Introduction to Biology

The scientific study of bacteria is called bacteriology, which is a branch of microbiology. Since bacteriology is not listed among the options, 'none of these' is the correct choice.

Louis Pasteur is widely recognized as the father of microbiology for his work on germ theory and pasteurization.

Antonie van Leeuwenhoek is famous for his pioneering work using simple, single-lens microscopes of his own design.

Ronald Ross received the Nobel Prize in Physiology or Medicine in 1902 for his work on malaria transmission.

Neutral fats, also known as triglycerides, are commonly found in oils and animal fats.

The normal concentration of sodium chloride in human blood is approximately 0.9 percent by mass, which translates to about 900 mg per 100 ml, not the incorrect figures listed in options A through C. Thus, none of the provided numerical options are accurate.

Biological death is the permanent cessation of all biological functions that sustain a living organism, which is the standard definition for legal death.

Sucrose is a disaccharide, meaning it is composed of two monosaccharides (glucose and fructose), hence it is called a double sugar.

AIDS is caused by the HIV virus, which is transmitted through direct contact with certain body fluids, primarily blood, semen, and vaginal secretions. It is not spread through air or dust.

The scientific study of snakes is known as ophiology or herpetology. Because neither of these terms appears in the choices, none of these is the correct answer.

Limulus, commonly known as the horseshoe crab, is a classic example of a living fossil because it has remained largely unchanged for millions of years.

Parasitology is the branch of biology or medicine concerned with the study of parasitic organisms and their hosts.

Cardiology is the medical specialty that deals with disorders of the heart and the cardiovascular system.

Fritz Lipmann is widely recognized for his work on the discovery of coenzyme A and his contributions to understanding the ATP cycle in cellular metabolism.

Hydrophobia is a term derived from Greek meaning fear of water. It is also a historical name for rabies, as infected individuals often have difficulty swallowing water.

The biogenetic law, which famously states that ontogeny recapitulates phylogeny, was proposed by the German biologist Ernst Haeckel. Option C contains a slight spelling variation (Hacckle), but it clearly refers to him.

Body temperature is primarily regulated by the hypothalamus, a structure located within the brain. It acts as the body's internal thermostat.

Wendell Meredith Stanley was an American biochemist and virologist who is known for his work on the crystallization of the tobacco mosaic virus, often cited as a pioneer in virology.
