What will be the economic and social consequences of this loss of biodiversity? Can anyone help please?
Daniel [21]

Answer:

economic consequences

Whilst human-made changes to ecosystems have often generated large economic gains, biodiversity loss damages the functioning of ecosystems and leads to a decline in essential services, which may have severe economic consequences, particularly in the longer term.

social consequences

Biodiversity loss can have significant direct human health impacts if ecosystem services are no longer adequate to meet social needs. Indirectly, changes in ecosystem services affect livelihoods, local migration and, on occasion, may even cause or exacerbate political conflict

If a cell is placed in an isotonic medium, there will be no net movement of water. True or false?.
ASHA 777 [7]

It is true.

<h3>What is isotonic medium?</h3>
  • A solution that has the same amount of salt as cells and blood. In hospitalized patients, isotonic solutions are routinely utilized as intravenous fluids.
  • When a cell is immersed in an isotonic solution, there is no net movement of water into or out of the cell, and the volume of the cell remains constant.
  • Isotonic solutions include 0.9% normal saline and lactated ringers. A hypertonic solution is one that has a greater solute concentration than the solution across the semi-permeable barrier.
  • The isotonic solution allows the cells to move water and nutrients in and out of the cells. This is necessary for the blood cells to perform their function of supplying oxygen and other nutrients to other parts of the body.
