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:
D. Type in human immune system + HIV effects.
Explanation:
Since Angela is focusing more on the human immune system and the effects of HIV could have on it, the keywords combination that would produce the most relevant search result has to contain human, immune system and HIV effects.
Option A has human, body systems and HIV, immune is absent.
Option B contains immune system and human, no HIV effects.
Option C contains HIV and immune system, no human.
All the options are lacking in some ways and will not produce the most relevant search results.
The correct option is D. It has all the necessary keywords.
The best answer is C.
Plant cells are surrounded by a cell wall and have chloroplasts whereas animal cell do not.
The cell wall is a covering that is rigid whose main purpose is to protect the cell and give structural support as well shape to the plant cell. The equivalent of a cell wall in animal cell is the cell membrane, which has distinct differences from the plant cell wall.
Chloroplasts are plant cell organelles which carry out photosynthesis by which plants make their own food. These are absent from animal cells because animals do not make their own food, they ingest it from external sources.
