Sally and Maria hypothesized that earthworms lived only in dark, damp places. They measured a one-meter square in a shady spot n
ear a stream. They dug through the soil and collected earthworms. They collected 43 worms. They repeated the experiment in several locations, sunny and dry included. They found the most worms in the shady, damp plot near the stream. Several other groups of science students carried out the same experiment and got similar results. This is an example of A) bias.
B) repetition.
C) replication.
D) validity.
Replication in experiments is the process by which the entire experimental process is repeated as done by the previous scientists, keeping in mind all the necessary requirements and experimental conditions so as to determine the correctness of the experimental methodology, relationship between the variables, correctness of the results and other parameters.
Here, several group of students are repeating the same experiment and getting the same results this process is called as replication.
Because other scientists did the experiment and got the same results it's replication. the other group replicated the experiment and we're able to replicate the results
Proteins and DNA replications are made from two phases the transcription and translation. Transcription happens in the nucleolus, where it produces mRNA and translation in the ribosomes.

The appropriate answer is B. Throughfall. These nutrients are transported via the process of throughfall where rain flows from leaves to the ground. Rainforests receive high annual rainfall. The leaves are also designed to funnel water to the ground soon after a shower. Leaves are equipped with drip tips to allow water to roll of leaves easily. Any particles deposited on leaves are going to be washed to the forest floor by frequent rainfall that occurs here.
