A meter ruler or a tape measure

You would use the SI unit meter (m) to measure the length of a DVD case.
Length is a physical quantity that measures the extent of something along a straight line. Common units used to measure length include meters, centimeters, inches, and feet. Length is commonly used to describe the size and distance of objects.
A micrometer or caliper would typically be used to measure the dimensions of a pin, such as its diameter or length, with precision.
You would use the SI unit of length, which is the meter (m), to measure a paper clip.
The water level increases in the capillary tube due to osmosis because the concentrated sugar solution in the dialysis tubing creates a lower concentration of water molecules inside the tubing. This lower concentration of water inside the dialysis tubing creates a concentration gradient that drives water to move from the beaker outside the tubing into the tubing through osmosis, causing the water level in the capillary tube to rise.
In the dialysis tubing bag experiment, if glucose and I2KI are present inside the bag, the color of the I2KI solution will turn blue-black due to the reaction of iodine with starch present in the glucose solution. This color change indicates the presence of glucose inside the bag.
The cup will remain orange if you put iki in it, and the tube will turn darkish blue or you can call it black.
Osmosis is usually detected by simply looking at the experiment - most of the time, enough water is transferred to cause a noticeable rise/fall in water levels. However, I assume you could tell through the usage of weighing scales - as water re-distributes, as would the weight.
Insects, screws and nails, tubing are some examples.
I would measure it with a ruler.
centimeter
Any measure of length will do, but the most common would be feet or meters.
You would answer it with cubic feet
length
A metres, for an approximate measure, a centimetre for a more accurate measure.
I would use feet
