Oleic acid molecules are cubic in shape where a side of the cube is the height of the monolayer, the area of oleic acid molecule is 6h².

The total amount of space occupied by a place surface is the area of a specific shape.

Area often refers to a solid object's shape or two dimensions.

A three-dimensional object known as a cube has six faces with equal surface areas.

A cube's total area is calculated by summing the findings of the areas of each of its six faces.

A cube's total surface area equals 6 * \(a^{2}\).

Where an is any one of the six faces' region.

Oleic acid molecules have a cubic form, with the height of the monolayer being one of its sides.

Let h represent the height of the oleic acid.

By dividing the square of the molecule's height by six, the area of an oleic molecule can be calculated.

Molecule size of oleic acid is 6 * \(h^{2}\).

Explanation:

Proteins can be disassembled into their individual amino acids while fasting, which the body can subsequently utilise for a variety of functions.

The generation of free fatty acids from amino acids in the liver through a process known as gluconeogenesis is one of the fates of proteins in the fasting state. This happens when the body's glucose reserves are depleted and the body must turn to alternative energy sources, such lipids. Deamination of amino acids in the liver, which eliminates the amino group and generates ammonia and other byproducts, is another way that proteins are broken down. The amino acids' residual carbon skeletons can be utilised for gluconeogenesis and other metabolic activities.

Warm and moist conditions are the most ideal for decomposition of organic matter and decay of food instead of cool and dry places.

Food spoilage is a result of both natural food degradation and contamination from microbes including bacteria, moulds, and yeasts. When moisture and desired temperatures are present, these breakdown bacteria may proliferate quickly.

An exponential rise in decomposition rates is caused by rising temperature under ideal moisture conditions.

Warm and moist places facilitate growth of detritivores like bacteria and fungus which are saprophytic and degrade the organic matter and decay the food stored in such places. Detritivores favour warm and moist conditions over cool and dry conditions for their growth.

Decomposition is the process of decay and degradation or breakdown of organic matter by bacteria and fungi into smaller substances.

Answer:

Explanation:

DNA, or deoxyribonucleic acid, is the molecule that stores and transmits genetic information in all living organisms. Genetic information is stored in the sequence of nucleotides, the building blocks of DNA. Each nucleotide is made up of a sugar, a phosphate group, and a nitrogenous base. There are four types of nitrogenous bases in DNA: adenine (A), thymine (T), guanine (G), and cytosine (C).

The specific sequence of these bases along the DNA strand is what encodes the genetic information. For example, the sequence ATGCAGA might code for a specific protein, while the sequence GACATAG might code for a different protein. These sequences of bases are stored in specific regions of the DNA called genes.

The genetic information is transmitted during cell division, when the DNA is replicated, and during protein synthesis, when the information in the DNA is used to build the specific proteins determined by the genetic code.

In the absence of glucose, the lac operon in bacteria can be activated by the presence of lactose. When lactose is present, it is converted to allolactose which binds to the lac repressor, causing it to release from the operator site.

This allows RNA polymerase to bind to the promoter and transcribe the genes involved in lactose metabolism. The CAP-cAMP complex is also involved in regulating the lac operon. When glucose levels are low, cAMP levels rise, and the complex binds to the promoter region, increasing RNA polymerase's affinity for the promoter and further enhancing transcription.

Answer:

The process of meiosis involves cell division in which results in 4 daughter cells. Each cell has half the number of chromosomes of the parent cell. Genes are what determine what each cell obtains. A  unit of genes is transferred from a parent to offspring. In some cases they are spreaded equally among the eggs therefore creating identical twins. While in other cases they are not distributed in variation, creating fraternal twins.

The two girls in the images do not look identical due to there being two separate eggs that were fertilized by the sperm. Independent assortment causes genes to separate from each other when reproductive cells develop. Variation defines the difference between the DNA in two individuals. Crossing over happens when the exchange of genes between homologous chromosomes results in parental mixture to the offspring. When this occurs, the genes are uniquely developed between the two eggs.

As you can see, the methodology for the making of two non-identical twins posses a series of steps. A variation of features is created due to genes determined by independent assortment. Meiosis is what divides the cells into daughter cells for fertilization by the sperm. All of which was talked about holds a great purpose in the process.
