Sample Response:
Bacteria are helpful because they produce oxygen, which our bodies need to breathe, and they help us to digest the food we eat. Bacteria are also helpful because they are used in medicine to help us overcome disease. Bacteria are harmful because they can cause tooth decay and illnesses that can be either common or quite serious.
This is a sample response, so it's 100% correct. Peace!
Answer:
Current Air Temperature
The current air temperature plotted to the nearest whole degree Fahrenheit.
Dew Point Temperature
The dew point temperature plotted to the nearest whole degree Fahrenheit.
Sky Cover
The total amount of clouds in tenth. Plotted in the station circle according the the following table.
Wind Speed And Direction
The wind direction is plotted as the shaft of an arrow extending from the station circle toward the direction from which the wind is blowing. The wind speed is plotted as feathers and half-feathers representing 10 and 5 knots, on the shaft on the wind direction arrow. See the following table.
Visibility
The visibility plotted in fractions of a mile. For values above 10 miles, the values are omitted from the map.
Sea Level Pressure
The barometric pressure in tenths of millibars reduced to sea level. The initial 9 or 10 and the decimal points are omitted.
ex: plotted = 982, actual = 998.2 mb
ex: plotted = 012, actual = 1001.2 mb
Pressure Tendency
The pressure change in the past 3 hours preceding the observation. Plotted to the nearest tenth of a millibar. The plotted symbol characterizes the change in pressure according to the below chart.
Answer:
Nucleotide bases.
Explanation:
Unique sequences of bases makes up a nucleotide. These nucleotide sequencing are used by DNA as a genetic code of information that determines type of cells, proteins and the whole organismal structure.
There are four nucleotide bases, Adenine and guanine termed purines are big, cytosine and thymine called pyrimidines are small. A purine pairs with a pyrimidine, such that adenine pairs with thymine and guanine pairs with cytosine. The bases are the same but each DNA uniqueness lies in the sequence of base pairing.
