Angiosperms, or flowering plants, are considered the most evolutionarily advanced due to their complex reproductive structures.

Ferns exhibit a dominant sporophyte generation, which is the diploid phase that produces spores.

Abscisic acid is the hormone that signals stomata to close in response to water stress, reducing water loss.

Oxytocin is the hormone that stimulates uterine contractions, leading to labor.

Progesterone is crucial for maintaining the uterine lining and supporting early pregnancy.

Insulin is the hormone that regulates blood sugar levels by facilitating the uptake of glucose into cells.

Estrogen plays a key role in regulating the menstrual cycle, particularly in the follicular phase.

Gastrin is the hormone that stimulates the secretion of gastric acid, aiding in digestion.

B and T lymphocytes are the main components of the adaptive immune response, responsible for specific recognition and memory.

Cytotoxic T cells are primarily responsible for recognizing and killing cells infected with intracellular pathogens, such as viruses.

Eosinophils play a key role in the immune response against helminth infections, as they are involved in the destruction of larger parasites.

B and T lymphocytes are the key players in the adaptive immune response, providing specific immunity against pathogens.

Cytotoxic T cells are responsible for directly killing virus-infected cells.

Cell-mediated immunity, particularly through cytotoxic T cells, is crucial for targeting and eliminating virus-infected cells.

IgA is the main immunoglobulin found in mucosal areas, providing protection against pathogens at mucosal surfaces.

IgE is the immunoglobulin primarily involved in allergic reactions and responses to parasitic infections.

IgM is the first immunoglobulin produced in response to an infection, providing an early defense against pathogens.

The ELISA test is commonly used to detect antibodies against HIV, indicating infection.

A rapid antigen test is commonly used to quickly diagnose streptococcal pharyngitis (strep throat).

The rapid antigen detection test is commonly used to quickly diagnose streptococcal pharyngitis by detecting Group A Streptococcus antigens.

Using cuttings is a form of asexual reproduction where a part of the plant is used to grow a new individual.

Asexual reproduction, such as cuttings or grafting, allows farmers to produce genetically identical plants with desirable traits.

Penicillium chrysogenum is the mold from which the antibiotic penicillin is derived, used to treat bacterial infections.

Saccharomyces cerevisiae, or baker's yeast, is responsible for the fermentation process in bread making.

Lactobacillus species are key players in the fermentation process of sauerkraut, converting sugars into lactic acid.

Saccharomyces cerevisiae, or baker's yeast, ferments sugars to produce carbon dioxide and alcohol, causing bread to rise.

Acetobacter is a genus of bacteria that converts ethanol into acetic acid, the main component of vinegar.

Vibrio cholerae is the bacterium that causes cholera, a severe diarrheal disease often linked to contaminated water.

Mycobacterium tuberculosis is the causative agent of tuberculosis, a serious infectious disease that primarily affects the lungs.

Polymerase chain reaction (PCR) is a technique used to amplify a specific DNA segment, making millions of copies of it.
