Why a thin film of oil spread over water while water do not spread over oil?
This will occur because most oils (especially cooking oils) are less dense than water. So when poured into water they will stay separate and on top. When water is poured into oil it will sink to the bottom instead of float on top.
How is fat mobilized from adipocytes?
When the body needs to mobilize fat for energy, hormone-sensitive lipase is activated in adipocytes to break down triglycerides into fatty acids and glycerol. These fatty acids are released into the bloodstream to be taken up by other tissues, such as muscle cells, where they can be used for energy production.
What is the polyatomic name for CH3COO- and why is that formula more accurate?
It stands for acetate.
[CH3CO0]- lets you know what the molecule looks like.
It will be C with 3H attached to it one one side, than another C with 2O attached to it on the other side (one O will be double bond).
3H-C-C-2O (with one O double bond)
C2H2O2 just tells you what elements and how many of each element you get in the formula.
Liposomes are characteristic of what type of lipid?
Liposomes are characteristic of phospholipids, which are a type of lipid that consists of a hydrophilic head and two hydrophobic tails. This structure allows phospholipids to form lipid bilayers that can encapsulate drugs or other molecules within the liposome structure.
What six hormones primarily affect growth?
The six hormones primarily affecting growth are growth hormone (GH), insulin-like growth factor 1 (IGF-1), thyroid hormones (T3 and T4), insulin, testosterone, and estrogen. These hormones play key roles in regulating growth and development during different stages of life.
The Substrate for amylase are starch (amylose and Amylopectin), glycogen, and various Oligosaccharides.
A covalent inhibitor is one that forms a stable covalent bond with an amino acid residue within the active site of an enzyme. This kind of interaction can irreversibly inhibit the enzyme's activity by blocking its active site or altering its structure. Examples include penicillin binding to serine in the active site of penicillinase.
Fish breathe in water with oxygen. What is the property of water?
The property of water that allows fish to breathe is its ability to dissolve oxygen. As water flows over the fish's gills, oxygen molecules from the water diffuse into their bloodstream, allowing them to extract oxygen for respiration.
How do monosaccharides differ?
Monosaccharides differ in the number of carbon atoms they contain, ranging from 3 to 7 carbons. They also differ in their chemical structure, such as the arrangement of hydroxyl groups and the presence of functional groups like aldehydes or ketones. Moreover, monosaccharides vary in their sweetness, solubility, and reactivity based on their specific structure.
What vitamin contributes to healthy skin and a good appetite?

Vitamin A and Vitamin C is also vital to take in if you want to keep your skin healthy :)
Vitamin B is also very good for your skin, you can find Vitamin B in bread, rice, pastas and whole grains.
Why is protein synthesis different in prokaryotes and eukaryotes?
In prokaryotes, DNA is stored in the cytoplasm.
also prokaryotes have no nucleus
In prokaryotes, transcription and translation happen at the same time.
How do you know when something is an enzyme?
enzymes can build structures inside the body, can help provide the body with energy or can break down structures or molecules in various places in our body, they also work as a digestive enzymes
hope that helps
The primary function of ribosomes is to coordinate in which biosynthesis?
Ribosomes primary function is to coordinate protein biosynthesis in the cell by translating messenger RNA (mRNA) into a specific sequence of amino acids to form a protein.
What is biological method of study?

What is an element of Dna that is not found in amino acids?
Thymine is an element of DNA that is not found in amino acids. Thymine is one of the four nucleotide bases in DNA, along with adenine, guanine, and cytosine, and it plays a crucial role in encoding genetic information. Amino acids, on the other hand, are the building blocks of proteins and are not part of the DNA molecule.
Microsomal oxidation is the type of biological oxidation catalyzed by special cytochrome P-450 (CYP) enzyme group (superfamily) which takes place predominantly in hepatic microsomes, which are fragments of liver cells endoplasmatic membranes.
What are two factors that affect an enzyme function?
Temperature, pH, solute concentration, and salt content just to name a few. Temperature and Ph affect the function of enzymes because our body has a temperature of around 37 degrees and the conditions in our stomach are acidic. So9f or the enzyme to work properly then the working condidtions have to be at least 37 degrees and they need to acidic otherwise the enzyme won't work properly.
Is the Cell membrane considered to be a part of the Cell's protoplasm?
Yes, the cell membrane is considered to be part of the protoplasm in a cell. Protoplasm includes all the living components of the cell, such as the cytoplasm and organelles. The cell membrane surrounds the cytoplasm and organelles, helping to define the boundary of the cell.
Would a direct injection of alcohol be fatal?
in college i read about a man who had throat surgery and was an alcoholic he had an idea to pump alcohol into his bowels using an enema pump his blood alcohol raised about 4.7 and he passed away with 20 minutes since the skin inside the rectum is so thin, you can kill yourself with one injection -doent matter the kind or the proff, because the blood has no way to filter it all blood in the human body goes directly to the heart to be cleaned and pumped back ....the waste goes into your kidneys and comes out as pee,so a direct hit of alcohol would kill you and it would burn and hurt like hell, like rubbing salt in an open wound, like snoring salt up you nose, it will kill you with in 30 minutes or less that not enough time to call 911 or even get to the hospital.dont be stupid put the syringe down and go find something constructive to do like cooking or painting or poetry or dance.
What is another name for platelet blood Cells?
Thrombocytes contain an occasionally active thrombin protein.
Can electricity pass through a glass bottle with a plastic cap?
Yes, electricity can pass through a glass bottle with a plastic cap if the bottle is filled with a conductive liquid (like water) that allows the flow of electric current. The glass and plastic materials act as insulators, but the conductive liquid inside the bottle enables the electricity to pass through.
What are the concepts of catabolism?
Catabolism is the breakdown of complex molecules into simpler ones to release energy. It involves processes like glycolysis, the citric acid cycle, and the electron transport chain. These reactions provide the energy needed for cellular functions.
Why Benedict's solution turns green in urine test?
Benedict's solution is used to test for reducing sugars like glucose in urine. When glucose is present, it reacts with Benedict's solution to form a colored precipitate. The color change from blue to green, yellow, orange, or red depends on the amount of reducing sugar present in the sample.
How much vitamin c does a child need?
The best practice is to discuss this with your child's health care practitioner but the reputable sites and the USDA suggest about 25mg - 45mg of Vitamin C is adequate for children. If your child's diet consists of a variety of fruits and vegetables then they may already be getting enough Vitamin C and do not require supplements.
Here is a link to the USDA - Food and Nutrition Board, National Academy of Sciences, National Research Council list of Vitamins and Supplement recommendations for children.
From personal experience it was difficult to find supplements that had such low levels of Vitamin C but we did find one finally, a product by Floradix called Kindervidal which has many different vitamins and minerals including 25mg Vitamin C. We just simply mix it in with our child`s water or juice every morning.
Another answer
You can find Vitamin C in Whole foods or similar health stores, I don't think 25mg is enough for a child. I would do more research on it. Adults need over 1000mg a day. It's not harmful, only will give you diarrhea if you take too much for your system. All you need to do is take less until it stops and you find the proper dose for yourself.
To calculate this, we need to know the energy expenditure rate of walking for that person. On average, walking burns around 100 calories per mile for a 160-pound person. For a 67.5 kg person (approximately 149 pounds), it would be a bit less. Assuming the walking speed is around 3 mph, the person would have to walk roughly 4-5 hours to burn the 430 kcal in the cheeseburger.
