Answer:
A
Explanation:
Tilling agitates the topsoil and removes ‘unnecessary’ vegetation so the main crop can grow without competition. Tilling improves soil aeration and drainage for plants to grow well. Nonetheless, it can lead to other consequences such as soil erosion because it loosens the soil and makes it easy to be carried away by wind and water.
Answer:
1. Endocrine
2. Exocrine
Explanation:
The pancreas serves as both endocrine and exocrine gland.
The pancreas is an exocrine gland as the pancreatic acini produce digestive enzymes that are delivered to the small intestine through a network of ducts. The glands that release their secretions by ducts are called exocrine glands.
Islets of Langerhans scattered among pancreatic acini serve the endocrine part of the pancreas. The alpha cells of pancreatic islets secrete hormone glucagon while the beta cells of the islets secrete the hormone insulin directly in the bloodstream. Likewise, the delta cells of pancreatic islets secrete hormone somatostatin. The ductless glands that release their secretions directly into the bloodstream are known as endocrine glands.
