The earliest modern humans in Australia, dating to 50 - 40,000 yBP, were found at Lake Mungo. Early modern humans moved into North and South America because of population increase, competition for food and climate change. Modern humans likely migrated to the Americas via walking across the Being land bridge.
<span>A failure of homeostasis -- the balance of essential physiological states -- means disaster for the organism. Failure to maintain body temperature leads to hypothermia or heatstroke. Failure to maintain energy balance can result in obesity and diabetes. Failure to maintain calcium balance in the blood leads to hypocalcemia or hypercalcemia. Failure to maintain water balance results in dehydration or hyperhydration. </span>
A cofactor<span> is a non-protein chemical compound or metallic ion that is required for a protein's </span>biological<span> activity to happen. These proteins are commonly enzymes, and </span>cofactors can<span> be considered "helper molecules" that assist in biochemical transformations.</span>
The answer is A. Condensation is when a gas becomes a liquid. It happens when a gas, like water vapor, cools down. ... In condensation, matter changes from a gas to a liquid. All matter is made of tiny moving particles called molecules.
We define chemical reaction is a process in which old bonds break and new bonds are formed . So from the definition you can get the result easily
