Ehrlich: Paul Ehrlich is known for his work in immunology and for developing the concept of a "magic bullet" in chemotherapy, as well as discovering Salvarsan for treating syphilis, but he was not involved in the discovery of penicillin.

Pasteur: Louis Pasteur made groundbreaking contributions to microbiology and germ theory, including pasteurization and vaccines for rabies and anthrax.

Lister: Joseph Lister pioneered antiseptic surgery and promoted the use of carbolic acid to prevent infections during surgical procedures, but he did not discover penicillin.

Louis Pasteur: Louis Pasteur made significant contributions to microbiology and germ theory, including the development of pasteurization and vaccines, but he did not specifically establish hygiene standards in healthcare settings.

Robert Koch: Robert Koch is known for identifying the causative agents of diseases such as tuberculosis and anthrax and developing Koch’s postulates, but he focused on microbiology research rather than hygiene practices in hospitals.

Rudolf Virchow: Rudolf Virchow contributed to cellular pathology and emphasized the importance of social and environmental factors in disease, but he did not establish hygiene standards in clinical care.

Order of complexity: Order of complexity refers to the organized structure of living systems, from molecules to cells to organisms. While organization is important, it does not directly describe the ability to respond to a stimulus.

Evolution: Evolution involves gradual genetic changes in populations over generations. It explains long-term adaptation but does not account for an immediate response to a stimulus by an individual organism.

Homeostasis: Homeostasis is the maintenance of internal stability, such as temperature or pH, despite external changes. While it can involve responses, it specifically refers to regulation rather than reacting to a particular stimulus.

Determine the type of yeast that would produce the best tasting wine: This relates to fermentation studies, particularly those of Louis Pasteur, rather than Koch’s postulates, which focused on linking specific microbes to specific diseases.

Determine why milk spoils: Milk spoilage investigations are associated with Pasteur’s work on microbes and pasteurization. Koch’s postulates were designed to establish causation between microbes and disease, not food preservation.

Disprove spontaneous generation: Disproving spontaneous generation was a key goal of Pasteur’s experiments using sterilized broths and flasks. Koch’s postulates, in contrast, provided a method to prove microbial causes of disease.

The process of producing more cells: Producing more cells describes cell division or growth, which increases the number of cells but does not encompass the overall progression toward a mature form.

The process of producing larger cells: Increasing cell size is a part of growth at the cellular level but does not capture the broader concept of development involving structural and functional changes over time.

The process of responding to environmental changes: Responding to environmental changes refers to sensitivity or adaptation, which helps an organism survive but is separate from the developmental process.

Collect data: Collecting data occurs after observations are made and experiments are conducted. It is essential for analysis but is not the initial step in the scientific method.

Draw conclusions: Drawing conclusions comes at the end of the scientific method, after analyzing data and determining whether the hypothesis is supported. It is a final step rather than the first.

State a hypothesis: Stating a hypothesis follows making observations. A hypothesis is an educated prediction based on prior knowledge or observed patterns, but it cannot be formulated before initial observations.

Enzymes are made of protein: Enzymes are primarily composed of protein molecules that fold into specific three-dimensional shapes, enabling them to catalyze biochemical reactions efficiently.

Enzymes can be denatured: Enzymes can lose their functional shape, or become denatured, when exposed to extreme temperatures, pH levels, or chemical agents, which impairs their catalytic activity.

Enzymes can be found in biological organisms: Enzymes are naturally present in all living organisms, where they facilitate essential metabolic and physiological processes.

A compound that removes H+ ions from a solution: This describes a base, since bases decrease hydrogen ion concentration by binding or neutralizing H+ ions, which is the opposite of what acids do.

A compound that releases OH- ions into a solution: This also characterizes a base, such as sodium hydroxide, which increases hydroxide ion concentration rather than contributing hydrogen ions.

Aquatic: Aquatic refers to environments or organisms related to water, but it does not describe a chemical process in which bonds are broken.

Dehydration (or condensation): Dehydration involves removing water to form covalent bonds between molecules, which is the opposite of hydrolysis and results in larger compounds.

Hydratic: Hydratic is not a recognized term in chemistry for describing bond-breaking reactions, and it does not apply to hydrolytic processes.

An enzyme speeds up a chemical reaction in living organisms: Enzymes function as catalysts by lowering the activation energy needed for reactions, allowing biological processes to occur more quickly and efficiently.

An enzyme is a biological catalyst: Enzymes are proteins that serve as catalysts in living systems, regulating the speed of biochemical reactions without being permanently altered.

An enzyme is specific to the chemical reaction it catalyzes: Enzymes have a highly specific active site that matches particular substrates, making them selective for certain reactions or molecular interactions.
