Answer:
C. inhibiting the breakdown of neurotransmitters in the brain
Explanation:
Monoamino oxidase (MAO) facilitates the break down and removal of neurotransmitters like nor-epinephrine, epinephrine, serotonin in brain which have excitatory effects on neurons. When these neurotransmitters are degraded by MAO, this would lead to decreased excitatory level of neurons and it will become less functionable as seen in most of the patients suffering from depression, panic disorders, social disphobia and some neurodegenerative disease.
Monoaminooxidase Inhibitors prevents the degradation of above mentioned neurotransmitters which leads to increasing their levels and concentration which allows them to work and influence on neurons effected by depression.
Answer:
Fossils generally helps in relative dating of rocks.
The Trilobites are considered the oldest in this rock sequence when we apply the principle of superposition of strata.
The principle states that "in an undeformed/undisturbed sequence of rock, the oldest is always at the bottom while the youngest is on top" .
This principle therefore explains why the Trilobites at the base are considered the oldest.

A) All Cells
An organelle is a structure within the cytoplasm of a eukaryotic cell that is enclosed within a membrane and performs a specific job. Organelles are involved in many vital cell functions. Organelles in animal cells include the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, vesicles, and vacuoles.
