A waterborne pollutant can have different effects on aquatic life depending on the nature of the pollutant. A pollutant at lower levels can have minimal or no effect on aquatic life. However, when the concentrations of the pollutant are high, the population of aquatic organisms can be greatly reduced. There are also times when pollutants at lower concentrations cause significant damage. An organism can consume another organism that has absorbed small amounts of the pollutant. As the consumer takes in more of the contaminated organism, the pollutant is magnified in the body of the consumer resulting in lethal concentrations. This is called biomagnification.
Answer: True.
Explanation:
All the organism cells read the same genetic blueprint. So they all have the exact same DNA.
D, because she wants to monitor the wildlife.
Answer:
Natural selection produces changes most quickly in species with short reproductive cycles.
Explanation:
Natural selection implies a process of changes in the genome of species, induced by their environmental conditions, which allow them to survive. The processes of natural selection usually manifest themselves after long periods of time and are synonymous with adaptive evolution.
Since natural selection depends on the changes observable in successive generations within a species,<u> in organisms with short reproductive cycles the changes promoted by natural selection could be observed most quickly</u>.
