hope this helps you alot!!
Answer: White blood cells form to fight off cell infections.
Explanation:
1. Your body produces white blood cells which fight against infected cells, depends on what type of cell it is and how infected it is.
2. The immune response to a viral infection is primarily generated by a type of white blood cell called lymphocytes; cells that are mostly localized in ‘lymphoid tissues’ such as the lymph nodes or tonsils. However, the number of lymphocytes that can recognize and react against any individual type of virus is initially very small. This is particularly true for a novel virus such as SARS-CoV-2, which people have never encountered before. In order to produce an effective immune response, the small number of lymphocytes that can recognize a virus must become more abundant. Even though lymphocytes proliferate quickly it still takes several days before there are sufficient cells available to fight back against the infection. During this period the virus may also be spreading rapidly, so there is a race between the virus and the immune system that may determine the final outcome, in terms of recovery.
Note 1: Balanced forces do not cause alterization motion or movement. This is because of the fact that balanced forces are equal in size and in opposite directions. Consequently, this leads to cancellation and ultimately no movement.The net force for balancing forces is always 0.
Think of it this way: Take your right hand and left hand. Press them together; palm-to palm and five fingers to five fingers. Now apply equal amount of pressure (your force) as you push them in opposite directions (left hand left direction right hand right direction) Does any change in movement occur?
Note 2: Unbalanced forces are the forces that cause change in movement and motion. When two unbalanced forces are exerted in opposite directions, the overall force (or net force) is the difference between the two forces and the direction is in favor for the larger force.
Think of it this way. Repeat the exercise I shown you in Note 1, but this time, make apply more force in comparison to the other hand. Your right/left hand's force overpowers the weaker force of the opposite hand. The direction is in favor to your right/left hand (since they obtain the bigger force) as your hands move to the right or left side. This is an example of unbalanced forces at play.
Q22: The two forces on the left and right side are balanced given that their force is equal in size and they are in opposite directions. The two forces northwards and southwards are unbalanced forces since they are not equal in size but are opposite in direction. Recall in note 2 when I given the formula to find the net force for unbalanced forces. Its the difference (subtraction) between the bigger force and smaller force. 5 - 2 = 3. Therefore the net force for question 22 is 3.The direction is in the bigger force's direction, therefore southwards.
Q24: Is a balanced force. Therefore the net force is 0. I don't think there is technically any direction per say.
