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.
The elephant can transform woodlands into grasslands which benefits other species for survival.
The major difference between the flow of matter and of energy is that the flow of matter occurs in a cyclic manner i.e. it is recycled, however, the flow of energy in an ecosystem is unidirectional which means, it is not recycled. The flow of matter follows the following path
1) Decomposers release nutrients when they break down dead organisms
2) The nutrients are taken up by plants through their roots
3) The nutrients pass to primary consumers when they eat the plants
4) The nutrients pass to higher-level consumers when they eat lower-level consumers
5) When living things die, the cycle repeats
In case of flow of energy, the energy flows through an ecosystem in one direction, from photosynthetic organisms to herbivores to omnivores and carnivores and decomposers, less and less energy becomes available to support life. This loss of usable energy occurs because each energy transfer results in the dissipation of some energy into the environment as heat
The lower density water occurs in the deep zone of the ocean.
This region of water is cold and stable. Cold water has a higher density as the water molecules are packed more closely together, so they occupy less volume. The difference in density of the regions of ocean is responsible for convection currents.
