The biosphere integrates all living organisms, the interactions between them and it is very important part from the Earth's ecosystem. Ecologists are particularly concerned about the impact of human activities on following four processes of the biosphere:
1. exchange processes: the way land surfaces exchange energy, water and mass and the transport of energy, water and carbon dioxide.
2. dynamics of airflow
3. <span>biogenic emissions of trace gases and biomass burning particles
</span>4. global carbon cycle
Photosynthesis has a role in the cycling of matter and flow of energy into and out of organisms. The flow of energy and cycling of matter can be traced. The chemical reaction by which plants produce complex food molecules (sugars) requires an energy input (i.e., from sunlight) to occur hope this helps :)
Possible contaminate will be Proteus or Salmonella. To differentiate the two genera urease test can be accomplished. However, urease test, Proteus will produce a positive test result.
This test can be done to determine the ability of an organism to split urea. The principle of urease test is that urea is the product of decarboxylation of amino acid. Splitting of urea via hydrolysis will produce ammnonia and CO2. The CO2 produce allows the formation of bubbles.
Answer:
Intramuscular
Explanation:
Intramuscular is a method of administering injection directly into the muscles for effective functioning.
Long acting penicillin are administered intramuscularly because of penicillin sensitive microorganisms that are subsceptible to low serum levels which is associated with penicillin dosage in the body and penicillin Has low level of solubility therefore it is slowly released into the muscles sites.
