Hello!
I am not given any options, but I can explain the question to you.
A biotic factor is anything that is living in the ecosystem, such as animals, plants, fungi, and bacteria.
An abiotic factor is anything that is not living but the ecosystem needs to thrive, such as sunlight, oxygen, good temperature, living space, etc.
For example, let's say we had options below.
A. Sunlight
B. Living Space
C. Moss
D. Oxygen
As you can see, all of our options are beneficial to an ecosystem, but moss is the only one that is living. In this scenario, our answer would be C. Moss, as it is a biotic but not an abiotic factor.
I hope this helps!

Answer:
They are secreted from pancreatic cell through exocytosis.
Explanation:
Beta cells of the pancreas are responsible for the synthesis and release of insulin in the blood. Insulin is released in the blood when the blood glucose level reaches above the normal blood glucose level.
Once the beta cells are insulated the insulin is released from the cell by the process of exocytosis and reaches to blood capillaries of islets. Insulin is made up of A and B chain when released in the blood but in proinsulin, a C chain is also present which is released in mature insulin.
Therefore exocytosis is responsible for releasing insulin from the Beta-cell of the pancreas.
