Answer: Plants perform photosynthesis more efficiently when carbon dioxide is abundant. This in turn reduces the amount of carbon dioxide in the atmosphere and increases the amount of oxygen
No hypothesis test is 100% certain. Because the test is based on probabilities, there is always a chance of making an incorrect conclusion. When you do a hypothesis test, two types of errors are possible: type I and type II. The risks of these two errors are inversely related and determined by the level of significance and the power for the test. Therefore, you should determine which error has more severe consequences for your situation before you define their risks.Type I errorWhen the null hypothesis is true and you reject it, you make a type I error. The probability of making a type I error is α, which is the level of significance you set for your hypothesis test. An α of 0.05 indicates that you are willing to accept a 5% chance that you are wrong when you reject the null hypothesis. To lower this risk, you must use a lower value for α. However, using a lower value for alpha means that you will be less likely to detect a true difference if one really exists.Type II errorWhen the null hypothesis is false and you fail to reject it, you make a type II error. The probability of making a type II error is β, which depends on the power of the test. You can decrease your risk of committing a type II error by ensuring your test has enough power. You can do this by ensuring your sample size is large enough to detect a practical difference when one truly exists.

Explanation:
Answer: The period known as classical antiquity began with the emergence of the city-states of ancient Greece. Later, the Roman Empire came to dominate the entire Mediterranean basin. The fall of the Roman Empire in AD 476 traditionally marks the start of the Middle Ages.
Explanation:
Rivers like the Nile and Colorado which rise in moist regions and then flow through arid landscapes are called exotic streams.
Special streams are people who originate in a damp region but waft via an arid area. Such is the case of the Nile and Colorado Rivers. The headwaters of the Nile River is inside the moist Ethiopian Highlands and travels thru the eastern portion of the Sahara desolate tract on its manner to the Mediterranean Sea.
When a river like the Orange (or Gariep) flows via a wet vicinity and then a dry location, it's far called an extraordinary river. because the Orange includes one of these big volumes of water, it flows thru a completely lengthy distance of the dry Northern Cape and still drains into the ocean.
In maximum landscapes the land isn't always perfectly flat—it slopes downhill in a few directions. Flowing water unearths its manner downhill, to begin with as small creeks. As small creeks glide downhill they merge to form large streams and rivers. Rivers ultimately emerge as flowing into the oceans.
