Topoisomerase is the enzyme that can be added to correct the untwisting that is led to strain ahead of the replication fork.
Answer:
A
Explanation:
If it's a permeable membrane then it will allow certain molecules in. If it's impermeable then it won't allow molecules in. Therefore it is the deciding feature of whether something can go into the membrane.
Answer:
1. 10% 2. 90% 3. 80% 2. Yes 3. Into 3. Swell 6. Hypotonic
Explanation:
1. Given the image, it shows there is 10% glucose outside the cell.
2. Because there is 10% glucose outside the cell, you can automatically conclude that there is 90% of water outside. (You want it to equal to 100%. So, 10 + 90 = 100)
3. Given 20% glucose inside the cell based on the image, you can conclude that there is 80% water inside the cell.
2. Yes, osmosis will occur. Osmosis is the movement of water from a higher concentration to a lower concentration. In this case, there is more water <em>outside </em>the cell than in. So, yes, osmosis will occur.
3. The water will move into the cell (There's less water inside, and more outside, so of course, the water will move in).
3. The cell will swell, since water is getting moved in.
6. This is a hypotonic solution. Definition of a hypotonic solution: The concentration of solutes outside the cell is less than that of water. Hypotonic solutions always <em>swell, </em>as water moves into it.
Hopes this helps!^^ I tried the best I could at explaining.
