Answer:
Cost: competition for mates, competition for resources
Benefit: better protection from predators (ex. a fish in a school of fish has greater chances of not getting eaten because of the large number of other fish)
Tissues are below complex organs.
<h3>What are the tissues?</h3>
- The body is made up of four different types of tissue: epithelial, connective, muscular, and nervous. Each has a purpose for which it was created.
- Connective tissue, epithelial tissue, muscular tissue, and nerve tissue are the four fundamental forms of tissue. Other tissues are held together and supported by connective tissue (bone, blood, and lymph tissues). A coating is provided by epithelial tissue (skin, the linings of the various passages inside the body).
- Tissue that gives bones their strength and structure. Compact tissue (the tough outer layer) and cancellous tissue make up bone (the spongy, inner layer that contains red marrow). Osteoblasts, which build new bone, and osteoclasts, which break down existing bone, maintain bone tissue.
- Blood tissues can be found inside blood vessels, including arteries, arterioles, capillaries, venules, and veins (for more information on the names of individual blood vessels and the course the blood takes, see systemic circulation), as well as inside the heart's chambers.
To find the level is just below organs in complexity:

Answer:
In hypertonic solutions, the cells will shrink and in hypotonic solutions the cells will fill up
Cells with cell walls will be able to control their tonicity better than cells without cell walls.
Explanation:
Cells with cell walls
- In a hypertonic solution (high solute concentration), water will flow out of the cell into the solution until equilibrium is reached. If the solution has a high concentration of solute the cell may undergo<u> plasmolysis where the plasma membrane detaches from the cell wall.</u>
- In a hypotonic solution: Water will flow into the cell because it has a higher solute concentration compared to the solution. This will continue until the cell is <u>turgid</u>. If more water continues to enter the cell, the cell is at risk of bursting, this takes a while because the cell wall will withstand the pressure.
Cells without cell walls
- In a hypertonic solution: Water will diffuse out of the cell, however there is no cell wall so cell is in danger of shrinking and dying.
- In hypotonic solution: Water will diffuse into cell,the cell will become turgid and if water keeps moving in the cell will burst because it has no cell wall to resist the pressure.
