substitution is not a missense mutation.

A genetic modification in which the genetic code is altered by a single base pair substitution, producing an amino acid that is different from the usual amino acid at that position. Certain missense variants (or mutations) alter a protein's functionality.

In terms of genomics, substitution is a sort of mutation where one nucleotide is changed for a different nucleotide. The phrase can also be used to describe switching out one amino acid for another in a protein.

A frequent and well-known example of a missense mutation is the blood condition sickle-cell anaemia. Missense mutations exist in the DNA at a single location in sickle-cell anaemia patients. A different amino acid is required in this missense mutation, which also alters the overall structure of the protein.

Leaf colour varies from a deeper to a lighter shade of green when maintained in the dark because leaves need light to accomplish photosynthesis. It can also become yellow occasionally.

The amount of light present has a direct correlation with the formation of the pigment chlorophyll, which is necessary for photosynthesis.

Because of this, the light that is reflected by the leaves is less red and blue and appears green instead. Actually, there are two pigments that make up chlorophyll: chlorophyll a and chlorophyll b.

The procedure for a change in leaf colour. The number of pigments changes as the leaves get ready to fall from the trees, which causes the colour of the leaves to alter in the autumn. Throughout the growth season, all leaves gradually lose chlorophyll, and this loss quickens before leaf fall.

To solve this we need to know the roots of the words we are given. "Anti" we know means to inhibit or stop. Fungal refers to fungus, biotic refers to bacteria, and viral refers to viruses. This leaves the root "Pruritic " for us to figure out. By process of elimination, this is of course our answer, but we need to know and recognize that the word "Pruritis" means itching. Therefore antipruritic would refer to something that stops or inhibits itching.

The homologous chromosomes align at the equatorial plate during meiosis of metaphase I. Spindle fibres are connected to homologous chromosomes. The chromosomes align at the equatorial plate during metaphase II of meiosis II, and the spindle fibres bind to the sister chromatids.

Hence, option A is correct.

What do you mean by chromatids?

A chromatid is one half of a chromosome that has been duplicated. One chromosome is made up of one DNA molecule before replication. The DNA molecule is copied during replication, and the two molecules are known as chromatids. These chromatids divide longitudinally to form distinct chromosomes during the latter stages of cell division. Normally, chromosome pairs are genetically identical and referred to be homozygous. However, if mutations occur, they will show minor changes, indicating that they are heterozygous.

According to the law of acceleration, an object's acceleration increases as its mass decreases while its force remains constant.

Newton's law explains how the relationship between the force, mass, and acceleration works.

Mass times acceleration equals force. The mass is inversely proportional to the acceleration, according to the equation.

According to the second law, the mass of the item and the net force acting on it both affect how quickly an object accelerates. An object's acceleration is directly proportional to the net force applied on it and inversely proportional to its mass.

Stimulates cells to break down glycogen into glucose is Glycogenolysis.

Glycogenolysis is a mechanism that converts glycogen, the major carbohydrate stored in animal liver and muscle cells, into glucose in order to provide energy quickly and keep blood sugar levels stable during fasting. Glucagon and epinephrine, two hormones that are largely found in the liver and that induce glycogenolysis (adrenaline).The pancreas secretes more glucagon when blood glucose levels drop, like they do when you fast. Since the activities of insulin, which are intended to enhance the storage of glucose in the form of glycogen in cells, work against the actions of glucagon, this rise is accompanied by a concurrent reduction in insulin production. Glucagon is secreted, then it moves to the liver to activate glycogenolysis.

In surface science, the development of menisci is frequently employed to calculate contact angles and surface tension.

The menisci's form is assessed via a contact angle measurement using a balance or visually using a digital camera. When measuring surface tension, the measurement probe has a contact angle of zero, and the meniscal mass may be used to determine the surface tension. Usual equipment for this is a Wilhelmy plate.

Surface tension causes a liquid's upper surface to bend toward the surface of a container or other object, creating a meniscus.

The expected ratio of purple flowered PP and [tex]P_{p}[/tex] to white flowered pp offspring is 51:12

Mendel examined a pea plant's various characteristics. As an illustration, some pea plants have white blossoms while others have purple flowers. Pea plants have the option of self- or cross-fertilization and produce offsprings. Hybridization is the process of crossing two plants. Mendel required true-breeding plants to begin with, though. This indicates that the pea plant only exhibited one variation of the characteristic following generations of self-breeding. After several generations, a plant with purple flowers exclusively produced purple flowers; it never produced a plant with white flowers. Then endel crossed a purple flowering plant that was true to breed with a white flowering plant. This is called a monohybrid experiment. The result of a test cross between two plants that breed identically for one attribute is determined for each of the offspring plants.

PP and [tex]P_{p}[/tex] = 25+26=51
