7 0

DNA Mutation is caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes. Thus, the correct answer is option D.

1.DNA Mutations are caused by environmental factors known as mutagens.

2.Types of DNA mutagens include radiation, chemicals, and infectious agents.

3.DNA Mutations may be spontaneous in nature.

The answer would be syllogism. This is a type of logical argument that applies deductive reasoning to get an outcome grounded on two or more suggestions that are declared or supposed to be true. Example: All mammals are warm-blooded. Therefore, all brown dogs are warm-blooded.

An infant has a strange rash. Some of the rash is swabbed and examined under the microscope. A mass of threadlike structures is observed. So, this infection be treated with an anti-fungal cream

OTC creams will deal with the infection (e.g., Lamisil, Lotrimin, Micatin, Tinactin), however, in some cases oral drugs are fundamental.

In infants, Fungi can cause superficial infection, i.e., on skin, nails, and hair like oral thrush, candida diaper rash, fungal infection, and so forth, are different kinds of superficial fungal infections, subcutaneous contagious disease in tissues under the skin and finally it causes systemic infection in more profound tissues.

The primary structure of most fungi consists of fine, spreading, normally dull threads like structures called hyphae. Every fungus will have immense quantities of these hyphae, all interlacing to make up a tangled web called the mycelium.

In the combined processes of glycolysis and cellular respiration, what is consumed and what is produced?.

IrinaVladis [17]

Glucose is consumed and carbon dioxide is produced during the combined processes of glycolysis and cellular respiration.

Glucose is a simple sugar. Glucose is the most common monosaccharide, a type of carbohydrate. Glucose is primarily produced by plants and most algae during photosynthesis from water and carbon dioxide with the help of sunlight, where it is used to produce cellulose in cell walls, the world's most abundant carbohydrate.

A glucose molecule is gradually broken down into carbon dioxide and water during cellular respiration. Some ATP is produced directly along the way in the reactions that transform glucose. However, much more ATP is produced later in the process known as oxidative phosphorylation. The movement of electrons through the electron transport chain, a series of proteins embedded in the inner membrane of the mitochondrion, drives oxidative phosphorylation.

During glycolysis, a six-carbon sugar, glucose, undergoes a series of chemical transformations. It eventually degrades into two molecules of pyruvate, a three-carbon organic molecule. ATP is produced in these reactions.
