Answer:
Biological magnification refers to a phenomenon where some of the substances like heavy metals or pesticides move up the food chain, make their way into the lakes or rivers, and are eventually consumed by aquatic species like fish. This, in turn, is further consumed by large species like large birds, humans or animals.
This is associated with the health warnings given to pregnant women as too much eating of some kind of fish may influence the immune systems, that is, may affect the health of women who are pregnant.
That would be false. The Ozone layer is what protects Earth from UV radiation. The Ozone is part of the Stratosphere.
Answer: It should be D.
Explanation
Facilitated- requires energy- large molecules require energy to go cross the phospholipid bilayer.
Answer:
pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. Water that has more free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic. Since pH can be affected by chemicals in the water, pH is an important indicator of water that is changing chemically.
Answer:
Variables that cannot be associated with its population dynamics, in this case, for example, different streams with the same characteristics (for example, orientation, force direction, etc).
Explanation:
In this experiment, examples of dependent variables may include the growth rate, the survival rate, and the birth values of freshwater mussels.
The dependent variables are those you have to measure exactly in the experiment. In this case, dependent variables are represented by population values of freshwater mussels under different stream conditions.
