The external environment of a cell refers to the surroundings outside the cell, including factors like nutrient availability and temperature. The internal environment of a cell refers to the conditions within the cell, such as pH levels and concentrations of ions. Both environments are critical for the proper functioning and survival of the cell.
What else can I help you with?
What cell structure that allows cummunication between internal and external cell environment?
The cell membrane is the structure that allows communication between the internal and external cell environment. It controls the movement of molecules in and out of the cell, helping to maintain homeostasis and respond to changes in the cell's surroundings.
What is the fluid link between the external and internal environment?
The fluid link between the external and internal environment is the plasma membrane of cells. It acts as a selectively permeable barrier that regulates the passage of substances in and out of the cell, maintaining the cell's internal environment while interacting with the external environment.
What are some examples of internal and external signals that activate cell division?
Internal signals that activate cell division include growth factors and hormones such as insulin, while external signals include physical factors like cell-to-cell contact inhibition and chemical signals from neighboring cells indicating tissue repair or growth factors released by damaged tissue.
What interferes between the nervous system and the internal and external environments?
The spinal cord and brain serve as intermediaries between the nervous system and internal and external environments. They receive and process sensory information from the environment, transmit signals to the body to produce responses, and regulate bodily functions to maintain homeostasis.
What are internal cell regulators?
Internal cell regulators are proteins that respond to changes within a cell.For example, a normal cell will not enter the mitosis stage of cell division till the entire DNA is replicated. This check is regulated by a protein within the cell. This protein is the internal cell regulator.
What are the two types of external organizational environments?
The two types of external organizational environments are the internal and the external organization environments.
What are the two types of external environment?
The two types of external organizational environments are the internal and the external organization environments.
What is the internal regulatory proteins effect?
mitoconderia
Allows communication between the internal and external cell environment?
The cell membrane allows communication between the internal and external cell environment. This is due to is selective permeable nature of the membrane.
Both the internal and external environments can modify or alter a gene yes or no?
False.
What separates the internal environment of the body from the external environment?
The cell membrane separates the internal environment of the body from the external environment. It acts as a physical barrier that controls the passage of substances in and out of the cell, maintaining the cell's internal balance.
What cell allows communication between the internal and external cell?
cell(plasma) membrane
What allows communication between the internal and external cell environment?
cell(plasma) membrane
What cell structure that allows cummunication between internal and external cell environment?
The cell membrane is the structure that allows communication between the internal and external cell environment. It controls the movement of molecules in and out of the cell, helping to maintain homeostasis and respond to changes in the cell's surroundings.
What is the fluid link between the external and internal environment?
The fluid link between the external and internal environment is the plasma membrane of cells. It acts as a selectively permeable barrier that regulates the passage of substances in and out of the cell, maintaining the cell's internal environment while interacting with the external environment.
What Keeps the bodys internal environment distinct from the external environment?
The body's internal environment is distinct from the external environment due to physiological processes such as homeostasis, which regulates factors like temperature, pH, and nutrient levels. Specialized structures like cell membranes, the blood-brain barrier, and the skin also help maintain this distinction by controlling the exchange of substances between the two environments. The body's ability to selectively absorb, excrete, and regulate the concentration of substances further reinforces the boundaries between internal and external environments.
The continuous part of the plasma membrane is the?
phospholipid bilayer, which consists of two layers of phospholipid molecules. It controls the movement of substances in and out of the cell, providing a barrier that separates the internal and external environments of the cell.
