What is the basis of the test for cellulose with Shultz stain?

Proteins get denatured when acid is added and this forms a white coagulum which is slightly yellow in colour because of nitro- derivatives of proteins given by aromatic amino acids.

What type of gas can be used to knock someone unconscious in under two hour that are vapors at room temperatures and also ones that won't kill the person harm them like mustard gas?

Nitrous oxide (laughing gas) or chloroform are two gases that can be used to knock someone unconscious in a gentle manner within two hours. It is important to note that using any gas for this purpose should be done under medical supervision to ensure safety and proper dosage control.

Which sugar are present and not present in the fruit juice?

Fruit juice naturally contains fructose and glucose sugars from the fruit itself. Sucrose, a disaccharide made up of fructose and glucose, may also be present depending on the fruit processed. Lactose, a sugar found in dairy products, would not typically be present in fruit juice unless it has been added during processing.

Can i use saline citrate buffer for DNA extraction from tissue of bivalve?

Yes, saline citrate buffer can be used for DNA extraction from bivalve tissue. It helps in breaking down cell membranes and proteins, releasing the DNA for further extraction and purification steps. Ensure to follow a tested protocol for optimal results.

What sugars does starch break down into?

sugar
Starch is a carbohydrate.Starch is broken down into moltose or glucose.
Starch is broken down into glucose by enzymes during digestion. Starch is a polysaccharide that must be broken down into a simple sugar called a monosaccharide. Glucose is a monosaccharide.

Is the Cytoskeleton the same as Cytoplasm?

No, the cytoplasm is the cell contents between the membrane and the nucleus; organelles and liquid. The cytoskeleton is a frame work and also an internal highway of the cell that is made of microtubules.

Which amino acid has a ring?

Histidine is an amino acid that contains an imidazole ring in its side chain. The imidazole ring gives histidine unique chemical properties, making it important in enzyme catalysis and protein structure.

Which amino acids have ring of side chain covalently linked to peptide backbone?

There are three and they are called aromatic amino acids: tryptophan phenylalanine tyrosine.

What are the pros and cons of artificial plant hormones?

Advantages: When soil has no more natural supply of nitrogen, the fertilizers give nitrogen back to the soil.

Disadvantages: Any nitrogen that isn't absorbed leaks into water supplies and creates large growths of algae, which can be harmful to other aquatic species.

How does DNA replicate ensure continuity of form and function from one cell generation to the next?

The fidelity of replication is backed by corrective mechanisms to ensure that said replication is a perfect as possible and the same protein structure is being coded for in the daughter cells. Naturally, no process is perfect and mutations will happen, but they are, generally, neutral.

38 ATP is formed in one glucose. How?

During cellular respiration, glucose is broken down through a series of metabolic pathways, including glycolysis, the citric acid cycle, and the electron transport chain. Through these processes, a total of 38 ATP molecules are generated per molecule of glucose. This ATP production is a result of the energy released from the breakdown of glucose and the transfer of electrons in the electron transport chain.

How is fiber vitamins minerals and water important to the body and what are some examples of foods they are found in?

Fiber helps with digestion and heart health, vitamins and minerals support various bodily functions, and water is essential for hydration and keeping bodily systems functioning properly. Foods high in fiber include fruits, vegetables, and whole grains; vitamins and minerals can be found in a variety of foods such as leafy greens, nuts, and fruits; staying hydrated can be achieved by drinking water and consuming water-rich foods like cucumbers and melons.

Is leptin an enzyme?

No, leptin is not an enzyme. It is a hormone produced by fat cells that plays a role in regulating energy balance and appetite.

Which amino acid forms a dimer that help in protein stability?

It would be the amino acid that has sulfur in it's R group because sulfur forms covalent dimers that strongly bond in proteins. Name escapes my memory, but any amino acid that is complete should show you this.

Are teeth made of dead Cells?

You have Enamel of teeth, made of calcium salt 96 % and 4 % organic fibers, Dentin 70% calcium salt and 30% organic fibers (mainly collagen) and cementum with 50% calcium salt and 50 % organic fibers ( mainly collagen ). So there is gradual transition from hard salt to salt plus fiber, making fixing of tooth possible to bone by periodontal ligament fixed with a joint called Gomphosis. So coming to the answer, Enamel, dentin,cementum are dead as they are calcium salt and organic fibers. Only pulp is live and two much live, that, we have to open dental colleges for teeth care. In short teeth are not made of dead cells.

What happens to mRNA when it leaves a ribosome?

Once mRNA leaves a ribosome, it can be degraded by cellular enzymes or recycled for further rounds of translation. It may also undergo additional modifications, such as polyadenylation, to stabilize or target it for degradation. Ultimately, the fate of mRNA depends on various factors within the cell.

How are alcholic and lactic acid fermentation different?

lactic acid fermentation helps make yogurt, cheese, and it also occurs in muscles which is why you may get that burning sensation in your legs while excersizing. Alcoholic fermentation makes wine and bread using yeast.

What play many key roles in the manufacture of proteins?

Ribosomes are a crucial component in the manufacture of proteins, as they are responsible for translating the genetic code from mRNA into a specific sequence of amino acids. Transfer RNA molecules also play a key role by bringing the correct amino acids to the ribosome during protein synthesis. Additionally, enzymes and various factors are involved in the regulation and coordination of protein synthesis within a cell.

Why does extra glucose and oxygen let muscles pull harder?

The reaction of glucose with oxygen, which is equivalent to burning, but slower, releases energy which drives every other chemical reaction of the body, including those which cause muscle fibers to contract.

Does RNA look like ladder cut in half?

Yes, RNA can adopt a secondary structure known as a "hairpin loop" in which it can appear similar to a ladder cut in half. This structure forms when regions within the RNA strand pair up with complementary bases, leading to a distinctive double-helix shape with a loop at the end.

How old is Many Heffley?

Manny Heffley, the youngest sibling in the "Diary of a Wimpy Kid" series, is referred to as a toddler. His exact age is not specified in the books, but he is portrayed as being around 2-4 years old.

What hormone are parathyroid hormon?

Parathyroid hormone is a hormone produced by the parathyroid glands. It plays a crucial role in regulating calcium and phosphorus levels in the body by stimulating the release of calcium from bones, increasing calcium absorption in the intestines, and reducing calcium excretion in the kidneys. Maintaining proper levels of parathyroid hormone is essential for bone health and overall mineral balance in the body.

What is carried from parent to offspring on chromosomes?

Genetic information, in the form of genes, is carried from parent to offspring on chromosomes. Genes contain instructions for various traits and characteristics that are passed down from generation to generation. Chromosomes are made up of DNA and contain the genetic material that determines an individual's inherited traits.

What is the function of oxegyn in the electron chain transport?

Oxygen functions as the final electron acceptor in the electron transport chain. It combines with electrons and protons to form water, allowing the transfer of electrons to produce ATP. This process is essential for cellular respiration and generating energy for the cell.
