Carrots that have been cut into pieces have a shorter
shelf life than whole carrots. Explain this observation
using factors that affect rate of reaction.

Science 10

Answers

Answer 1
When you cut up the carrot you increase the surface area of the carrot substantially. This increased surface area reacts with the atmosphere and makes the carrot (collectively the pieces) more exposed to bacteria and as a result the cut up carrots will go bad before the carrots as a whole.

what are 5 functions of carbohydrates ​

Answers

☁️ Answer ☁️

PROVIDES INSTANT ENERGY TO THE BODY:

This appears to be the primary function of carbohydrates in the body.

Carbohydrates which we consume as food in the form of starch (ex: potato, bread), sucrose (ex: sugar, fruits), etc. get digested in the body to release glucose.

RESERVE FOOD:

Carbohydrate is also stored as the reserve food in the body. This is a precautionary measure for the body to cope up in times of hunger.

CARBOHYDRATES FORM OTHER BIOMOLECULES:

Carbohydrates in excess are converted into other bio-molecules of physiological importance. They mostly get stored in the form of fats.

DETOXIFICATION OF THE BODY BY METABOLISM:

Many drugs and toxic wastes in the body are metabolized for easy excretion in the body.

SPARING PROTEIN

In a situation where there is not enough glucose to meet the body’s needs, glucose is made from amino acids. Because there is no storage molecule of amino acids, this process requires the destruction of proteins, primarily from muscle tissue. The presence of adequate glucose basically spares the breakdown of proteins from being used to make glucose needed by the body.

DNA and RNA are made of what monomers? ___________________________
42. What are the 3 components of a nucleotide? ________________________________________
43. What are the elements found in nucleic acids?___________________________________
44. What are the 3 polymers for nucleic acids.________________________________________
45. What are the 2 main functions for nucleic acids.________________________________________________________________________

Answers

Answer:

42. Nucleotides are composed of three subunit molecules: a nucleobase, a five-carbon sugar (ribose or deoxyribose), and a phosphate group consisting of one to three phosphates. The four nucleobases in DNA are guanine, adenine, cytosine and thymine; in RNA, uracil is used in place of thymine

Explanation:

43.Nucleic acids contain the same elements as proteins: carbon, hydrogen, oxygen, nitrogen; plus phosphorous (C, H, O, N, and P). Nucleic acids are very large macromolecules composed of repetitive units of the same building blocks, nucleotides, similar to a pearl necklace made of many pearls.

44.polymer of nucleic acid

33 terms. The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Threose nucleic acid (TNA) is an artificial genetic polymer in which the natural five-carbon ribose sugar found in RNA has been replaced by an unnatural four-carbon threose sugar.
