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.

The style connects the stigma to the ovary, allowing pollen to travel to the ovules.

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.

Nitrogen makes up about 78% of the Earth's atmosphere, making it the primary gas.

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.

Activated charcoal primarily adsorbs substances through physical adsorption due to its high surface area and porous structure.

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.

In carbon dioxide, carbon has an oxidation state of +4.

In FeCl3, iron (Fe) has a primary oxidation state of +3.

In lead(II) oxide, lead has an oxidation state of +2.

In ammonia, nitrogen has an oxidation state of -3.

In nitric acid, nitrogen has an oxidation state of +5.

In V2O5, vanadium has an oxidation state of +5.

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.

Adsorption primarily involves physical attraction between the adsorbate and the surface of the adsorbent.

Adsorption of gases on solid surfaces primarily occurs due to Van der Waals forces, which are weak intermolecular forces that allow gas molecules to adhere to the surface.
