It gives whoever comes into contact with it a nasty and itchy rash that lasts even after you bather or wash it off.
OR
<span>It starts an immune system response that causes a rash</span>
Answer: An antigen
Explanation:
A molecule that evokes immune response in the body of an organism is known as antigen. These substance can be protein, carbohydrates, lipids when asked for chemical nature.
Physically these substance can be dust particles, smoke, pollen grains, some food particles. Antigen can be defined as the substance that tends to produce immune response by the immune system of the body.
Hence, the correct answer is option D
before wasting energy on stopping a response mechanism halfway through, you want to stop the process. feedback restraint at the outset.
Everything in cell metabolism happens extremely sequentially. A process will produce waste if you let it run on its own. First, the regulatory enzyme reduces waste by stopping the entire pathway.
<h3>Which enzymes fall under the regulatory category?</h3>
Kinases are regulatory enzymes that make it easier to transfer phosphate groups to particular substrates. Protein kinases are one of the many types of kinases that play a role in controlling and further modifying cellular activity.
<h3>Which three regulatory enzymes are there?</h3>
Citrate synthase, isocitrate dehydrogenase, and beta-ketoglutarate dehydrogenase are the three enzymes that control the TCA cycle. The irreversible stages of the TCA cycle, which are the primary point of regulation, are catalyzed by these enzymes, which are allosterically regulated.

Answer:
Molecules stop moving at freezing point. Helium has the lowest boiling point. The molecules move very quickly at boiling point.
Explanation:
Heating up- molecules move faster. Cooling down- molecules move slower
