Nucleotides are the subunits of nucleic acids. These monomers are composed of three parts, the base, the phosphate group, and the sugar. In the xposed emage, 1- nucleotide. 2- pyrimidine. 3- purine. 4- phosphate. 5- deoxyribose. 6- Hydrogen bond.

Nucleotides are monomers composed of a sugar molecule, joined with a phosphate group and a nitrogenated base. Many of these monomers comprise nucleic acids, which are polymer.

Monomers are composed of carbon, oxygen, and hydrogen atoms, which establish covalent bonds.

DNA ⇒ Adenine, Guanine, Thymine, and Cytosine.

RNA ⇒ Adenine, Guanine, Uracyl, and Cytosine

Adenine pairs with thymine or uracil, while guanine pairs with cytosine.

DNA sugar group contains deoxyribose

RNA sugar group contains ribose

It is composed of a central phosphoric atom surrounded by four oxygen atoms arranged in a tetrahedron layout.

Nucleotides have a certain order or sequence in nucleic acids, which is significant since these sequences carry biological information necessary to carry out cellular functions.

In the exposed emage, we can see

1- Represents the whole nucleotide.

The decimalized system based on the meter that had been adopted in France in the 1790s was replaced by the metric system, which is a system of measurement.

Including or covering all or a whole collectively or distributively without limit or exception.

A standardized approach that enables international scientists to communicate and compare notes is necessary. Without a standard, they would have to spend extra time converting measurements between different systems of measuring, which would reduce accuracy. SI or metric unit is favoured because, among other things, it is not based on the bodily parts of individuals who lived hundreds of years ago.

Parts of a gene are known as introns and exons in molecular biology. While introns are the non-coding portions that break up coding sequences, exons are the coding areas of a gene that carry the information required to construct a protein.

Introns are not expressed, whereas exons are the regions of a gene that are. Introns are cut out and exons are spliced together to create the final messenger RNA (mRNA) which will be translated into a protein after a gene has been transcribed into mRNA.

Mendel's model of genetics is not the only model of inheritance, because may be another model, was also presented by another scientist.

The Mendelian quality is determined by dominant and receding alleles of one gene. On the opposite, non-Mendelian traits are not determined by dominant and relapsing alleles and can be governed by more than one gene. Non-Mendelian inheritance is any design in which traits do not segregate in accordance with Mendel's laws.

The genetic traits that follow the truth of Mendel's law are known as Mendelian inheritance while the genetic traits. Non-Mendelian genetics are inheritance motif that is different from Mendelian inheritance.

Circulatory system and respiratory system work together so oxygen can be distributed to the cells of your body.

The circulatory and respiratory systems collaborate to move blood and oxygen around the body. The trachea, bronchi, and bronchioles transport air into and out of the lungs. The pulmonary arteries and veins connect to the heart and transport blood into and out of the lungs.

To obtain oxygen, blood travels from the heart to the lungs. The respiratory system includes the lungs. The exchange of gases between tissues and blood is a critical function of the circulatory system. Blood absorbs oxygen and emits carbon dioxide in the lungs of humans, other mammals, and birds. Thus, the circulatory and respiratory systems work in tandem to obtain oxygen and expel carbon dioxide.

DNA and RNA hold the code to create proteins that are the key to gene expression demonstrates the central dogma of molecular biologists.

The basic idea of molecular biology describes how genetic material goes from DNA to RNA to create a protein, which is an important final result. The central dogma is that RNA acts as a messenger, carrying information from the DNA to the ribosomes, where it is utilised to make all of our proteins.

Ribosomes serve as factories in the cell where information is "transformed" from a code into a useful part. The process by which the DNA instructions are converted into a usable product is known as gene expression. The two critical stages of gene expression are transcription and translation. Every cell's DNA includes information that, during transcription, is converted into succinct, transportable RNA messages.

During muscle contraction, if feeling fatigued it means that muscles do not get in the required oxygen to generate ATP causing lactic acid fermentation, hence option c is correct.

A metabolic process called lactic acid fermentation turns six-carbon sugars like glucose or other six-carbon sugar disaccharides like sucrose or lactose into the metabolite lactate.

It generates carbon dioxide as well as lactic and acetic acids, which swiftly reduce pH levels and prevent the growth of bacteria that may otherwise ruin crispness.

Therefore due to anaerobic conditions muscle gate fatigue creates lactic acid fermentation, hence option c is correct.
