The primary function of the root system is to anchor the plant and absorb water and nutrients from the soil.

The rough endoplasmic reticulum is studded with ribosomes and is primarily involved in the synthesis of proteins.

The primary function of the skeletal system in locomotion is to provide a framework for muscle attachment, enabling movement.

The skeletal system serves multiple functions including movement, protection of vital organs, and mineral storage.

The primary function of the small intestine is the absorption of nutrients from digested food.

Surfactant reduces surface tension in the alveoli, preventing their collapse and aiding in gas exchange.

Thyroid hormones, primarily thyroxine (T4) and triiodothyronine (T3), are crucial for regulating metabolism in the body.

White blood cells are part of the immune system and are primarily responsible for fighting infections and foreign invaders.

The primary goal of gene therapy is to replace defective genes in order to treat or prevent diseases.

The primary goal of sustainable development is to meet the needs of the present without compromising the ability of future generations to meet their own needs.

Nutrients in phloem are primarily transported by bulk flow, which is driven by pressure differences.

Charles Darwin proposed the mechanism of evolution known as Natural Selection, which explains how species adapt and evolve over time based on environmental pressures.

Bacteria primarily reproduce asexually through binary fission, where a single cell divides into two identical cells.

The primary mode of nutrition in the kingdom Animalia is heterotrophic.

Plants primarily exhibit autotrophic nutrition through photosynthesis.

Angiosperms primarily reproduce through sexual reproduction, involving flowers and seeds.

Ferns primarily reproduce through sexual reproduction, producing spores.

Unicellular organisms primarily reproduce asexually, often through processes like binary fission.

The diaphragm is the primary muscle that contracts and relaxes to facilitate breathing.

Particulate matter is a primary pollutant in smog, contributing to air quality issues.

Photosynthesis is the primary process by which energy from sunlight is converted into chemical energy by plants.

Algae are the primary producers in a freshwater ecosystem as they perform photosynthesis.

Reproduction ensures the continuation of a species by producing offspring.

Reproductive health education aims to inform individuals about safe practices, including the prevention of sexually transmitted diseases.

Recombinant DNA technology is used to create vaccines, produce antibiotics, and synthesize hormones like insulin.

Restriction enzymes are proteins that cut DNA at specific sequences, which is essential for cloning and genetic engineering.

The increase in human population is attributed to a combination of increased birth rates, decreased death rates, and improved healthcare.

Gibberellins promote enzyme production that breaks down stored food in seeds, facilitating germination.

Potassium plays a crucial role in water regulation and osmotic balance in plants, helping to maintain turgor pressure.

Root hairs increase the surface area for water absorption from the soil.
