Answer:
High, Low
Explanation:
Wind blows air on the surface of the earth from a high pressure center to a low pressure center (this is depicted in the image attached). The area between the two "centers" is referred to as pressure gradient. The warm air in the region of the low pressure center then rises up into the atmosphere. The warm air then cools up in the atmosphere and then passed down back to the earth's surface
Answer:
The earliest known life-forms are putative fossilized microorganisms, found in hydrothermal vent precipitates, that may have lived as early as 4.28 Gya (billion years ago), relatively soon after the oceans formed 4.41 Gya, and not long after the formation of the Earth 4.54 Gya.
Explanation:
If you are startled by the sound of a loud explosion, the sympathetic nervous system will become dominant. The sympathetic nervous system is responsible for regulating not only the functioning of the visceral organs (kidneys, digestive system and circulatory system) but also all the automatic functions of the organism, such as breathing, circulation, digestion and elimination.
