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.

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

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.

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.

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

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

Lipids primarily serve as energy storage molecules.

Nervous tissue is responsible for the transmission of electrical impulses throughout the body, facilitating communication.

Parathyroid hormone (PTH) increases calcium levels in the blood by stimulating the release of calcium from bones and increasing calcium absorption in the intestines.

Petals are often brightly colored to attract pollinators.

Potassium plays a crucial role in regulating water balance and osmotic pressure in plant cells.

Producers, such as plants, produce energy through photosynthesis, forming the base of the food chain.

Proteins act as enzymes that catalyze biochemical reactions.

Proteins primarily function as enzymes that catalyze biochemical reactions.

Ribosomes are responsible for protein synthesis in the cell.

The Achilles tendon connects the calf muscles to the heel bone, allowing for foot movement.

The cell wall provides protection and support to the cell, maintaining its shape and preventing excessive water uptake.

The primary function of the contraceptive pill is to prevent ovulation, thereby reducing the chances of pregnancy.

Petals are primarily designed to attract pollinators with their color and fragrance.

The Golgi apparatus modifies, sorts, and packages proteins for secretion or delivery to other organelles.

Cortisol is a steroid hormone that helps control the body's stress response and regulates metabolism, immune response, and blood sugar levels.

The primary function of the immune system is to protect the body against diseases and infections.

The lymphatic system is responsible for transporting lymph, a fluid that contains infection-fighting white blood cells, and plays a crucial role in the immune system.

The primary function of the male reproductive system is the production of sperm, which is essential for fertilization.

The myelin sheath acts as an insulator and increases the speed of nerve impulse transmission through saltatory conduction.

Phloem is responsible for the transport of food (sugars) produced during photosynthesis from leaves to other parts of the plant.
