Sulfur is essential for the synthesis of amino acids and proteins, playing a critical role in plant metabolism.

Tendons connect muscles to bones, allowing for the transfer of force and movement.

The cell membrane regulates the transport of substances in and out of the cell.

The filament is the stalk that supports the anther, which produces pollen.

The loop of Henle plays a crucial role in the reabsorption of water and salts, helping to concentrate urine.

The lymphatic system is responsible for transporting lymph, which contains immune cells, and helps in the removal of waste products from tissues.

The ovary's primary role in the female reproductive system is the production of eggs (ova) which are necessary for reproduction.

The spleen plays a crucial role in filtering blood and removing old or damaged red blood cells.

The synapse is the junction between two neurons where neurotransmitters are released to facilitate communication.

Synovial fluid serves multiple functions including lubrication, nutrient supply, and shock absorption in joints.

Yeast ferments sugars to produce carbon dioxide, which helps the dough rise in baking.

The root mean square speed (v_rms) of gas molecules is given by the formula v_rms = √(3RT/M), where R is the universal gas constant, T is the temperature, and M is the molar mass.

The scientific name of the domestic cat is Felis catus, following the binomial nomenclature system.

Biology is the scientific study of living organisms.

A tetrahedral geometry has a central atom bonded to four other atoms, forming a shape like a pyramid with a triangular base.

Methane (CH4) has a tetrahedral shape due to the four pairs of bonding electrons around the central carbon atom.

The s orbital has a spherical shape.

Shear modulus (G) = Shear stress / Shear strain = 100 MPa / 0.05 = 2000 MPa.

The SI unit of electric charge is Coulomb (C).

The SI unit of electric current is the Ampere (A).

The SI unit of magnetic moment is Joule per Tesla (J/T), which can also be expressed as Ampere-meter squared (A·m²).

Biodiversity hotspots are significant because they are regions with a high number of endemic species and are under threat from human activities.

Bt cotton is genetically modified to produce a toxin that is harmful to specific pests, reducing the need for chemical insecticides.

Prenatal care is crucial for monitoring the health of both the mother and the developing fetus, ensuring a healthy pregnancy.

Significant figures indicate the precision of a measurement, reflecting the certainty of the digits.

The electron transport chain is significant in respiration as it generates ATP through oxidative phosphorylation.

The fossil record is significant because it provides a chronological order of species appearance, helping to trace the evolutionary history of life on Earth.

The G2 phase is crucial for preparing the cell for mitosis, ensuring all DNA is replicated and the cell is ready to divide.

The Heisenberg Uncertainty Principle states that it is impossible to simultaneously know the exact position and momentum of a particle.

The light-independent reactions, or Calvin cycle, are significant for fixing carbon dioxide into organic molecules.
