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>
Mid ocean ridges occur where two tectonic plates diverge or move away from each other. This separation occurs under the ocean.The Mid-Atlantic Ridge is such an example and is where the North and South American plates pull away from the Eurasian and African plates. Mid ocean ridges are usually a combination of divergent and transform plate boundaries. At transform boundaries plates slide past each other in opposite directions.
The right answer for the question that is being asked and shown above is that: "selective cutting" This type of harvesting leaves behind a diverse forest. The type of harvesting is called the <span>selective cutting.</span>
