Osmosis is the net movement of water molecules through a semi-permeable memberane from a region of higher water potential to a region of lower water potential.
so in the first case, since 10% of sucrose solution has a lower water potential than the pure water, so water molecules will flow into the sac, causing the sac to increase in volume. note that sucrose molecules can't diffuse out since there's a semi-permeable membrane.
in the question, I'm not 100% sure what the "sac solution" is meant by, but I guess it's the solution inside the sac
so here if the sac sucrose is 20%, the concentration of water is larger in difference than the first time, so osmosis rate will increase.
but if the "sac solution" is meant by replacing the water of the first case, then the sac inside would have a higher water potential, as the sucrose concentration is more diluted. then the water molecules will flow from the sac back to the beaker or whatever container it is.
Answer:
Bottom-up processing
Explanation:
The information collected from the environment are used to determine how we interact with our environment. The process and manner that the information derived from our sensory organs are put together, analyzed and understood, and the experience felt consciously is knowns as perception
The order of the process of perception can be such that the perception is comes from and is based on the direct stimuli on our senses which is known as bottom-up processing. Whereby the the observed sensation are rather analyzed and interpreted based on previous knowledge or thought process, the order is referred to as top-down processing.
The answer is B because I got it
Answer:
6000,
Explanation:
if it was 6500 or more it would be 7000, so its 6000
I would say it’s emotional support because he is helping him or supporting him when he needs help with his emotions
