Why is the earth called a closed ecosystem?
The Earth is called a closed ecosystem because it functions as a self-contained system where energy and materials are exchanged within itself without any external inputs or outputs. This means that resources are recycled within the Earth's system, making it relatively self-sustaining.
Materials enter and leave the nucleus through opening in its?
Materials enter and leave the nucleus through openings called nuclear pores. These pores regulate the movement of molecules, such as RNA and proteins, between the nucleus and the cytoplasm. They allow for communication and transportation of essential components for cellular functions.
How fats and proteins can enter the pathways of energy release?
Fats and proteins can enter the pathways of energy release through different mechanisms. Fats are broken down into fatty acids through a process called beta-oxidation, which then enter the citric acid cycle to produce energy. Proteins are broken down into amino acids, which can be converted into various intermediates that enter the citric acid cycle for energy production.
Why must materials enter and leave the cell?
Materials must enter and leave the cell in order to maintain a healthy internal environment and carry out cellular processes. Nutrients and oxygen need to enter the cell to provide energy and support growth, while waste products and byproducts of cellular activities must leave the cell to prevent toxicity and maintain homeostasis.
When does the producers energy enter the ecosystem?
The producers energy enter the ecosystem by the heat of the sun.
Do spirits require high energy points to enter the other world?

Describe methods by which substances enter and leave cells that require cellular energy?
Diffusion is the methods that leave cells. Diffusion also has to have cellular energy.
How can a liquid droplet enter a cell?
Water enters the cell through the cell membrane through a process called osmosis. It doesn't require any energy from the cell (atp) because it is a type of passive transport.
When energy is unable to pass from a system to the surrounding it is called?
When energy is unable to pass from a system to the surroundings, it is called an isolated system. In an isolated system, energy is conserved, and no energy can enter or leave the system.
Do the Materials enter and leave the nucleus through the cromatin?
Materials usually enter through the cell wall.
How does energy enter in the living world?
how does energy enter this living world
Do large proteins containing a nuclear localization signal bind to the nuclear pore and enter the nucleus without any expenditure of energy?
No, proteins with a nuclear localization signal require energy to actively transport through the nuclear pore complex into the nucleus. They are not able to enter the nucleus passively. The binding and translocation through the nuclear pore are facilitated by specific transport receptors and require energy in the form of GTP hydrolysis.
