Answers

Answer:

large floating booms, skimmer boats, and genetically engineered bacteria

Explanation:

Skimmers are used in the clean up of oil spills it makes use of containment skims that act like a fence and the surface of water and prevent the oil spill from moving or spreading across the water surface. It contains the oil into a particular place. Floating booms helps in the sucking out of oil in the confined area, its act like a vacuum pump and suck out all the oil spills available in the areas confined by the skimmers.

Bioremediation involves the use of microorganisms to clean up spills this micro organism breaks down this petroleum product into harmless substance through their metabolic activities. Genetically modified Bacterial can be use for this purpose to help break down this hydrocarbons and make them less toxic.

warm, moist air rises
warm, dry air descends

Two insect groups vary genetically by two genes. When put together, they were able to reproduce and produce offspring that could also breed. Which best describes this insect population?
The insects experienced geographic isolation.
The insects experienced reproductive isolation.
The insects are different species.
The insects are the same species.

Answers

The answer is D. The insects are the same species.

The insects are the same species best describes this insect population.

What is reproductive isolation?

The fact that the two insect groups were able to reproduce and produce offspring that could also breed indicates that they are not experiencing reproductive isolation. Reproductive isolation occurs when two populations of organisms can no longer interbreed due to genetic or behavioral differences.

Since the two insect groups can interbreed and produce viable offspring, it suggests that they are not different enough genetically to be considered different species.
