29. In an eighth-grade science class, there are four lab groups. Group 4 designs an experiment to find out how light affects the germination rate of radish seeds. The tudents in Group 4 write out their procedure and conduct their experiment. They discover inconsistencies in their data and decide to increase the number of trials to
obtain multiple data sets. Which of these most accurately describes how this should be done?
O Group 4 should repeat their procedure at least three times.

Name the two stages involved in protein synthesis and explain what occurs in each of the two stages. be sure to also indicate where each process takes place. plz don't give one sentence answers : d

Rease is an enzyme used by plants to break down urea (a nitrogen-containing compound) into carbon dioxide and ammonia. urease urea > > > carbon dioxide and ammonia ammonia is broken down by plants into a nitrogen source plants need to grow. thus, plants could not use urea as a nitrogen source unless it was first converted to ammonia. in soybean plants there are two different kinds of urease, one produced in the seeds and the other produced in the leaves of the plant. three types of soybean plants were used in a set of experiments: normal soybeans and two mutant strains, one lacking the urease in the seeds only (strain 1) and one lacking urease in the leaves only (strain 2). experiment 1 separate areas in a field were planted with normal, strain 1, and strain 2 soybeans. all types of soybeans appeared to grow, flower, and produce seeds equally well. there were no externally detectable differences among the strains. experiment 2 small pieces of plant leaves of equal weight were obtained from each type of soybean plant and separately placed on media in culture dishes. tissue growing in this way will become an unorganized clump of cells referred to as callus. to provide a controlled nitrogen source, half the tissue samples of each type were placed on media containing urea, and the other half of the samples were placed on media containing ammonia. after 30 days, the weight gain for each of the callus samples was determined. results are shown in the table below.
