The carbon atoms gradually transform into another type of carbon atom. they can tell the age by the percentage of each type of carbon an artifact has.
The Chloroplast possess their own DNA. This organelle has green orpiment called Chlorophyll.
Answer:
Some examples of important nonliving things in an ecosystem are sunlight, temperature, water, air, wind, rocks, and soil. Living things grow, change, produce waste, reproduce, and die. These living things interact with the nonliving things around them such as sunlight, temperature, water, and soil.
Explanation:
Nonliving factors determine what living things can be supported in an ecosystem. The living creatures in a habitat affect the nonliving elements within the community. For example, plants can affect soil chemistry or certain algae can influence water chemistry.
1. Griffith in his experiment used two related strains of bacteria (Streptococcus pneumonia), known as R and S and mice, trying to develop a vaccine against pneumonia. R strain-formed nonvirulent, rough-edged colonies
S strain- rounded and smooth colonies, with sugar protection coat, virulent
Mice that were injected with S strain developed pneumonia and died.
But, when mice were injected with heat-killed S strain it did not cause disease in mice.
The next part of experiment is the injection of combined harmless R bacteria with harmless heat-killed S bacteria. The result was that the mouse developed pnenumonia and in blood sample from the dead mouse, living S bacteria were found.
2. From his experiment, Griffith concluded that injected together, R strain and S strain bacteria most likely “communicate”. The R-strain bacteria took "transforming principle" (we know today that this is genetic material DNA) from the heat-killed S bacteria which allowed them to "transform" into virulent bacteria.
Clearly, an IV solution of D5W (5% dextrose in water) is a clear solution, not light yellow. The nurse should check the patient's chart if the IV fluid ordered is really D5W. If it is confirmed that D5W is the IV fluid of the patient, then the nurse should replace the IV bag with a new one with clear contents and make an entry in the chart about what was observed and why the previous bag was replaced.
