A selectively permeable membrane separates solution a and
Yakvenalex [24]
The water molecules will flow from b to a due to osmosis.

Osmosis is where water molecules will flow from a region of higher water potential to a region of lower water potential, through a selectively permeable membrane.

When the water molecule concentration is higher, it has a higher water potential top. Water potential is the tendency for them to flow to a lower region.

The net movement will stop until both sides of the solution has a same water potential.

Write a brief account of Ernest Rutherford’s personal and professional life in no more then 150 words
Alborosie
<span><span> i think the answer is that >>>>>Ernest Rutherford was born in rural Spring Grove, on the South Island of New Zealand on August 30, 1871. He was the fourth of 12 children, and the second son. His father, James, had little education and struggled to support the large family on a flax-miller’s income. Ernest’s mother, Martha, worked as a schoolteacher. She believed that knowledge was power, and placed a strong emphasis on her children’s education.As a child, Ernest, whose family called him “Ern,” spent most of his time after school milking cows and helping with other chores on the family farm. Weekends were spent swimming in the creek with his brothers. Since money was tight, Rutherford found inventive ways of overcoming his family’s financial challenges, including birds-nesting to earn funds for his kite-flying supplies. “We haven’t the money, so we’ve got to think,” was Rutherford’s motto at the time.<span><span /></span>
