True. Glutathione is used as a reducing agent (antioxidant) in cells to keep redox enzymes in a reduced state and remove toxic peroxides.
With regard to the reducing properties of glutathione, it plays to exhibit the role of an antioxidant that helps in scavenging electrophilic as well as oxidant species either in a direct way or by catalysis of enzymes. It can directly quench hydroxyl free radicals which are highly reactive, oxygen-centered free radicals, and DNA radical centers and on other biomolecules also.
Glutathione act as a ubiquitous tripeptide that contains thiol that plays a protective role of cells under a condition of oxidative stress. It also modulates the response of a cell to some kind of major redox changes through antioxidant gene expression regulation.
Thus the statement is true since glutathione act as a reducing agent to keep cells in a reduced state and also removes toxic peroxides.

Imagine that, of three species, it is known that species 1 and 3 were separated 10 million years ago, based on geologic measurements. Genetic analysis at a neutral locus indicates that these species differ by 100 substitutions. If there are 10 substitutions separating species 1 and 2, approximately how long ago did these species diverge?.
(C) 1 million years ago is the approximate time that the species diverge. This is because Genetic analysis at a neutral locus indicates that these species differ by 100 substitutions. If there are 10 substitutions separating species 1 and 2.
Divergence in evolutionary biology refers to an evolutionary process in which a population of an inbreeding species splits into two or more descendant species that have progressively diverged in their morphologies and structural characteristics.
The difference between species 1 and 3 is 100 substitutions, and humans split off 10 million years ago. As a result, there will be 10 substitutions in a million years. As a result, 1 million years ago, species 1 and 2, which are divided by 10 substitution, diverged.

why you think rust forms on metal. Then read the lesson to learn the role of chemical reactions in living things.
Answer: I think rust forms on metal because it is exposed to oxygen and which it begins to corrode.
Explanation:
In the origin of cells, why was it important that complex molecules become enclosed in a lipid membrane?
In the origin of cells, it was important that complex molecules become enclosed in a lipid membrane so that the complex molecules could be isolated from the environment and also to stop them from diffusing.
A cell membrane is a semi-permeable membrane made of lipids and other compounds. The lipid membrane separates the interior of a cell from the exterior of the cell.
In the origin of cells, the presence of a cell membrane was important in order to form life. Without the cell membrane, all the complex molecules required for existence would not have been separated from the outside environment. Also, many of the molecules would have diffuses if a lipid membrane was not present around them.
A cell membrane made up of lipids was the most suitable choice because lipids are amphiphilic in nature.

The difference of a number and 16 is the equal to 45 what is the value of that number? Plss show work and explain
Answer:
So your two numbers are 10 and 25.
Explanation:
Call one of these numbers x and one of them y.
We know x+y = 35
We know x-y = 15
Add y to both sides of the second equation to get x=15 + y
Then plug this into the first equation as x --> (15 + y) + y = 35
This simplifies to 15+2y=35 by adding the y's.
We can subtract 15 from both sides to get 2y=35-15, which is 2y=20. Then divide both sides by 2 to get y=10. This is one of the numbers!
Then plug this back in to either equation above. I'll use the first equation that is x + y = 35. y=10, so x+10=35. subtract 10 from both sides to get x=35-10, so x=25.

A client is scheduled for elective cardioversion to treat chronic high-rate atrial fibrillation. which finding indicates that further preparation is needed for the procedure?
The finding that the client is wearing a nasal cannula delivering oxygen at 2 L per min needs further preparation for the procedure of electrical cardioversion.
Electrical cardioversion is used to treat various abnormal heart rhythms. Irregular heart rhythms can cause problems like apoplexy, stroke, or even sudden cardiac death. Artrial fibrillation (A-F) is ususally treated with this technique. A-F is a condition in which the atria of the heart shiver instead of producing a rhythm. It thus produces a rapid heartbeat and can cause a risk for apoplexy.
To start with the procedure, electrodes are stuck to the body. Electrical signals are then sent to your heart through these electrodes. Any oxygen from your body is removed before initiating the procedure because oxygen aids combustion and can result in electrical sparks inside the body and can cause flickers.
Patients are usually put on oxygen before the procedure to provide them sufficient amount of oxygen and make them stable for the procedure. Intentionally, Digoxin is kept withheld for 48 hours and food and fluids for 12 hours before the procedure.

Answer:
Glomerular filtration is driven by bulk flow due to capillary hydrostatic pressure
Explanation:
Production of urine starts with glomerular filtration. It refers to the procedure that kidneys utilize to filter extra fluid and trash from the blood further into collecting tubules, allowing the body to remove them. Blood enters the glomerulus, a collection of small blood veins, as it reaches each nephron. Atoms and smaller molecules, debris, and excess fluid water—can pass through the glomerulus' sidewalls and enter the tubule. Protein as well as blood cells, which are bigger molecules, remain in the small blood vessels. While it may come as a surprise to everyone, it is totally common for the blood pressure to change during the course of the day; fortunately, this has no impact on the filtration rate of glomerular.
