10 In a solution of 10% sugar and 90% water, I have placed a cell that contains 30% sugar and 70 % water. Which of the following describes OSMOSIS in this situation? A. Water moves into the cell B. Water moves out of the cell C. Water moves in and out equally D. Water does not move in the above situation. 11 Which of the following terms would best describe the effects on that cell? A. Apoptosis B. Crenation C. Lysis D. No effect of the cell
Answer:
A. Water moves into the cell
C. Lysis
Explanation:
Water moves into the cell due to high concentration of solutes i. e. sugar. If a cell has low concentration of solute than outside environment so the water moves outside toward more solutes while when the concentration of cell has more solute than external environment so water moves inside the cell towards more solute through the process of osmosis. Due to more diffusion of water into the cell, the Lysis will occurs in which the cell will burst due to expansion of its area.

What is the definition of a protein-binding site?Choose one:A. the region of the cell where proteins are assembled based on information from the genetic codeB. a pocket on a protein where a small molecule can be covalently attached and thus modify the proteinC. the portion of a protein that attaches to the cell membrane and tethers the protein as a peripheral membrane proteinD. any region on a protein’s surface that interacts with another molecule through noncovalent bonding
Answer: I think this is C
Explanation:
Plasma protein binding refers to the degree to which medications attach to proteins within the blood. A drug's efficiency may be affected by the degree to which it binds. The less bound a drug is, the more efficiently it can traverse cell membranes or diffuse.
The protein-binding site is any region on a protein’s surface that interacts with another molecule through noncovalent bonding. The correct option is D.
Why is protein-binding site important?A binding site is any region of a protein's surface that can interact with another molecule via noncovalent bonds. A protein can have binding sites for many different molecules, both large and small.
Protein binding is most clinically important in antimicrobial therapy, where a high degree of protein binding acts as a drug "depot,".
It allow for a longer duration of time the drug concentration remains above the bacterial minimum inhibitory concentration, thereby increasing antimicrobial efficacy.
Ligand binding sites are involved in a variety of protein biological processes, including signal transduction and enzymatic activity.
Understanding the properties of binding sites is critical in drug development and protein engineering.
Thus, the correct option is D.

If a solution is undergoing a reaction where CO2 is being created a product, what color is the phenol red-containing solution shifting toward?
Answer:
YELLOW
Explanation:
Phenol red is a biological indicator used to monitor changes in pH. The phenol red indicator changes color ranging from yellow to pink with respect to changes in pH. In an acidic pH i.e. <7, the phenol red changes to a YELLOW color while in an alkaline pH i.e. >7, the phenol red changes to a PINK pH.
The presence of carbon dioxide (CO2) increases the hydrogen ion concentration (H+) of a solution (lowering its pH or making it acidic).
Therefore, in a reaction where CO2 is created as a product, it means the CO2 content of that solution increases. Hence, the phenol red solution will be shifting towards the YELLOW color in response to a decreasee in pH (acidic).
If a solution is undergoing a reaction where CO2 is being created a product, the phenol red-containing solution will be shifting toward the yellow color.
An indicator is an organic dye that changes its color as the pH of the solution changes. An indicator has a different color in acid, base and neutral media.
Phenol red has a yellow color in acidic medium and red color in a basic medium.
Since the production of CO2 lowers the pH of the system, the color of the solution shifts towards yellow.

PALS Which statement about hydrocortisone is NOT correct? Hydrocortisone cannot be used for adrenal insufficiency associated with septic shock. A common side effect is hyperglycemia. Hydrocortisone inhibits vascular leak due to proinflammatory mediators. Hydrocortisone is classified as a corticosteroid.
Answer:
Hydrocortisone inhibits vascular leak due to proinflammatory mediators.
Explanation:
Hydrocortisone is a corticosteroid anti-inflammatory medication capable of reducing the body's immune response, and thus reduce pain and itching. Hydrocortisone treatment is used in different health problems, including, among others, piles and itchy bottom, mouth ulcers, skin problems, adrenal insufficiency, etc. This drug is also utilized in persons that don't produce enough cortisol, a natural stress hormone. It has been shown that hydrocortisone may lead to enhancement of vascular leak, which suggests secondary effects on myocardial and endothelial cells.
Hydrocortisone inhibits vascular leak due to proinflammatory mediators.
Hydrocortisone is a corticosteroid anti-inflammatory medication that relieves pain and itching by decreasing the body's immunological reaction. It is used to treat piles and itchy bottoms, mouth ulcers, skin diseases, adrenal insufficiency, and other conditions. People who don't produce enough stress hormones may benefit from this medicine.

16.)Which of the following properties of water help to dissolve sugar?
A.) adhesion
B.) cohesion
C.) surface tension
D.)Universal Solvent
Answer:
D
Explanation:
The property of water that helps it to dissolve sugar is the universal solvent property.
Water has the inherent attribute to dissolve a wide variety of substances due to the arrangement of the atoms that make up water molecules. The molecules of water are made up of hydrogen and oxygen, with the latter being negatively charged while the former is positively charged.
The polar arrangement gives water the capacity to be able to dissociate ionic substances into their respective positive and negative ions and also allow water to dissolve more substances than any other solvent in the world.
The correct option is D.
Why do doctors have to check what blood type a person has before receiving a transfusion?
A. Different blood types have different antibodies that will be attacked by someone with antigens against that blood type.
B. Different blood types have different antigens that will be attacked by someone with antibodies against that blood type.
C. They need to have the same blood type because their DNA must be similar enough to blend or will cause side-effects and possibly be rejected.
D. Your blood type doesn't matter as long as you get the correct amount of blood in a transfusion.
Answer:
A and B
Explanation:
Doctors need to check the blood type of a person before administering blood transfusion because different blood types have different antibodies that will be attacked by someone with antigens against that blood type.
The blood that would be given to a person must match the blood of that person in terms of the type of antigens. If the blood antigens are different, the antigens present in the blood of the individual undergoing blood transfusion would consider the antigens present in the blood being received as an enemy and attack it. This will lead to agglutination of the blood in the system of the person, a process that often leads to death.
Hence, O-positive individuals must always receive O-positive blood while O-negative individuals must always receive O-negative blood.
The correct options are A and B.

For certain medical procedures, body parts (such as organs and tissues) may require transportation over great distances. Certain procedures must be followed in order for the body parts to remain usable for the patient. During a pancreatic transfer, specialists have to be mindful of trypsin (an enzyme located in the pancreas). If the trypsin is functioning normally during such transfers, early decay of the pancreas will occur. If the pancreas decays, the transplant will be unsuccessful. Examine the graph below. Which of the following procedures would be necessary for a team of clinical specialists to follow in order to ensure a successful transplant?
Answer:
Hello. You did not add the necessary graphics for this question to be answered. However, I can help you by showing that one of the procedures that a medical team can do to inhibit the action of trypsin in the deorization of the pancreas is the use of ulinastine.
Explanation:
During the process of isolating a pancreas to be transported, the use of ulinastine is shown to be efficient for inhibiting trypsin, which promotes deterioration of the pancreas. Unilastine is also an anti-inflammatory, which will bring even more benefits with its use.
Thus, with the use of a ulinastine solution, the pancreas has more time to reach the transplant site and promote successful surgery.
