Answer:
Superbugs are bacteria that are resistant to Antibiotics.Bacteria becomes resistant to antibiotics and carry genes that allow them to survive in harsh conditions. The infection caused by these bacterias are difficult to treat.These antibiotic resistance can be trasmitted from one bacteria to its offspring.
Explanation:
Answer:
Oxygen
Explanation:
Oxygen is the by product of photolysis during photosynthesis whereby water molecules are split to form protons (H+ ions), electrons and oxygen (by product).
Oxygen is not needed during any of the reactions in photosynthesis and Calvin cycle and will not affect the rate of photosynthesis or possibility of photosynthesis occurring. However, it will affect the process of aerobic respiration instead.
Carbon dioxide is needed in carbon fixation during the Calvin cycle. Without it, 6 carbon sugars cannot be formed.
Water is needed for photolysis to produce protons (maintain the electrochemical gradient) and electrons (to replenish lost electrons)
Chlorophyll are pigments that harvest light energy to excite electrons produced from photolysis of water to be passed down the electron transport chain.
Light is needed as a source of energy to energise the electrons
I think the answer is C) human activity
Answer:
Serovars
Explanation:
Serovars refer to the different strains of a species of microbe that differ from each other with respect to the antigenic composition of a specific structure such as polysaccharides of the cell wall. Serovars are identified suing appropriate antiserum.
For example, the bacterial species <em>Streptococcus pneumoniae</em> have as many as 90 serovars that differ from each other with respect to antigens present in their capsules. These different serovars are identified by using antiserum for specific capsular types which in turn would induce capsular swelling.
