The delay that exists in drag race drivers shows the human reaction time which is being compared with the anticipated green light.
In drag raising, we have break-out where a car runs quicker the dial-in while delay box is an electric device which is an aid to the driver.
The driver adjusts his reactions by changing his number in the delay box whereby he sets brake on just one set by line-lock.
Reaction time indicates the amount of delay from the last yellow light which is being turned on. 500 indicates that green light it is the perfect light and if delayed below 500 it shows that the car started moving before the green light.
The coastline experiences tidal bulge twice a day. :3 Good luck!
It serves as energy for the body the cells it helps carry out nerve ceel conduction muscle cell contraction, active transport and the production of chemical substances.
Answer:
Macrophages are part of your innate immune system, which is antigen-independent and does not require activation.
Explanation:
Macrophages phagocytize (internalize) all non-self pathogens it encounters. These do their job without activation. Other cells in the innate immune system include basophils, neutrophils, eosinophils (these cells are polymorphonuclear leukocytes), mast cells, and dendritic cells, which act as the bridge between your innate and adaptive immune system.
All of the other entities listed above are part of your adaptive immune system. The adaptive immune system is antigen-dependent and requires activation. This section of your immune system responds differently to different pathogens, and has the bonus of having immunologic memory, the ability to remember pathogens after infection and respond much quicker upon secondary and tertiary encounters.
Note: All lymphocyte types begin as naïve cells, which then differentiate into their fully matured form upon activation.
Helper T cells are a type of CD4+ T cell that has the job of activating B and T lymphocytes. There are two different types of T helper cells: Th1 and Th2. Th1 cells secrete the cytokine interferon-gamma (IFNγ), and is primarily involved with the stimulation and activation of cytotoxic T cells, while Th2 cells secrete a variety of cytokines and are responsible for activating and assisting with B cells to make antibodies. To make a long story short, Th cells interact with APC (Antigen Presenting Cells), specifically their Class II MHC (a group of genes that present exogenous proteins). The Th cells then proliferate and gain the ability to activate these APC cells and provide the necessary signals to activate B and T cells and make them proliferate and do their specific function.
