Answer:
More heat in the atmosphere, less absorption of greenhouse gases on Earth, and solar and volcanic activity may contribute to an increase in global average surface temperatures.
Explanation:
The answer is A. The main driver of the convention in atmospheric
circulation is the suns energy. When the sun heats the earth, the atmosphere directly below the sun gets heated more
and faster compared to other regions causing an area of low pressure. This hot
air mass rises and is replaced by cooler air masses (from high-pressure regions)
from neighboring regions. This, essentially,
causes winds and air currents.
Answer:
The correct answer is option b, that is, enteroendocrine cells.
Explanation:
The specialized cells of the pancreas and the gastrointestinal tract exhibiting endocrine function are termed as enteroendocrine cells. These cells generate gastrointestinal peptides or hormones in response to a distinct kind of stimuli and discharge them into the bloodstream for the systemic effect. These are the most varied endocrine cells found within the body.
The intestinal enteroendocrine cells produce somatostatin, cholecystokinin, motilin, enteroglucagon, and neurotensin hormones. The G cells present within the intestine produce gastrin. In the gastric glands, the gastric enteroendocrine cells are present, which produce histamine, and others like cholecystokinin, alpha and gamma-endorphin, somatostatin, and others.
In the islets of Langerhans, the pancreatic enteroendocrine cells are present, which produce hormones like ghrelin, amylin, somatostatin, and pancreatic polypeptide.

Tiktaalik roseae was discovered in sediments on Ellesmere Island in Nunavut, Artic Canada (Ahlberg and Clack, 2006). The sediments it was found in are from what is known as the Fram Formation, which is thought to be deposits of lowland streams (Murphy, 2005). hope it helps
