Answer:
It is important to have more than one piece of evidence to make sure that the evidence is actually evidence. Or in other words, that the evidence is proven true. With only one piece of evidence, you can't be fully sure if calculations were correct, if the source was trustworthy, etc.
Multiple evidence is kinda like double checking math problems. If you don't do it, you can't be 100% certain the answer is correct.
Blood is isotonic to cells in order to conserve the shape and structure of the surrounding cells.
- Isotonic solutions are solutions that have the same concentration of water on both sides of a cell membrane.
- In this case, the blood is an aqueous fluid that exhibits isotonic properties compared to its surrounding cells.
- Isotonicity enables the blood to transport oxygen and nutrients to the cells but simultaneously conserves the structure and form of these cells.
In conclusion, blood is isotonic to cells in order to conserve the shape and structure of the surrounding cells.

Answer:
v = 5 m/s
Explanation:
Given that,
The distance covered by a runner, d = 400 m
Time, t = 80 sec
We need to find the runner's average speed. It is equal to total distance covered divided by time taken. It can be given by:
So, the runner’s average speed is 5 m/s.
The second one because there is no solute outside for the water to move towards. It will go inside and it may explode
