The flattened stems of a cactus, also known as the pads or cladodes, are adapted for photosynthesis. These pads have a large surface area that allows for increased sun exposure, while the waxy coating helps reduce water loss. Additionally, the presence of specialized cells called chloroplasts within the pads enables photosynthesis to occur efficiently in these plants.

in DNA estimation by diphenylamine method, standard calf thymus DNA is digested by perchloric acid, but unkown is not digested by perchloric acid, rather rest protocol of diluting with water and treating with diphenylamine and checking aborbance reamins same can anybody say the reason?

Benedict's test is based on Benedict's reagent, a liquid that changes color based on the sugar content of the material put in. Ketohexose acts as a reducing sugar because benedict's reagent is comprised of sodium citrate, sodium carbonate, and cupric sulfate. The cupric sulfate reacts with the ketohexose, reducing it and causing it to precipitate as cuprous oxide, which is what changes the color of the reagent and determines the sugar content.

People are at higher risk for deficiency if they have poor nutritional sources of B vitamins, take medications, or have conditions that impair absorption, or are affected by circumstances causing them to require above-normal levels of vitamin B

According to Chargaff's rules, the percentage of adenine is equal to thymine in a double-stranded DNA molecule. These rules state that in DNA, the amount of adenine is equal to the amount of thymine, and the amount of guanine is equal to the amount of cytosine.

Yes, in the case of an operon encoding enzymes for making an essential amino acid and regulated like the trp operon, the amino acid would act as a corepressor. When the levels of the amino acid are sufficient, it can bind to the repressor protein, allowing it to bind to the operator region of the operon, thereby blocking transcription of the genes involved in amino acid biosynthesis.

Sudan IV dye is a fat-soluble dye that binds to lipids in a solution. When lipids are added to Sudan IV dye, the dye molecules bind to the lipids and cause them to appear redish brown in color. This is a characteristic reaction that helps to identify the presence of lipids in a substance.

DNA is organized in a double-helix fashion.

No, plants carry out photosynthesis because they contain chloroplasts, not mitochondria. Chloroplasts are the organelles responsible for photosynthesis, while mitochondria are responsible for cellular respiration.

well to be honest a benefit could be that less people are having sexual intercourse and dont need to worry about a feotus growing. however, this could be a problem and people could over use the pill and overdose themselves and find themselves in trouble

We can not extract DNA from RBCs as they are without nucleus. only the source of DNA extraction is Leukocytes,

RBCs are not good source of extraction but we can extract DNA from immature RBCs.

Salicylates are commonly used as pain relievers, fever reducers, and anti-inflammatory agents. They are often found in medications used to treat conditions such as headaches, arthritis, and muscle aches. Salicylates can also be used topically to help with skin conditions such as psoriasis and acne.

Although these drugs are less effective than the statins at lowering total cholesterol, they may be able to lower the low-density lipoprotein (LDL) cholesterol while raising the high-density lipoprotein (HDL) cholesterol.

Enzymes are very important because they speed up the chemical reactions that are required for life. Enzymes are organic catalysts and they facilitate the chemical reaction in human body like digestion and respiration.They maintain the homeostasis in human body.

Non-polar molecules are more likely to float in water because they are hydrophobic (water-repelling) and do not readily mix with water. Examples include oil, fats, and waxes. Due to the lack of polarity, these molecules are less dense than water and tend to float on its surface.

Meosis 1(1st stage)

2 daughter cells are formed with each daughter containing only one chromosome of the homologous pairs thus containing haploid no. of chromosomes each.

Meiosis II(2nd stage) is similar to mitosis.

DNA does not replicate

Chromosomes align at the equatorial plate.

Centromeres divide and sister chromatids migrate separately to each pole.

Four haploid daughter cells are obtained.

Elements that are likely to be lost by dry ashing include volatile elements such as mercury, arsenic, and selenium. These elements can evaporate or sublime at the high temperatures used during dry ashing, leading to their loss from the sample.

No, ethanol is not a holoenzyme. Ethanol is a type of alcohol that can act as a substrate or inhibit the activity of enzymes in biological systems. Enzymes are protein molecules that act as catalysts to facilitate specific chemical reactions in living organisms.

In the post-absorptive state, glucagon is released from the pancreas. Glucagon helps increase blood sugar levels by promoting the breakdown of glycogen in the liver and stimulating gluconeogenesis.

A frame-shift mutation.

1 kilogram = 1000 grams. You can now work out the answer easily.

You can also use epsom salts to clear up acne... make a strong solution (3 T to 1 1/2 c hot water) and soak a face towel in it. Wring it out and place on your face for up to 20 minutes twice a day. You can also use it in the bath (18oz per tub) and soak in it at least 30 minutes a day for body acne.

I've also made the hot towel and sprinkled extra salts on the surface, folded the towel to begin gently dissolving the salts and then opened it back up and placed it on my forehead to clear up blemishes.

Epsom salt. There are tons of ways to use it to feel better, even toenail fungus! http://www.ehow.com/how_4933618_use-salt-toenail-fungus-treatment.html Also works great to fertilize flowers and plants! http://www.ehow.com/how_5016008_grow-flowers-epsom-salt.html Kathy

Gasoline is considered an organic material because it is derived from crude oil, which is a naturally occurring organic compound formed from the remains of living organisms. Organic materials are generally defined as compounds containing carbon atoms, and gasoline falls under this category.
