Analyze the following statements and select those that correctly reflect the characteristics of archaea.
Metabolically, archaea are the most diverse group of organisms on the planet
surviving in extreme conditions such as extreme heat high salt levels extreme pH
and high pressure
Archaea are strictly environmental microbes they are not part of the normal biota of
higher organisms
Bacteria and archaea are both classified into Kingdom Monera because they share the
same cell wall chemistry te they all contain peptidoglycan
The extreme halophiles are not only tolerant to high salt levels, they require it to grow.
Archaea are genetically more similar to bacteria than to eukaryotes

Twind is considered to be an abiotic factor because it.?

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.

Jason adds the antibiotic penicillin to a bacterial culture. the bacteria develop genetic modifications in their genome, which gives them resistance to the antibiotic penicillin. what caused this genetic modification?
