Vacuoles are essentially sacs surrounded by a membrane. They are used by cells as temporary storage sites. They often store food, enzymes, and other materials needed by the cell, and some vacuoles store waste products.
Answer:
monoamine oxidase inhibitor
Explanation:
MAO is an intramitochondrial enzyme that is responsible for the breakdown of intracellular dopamine,norepinephrine and dopamine.MOA INHIBITORS is responsible for inhibiting monoamine oxidase as a result there is an increase concentration of monoamines at the synapse.
Answer:
e) unicellular, colonial, or multicellular.
Explanation:
Protists originates from the Kingdom Protoctista. They comprise of organisms that are unicellular (Amoeba) or unicellular-colonial (volvox) in nature and which have no tisssues, therefore they are at the cellular level of organization.
Examples include, Amoeba, Paramecium, Euglena, Slime mold, Kelp, Diatoms, DInoflagellates. etc.
Some of them are also considered to be multicellular eukaryotes e.g slime molds, red algae etc. Eukaryotic organisms are organisms that possess cells containing a nucleus.
Characteristics in which protists exhibit varies from one species to the other.
For example, the mode of nutrition in eukaryotic algae are autotrophic in nature, in amoeba, they are gifted with pseudopods(false feets) in which they used to engulf prey(a term known as phagocytosis) therefore making them to be heterotrophic in nature.
In protist, locomotion varies from one organism to another. For example, in Amoeba , locomotion is achieved by extending and retracting pseudopods, Euglena are flagellated in nature , hence they move with the flagella. In Paramecium that are ciliated in nature, they move by propelling their cilia. etc.
The answer is it begins at the PYLORIC SPHINCTER and ends at
the ILEOCECAL SPHINCTER. The pyloric sphincter is a group of smooth muscle at
the joint between the pylorus of the stomach and the duodenum of the small
intestine. It plays a vital role in digestion, where it acts as a valve to
controls the flow of moderately digested food from the digestive to the small
intestine. Ileocecal is a sphincter muscle valve that split up the small
intestine and the large intestine.
