Creatine phosphate provides a rapid source of energy for muscle contraction during short bursts of activity.

ATP (adenosine triphosphate) is the primary energy source for muscle contraction.

Urea is the primary excretory product formed from the breakdown of proteins in the liver and is excreted by the kidneys.

Urea is the primary nitrogenous waste product excreted by humans, formed in the liver from ammonia and carbon dioxide.

All of the above factors affect the rate of a chemical reaction.

Water availability is crucial for photosynthesis, as it is a raw material needed for the process.

Climate is the primary factor influencing the distribution of organisms, as it affects temperature, precipitation, and seasonal changes.

The inductance of a coil is determined by the length of the wire, the number of turns, and the material of the core.

Climate is the primary factor that determines the type of ecosystem in a particular area, influencing temperature and precipitation.

Ex-situ conservation focuses on the captive breeding of endangered species outside their natural habitats.

The primary focus of the Convention on Biological Diversity (CBD) is sustainable development and the conservation of biological diversity.

Covalent network solids are held together by covalent bonds, forming a continuous network throughout the solid.

Metallic solids are held together by metallic bonds, which involve a 'sea' of delocalized electrons around positively charged metal ions.

Metallic solids are held together by metallic bonds, which involve a 'sea of electrons' that are free to move.

A diode primarily functions to rectify current, allowing it to flow in one direction only.

Antibiotics are primarily used to treat bacterial infections by inhibiting the growth of bacteria.

Antioxidants prevent oxidation, which can lead to spoilage and degradation of food quality.

Antioxidants prevent oxidation by neutralizing free radicals, thus protecting cells from damage.

Antioxidants prevent oxidation, which can lead to cellular damage and contribute to various diseases.

Auxins primarily stimulate root growth and are involved in various growth processes.

The primary function of blood as a connective tissue is transport.

Cholesterol is essential for the production of hormones, including steroid hormones and vitamin D.

Ciliated epithelial cells are specialized for the movement of substances across their surface, such as mucus in the respiratory tract.

Cytokinins primarily stimulate cell division and are involved in various growth processes.

Decomposers break down dead organic matter, recycling nutrients back into the ecosystem.

Glucagon is a hormone that raises blood glucose levels by promoting the conversion of glycogen to glucose in the liver.

Hemoglobin is a protein in red blood cells that binds to oxygen in the lungs and carries it to tissues throughout the body.

Hemoglobin's primary function is to carry oxygen from the lungs to the tissues and return carbon dioxide from the tissues to the lungs.

Leaves are primarily responsible for photosynthesis, converting sunlight into energy for the plant.

Ligaments connect bone to bone, providing stability to joints.
