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>
I believe, for the artery, they have, an open, circular lumen an a thick media
Veins on the other hand, have somewhat collapsed lumen and a thinner media. Arteries are blood vessels that carry blood out of the heart to other parts of the body, all arteries carry oxygenated blood except the pulmonary artery which carries deoxygenated blood from the heart to the lungs. Veins carry blood from other body parts to the heart, all veins carry deoxygenated blood except the pulmonary vein which caries oxygenated blood from the lungs to the heart.
Imagine that a person has a disorder of the pancreas that does not allow it to secrete digestive enzymes. The breakdown of the macromolecule would be <span>affected the most by this disorder. The macromolecule is called the "Nucleic Acids."</span>
Answer:
The answer is Haploid. Human reproductive cells contain a single set of chromosomes and are known as haploid.
Hope that helped! :)
