Cruciferous vegetables like broccoli and kale are rich in antioxidants that may reduce cancer risk.

Progesterone is the primary hormone responsible for maintaining pregnancy.

Auxins are the primary hormones that promote cell elongation, particularly in stems.

Estrogen is the primary hormone that regulates the menstrual cycle, influencing the growth and maintenance of the endometrium.

Cytotoxic T cells are primarily responsible for recognizing and killing virus-infected cells.

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

Natural selection is the primary mechanism of evolution, favoring traits that enhance survival and reproduction.

Natural selection is the primary mechanism of evolution, where advantageous traits become more common in a population.

Active transport is the primary mechanism for nutrient absorption in plant roots, allowing plants to uptake minerals against their concentration gradient.

Natural selection is the process through which species adapt to their environment, leading to evolutionary changes over generations.

Antigenic drift refers to the gradual mutation of viral antigens, allowing the influenza virus to evade the host's immune response.

Vaccines stimulate the immune response by introducing antigens, which prepare the immune system to recognize and fight the actual pathogen.

Alcohol-based disinfectants primarily work by denaturing proteins, which disrupts cellular functions and leads to cell death.

Chlorine acts as an oxidizing agent, damaging cellular components and leading to microbial death.

Chlorine-based disinfectants primarily act by denaturing proteins, which disrupts cellular functions.

Ethylene oxide primarily acts by denaturing proteins, which disrupts cellular functions and leads to microbial death.

Glutaraldehyde acts primarily by denaturing proteins, which leads to the inactivation of microorganisms.

Quaternary ammonium compounds primarily act by disrupting cell membranes, leading to cell lysis and death of the microorganism.

Fragmentation is a common method of asexual reproduction in plants where a part of the plant breaks off and develops into a new individual.

Strawberry plants primarily reproduce asexually through runners, which are horizontal stems that grow along the ground and produce new plants.

The primary method of classification used in modern botany is genetic classification.

Bryophytes primarily reproduce through spores, which are produced in specialized structures called sporangia.

Dandelions use wind dispersal, with their lightweight seeds attached to parachute-like structures.

Most mammals reproduce viviparously, meaning they give birth to live young rather than laying eggs.

Most reptiles primarily reproduce through egg-laying, which is a characteristic of their reproductive strategy.

Hepatitis B virus is primarily transmitted through blood and bodily fluids, making it a bloodborne pathogen.

The influenza virus is primarily transmitted through airborne droplets when an infected person coughs or sneezes.

The diaphragm is the primary muscle involved in inhalation, contracting to increase the volume of the thoracic cavity and draw air into the lungs.

The diaphragm contracts and moves downward, increasing the thoracic cavity volume and allowing air to flow into the lungs.

The sinoatrial (SA) node is the primary pacemaker of the heart, initiating the heartbeat.
