You will use dialysis tubing to mimic and artificial cell to see if it acts as selectively permeable barrier. How will you determine if water has moved across the wall of your
dialysis tubing from the beaker into the tube?
O by looking for a decrease in the volume of water in the beaker
Othere is no way to determine if water has entered the bag
O by measuring the reduced concentration of starch in the bag
O by weighing the bag before the start and at the end the experiment

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.

correct answer: false

while planning water activities, it is very important to consider the weather, because if we do not plan and are going for a surf, then it might be that the hurricane came and drown us or may carry us to long distance from where we can not come back. there are many reasons to take information about the weather when we are planning any water activities.

hence, the correct answer would be false.

a compound light microscope is used to magnify objects in steps.
