Following the Free-body Diagram, these are the Four types of Resistance Force with descriptions:
1. Applied Force - if a person is pushing the table across the hall, then an applied force is acting on the table.
2. Frictional Force - if a book slides across the surface of the table, then the table exerts a frictional force in the opposite direction of its motion.
3. Normal Force - if a stone is resisting upon the floor, then the floor is exerting an upward force upon the stone in order to support the weight of the stone.
<span>4. Gravitational Force- all things on Earth experience gravity or the downward force towards the center of the Earth. It makes all object that are thrown upward will make the objects to fall down.</span>
Answer:
Cell cycle regulators
Explanation:
Cell division is important for an organism for growth, repair and replacement of cells and tissues. In the unfortunate event of uncontrolled cell division, the organism makes more cells than it can produce. Growing cells have four phases
G1: Growth by doubling of cytoplasm and organelles
S: Synthesis of new DNA and doubling of chromosome number
G2: A second round of growth to prepare for cell division
M: Cytokineses and the formation of two very identical cells
In an attempt to end the uncontrolled cell division one would first look into factors that initiate the G1 phase; stopping the growth of an out of control cell before it starts.
A second approach is to look into manipulating the check points at G2 and M. If there are drugs that can interfere at this point the cell will not divide uncontrollably and the potential cancer will be interrupted.
