Answer:
Results from method B is more reliable than method A.
Explanation:
The two method that are used for the analysis produced different results. The first method that is method A gives higher value of the iodine content than the method B.
When 
was added to water, method A showed an increased in the iodine content and it increases with the increase in the amount of .
Where as in the method B, there is no change in the results. Therefore the measurements provided by the method A shows an inference of ion.
The measurement of the iodine content is affected by the presence of the ion in water.
Since in method B there is no change in measurement, it is independent of the presence ion in water.
As higher iodine content is given by method A, so ion must be present in original water that must be interfering the measurement. Hence, method B is more reliable.
Answer:
Lysosomes are predominantly found in eukaryotic animal cells and are responsible for breaking down cellular debris
Explanation:
Answer:
The pressure in the gas is 656mmHg
Explanation:
In calculating the pressure of the gas;
step 1: convert the height of the mercury arm to mmHg
9.60cm = 96.0 mmHg
step 2: convert 752 torr to mmHg
I torr is 1 mmHg
752 torr = 752mmHg
Step 3: since the level of mercury in the container is higher than the level of mercury exposed to the atmosphere, we substrate the values to obtain our pressure.
So, 752mmHg - 96mmHg = 656mmHg
The pressure in the gas container is therefore 656mmHg.
N. B : if the mercury arm is in lower position, you add.
Plants don't need sap. They make it like Maple trees.
