T cells require signaling through the T cell receptor (TCR) upon recognition of a specific antigen presented by antigen-presenting cells, as well as co-stimulatory signals from molecules like CD28 on the T cell and CD80/86 on the antigen-presenting cell. These signals are necessary for T cell activation and proliferation.

What factors determines whether a cell will divide?
Factors that determine whether a cell will divide include signals from the cell's environment, internal genetic and epigenetic factors, availability of nutrients and energy, and the cell's own regulatory mechanisms such as checkpoints that monitor DNA integrity and cell size. If the conditions are favorable and the cell receives appropriate signals, it will enter the cell cycle and divide.
What determines whether a 'cell' will divide?
Cell division is primarily regulated by internal signals, such as the cell cycle checkpoints that monitor cell progression, as well as external signals from the body's environment that influence cell growth and division. Key factors that determine whether a cell will divide include the presence of growth factors, DNA damage, and proper alignment of cellular structures. Ultimately, a balance between promoting factors like growth signals and inhibitory factors like DNA damage checkpoints governs cell division.
What grows faster than a cell forcing it to divide?
Factors such as hormonal signals, growth factors, or DNA damage can trigger a cell to divide faster than normal. Abnormal cell growth or mutations can also lead to uncontrolled cell division, as seen in cancer cells.
In the cell cycle external regulators direct cells to?
In the cell cycle, external regulators direct cells to either continue dividing or stop dividing based on signals from the environment. These signals help ensure that cells only divide when needed and in the proper conditions.
What give the signal for a cell to divide in the Cell Cycle?
Various signals, such as growth factors, nutrient availability, and DNA damage, can trigger a cell to divide in the Cell Cycle. These signals activate specific checkpoints and regulatory proteins within the cell to ensure that conditions are favorable for cell division to proceed.

Why do you think Only solar cell and not dry cells or automobile batteries are used in satellites?
the others require a medium in order to transmit and recieve the signals from outer space

When cells fail to respond to the signals that regulate the cell cycle of most cells they form?
When cells fail to respond to cell cycle regulation signals, they can form tumors due to uncontrolled cell division. This can lead to the development of cancer as the cells continue to divide uncontrollably.
What grows faster than a cell forcing it to divide?
Factors such as hormonal signals, growth factors, or DNA damage can trigger a cell to divide faster than normal. Abnormal cell growth or mutations can also lead to uncontrolled cell division, as seen in cancer cells.
What controls the rate at which cells divide?
The rate at which cells divide is controlled by various factors, including signals from the environment, the presence of growth factors, and internal regulators such as cyclin-dependent kinases. These factors coordinate and regulate the cell cycle to ensure proper cell division.
In the cell cycle external regulators direct cells to?
In the cell cycle, external regulators direct cells to either continue dividing or stop dividing based on signals from the environment. These signals help ensure that cells only divide when needed and in the proper conditions.
What does GPS stand for in a GPS car locator?
GPS is an abbreviation for "Global Positioning System". This is a system that uses satellite signals in order to find your current position on the globe. It does not require cell phone signal, though it can be a feature on a cell phone. It is becoming more widely used in vehicles, cell phones, and other devices.
What part of the nerve cell carries signals toward the part of the cell that houses the nucleus?
The dendrites of the nerve cell carry signals toward the cell body where the nucleus is located. Dendrites receive signals from other nerve cells or sensory receptors and transmit these signals to the cell body for processing.
Why do cell need to divide and produce new cells?
In order to replace the cells that are dieing
What give the signal for a cell to divide in the Cell Cycle?
Various signals, such as growth factors, nutrient availability, and DNA damage, can trigger a cell to divide in the Cell Cycle. These signals activate specific checkpoints and regulatory proteins within the cell to ensure that conditions are favorable for cell division to proceed.
What are three different ways a cell can respond to a cell?
Sending signals Recening signals Responding to a signal
