Answer:
they carry out experiments to understand it
Explanation:
Scientists raise hypotheses which are tested by experiments made under controlled conditions in order to explain a particular topic. When a hypothesis is confirmed by the experimental data, the evidence obtained from this experiment provides the basis to increase the scientific knowledge about a particular issue. In consequence, experimentation can be considered as a critical step in the scientific method and research aims to advance knowledge of a particular phenomenon by confirming a hypothesis, which must be testable (i.e. verifiable as a result of further experimentations).
The correct answer is letter A, the increased nitrates from the fertilizers leech into the water and cause algal blooms, which take oxygen out of the water and this suffocates fish.
This is one of the many chain reactions that agricultural farming brings to the environment, and it will be very common through the years as people have not figured out a safer way to protect crops.
Pressure would be my best guess, since no choices were given.
Evolution is a slow change that occurs over time

Answer: (I hope you can understand this)
Type of operon: Trp
It’s a repressible operon
Lac
It’s an inducible operon.
Environment:
Trp
It’s deactivated when tryptophan is present in the environment.
Lac
It’s activated when lactose is present in the environment.
Repressor protein:
Trp
It’s activated by tryptophan.
Lac
It’s inactivated by lactose.
Transcription:
Trp
Tryptophan binds to the repressor protein, activating it.
Lac
Lactose binds to the repressor protein, deactivating it.
