Answer:

I'm assuming you meant pool instead of poolon, i'll take it as a grammatical error. Anyhow, the water in a pool on sunny days tend to have less chlorination then on regular days. This is because chlorine forms hypochlorite ions in the water, and these are broken down by the ultraviolet light from the sun. Rainy or shiny, the weather is always affecting the chemistry in your pool.

Now, if you want to get more complicated into it, you can add a stabilizer into the pool. The common one safely used in pools is cyanuric acid. This almost completley prevents all de-chloronification.

I hope this information was of any use to you.

Haloperidol is an antipsychotic drug (or neuroleptic drug) used to treat all kink of psychosis, like this young woman in the reported case.

Extrapyramidal symptoms may occur during treatment, specifically in the first weeks (eg, tremor, stiffness, hypersalivation, bradykinesia, akathisia, acute dystonia).Acute dystonia may also occur during the first few days of treatment with Haloperidol, it may include torticollis, facial grimace, trismus, lingual protrusion, and abnormal eye movements, including the oculogyric crisis...

The risk of occurrence of these reactions is greater in male and younger patients. In case of acute dystonia, it may be necessary to stop taking the drug.

digestive enzymes released in your mouth break down carbohydrates there but stop working in your stomach. which is the most like

horrorfan [7]

The most likely explanation to the statement that digestive enzymes released in your mouth break down carbohydrates there but stop working in your stomach is C. The pH of your mouth and stomach are very different. The shape of the enzyme is affected by pH.

The pH of the mouth is near neutral whereas the pH of the stomach is acidic due to the hydrochloric acid present in the stomach.

All enzymes, including the digestive enzymes, require a certain pH at which they are better able to function. If the pH is altered, then the shape of the enzyme changes, which affects the shape of the active site of the enzyme. As a result, the substrate is no longer able to fit in the active site.

Hence, those digestive enzymes that function in the mouth will not function in the stomach due to the altered pH.

Although a part of your question is missing, you might be referring to this question:

Digestive enzymes released in your mouth break down carbohydrates there but stop working in your stomach. which is the most likely explanation?

A. Enzymes have only one active site. Once a substrate binds, that enzyme is no longer usable.

B. Enzymes are changed in a reaction. Enzymes made in the mouth are used up by the time they get to the stomach.

C. The pH of your mouth and stomach are very different. The shape of the enzyme is affected by pH.

D. There are no substrate molecules left when the enzyme reaches the stomach, so the enzyme stops working.

STatiana [176]

Answer:

Option (3).

Explanation:

Teratogens may be defined as the chemicals that can cause birth defects in the fetus. Substances like alcohol, lead and nicotine acts as the main agents of tertaogens.

Shamona is drinking water that contains high level of lead. The element lead is harmful for the fetus. Even the small concentration of lead is enough to cause birth defects. The lead exposure can cause the abnormal development of brain and damages the brain of fetus. The fetus has low birth weight also.

Thus, the correct answer is option (3).
