Carbon is released into the atmosphere only during the burning of fossil fuels
Explanation:
During the process of fuel burning, carbon is released in the atmosphere. The human invented power plants, factories, cars and other vehicles releases carbon in the form of carbon di-oxide in atmosphere.
However, the cellular respiration is similar to that of fuel burning as it is too a combustion process. But the carbon produced in this process fuels the inner cellular activities rather than releasing it in the atmosphere.
The discharge in the stream at a given cross-section and the level of the stream is described by a rating curve<span>. Average velocities and the cross-sectional area of the stream are measured for a given stream level. The velocity and the area give the discharge for that level. After measurements are made for several different levels, a </span>rating table<span> or rating curve may be developed. Once rated, the discharge in the stream may be determined by measuring the level, and determining the corresponding discharge from the rating curve. If a continuous level-recording device is located at a rated cross-section, the stream's discharge may be continuously determined.</span>
When that situation happens then it can stimulate a cytotoxic T cell. This types of cells are the ones directly responsible for cellular immunity. Cytotoxic T cells can attack target cells by secreting a cytokine that triggers apoptosis which is <span>the death of cells which occurs as a normal and controlled part of an organism's growth or development.</span>
Carbohydrates are mainly transported in the phloem in the form of sucrose. The cell membrane of the sieve cells contains pump proteins that actively convey sucrose into the vascular pathways.
