Select the correct answer. Flagellates are microbes that have a rod-shaped flagellum that helps with their locomotion. Certain flagellates reside inside termites. These
flagellates provide enzymes for the termites to digest cellulose, which helps them survive. In turn, the termites provide nourishment to these
flagellates. Termites need cellulose for their survival, and flagellates obtain nutrition only from termites. Which statement can be true about the
association between these microbes and termites?
O A.
The flagellates share a facultative mutualistic association with the termites.
O B. The flagellates and termites share an obligate mutualistic association.
O c. The flagellates share an obligate parasitic assoclation with the termites.
O D. The flagellates and termites share a commensal association.
O E. The flagellates and termites share a facultative parasitic association.

Despite the differences in mature plant cells, all of them are derived from meristem cells. the three major types of tissue systems develop from the meristem. meristems develop cells in all but which tissue?

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.
