Answer:

B. everything should remain the same between experimental groups

Explanation:

The control group, in one experiment, is characterized by individuals who will not receive the factor being tested in the experiment, but will also be evaluated at the same time points as the subjects in the intervention group. For example, if you have bean plants and want to do an experiment where you will evaluate the effectiveness of a fertilizer on bean plants, you will apply fertilizer on 9 bean plants while one plant will be maintained without fertilizing it. However all plants will be treated the same (except for fertilizer application) and will be evaluated in the same way. The fertilizer is the factor that is being tested in the experiment, the plant that did not receive it is the control group.

What are the two recognized means of preventing injury during electrical equipment operation?
baherus [9]
Grounding and insulation will be the two most recognized means of preventing injury during an electrical equipment operation. The workers should always place a non-conductive material like plastic around the conductor of electricity. When grounding, there needs to be a direct connection to either a cold water pipe or even metal. Without doing either grounding or insulation, there is a chance of burns, shocks, fire, and in extreme cases death.

What is an example of eukaryotic gene regulation? Why is gene regulation necessary or advantageous?
Salsk061 [2.6K]
Gene regulation in eukaryotic cells is regulated by repressors as well as by transcriptional activators. Like their prokaryotic counterparts, eukaryotic repressors bind to specific DNA sequences and inhibit transcription. Any step of gene expression may be modulated, from the DNA-RNA transcription step to post-translational modification of a protein. The following is a list of stages where gene expression is regulated, the most extensively utilised point is Transcription Initiation: Chromatin domains.

What does planarian regeneration tell us about human regeneration?
AlekseyPX
A planarian can regrow any missing body part. Truth be told, in the event that you take a planarian and excise it into a few little pieces, every last one of those body sections can recover into an entirely different worm.
