Which type of symbiotic relationship benefits both organisms involved?
Answer: Mutualism
Mutualism is a symbiotic relationship in which both organisms benefit. An example is the relationship between bees and flowers, where bees get nectar and flowers get pollinated.
What is the correct order of the levels of biological organization from smallest to largest?
Answer: Cell, tissue, organ, organ system, organism
The hierarchy of biological organization goes from cell (smallest) to tissue, then organ, organ system, and finally the complete organism (largest).
Which biome is characterized by permafrost and extremely cold temperatures?
Answer: Tundra
The tundra biome is characterized by permafrost (permanently frozen soil), extremely cold temperatures, low precipitation, and minimal vegetation such as mosses, lichens, and small shrubs.
What is the primary function of red blood cells?
Answer: Transport oxygen
Red blood cells (erythrocytes) contain hemoglobin, which binds to oxygen in the lungs and carries it to tissues throughout the body. They also help transport carbon dioxide back to the lungs.
In a food chain, what are organisms that produce their own food called?
Answer: Producers
Producers (autotrophs) are organisms that can make their own food, usually through photosynthesis. They form the base of food chains and include plants, algae, and some bacteria.
Which of the following is NOT a function of the skeletal system?
Answer: Producing hormones for digestion
The skeletal system provides support, protects organs, allows movement, stores minerals, and produces blood cells in bone marrow. Producing hormones for digestion is a function of the endocrine and digestive systems.
