Answer:
The most accurate measurement is 2.829 cm.
Explanation:
We can round the decimals to a certain accuracy in order to make further calculations easier.To round a number to the nearest hundredth ,check the next place value to the right (the thousandths). If it's less than 5, remove all the digits to the right. If the place value is 5 or greater than 5, just add 1 to the previous digit (the hundredths place digit) and drop all other digits to the right.
In other words, to round off a decimal number, the procedure is as follows; if the digit to the right of the required number is a 5 or greater, add 1 to previous digit and drop all the remaining digits. If the required number is less than 5, do not change the previous digit and remove all the remaining digits.
Here, a piece of metal with a length of 2.83 cm was measured using four different devices. The obtained measurements are 2.837 cm, 2.829 cm, 2.812 cm and 2.805 cm.
Thus, the first measurement 2.837 cm can be round off to 2.84 cm. The second measurement 2.829 cm can be round off to 2.83 cm. The third measurement 2.812 cm can be round off to 2.81 cm and the fourth measurement 2.805 cm can be round off to 2.81 cm.
So the most accurate measurement is the second one, 2.829 cm which can be round off to 2.83 cm.
The correct answer is option C
The reaction of cellular respiration and burning of fossil fuel needs carbon. Fossil fuel are like coal is made up of carbon. Organic compounds are made up of carbon(abundant), hydrogen and oxygen in small amounts.
The cellular respiration is the process by which the body obtains energy in the form of ATP by the breakdown of carbohydrates which is also a carbon compound.
Answer:
Parts of the U.S. state of Alaska and the countries of Canada, Greenland, Iceland, Norway and Russia are all in the Arctic tundra biome. Regardless of how cold and bleak the weather may be in the northern contiguous states in the middle of winter, technically, the tundra does not extend below northernmost Canada
Explanation:
Answer: Armored fish
Explanation:
The earliest known fossil vertebrates were heavily armored fish discovered fish in rocks from the Ordovician period.
The fossils shows the path from the early aquatic life to the vertebrates, vertebrates to mammals.
The fossils shows that it is vertebrate and are the oldest known fossil ever known. The fossils of the animals and plants helps to known the behavior of the past time and based on that research and study is done.
