By dating the rocks in the ever-changing crust, as well as neighbors such as the moon and visiting meteorites, scientists have calculated that Earth is 4.54 billion years old, with an error range of 50 million years.
Answer:
Cell wall: A protective layer covering the outside of the cell. They keep the shape of the plant cell, prevent water loss, and provide support.
golgi apparatus: Transports proteins and lipids around the cell. Often it is called the shipping department of the cell.
chloroplast: Chloroplasts store chlorophyll and this is where photosynthesis takes place in the cell.
Cell membrane: A layer that covers the cell, acts as a gate and determines what comes and goes through the cell. It allows good things in, while keeping others out.
Intermediate filaments: Provides support when when the plant cell comes into contact with other cells.
Ribosome: The part of the cell that is responsible for creating proteins.

Answer:
Invasive species compete for the same natural resources such as food and water which the native species also need for survival.
Explanation:
Invasive species upset the stability of the ecosystem because the prey in their new environment does not have the needed defense against them. They also upset the food chain, consume so much, and overpopulate in the new territory thus causing the extinction of the native species.
The introduction of brown tree snakes in Guam disrupted the ecological system as their population increased rapidly because their preys in this new environment lacked the ability to defend themselves against the brown tree snakes. For this reason, more than twelve native birds in the Guam Islands went into extinction. They also consumed the natural resources needed for the survival of the native species.
