HURRY!! PLEASE HURRY!
diamong [38]

Explanation:

cost

  • ongoing maintenance
  • initial design and construction​

benefit

  • protection of infrastructure
  • lower insurance costs
  • employment opportunities

The flood mitigation projects have initial startup costs and ongoing maintenance costs over the years. However, apart from the costs, these have additional benefits like lower insurance costs due to protected infrastructure and  reduced flood damage, along with employment opportunities during building and maintenance.

Further Explanation:

Flooding usually happens when lots of rainfall occurs in relatively short time periods. These are usually enough to cause rivers to overflow their banks and also occur when storms force large volumes of water from the ocean to travel inland.  Typically these occur in arid ecosystems, having low average rainfall- the water accumulates in dry regions and saturates the area. This phenomena are majorly destructive and can uproot trees, destroy bridges, buildings and other infrastructure while leading to loss of life.

marissa [1.9K]

Based on the Tonicity in Elodea Cells lab, a hypotonic environment causes a cell to swell or burst because
asambeis [7]

Answer:

The correct answer is -

the water in the solution moves into the plant cell

the solutes in the solution have a lower concentration than the solute concentration inside the plant cell

the water is moving down its concentration gradient from high to low.

Explanation:

The hypotonic solution consists low concentration of solutes and a higher concentration of water as compared to the concentration of solutes and water of other solutions or cells. Water tends to move from a higher concentration of water to a lower concentration of water therefore the cell swell and then ultimately burst.

Water movement in such conditions is known as the movement down the concentration gradient as it moves from its higher concentration to a region of its lower concentration.
