. a toy train is the item that has characteristics similar to a scientific model.
Activated charcoal adsorbs many noxious substances—medical drugs, phytotoxins and poisonous chemicals—onto its surface, preventing their absorption from the gastrointestinal tract.
<h3>What is activated charcoal ?</h3>
Activated carbon, sometimes known as activated charcoal, is a type of carbon that is frequently used for a variety of purposes, including the filtration of impurities from water and air. It is treated to have tiny, low-volume holes, which expand the surface area open to chemical reactions or adsorption.
- For some poisonings, activated charcoal is utilised as an emergency therapy. It aids in preventing the body from absorbing the toxin from the stomach. To treat severe poisoning, activated charcoal may occasionally be given in multiple doses.

im not quite sure what the answer is but if its true and false then the answer is true
Answer:
DNA ligase
Explanation:
DNA replication is an enzyme mediated, 3-step process during which the DNA molecule produces a copy of itself. The 3 steps involved are as follows;
- initiation
- elongation
- termination
<em>Initiation </em>involves the unwinding of the double helix structure of the DNA using DNA helicase enzyme
<em>Elongation</em> involves binding of RNA primer to the DNA strands and addition of bases to the primer<em> </em>to elongate the new chains. Bases are added to the leading strand continuously while the lagging strand is replicated in short segments (okazaki segments).
<em>Termination</em> involves the unbinding of RNA primer and substitution of its bases by DNA bases. The Okazaki fragments are then joined together using the DNA ligase enzyme.
<em>The short, numerous segments of DNA observed in the mixture is the Okazaki fragments of the lagging strand. This is due to the absence of the enzyme involved in the joining of these fragments.</em>
Hence, the answer is DNA ligase.
