cell works as an open system i.e it takes in substances needed for metabolic activity through its cell membrane.Then it performs its metabolic processes assigned to it .Product and by-product are form in metabolism.Cell either utilizes the product or transport them to other cells.The by-product either stored out of the cell.
When the nervous system signals a muscle to contract, calcium channels open in the muscle cell membrane. Calcium ions then flow into the muscle cell, triggering a series of biochemical events that eventually lead to muscle contraction.
I think it goes Cell,Tissue , Organ, and then Organ System
It is possible to remotely unlock a car door using a cell phone, but it requires a specialized app or device that is compatible with the car's remote unlocking system. This technology allows users to unlock their car doors from a distance using their cell phone.
The first law of thermodynamics states that: "The internal energy of a system is a function of its state. Any increase in the internal energy of a system is equal to the sum of the heat supplied to the system and the work done on the system." In equations, this is stated as: DU = DQ + DW where DU is the INCREASE in internal energy DQ is the heat SUPPLIED DW is the work done ON the system So, if heat is lost by the system, it means that DQ is negative and if work is done by the system, it means that DW is negative. The best way to answer thermodynamics questions involving the first law is to think logically about what calculations should be made. If you do this, you will never make mistakes about signs.
The organelles that are a part of the endomembrane system include the endoplasmic reticulum, Golgi apparatus, lysosomes, vesicles, and the nuclear envelope. The endomembrane system is a network of membranous organelles within a eukaryotic cell that work together to transport proteins, lipids, and other molecules throughout the cell and to the cell membrane. It plays a key role in protein synthesis, processing, and trafficking within the cell.
A cell is considered an open system because it exchanges energy and materials with its surroundings. This allows the cell to maintain its internal environment despite fluctuations in the external environment.
An open system is a system that allows a great deal of flexibility. Similar to open source software, it allows users to improve the work as time goes by.
A fuel cell is different from a battery cell in so far as reactants are constantly supplied to a fuel cell making it an open system whereas a battery cell is a closed system that stores the reactants within it. A fuel cell works as long as fuel is supplied to it whereas a battery cell requires regular replacements.

the ciculatory system is where blood in our body is transported around the body giving our cell the oxygen they need.
Voltage-gated sodium channels open in response to changes in electrical charge, allowing sodium ions to flow into the cell. This influx of sodium ions creates an electrical signal that travels along the nerve cell, facilitating the transmission of signals in the nervous system.
Wiki will not do your homework for you, so it is time you open your science book and start to read. The answer is there in the book. Get to work.
Energy in an open system can be exchanged with its surroundings, either in the form of heat or work. The total energy of an open system remains constant, but the amount of energy within the system can change as energy is exchanged with the surroundings.
Some sort of system has to carry the nutrients to each cell and carry away their wastes. This job is given to the circulatory system.
