Answer:
The correct answer would be - a new substance is forming.
Explanation:
A reaction can lead to two types of changes in the substances reacting, it could be chemical change or physical change or both. Physical changes are deal with the change in the state of the matter and other physical changes whereas chemical change leads to the formation of a new substance by the altering composition of the substances.
Chemical changes involve a change in temperature, formin and releasing gas, or changing the color of reactants. In the given case, Mia mix two substances which leads to an increase in temperature and release gas by this reaction which tells there is a chemical reaction forming a new substance.

If your stomach produces too much acid you can take a substance that is a _________ to Neutralize it
Answer/Explanation:
When you stomach builds up too much gastric acid you can take an antacid to Neutralize it. Antacids are a base used to Increase the pH level of the stomach fluids. Increasing the pH levels to about 7 will make it neutral. An example of an antacid would be Tums.
➜ We can take antacid to neutralize the effect of excess acid (hydrochloric acid). Antacid are generally medicine that is used to neutralize the excess amount of acid. It has a basic nature and makes the Ph of stomach about to 7 to feel relief by neutralization reaction.
E.g ⇢ Milk of magnesia, Amphojel..
A patient is given antihistamines due to an allergic reaction where vascular permeability is increased, causing watery eyes. Which of the following describes how antihistamines affect a signal transduction pathway?
Antihistamines block histamine from binding to the appropriate receptor.
Antihistamines reduce histamine in the blood by binding to and destroying it.
Antihistamines reduce the amount of histamine in the bloodstream by binding to and inactivating histamine.
Antihistamines produce a second messenger that interrupts and reverses the direction of the signaling pathway.
Answer:
Antihistamines affect a signal transduction pathway by blocking histamine from binding to the appropriate receptor (First option).
Explanation:
Antihistamines are a group of drugs used in allergic reactions mediated by the immune system. Specifically, antihistamines are competitive inhibitors of histamine binding to its specific receptor, the histamine H1 receptor.
Histamine is an inflammatory mediator, being one of the substances of the humoral immune response. It is secreted by mast cells and is responsible for the production of allergic effects, such as nasal congestion, sneezing, skin rash, and red, watery eyes. Antihistamines block histamine from binding to the appropriate receptor, preventing these effects.
The other options are not correct, because they do not correspond to the effects of antihistamines, that is, it does not bind to histamine, destroy it or render it inactive..
