Answer:
Depending on the stimulus, graded potentials can be depolarizing or hyperpolarizing. Action potentials always lead to depolarization of membrane and reversal of the membrane potential. Amplitude is proportional to the strength of the stimulus. ... Duration of graded potentials may be a few milliseconds to seconds.
Explanation:
We can control pollution by
(i) By Making workplaces no-smoking zones and banning cigarettes advertising.
(ii) By Strictly penalties for consumers and firms who break the regulations.
(iii) By Setting minimum standards in the workplace for health and safety.
An alternative approach to this experiment would be the use of Spectroscopy. Instead of trying to visualize and guess the fraction with the most intense color, the exact fraction could be found with Spectroscopy. A range of fractions that are the most intense are measured with the absorbance value for each one. The fraction with the highest absorbance value will be the most intense fraction.This method guarantees that the <span>correct retention volume is recorded.</span>
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: C
Explanation: I'm not one hundred percent sure I know the context of this question, but biodiversity in an ecosystem means there's a wide variety of organisms, and a hotspot I assume would be an area that has an unusual amount of diversity.
