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>
Answer
1. The vascular and dermal tissues
2. Protein capsid
Explanation
Dermal tissue present in plants offer the first defense mechanism against physical damage which could be caused by insects and infections.The dermal tissue covers the outside parts of a plant except in woody shrubs and tree which are protected by the bark. Vascular tissues in plants are responsible for the transportation of water and nutrients that are vital in cell repair and growth.Through vascular tissues, the plant obtains nutrients important for the restoration of the damaged cells.
A capsid is the protein shell of a virus.It is composed of protomers which are subunits.Some viruses are enveloped by a capsid coated with a lipid membrane called the viral envelop.The main function of a capsid is to protect the genetic material of a virus while interacting with the host environment.
