Answer:
The correct answer would be option A.
Explanation:
Gina's model lacks many important factors about the particular study of damage to tree bark in the forest. This model does not explain the number of animals entering a particular area of forest.
This model does not tell, how much damage has been done. It also fails to tell what type of damage the tree has faced. It does not explain what type of bacteria evolved or carried by the animal.
Thus, the correct answer would be option A.
Answer:
Catalase
Explanation:
Catalase test is used to detect the presence of enzyme catalase.
Catalase is an enzyme that is formed by microorganism that lives in oxygen saturated environments so that there will be the break down of any toxic that comes with oxygen and hydrogen peroxide. This enzymes helps to differentiate catalase producing enzymes like staphylococci from bacteria that produce non-catalase like streptococci
If a scientist wanted to compare the exact number of organisms at each trophic level within a desert ecosystem, the pyramid he or she would use would be the pyramid of numbers. The pyramid of numbers presents the population of organisms (individually) in each trophic level in a certain ecosystem.

brain chemical <span>sterase </span>cannot be used to help produce the breakdown of other brain chemicals,like nor epinephrine<span>? </span>A<span>. </span>It would require a level of (stimulation of action/making active and effective) energy too high for brain chemical<span>sterase </span>to react with other brain chemical<span>s. </span>B.Binding with an alternate brain chemical would stop the reaction of the enzyme with brain chemical<span>.

Answer:
b. transcription
Explanation:
Transcription is the process by RNA is synthesized from DNA. It is carried out by RNA Polymerase enzyme which uses DNA as template. It builds new RNA strand in 5' to 3' direction from the template strand. A gene to be transcribed has a promoter region in front of it. RNA Polymerase is required to bind to this region to begin transcription. Once it binds to this region, the two DNA strands separate locally starting the process of transcription.
Rifampin inhibits RNA transcription by inhibiting bacterial DNA dependent RNA Polymerase. It binds to the beta sub unit of RNA Polymerase which does not allow it to properly bind to the promoter region thus halting transcription process.
