DDT has adverse affect on our environment due to its presence for a long time.

<h3>What is DDT?</h3>

DDT is an insecticide that can pass up in the food chain i.e. from insects to small birds, and then from small birds to big birds like hawks. High concentrations of DDT in birds leads to weakness in the egg shells.

This leads to a decrease in their population so we can conclude that DDT has adverse affect on our environment due to its presence for a long time.

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.
