Because DNA is shaped in the form two helix combined thus creating a double helix. RNA is not shaped this way, instead it is shaped as a sort of twisted half ladder compared to DNA’s twisted full ladder shape
1. The correct answer is; are body cells is going to shrink. <span>Salty seawater is a hyperosmotic solution, meaning that it has more solutes than the cell inside. The water will move (from the cell) via osmosis in order for the solutions to reach equilibrium. Also, salty solution exerts more pressure on the of the cell, so the cell will shrink.</span>

2. The correct answer cells in the fish will stay the same size. This will occur because both solutions, freshwater lake and river have similar (or equal) solute concentrations. Those solutions are called isosmotic. There is no movement of water or the solutes, so the cell stays the same.</span>
3. The correct answer is to swell. <span>This will happen because sea star egg has the same solute concentration as its first environment-ocean meaning that this solution is hyperosmotic comparing to the lake (ocean is saltier than the lake, it has more solutes). When you put the sea star egg in the lake, the water from the lake will move (via osmosis) into the egg, to reach equilibrium. Water will cause the cell to swell.</span>
the answer would be C by thr ionic bonding
Answer:
The main difference between living and non-living things is that a living organism is or was once alive, whereas a non-living thing has never been alive. Non-living is not the same as being dead because non-living things were never alive and therefore cannot die.
