Answer:
Look down
Explanation:
Firstly, since they were so different, and that fed into American's fear of the unkown. It also made Americans nervous because they felt outnumbered by these foreigners, and they felt like immigrants were going to take "their america."
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.
Hey is there a way you could insert the application . Maybe ctrl c then ctrl +v . or snap shot even thanks!
Answer: c) Researchers think that stresses created by humans are the reason behind increasing numbers of elephant attacks.
Explanation:
The aforementioned article by National Geographic shows that the higher number of elephant attacks on humans are as a result of human activities that are placing stress on elephants.
Humans are increasing in population and as a result need more land for farming. This is resulting in a shrinking habitat for elephants who then encroach on human farms and are killed for it which leads to some elephants having Post Traumatic Stress Disorder and killing other humans which then continues the cycle.
Since we are given that
the mean is 15.2 oz
standard deviation of 0.5 oz
and simple random sample of 7
then we have an
<span>Exact normal distribution with mu equal to 15.2 and sigma equal to 0.4
since the samples are simple and random</span>
