Answer:
Human blood contains a buffer of carbonic acid (H2CO3) and bicarbonate anion (HCO3-) in order to maintain blood pH between 7.35 and 7.45, as a value higher than 7.8 or lower than 6.8 can lead to death. In this buffer, hydronium and bicarbonate anion are in equilibrium with carbonic acid.

A dad has the genotype of AO and mom has the genotype of OO for blood
types. What percentage of offspring will have Type A blood? What are the
genotypes of all four potential offspring?"
Your answer
Answer:
0% will have type A blood. the 4 potential offspring genotypes are: AO, OO, AO, OO.
Explanation:
using a table, if you cross them, there is no way you'll get pure A blood. you can get AO blood, but never AA since that isnt on the table. then just use another table which ill find the name of later.

Explanation:
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..

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.

Epinephrine is a hormone that regulates cellular energy metabolism to break down glycogen into glucose. The signal transduction pathway involves the production of cAMP. If caffeine blocks the activity of cAMP, what would happen to the signal transduction pathway?
The signaling pathway will amplify and produce more glucose.
The signaling pathway will conform to bind to the receptor cells.
The downstream components will be altered and ultimately affect production of glucose.
The downstream components will function normally.
Answer: The downstream components will be altered and ultimately affect production of glucose.
Explanation: Epinephrine is a hormone that belongs to a class of biomolecules called catecholamines. When it reaches the target cell it binds to a receptor that is connected to an enzyme called adenylate cyclase that converts ATP into cAMP(cyclic adenosine monophosphate). cAMP plays an important role in the phosphorylation of proteins which alters their activity. In this case the activity of the enzyme that hydrolyses glycogen to glucose. When caffeine blocks the activity of cAMP it ultimately inhibits the action of the downstream components.
If caffeine blocks the activity of cAMP, then in the signal transduction pathway the downstream components will be altered and ultimately affect the production of glucose. Thus, the correct option is C.
What is Epinephrine?
Epinephrine is also known as adrenaline. It is a hormone which belongs to a class of biomolecules called catecholamines. When this hormone reaches the target cell it binds to a receptor present on the cell that is connected to an enzyme called the adenylate cyclase which converts ATP into cAMP (cyclic adenosine monophosphate).
cAMP plays an important role in the phosphorylation of proteins in the cell which alters their activity. In this case, the activity of the enzyme that hydrolyses glycogen to glucose.

Explanation:
As Mia mixed two substances in a test tube, she noticed that the test tube became warm. She also noticed gas coming from the test tube. Based on Mia's observations, what was most likely occuring inside the test tube?
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.
