Answer:
A.Both of you pull with equal force on opposite sides of the ball.
Explanation:
Balanced forces means that the total force or the sum of the force done on the object should be equal to 0 newtons or in other words, it should not be moving.
Force is defined as the push or pull on an object. For both people to balance out the forces on the ball while both applying a force, you need to do this from opposite sides.
You could either pull with equal forces on opposite sides of the ball or you can push with equal forces on opposite sides of the ball.
→ ball ←
← ball →
For the other choices, if you both push or pull on the same side, the ball would move that direction because there is no opposing force.
ball → →
If one pushes while the other pulls on opposite sides, it will move the direction you are pulling and pushing.
→ ball →
Answer:
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. The replication process relies on the fact that each strand of DNA can serve as a template for duplication. DNA replication initiates at specific points, called origins, where the DNA double helix is unwound. A short segment of RNA, called a primer, is then synthesized and acts as a starting point for new DNA synthesis. An enzyme called DNA polymerase next begins replicating the DNA by matching bases to the original strand. Once synthesis is complete, the RNA primers are replaced with DNA, and any gaps between newly synthesized DNA segments are sealed together with enzymes. Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.

Septic shock occurs when bacterial toxins trigger vasodilation and increase capillary permeability.
Vasodilation occurs during inflammatory processes thereby leading to an increase in blood flow. Septic shock cause the release of numerous vasodilatory chemicals thereby leading to lethal hypotension.
Septic shock is caused by changes in hemodynamic profile as a result of endothelial dysfunction with increased capillary permeability thereby leading to hypotension.
