I'd go with this one: b.) Meiosis I separates tetrads, and meiosis II separates sister chromatids. As it is correctly describes the difference between meiosis I and meiosis II.
The correct answer is: MAO inhibitors.
MAOI - monoamine oxidase inhibitors are antidepressants that affect the enzyme called monoamine oxidase which normally removes the neurotransmitters norepinephrine, serotonin and dopamine from the brain. As a consequence, neurotransmitter’s activity is increased. MAOIs interact with tyramine, amino acid found in food such as cheese, smoked sausage, and red wine. Tyramin eis normally regulated via MAO. So, when the MAO is inhibited via MAOI, tyramine reaches high levels, causing the blood vessels to narrow and resulting in critically high blood pressure.
Answer:
2)
Explanation:
The positive control is the treatment where bacteria grew without lead. Since positive control indicates the presence of bacteria in the experimental conditions, it is possible to confirm that they only death in presence of this metal. However, it is important to note that it is imperative to repeat this experiment three times and also to include a negative control in order to confirm these results.
Answer:
Phase 3
Explanation:
Phase 3 of the systems development life cycle describes the desired features and operations of the system. The objective of the systems design phase is to transform all requirements into detailed specifications covering all aspects of the system. It should also assess and plan for security risks. Finally, approval to progress to the development phase must be granted to complete the systems design phase.
