Distance travelled by Bob was 7 meters and the displacement was 5meters.
<h3><u>Explanation:</u></h3>
Distance is defined as the total length of the path travelled by a body from its initial position to final position. Displacement on the other hand is defined as the length of the straight line joining the initial position and the final position of the body.
Here, Bob travelled from point A to point C via point B which took him to travel more distance. The length of distance from point A to B is 4 meters and from point B to C is 3 meters. So the total distance covered is 
meters = 7 meters.
While the length of path straight from point A to C is 5 meters. So displacement is 5 meters.
Answer:
Wilting of leaves occur.
Explanation:
if the leaf tissue is kept at high temperature during the process of cell isolation the leaf will shrink because of loss of all water. Due to high, temperature the stomata will be open and water is removed in order to remove heat from the body. A time comes that all water that is present in the cell will be removed and as a result wilting of leaves occur.

The question is incomplete as it does not have the options which are-
1. narcotic analgesics
2. non-narcotic analgesics
3. anti-psychotic barbiturates
Answer:
Non-narcotic analgesics
Explanation:
Non-narcotic analgesics are the drugs used medication to treat and control the inflammation and pain. They are used to treat mild to moderate pain usually but with other medications to treat severe pain like Advil, Tylenol and other.
The drug act by preventing the perception of the pain stimulus by blocking the transmission of the impulses generated in response to pain to the central nervous system.
Thus, Non-narcotic analgesics is the correct answer.
