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.

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.

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

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

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.

Lipids primarily serve as energy storage molecules.

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

Nucleic acids, such as DNA and RNA, are primarily responsible for storing and transmitting genetic information.

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.

The primary function of petals is to attract pollinators with their color and fragrance.

Plasma is the liquid component of blood that carries nutrients, hormones, and waste products throughout the body.

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.

Ribosomes are responsible for protein synthesis in the cell.

Surfactant reduces surface tension in the alveoli, preventing their collapse and making it easier for the lungs to expand during inhalation.

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

The primary function of the alveoli is gas exchange, where oxygen is absorbed into the blood and carbon dioxide is released.

The anther is the part of the stamen that produces and contains pollen grains.

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