Answer:
the gar population will increase, the diving duck will decrease slightly and the crab population will decrease
Explanation:
Since the alligator population will decrease, the gar population won't have anything to limit their population, so they will increase fast. The crab population will decrease fast as there are more gars to eat them. The duck population will decrease slightly as the gar is eating more crabs then the duck
Avery's experiments showed that bacteria are transformed by “transforming principle” – DNA.
When Griffit in his experiments showed that R-strain bacteria (non-virulent) could be transformed by the heat-killed S bacteria, and become virulent, scientists assumed that there is some kind of “transforming principle” that is involved.
Avery and his colleagues cultured heat-killed S cells and tried t separate cellular components that could possibly be that “transforming principle”. Molecule of DNA gave positive result in a chemical test and also when enzymes able to degrade DNA were introduced, the transforming activity was eliminated.
The area affected by the ship that were involved in an accident is = 333 million liters
An oil spill can affect bird nesting near a contaminated body of water through its food chain.
<h3>What is oil spillage?</h3>
Oil spillage is defined as the release of used or oil wastes into a water body through a tanker, offshore drilling rig, or underwater pipeline.
The area affected by the ship that were involved in an accident can be calculated by the addition of the various areas affected by the tanker, ship and super tanker.
That is, 32,000 + 1,200,000 + 332,000,000
= 333,232,000
Which is approximately 333 million liters.
A bird that is nesting near the contaminated body of water can be affected through its food chain.
This is because birds which depends on fish can eat fish for this contaminated water which must have accumulated some level of harmful organic substances on its body surfaces.
Therefore when eaten by the bird their health would be affected negatively.
